Abstract:
Clinicians can use behaviour change techniques effectively in routine consultations in healthcare settings, including dentistry. Professional guidelines support their use for preventing and managing a range of dental diseases. Theory and evidence from behavioural science can inform effective behaviour change interventions. This article examines the relevance of these techniques to the whole dental team and how they can be implemented within routine dental consultations.

Abstract:
Background Health behaviours are essential to maintain optimal health and reduce the risk of cardiovascular complications in adults with congenital heart disease. This study aimed to describe health behaviours in adults with congenital heart disease in 15 countries and to identify patient characteristics associated with optimal health behaviours in the international sample. Design This was a cross-sectional observational study. Methods Adults with congenital heart disease ( n = 4028, median age = 32 years, interquartile range 25–42 years) completed self-report measures as part of the Assessment of Patterns of Patient-Reported Outcomes in Adults with Congenital Heart disease - International Study (APPROACH-IS). Participants reported on seven health behaviours using the Health Behaviors Scale-Congenital Heart Disease. Demographic and medical characteristics were assessed via medical chart review and self-report. Multivariate path analyses with inverse sampling weights were used to investigate study aims. Results Health behaviour rates for the full sample were 10% binge drinking, 12% cigarette smoking, 6% recreational drug use, 72% annual dental visit, 69% twice daily tooth brushing, 27% daily dental flossing and 43% sport participation. Pairwise comparisons indicated that rates differed between countries. Rates of substance use behaviours were higher in younger, male participants. Optimal dental health behaviours were more common among older, female participants with higher educational attainment while sports participation was more frequent among participants who were younger, male, married, employed/students, with higher educational attainment, less complex anatomical defects and better functional status. Conclusions Health behaviour rates vary by country. Predictors of health behaviours may reflect larger geographic trends. Our findings have implications for the development and implementation of programmes for the assessment and promotion of optimal health behaviours in adults with congenital heart disease.

Abstract:
During paediatric dental treatment, cooperation by children is essential, and temperament can determine their behaviour style. This study aimed to associate temperamental traits and age with behaviour during paediatric dental treatment. This was an observational and cross-sectional study of patients aged 3–10 years. To determine the temperamental traits, an Emotionality Activity and Sociability Temperament Survey (EAS) was performed with the children’s parents. The type of behaviour was determined with Frankl’s criteria. The total scores for temperamental traits, means, and standard deviations were obtained. The chi-squared test, one-way ANOVA and Student’s t-test were applied. A total of 140 patients, who were 5 ± 2.1 years old, participated in the study. Age was determinant for negative behaviour, with a greater frequency in children ≤5 years old (p < 0.05), and a significant negative correlation between age and behaviour (rho = −0.245, p = 0.001). Patients with higher emotionality and activity presented negative and definitely negative behaviours more frequently (p < 0.01). The values for sociability and shyness were similar for positive or negative behaviours. In conclusion, the temperamental traits of emotionality and activity were more frequent in children with disruptive behaviours; therefore, conducting a survey on temperamental traits can be useful for planning behavioural approaches in paediatric dentistry.

Abstract:
Many preventive approaches in dentistry aim to improve oral health through behavioural instruction or intervention concerning oral health behaviour. However, it is still unknown which factors have the highest impact on oral health behaviours, such as toothbrushing or regular dental check-ups. Various external and internal individual factors such as education, experience with dentists or influence by parents could be relevant. Therefore, the present observational study investigated the influence of these factors on self-reported oral heath behaviour. One hundred and seventy participants completed standardized questionnaires about dental anxiety (Dental Anxiety Scale (DAS), and dental self-efficacy perceptions (dSEP)). They also answered newly composed questionnaires on oral hygiene behaviours and attitudes, current and childhood dental experiences as well as parental oral hygiene education and care. Four independent factors, namely attitude towards oral hygiene, attitude towards one’s teeth, sense of care and self-inspection of one’s teeth were extracted from these questionnaires by rotating factor analysis. The results of the questionnaires were correlated by means of linear regressions. Dental anxiety was related to current negative emotions when visiting a dentist and negative dental-related experiences during childhood. High DAS scores, infantile and current negative experiences showed significant negative correlations with the attitude towards oral hygiene and one’s teeth. Dental anxiety and current negative dental experiences reduced participants’ dental self-efficacy perceptions as well as the self-inspection of one’s teeth. While parental care positively influenced the attitude towards one’s teeth, dental self-efficacy perceptions significantly correlated with attitude towards oral hygiene, self-inspection of one’s teeth and parental care. Dental anxiety, dental experiences, parents’ care for their children’s oral hygiene and dental self-efficacy perceptions influence the attitude towards oral hygiene and one’s own oral cavity as well as the autonomous control of one’s own dental health. Therefore, oral hygiene instruction and the development of patient-centred preventive approaches should consider these factors.

Abstract:
Regular dental attendance is a key oral health behaviour. Behaviour change interventions are increasingly being used to promote positive oral health behaviours. A systematic approach to understanding behaviour has led to the development of frameworks which aim to guide the process of designing behaviour change interventions. One such framework is the Behaviour Change Wheel (BCW). This article aims to explore and identify barriers to regular dental attendance which may be targeted using behaviour change interventions based on the Capability, Opportunity and Motivation Behaviour model (COM-B) and the BCW, and suggests potential behaviour change techniques which could be utilised into a behaviour change intervention with the aim to promote regular dental attendance.

Abstract:
Dental students are the future leaders of oral health in their respective communities; therefore, their oral health-related attitudes and behaviours are of practical value for primary disease prevention. The present study aimed to evaluate oral health-related knowledge, attitudes, and behaviours of dental students in Arab countries and explore the potential sociodemographic predictors of their oral health outcomes. A multi-centre, cross-sectional study was conducted during the academic year 2019/2020 in three Arab countries: Lebanon, Syria, and Tunisia. The study used a validated Arabic version of the Hiroshima University Dental Behavioural Inventory (HU-DBI) composed of original twenty items that assess the level of oral health-related knowledge, attitudes, and behaviours, and four additional dichotomous items related to tobacco smoking, alcohol drinking, problematic internet use, and regular dental check-up The HU-DBI score ranges between 0 and 12. A total of 1430 students took part in this study, out of which 60.8% were females, 57.8% were enrolled in clinical years, 24.5% were tobacco smokers, 7.2% were alcohol drinkers, and 87% reported internet addiction. The mean HU-DBI score was 6.31 ± 1.84, with Lebanon having the highest score (6.67 ± 1.83), followed by Syria (6.38 ± 1.83) and Tunisia (6.05 ± 1.83). Clinical students (6.78 ± 1.70) had higher HU-DBI scores than their preclinical peers (5.97 ± 1.86). The year-over-year analysis revealed that dental public health and preventive dentistry courses had significantly and positively impacted the undergraduate students’ knowledge, attitudes, and behaviours. The gender-based differences were not statistically significant, with a modest trend favouring males, especially oral health behaviours. Tobacco smoking, alcohol drinking, and problematic internet use were associated with lower HU-DBI scores. In the Arab world, the economic rank of the country where the dental students live/study was weakly correlated with the students’ mean HU-DBI score.

Abstract:
Background: Evidence from cross-sectional studies implies that dental behaviours partially explain inequalities in oral health. Objective: To assess whether dental behaviours completely eliminate inequality in increments of dental caries in a sample of Finnish adults. Methods: The baseline data were collected from the Health 2000 survey, a nationally representative survey of 8,028 individuals aged 30 years or older living in mainland Finland. Four years later, 1,248 subjects were invited for oral re-examination, and 1,049 agreed to participate (84% response rate). At baseline, participants provided information on demographics, education and dental behaviours (dental attendance, tooth brushing with fluoride toothpaste, sugar consumption and daily smoking). Oral examinations at baseline and follow-up were identical. Results: Adults with basic education had significantly greater increments of DMFT (incidence rate ratio 1.41, 95% CI 1.07-1.85) and DT (incidence rate ratio 2.23, 95% CI 1.27-3.90) than those with high education. Adjusting for single behaviours attenuated but did not eliminate education inequality in DMFT and DT increments, tooth brushing having the greatest impact on inequality. Simultaneous adjustment for all behaviours eliminated the significant relationship between education and caries increment. Conclusions: Accounting for important dental behaviours appears to explain all education inequality in dental caries in Finnish adults. The results should be interpreted with caution when applied to less egalitarian populations.

Abstract:
Background: Pregnant women are at risk of oral health problems. This qualitative study aims to understand dental care-seeking behaviours of pregnant women and their oral health-related information acquisition, to identify barriers to and motivators for, dental visits, and further explore their expectations and possible strategies to improve oral health care during pregnancy. Methods: Semi-structured interviews were conducted with 30 pregnant women (after 32 gestational weeks) enrolled in the antenatal care programme in a public hospital in Hong Kong. Two main areas of interest were probed: Dental care-seeking behaviour and oral health information acquisition. Their expectations and suggestions on oral health care service for pregnant women were also explored. An inductive thematic approach was adopted to analyse the data. Results: Pregnant women’s dental care-seeking behaviour was deterred by some internal factors, such as misunderstandings on oral health, and priority on other issues over oral health. External factors such as inconvenient access to dental service during pregnancy also affected their care-seeking behaviours. Oral health information was passively absorbed by pregnant women through mass media and the social environment, which sometimes led to confusion. Oral health information acquisition from antenatal institutions and care providers was rare. Greater attention was paid to dental visit when they obtained proper information from previous dental visit experience or family members. A potential strategy to improve oral health care suggested by the interviewees is to develop a health care system strengthened by inter-professional (antenatal-dental) collaboration. Efficient oral health information delivery, convenient access to dental service, and improved ‘quality’ of dental care targeting the needs of pregnant women were identified as possible approaches to improve dental care for this population. Conclusion: Dental care-seeking behaviour during pregnancy was altered by various internal and external factors. A lack of, or conflict between, information sources result in confusion that can restrict utilisation of dental service. Integrating dental care into antenatal service would be a viable way to improve dental service utilisation.

Abstract:
Objectives Dental caries is the most common preventable childhood condition. Non-dental professionals and health workers are often well placed to support parents in adopting positive oral health behaviours for their children. The aim of this study was to determine the effectiveness of behaviour change interventions and their individual component behaviour change techniques (BCTs), that were delivered by non-dental professionals and health workers. Methods A systematic search of Ovid MEDLINE, PubMed, CINAHL, Cochrane Library, Web of Science, TRoPHI and PROQUEST from inception until March 2021 was conducted. Randomised controlled trials and quasi-experimental studies for improving oral health outcomes in children were included. Quality assessment was carried out using Cochrane Risk of Bias tool and ROBINS-I tool. Publication bias was assessed using funnel plots and Egger’s regression intercept. Effect sizes were estimated as standardised mean difference (SMD) and odds ratio/risk ratio for proportions. Meta-analyses were performed for studies reporting mean decayed, missing, filled surfaces (dmfs) and mean decayed, missing, filled, teeth (dmft) indices. Behaviour change technique coding was performed using behaviour change technique taxonomy v1 (BCTTv1). Results Out of the 9,101 records retrieved, 36 studies were included with 28 showing a significant effect either in clinical and/or behavioural/knowledge outcomes. Most studies (n = 21) were of poor methodological quality. The pooled SMD for caries experience showed statistically significant result for caries prevention at surface level -0.15 (95% CI -0.25, -0.04) and at the tooth level -0.24 (95% CI -0.42, -0.07). In 28 effective interventions, 27 individual BCTs were identified and the most frequently used were: “Instructions on how to perform the behaviour” and “Information about health consequences”. Conclusion There is low quality of evidence suggesting non-dental professionals and health workers may help improve oral health outcomes for children. To confirm these findings, further high-quality studies incorporating a variety of BCTs in their interventions for adoption of good oral health behaviours are needed.

Abstract:
The purpose of this study was to explore the experience of parents whose young children had had a general anesthetic (GA) for dental treatment and to develop a model to describe and explain parental behaviour change following the GA experience. A grounded theory method was undertaken to investigate 1) parent's beliefs and behaviours that may place their child at risk to new caries following the GA experience, 2) parents' experience of their child's dental treatment under GA and 3) the factors affecting parental adoption and maintenance of dentally healthy behaviours. Twenty-six in-depth individual interviews were conducted with parents of pre-school aged children at various times after the GA, i.e. shortly after the GA and up to one year following the GA. Data were analysed with a grounded theory approach, to develop a model that was "grounded" in the data. A conceptual model was generated to explain the process of parental behaviour change. Social influences, family context, and parental strategies were identified as key categories. Cultural beliefs, actions of dental professionals, and media/advertising were barriers for parents to adopt healthy behaviours. Not all parents were receptive to social supports; cross-cultural differences were apparent. Overall, the GA dental experience had enough of an impact to immediately motivate parents to consider changing their behaviours. However, difficulty and only partial compliance in following recommendations were frequently mentioned. Although parental stretiges were influenceed by family context and social influences, the central position of parental strateiges in the model gradually emerged. Parents who took responsibility for their child's state of health felt guilt and were determined to develop strategies to overcome the barriers in applying healthy behaviours. Parents who had a high level of self-efficacy and were furthest along the stages of change continuum were likely able to engage in and maintain new healthy behaviours. Although an early, positive outcome of the GA was a reported improvement in dental health practices, the GA did not appear to affect long-term preventive behaviours for many parents. Parental strategies were recognized as the core category of the final model that influenced whether parents adopted dentally-healthy behaviours and maintained these behaviours over time.

Abstract:
Introduction: Oral diseases such as dental caries and periodontal diseases are among the most common diseases in Hong Kong. Family as a basic societal unit has an important role to play in shaping the individual member’s behaviours and health status. However, most dental research studies focus on modifiable risk factors of individuals rather than those of a family. Objectives: 1. to describe the oral health behaviours and oral health status of family members in a selected sample of families in Hong Kong; 2. to assess the relationships between oral health behaviours and oral health status amongst the family members; 3. to assess the influence of socio-economic factors, lifestyle factors and oral health knowledge, attitudes, and behavioural factors on oral health status of the spouses; and 4. to assess the influence of parental factors on the child’s oral health behaviours and status. Methods: A cross-sectional survey using a combination of a random household and a purposive sampling was conducted. The study population was 5 to 7-year-old children and their parents in Hong Kong. A clinical examination and a questionnaire survey were conducted on the core family members (parents and children) of the recruited families. Structural Equation Modeling (SEM) was employed to test the hypothesized multivariate models which tried to investigate the complex relationships among different risk factors and oral health status. Results: A total of 432 families with targeted children, 373 fathers and 424 mothers were recruited. The mean DMFT/dmft score of the father, the mother, and their children were 7.2, 6.2, and 2.6, respectively. Around half (52%) of the fathers and one-third (35%) of the mothers had periodontal probing pocket(s) deeper than 3mm. In the structural equation models, strong positive correlations were found between the oral health behaviours of fathers and mothers (∅=0.98, p<0.05), mothers and children (∅=0.79, p<0.05), and fathers and children (∅=0.74, p<0.05). Positive correlations were also found between the oral health status of fathers and mothers (∅=0.43, p<0.05), mothers and children (∅=0.33, p<0.05), and fathers and children (∅=0.30, p<0.05). Fathers’ oral health status was directly affected by their oral health behaviours and smoking habit, and indirectly affected by their socio-economic status and oral health knowledge and attitudes. The explained variance of fathers’ oral health status was 47%. The mothers’ oral health status was only directly affected by their oral health behaviours and indirectly by their socio-economic status and oral health knowledge and attitudes. The explained variance of mothers’ oral health status was 53%. Children’s oral health status was only directly affected by their oral health behaviours and indirectly by their mother’s socio-economic status, mother’s oral health knowledge and attitudes, and mother’s oral health behaviours. The explained variance of children’s oral health status was 26%. Conclusion: Oral health behaviours and status are correlated among family members. Children’s oral health status is affected by their oral health behaviours, which may be affected by parents’ socio-economic status, oral health knowledge, attitudes, and behaviours.

Abstract:
Background: Traumatic dental injuries (TDIs) are one of the most common body injuries and constitute an important public health problem. These injuries are considerably more common among adolescents, and can lead to pain, physical impairment, emotional distress and negative impact on the quality of life. Theories link most types of injuries to individual behaviours within a complex matrix involving both the physical and social environments. However, most of the aetiological studies on TDIs focus on proximal risk factors and overlook the underlying more distal determinants. This PhD thesis aimed to assess whether certain behavioural and psychosocial determinants were associated with the prevalence of TDIs among adolescents in Riyadh, Saudi Arabia, with a particular focus on the role of their risk-taking behaviours and peer influence. Methods: A stratified two-stage cluster sample of 902 students (461 boys and 441 girls) was randomly selected from adolescents attending 1st and 2nd years of public and private secondary schools in Riyadh, using a self-weighting design for both sexes and school types. Data were collected through clinical examination and questionnaire. TDIs were clinically diagnosed using a modified version of the WHO classification for epidemiological studies. The clinical examination also included assessment of overjet and lip coverage. The questionnaire was based on the WHO Health Behaviour in School-Aged Children questionnaire and the CDC Youth Risk Behaviour Surveillance System, assessing exposures risk-taking behaviours and peer influence, as well as demographics, socio-economic status and physical activity. The differences in prevalence of TDIs between the different groups of the covariates and exposures were calculated. Then, Poisson regressions with a robust error variance were used to estimate adjusted prevalence ratios (relative risks) of TDIs between the different exposures to provide sequential adjustment for confounding factors. The models were further checked for interactions between the main exposure and the peer influence variables. Results: Overall, 42.6% of adolescents had TDIs to their anterior teeth (Boys: 59.4%; Girls: 24.9%). After adjusting for age, sex, father’s education, nationality, physical activity and overjet >3mm, smoking was significantly associated with TDIs among girls (RR 2.50; 95% CI 1.42–4.41), and the same was the case among boys for fights (RR 1.46; 95% CI 1.19–1.79), for spending time with friends after school on more than three days a week (RR 1.25; 95% CI 1.07–1.46) and for having peers who carried weapons (RR 1.19; 95% CI 1.01–1.40), compared to their counterparts. TDIs were also significantly associated with both boys and girls who carried weapons (RR 1.36; 95% CI 1.12–1.66), had multiple risk-taking behaviours (RR 1.44; 95% CI 1.20–1.72) and had less than three close friends (RR 1.19; 95% CI 1.00–1.42) compared to their counterparts. The risk of TDIs was intensified among adolescents who carried weapons and had multiple risk-taking behaviours when they lacked peer support (RR 2.18; 95% CI 1.05–4.57 and RR 2.18; 95% CI 1.05–4.57, respectively) compared to their counterparts who had supportive peers (RR 1.28; 95% CI 1.01–1.62 and RR 1.36; 95% CI 1.11–1.68, respectively). Conclusions: Adolescents in Riyadh, particularly boys, had a very high prevalence of TDIs. Risk-taking behaviours (smoking, fights and carrying weapons) and negative peer influence (having peers who carried weapons) indicated an increased risk of TDIs among those adolescents independent of their age, socioeconomic status, physical activity and incisor overjet level. Negative peer influence (lack of peer support) intensified the association between risk-taking behaviours and TDIs.

Abstract:
Abstract General anaesthesia (GA) is a widely used sedation method in dentistry. It is usually used for patients with an extensive dental treatment need, most often related to dental caries, and limited coping skills to consider conventional dental care. These patients are often small children or persons with dental fear. Using dental general anaesthesia (DGA) is expensive, special equipment and trained staff are needed, and it is not without risks for patients. The aim of this study was to investigate factors associated with children’s DGA. In addition to dental caries and dental fear, general health status, oral health behaviours, family-related factors, as well as dental attendance after DGA were in focus. The thesis is composed of five independent studies. There were three different study populations ‒ one in specialised and two in primary health care. There was also an age- and gender-matched comparison group for one of the study populations. Questionnaires were used in three of the studies, and two of the studies were based on patient files. According to the results, DGA is more common among medically compromised children than among healthy children. Medically compromised children have more often a history of DGA treatments compared with their healthy peers. Dental caries and dental fear were the main reasons for DGA in all of the studies. Dietary and drinking habits, as well as oral hygiene behaviours were distinctly poorer among children undergoing DGA than among those treated in a normal dental setting. A history of DGA in the family, a large number of siblings and male gender were important background factors associated with DGA. Patients treated under DGA were prone to miss or cancel their upcoming appointments. In conclusion, DGA is necessary in some cases, but it could be avoided if factors associated with DGA were taken into account in treatment plans. DGA in itself does not have an enhancing effect on oral health over the long term
Tiivistelmä Yleisanestesia on hammashoidossa yleisesti käytetty sedaatiomenetelmä vaikeahoitoisille potilaille. He ovat usein pieniä lapsia, hammashoitopelkoisia tai sellaisia potilaita, joiden hoidontarve on liian laaja ja haastava tavanomaiseen hammashoitoon. Tämän tutkimuksen tavoitteena oli selvittää lasten nukutushammashoitoon liittyviä tekijöitä. Karieksen ja hammashoitopelon lisäksi tutkimuksen kohteena oli yleisterveydellisiä seikkoja, suunterveystottumuksia, perheeseen liittyviä tekijöitä sekä hammashoitopalvelujen käyttö nukutushammashoidon jälkeen. Tämä väitöskirja koostuu viidestä erillisestä osajulkaisusta. Tutkimusjoukkoja oli kolme: yksi erikoissairaanhoidosta ja kaksi perusterveydenhuollosta. Yhdelle tutkimusjoukolle oli ikä- ja sukupuolivakioitu vertailuryhmä. Kyselylomakkeita käytettiin kolmessa osajulkaisussa ja kaksi osajulkaisua perustui potilaspapereihin. Nukutushammashoito oli yleisempää yleissairailla kuin terveillä lapsilla. Yleissairailla lapsilla oli myös useammin nukutushammashoitohistoriaa kuin terveillä lapsilla. Karies ja hammashoitopelko olivat pääsyyt nukutushammashoitoon kaikissa tutkimuksissa. Juoma- ja ruokatottumukset, kuten myös suuterveystottumukset, olivat selkeästi huonommat nukutushammashoidossa hoidetuilla lapsilla kuin niillä lapsilla, jotka hoidettiin normaalisti hereillä. Perheen nukutushammashoitohistoria, suuri määrä sisaruksia ja miessukupuoli olivat merkittäviä nukutushammashoitoon yhteydessä olevia tekijöitä. Nukutushammashoidossa hoidetut potilaat jättivät usein tulematta nukutushammashoidon jälkeisille hammashoitokäynneilleen tai peruivat aikansa. Nukutushammashoito on välttämätön tietyissä tilanteissa, mutta se voitaisiin välttää, jos siihen liittyviä tekijöitä huomioitaisiin paremmin hoitosuunnitelmissa. Nukutushammashoidolla sinänsä ei ole suunterveyttä parantavaa pitkäaikaisvaikutusta

Abstract:
Objectives: Parental incarceration is an Adverse Childhood Experience (ACE) that can have a negative effect on health related Quality of Life (QOL) outcomes in adulthood. It is unclear how this ACE influences oral health in childhood and in adulthood. This study explores: 1. The oral-health and dental care experiences of men and women whose parents were incarcerated during their childhood; 2. How this childhood experience influences current behaviours and perceptions of oral health and dental care in adulthood. Methods: Semi-structured, in-depth interviews were conducted with adults who had one or both parents incarcerated during their childhood. The transcripts were analyzed using Interpretive Phenomenology to identify and describe dominant themes. Results: The eight participants in this study (four males, four females) were found to have experienced more than one ACE. Four themes emerged: 1) Instability; 2) Poverty, stigma and shame; 3) Past dental experiences, and 4) Value of empathetic dental professionals. Conclusion: This study aimed to provide awareness into the concepts that exist about oral health and dental care in adults that have experienced parental incarceration. We found that participants were able to receive dental care on a regular basis during childhood, (urgent and general dental care) however, preventive dental care at home was lacking. The manner in which dental care was delivered in childhood had a strong influence on dental behaviours in adulthood. Financial barriers such as inability to afford dental-care and non-financial barriers such as dental fear, stigma and shame exist for the participants in adulthood in accessing dental care. Perceived poor dental aesthetics made participants feel low self-esteem and social isolation, and restricted their career options. Oral health of their children is given more priority than their own and dental professionals who are empathetic are preferred. The findings of this study highlight that, similar to other vulnerable groups, it is important for dental practitioners to understand and practise Trauma Informed Care universally when working with children, in particular those who may have suffered from ACE, in order to provide experiences that promote their future oral-health.

Magister Scientiae Dentium - MSc(Dent)
A good oral health self-perception can contribute to improved knowledge of oral health self-care and practice as well as increase the proper use of dental care services. This study evaluated how adolescents from urban and peri-urban Maputo City assess their oral health status, behaviour and oral health risk factors. This is an analytic cross-sectional study, conducted in the urban and peri-urban schools of Maputo City involving adolescents in the age groups of 12 and 15-19 years old. The study was carried out in five schools, three Complete Primary schools and two Secondary schools from urban and peri-urban areas in Maputo City selected by convenience due to their geographic location. The size of the sample was 500 comprising 236 twelve year olds and 264 15-19 year olds. Data was collected using a self-completion questionnaire designed by the World Health Organization (WHO) and translated into Portuguese. The questionnaire included variables such as socio-demographic data (age, gender, location and parent or guardian level of education), self-assessment of oral health status and quality of life; self reported oral health behaviour and lifestyles, oral health risk factor knowledge (alcohol, tobacco and dietary), dental visits and daily impact of oral health. Chi-square for associations and a Spearman correlation tests were used to determine relationships between categorical data. All tests were assumed statistically significant at p≤0.05. The results showed that most of the adolescents classified their teeth (49.7%) and gum (38.2%) health as normal. There was no statistical difference between adolescents from urban and peri-urban schools (Spearman rs (399) = 0,114, p =0,02). The majority (n=322; 65.2%) of the adolescents clean their teeth twice a day. There was no difference between school level (primary and secondary school) and frequency of teeth cleaning. Most of the adolescents use a toothbrush (97.8%) and toothpaste (93.5%) to clean their teeth and only 11.9% also use dental floss but 52.1% didn´t know if their toothpaste was fluoridated or not. Smoking was reported by less than 1% of the adolescents. The main reason for dental service utilization, (reported by 67.5%) was pain or problems with teeth, gums or mouth. There was an association between oral health status and problems experienced in daily life because of their teeth and mouth. There was no significant difference for oral health assessment, risk factors and behaviours, between adolescents from urban and peri-urban schools. Although some satisfactory results were found, the need to strengthen oral health promotion in schools is high, especially considering the causes for dental service utilization were mostly pain and trouble with teeth in this group.

Abstract:
Dental restorative materials including amalgam, dental ceramic, gold alloy, dental resin, zirconia, and titanium alloy are used to reconstruct damaged teeth, as well as to recover their function. In this study, the mechanical properties of various dental restorative materials were determined using test specimens of identical shape and dimension under the same three-point bending test condition, and the test results were compared to enamel and dentin. The maximum bending force of enamel and dentin was 6.9 ± 2.1 N and 39.7 ± 8.3 N, and the maximum bending deflection was 0.12 ± 0.02 mm and 0.25 ± 0.03 mm, respectively. The maximum bending force of amalgam, dental ceramic, gold alloy, dental resin, zirconia, and titanium alloy were 1.9 ± 0.4 N, 2.7 ± 0.6 N, 66.9 ± 4.1 N, 2.7 ± 0.3 N, 19.0 ± 2.0 N, and 121.3 ± 6.8 N, respectively, and the maximum bending deflection was 0.20 ± 0.08 mm, 0.28 ± 0.07 mm, 2.53 ± 0.12 mm, 0.37 ± 0.05 mm, 0.39 ± 0.05 m, and 2.80 ± 0.08 mm, respectively. The dental restorative materials that possessed greater maximum bending force than that of enamel were gold alloy, zirconia, and titanium alloy. Gold alloy and titanium alloy had greater maximum bending force than dentin. The dental restorative materials that possessed greater maximum bending deflection than that of enamel were all of the dental restorative materials, and the dental restorative materials that possessed greater maximum bending deflection than that of dentin were all of the dental restorative materials except amalgam. The appropriate dental restorative materials for enamel are gold alloy and zirconia and for dentin is gold alloy concerning the maximum bending force and the maximum bending deflection. These results are expected to aid dentists in their choice of better clinical treatment and to contribute to the development of dental restorative materials that possess properties that are most similar to the mechanical properties of dental hard tissue.

Abstract:
A theoretical model was developed to describe the structural behavior of indented pipe under pressure. The model suggested that the transverse shape of the dent, which can be characterized by a single easily-measured parameter, significantly affects rerounding behavior. The model gave predictions for rerounding that were in good agreement with results of tests. Tests also indicated that dent rerounding behavior is cycle-dependent. The model sets a groundwork for estimating the fatigue life of dented pipe subject to pressure cycles. The results apply primarily to plain dents, but might be adapted to those that contain collateral mechanical damage.

Abstract:
This work is within an ongoing study, which aims to propose a new methodology for fatigue life analysis of steel pipelines with plain dents under cyclic internal pressure. This methodology follows the current high cycle fatigue theory and employs stress concentration factors induced by plain dents to modify standard S-N curves. A previously developed and validated finite element model is extended to generate stress concentration factors for longitudinal and transverse dents, in addition to spherical dents. Several finite element analyses are carried out in a parametric study to evaluate stress concentration factors induced by the three dent types studied: spherical, longitudinal and transverse dents. Analytical expressions are developed to estimate stress concentration factors for these three dent types as function of pipe and dent geometric parameters. Small-scale fatigue tests are conducted to evaluate the finite life behavior of dented steel pipes under cyclic internal pressure. The methodology is validated in view of the fatigue tests results. Including expressions to estimate stress concentration factors for three different dent types (spherical, longitudinal and transverse dents), the proposed methodology can then be used for fatigue life analysis of dented steel pipelines under cyclic internal pressure.

Abstract:
The objective of this study was to investigate the effect of the dent magnitude on the collapse behavior of dented pipe subjected to a combined internal pressure and in-plane bending. The plastic collapse behavior and bending moment of the dented pipe with several of dent dimensions were evaluated by using elastic–plastic finite element (FE) analyses. The indenters used to manufacture the dents on the API 5L X65 pipe were hemispherical rod type with diameter of 40, 80, 160 and 320 mm. Dent depths of 19, 38, 76, 114 and 152 mm were introduced on the pipe having a diameter of 762 mm and a wall thickness of 17.5 mm in analyses. A closing or opening inplane bending moment was applied on the dented pipes pressurized under internal pressure of the atmospheric pressure, 4, 8 and 16 MPa. The FE analyses results showed that the plastic collapse behavior of dented pipes was considerably governed by the bending mode and the dent geometry. Moment-bending angle curves for dented pipe were obtained from computer simulation and evaluated with a variety of factors in FE analyses. Load carrying capacity of dented pipes under combined load was evaluated by TES (Twice Elastic Slope) moments. Load carrying capacity of pipe having up to 5% dent depth of outer diameter was not reduced compared with that of plain pipe. Opening bending mode had a higher load carrying capacity than closing bending mode under combined load regardless of dent depth. TES moment was decreased with increasing the dent depth and internal pressure regardless of bending modes.

Abstract:
Abstract Pipeline dents can be developed from the pipe resting on rock, a third-party machinery strike, rock strikes during backfilling, amongst other causes. The long-term integrity of a dented pipeline segment is a complex function of a variety of parameters including pipe geometry, indenter shape, dent depth, indenter support, secondary features, and pipeline operating pressure history at and following indentation. In order to estimate the safe remaining operating life of a dented pipeline, all of these factors must be considered and guidelines for this assessment are not available. US DOT regulations (49 CFR 192 and 195) include dent repair and remediation criteria broadly based upon dent depth, dent location (top or bottom side), pressure cycling (liquid or gas), and dent interaction with secondary features (weld, corrosion, cracks). The criteria defined above are simple to use, however, they may not direct maintenance to higher risk dent features and be overly conservative or, in some cases, unconservative. PRCI, USDOT, CEPA and other full-scale testing, finite element modelling and engineering model development research has been completed to evaluate the integrity of pipeline dents. These results have demonstrated trends and limits in dent behavior and life that can improve on existing codified and traditional treatment of dents. With these research results a guideline for dent management can be developed to support operators develop and implement their pipeline integrity management programs. This paper provides an overview of the newly developed API recommended practice for assessment and management of dents (RP 1183). The RP considers dent formation strain, failure pressure and fatigue limit states including the effects of coincident features (i.e. welds, corrosion, cracks and gouges). This paper will focus on how pipeline operators can derive value from this step change in integrity management for dents. The paper describes the basis for the dent screening and integrity assessment tools included in the RP. This RP provides well founded techniques for engineering assessment that may be used to determine the significance of dent features, if remedial actions are required and when these actions should be taken.

Full text
Abstract:
Dent length has been shown to have a significant effect on the fatigue cracking behavior of pipeline dents. Long dents, which experience rerounding and center cracking, have a dramatically shorter fatigue life than otherwise similar short dents, which experience peripheral cracking and little rerounding. Because the fatigue lives of long dents are much shorter than those of short dents, both safety and economy would benefit from improvements in the ability to distinguish long dents from short dents. Based on experimental evidence, a transition between short and long dent behavior is shown to exist. Finite element models are used to further explore the nature of this transition by allowing the examination of cases not available in the experimental record and by permitting stress behavior to be studied. A parametric study is used to quantify the nature of the short dent to long dent transition for a range of cases. Relative dent lengths that bound short and long dent regions of behavior are proposed for these cases.

This study utilizes novel characterization techniques nanoindentation and nanoscratch for testing both the human enamel and dentine together with two biocompatible dental filling materials; epoxy nanocomposite and silver amalgam. Nanoindentation tests were performed to obtain accurate hardness and reduced modulus values for the enamel, dentin and two different fillers. We utilized Nano-scratch tests to obtain critical load in scratch test and resistance to sliding wear. Testing showed the silver amalgam filling has a higher modulus of elasticity, hardness and wear resistance compared to the nanocomposite. The novel mechanical characterization techniques utilized might assist in better understanding the mechanical behavior of the dental fillers and thus facilitate the design of robust fillers with excellent mechanical properties.

Full text
Abstract:
Pipeline dents lead to changes in the stress/strain state of the pipe body, making it more susceptible to integrity concerns. This susceptibility is especially prevalent in cases where additional stress risers such as crack and/or corrosion features interact with the dented region. While some guidance is available in codes, regulations, and industry best practices, there is substantial room for innovation and improvement to ensure pipeline safety. Existing explicit models are primarily based on experimental correlations and historical findings using simple parameters such as dent depth and location on the pipeline. Moreover, these models are subjected to a substantial uncertainty in both accuracy and precision. This paper presents a state-of-the-art methodology for analyzing dents and dents associated with stress risers through the use of finite element method (FEM) as a mechanical model and reliability analysis to address uncertainties associated with input variables. FEM is used to model the full geometry of dents and any interacting stress risers reported by inline inspection (ILI) to be incorporated into calculations of the internal stresses/strains within the feature. Theoretically, FEM and reliability analysis can be integrated through reliability-based stochastic finite element methodologies due to the absence of closed form mechanical models of dented pipes. However, these methodologies are computationally prohibitive and not suited/designed for frequent integrity analysis. This study aims at further advancing such integration by combining FEM with reliability science to account for pipe properties and measurement uncertainties in order to determine the probability of failure under different operating conditions using surrogate models. This provides the opportunity to more accurately assess the risk posed by ILI reported dent features. Herein, surrogate models refer to the response surface method (RSM) which is considered as a valuable tool for obtaining insight into the behavior of structural random systems at low computational costs. The proposed approach was applied focusing on a plain dent, a dent interacting with a corrosion feature, and a dent interacting with a crack feature. First Order Reliability Method (FORM) is used to evaluate the probability of failure/reliability using the resulting RSM non-linear limit states for each dent feature.

Abstract:
This work presents a numerical-experimental methodology to study the fatigue behavior of dented pipes under internal pressure. A full-scale experimental program on dented pipes containing gouges were achieved. Two types of defects were studied: metal loss (plain dent) and sharp notch. Both defects acting independently reduce the fatigue life performance but their combination is highly detrimental and must be avoided. We did not find a severity threshold (e.g. dent depth or crack depth) where these defects could coexist. In addition, based on numerical analyses we proposed a new expression for stress concentration factor (SCF) in line with transversal indentation. This information was successfully integrated into a simple fatigue model where the fatigue life predictions were practically inside the window of experimental results.

Abstract:
Research conducted in many countries has highlighted the vulnerability of men who have sex with men (MSM) to HIV and other STIs. Yet in Africa, they receive little attention in HIV/AIDS programming and service delivery because of widespread denial and stigmatization of homosexual behavior. In Senegal, a study conducted by researchers from the National AIDS Control Program, Cheikh Anta Diop University, and the Horizons Program has provided valuable information about the needs, behaviors, knowledge, and attitudes of MSM that has important implications for program managers and policymakers working to stem the spread of HIV/AIDS. The researchers used ethnographic and survey methods to elicit information from MSM 18 years of age or older from several neighborhoods in Dakar. As noted in this brief, the research team examined their own preconceived notions about sexuality, working through prejudices and taboos, and stressing the importance of maintaining the confidentiality of informants. All interviews were anonymous and informants were asked to provide oral informed consent. Informants received a small stipend to cover travel costs, information on STIs and HIV/AIDS, and a referral for a free medical consultation and treatment.
