Incipient caries lesions or white spot lesions are one of the most common clinical problems resulting from orthodontic treatment with fixed appliances. Literature has shown that infrared photothermal radiometry and modulated luminescence (PTR-LUM), used by The Canary System for caries detection, is capable of monitoring artificially created carious lesions and their evolution during demineralization. Recently, a water-based calcium aluminate glass ionomer luting cement, Ceramir, has shown bioactive surface apatite formation that may influence local remineralization. This in vitro study’s objective was to evaluate effects of bioactive cement on enamel demineralization around orthodontic brackets compared to composite resin cement. A sample of 32 caries-free extracted human teeth was collected under an IRB-exempt protocol. Orthodontic brackets were cemented to each tooth with either Transbond XT or Ceramir. A 3x3 mm window adjacent to the bracket was created with acid-resistant varnish f

Abstract: Objective: Evaluate the action of nanoparticulate adhesive with fluoride release capacity in the prevention of white spot lesions (WSL) in patients under orthodontic treatment. Materials and methods: In 37 individuals undergoing orthodontic treatment, a conventional orthodontic adhesive (Transbond XT) and a nanoparticulate adhesive with the ability to release fluoride (Opal Seal) were applied in a split mouth design. Before bonding and at the end of treatment, patients were submitted to clinical examination and intraoral photographs. During the evaluation period, monthly assessments of the amount of adhesive present were also performed, as seen by UV-A light. To compare the adhesives, we used multifactorial ANOVA, with score at the end of treatment as dependent variable. In the study of the concordance between the evaluation methods, the ordinal Spearman correlation coefficient and the Bland-Altman concordance analysis were performed. For the remain time of the Opal Seal adhesive, a survival curve was used, and in the comparison of the debonding index, the survival curve and the Kaplan-Meier survival analysis were also used. Results: There was no difference between the tested adhesives, whatever the evaluation method used, so that the formation of WSL does not differ between the adhesives (p= 0.581). There was no tooth that was more affected by WSL in relation to the other teeth evaluated (p= 0.861). There was no difference between the methods of evaluation (P = 0,581) and th...

A desmineralização do esmalte dentário durante o tratamento ortodôntico é, ainda, um problema significante na Ortodontia. A presença de um aparato metálico retentivo sobre uma superfície dentária plana permite um sítio ideal para retenção de bactérias e restos alimentares, dificultando a higienização. O presente trabalho teve como objetivo avaliar através da lupa estereoscópica e da microscopia eletrônica de varredura, o efeito de um adesivo ortodôntico e um selante de fóssulas e fissuras na prevenção da desmineralização do esmalte ao redor dos bráquetes ortodônticos após exposição dos dentes à solução desmineralizadora. Foram utilizados 90 incisivos bovinos separados em três grupos de 30 dentes cada: grupo adesivo (G1), grupo selante de fóssulas (G2) e grupo controle (G3). Após a colagem dos bráquetes, os dentes foram submetidos a uma solução desmineralizadora durante 14 dias com monitoramento do pH através de um peagômetro. A análise por lupa estereoscópica e microscopia eletrônica de varredura mostrou que em todos os 90 dentes foram observados a ocorrência de desmineralização ao redor do bráquete ortodôntico. Entretanto, as áreas de perda de esmalte foram diferentes nos três grupos (ANOVA, p < 0,001). O grupo G2 apresentou uma redução significativa na incidência de desmineralização do esmalte (71,9%), enquanto esta redução no grupo G1 foi de 38%, quando comparados com grupo G3 (Tukey, p < 0,001). À microscopia eletrônica de varredura pode-se verificar a presença de crateras, poros e perda da camada aprismática do esmalte nos três grupos. O uso de selantes de fóssulas e fissuras para proteção da superfície vestibular dos dentes reduziu significativamente a desmineralização do esmalte in vitro.
The demineralization of dental enamel during orthodontic treatment is still a significant problem in Orthodontics. The presence of a retentive metallic apparatus on a dental flat surface allows an ideal site for retention of bacteria and food debris, making the cleaning difficult. This study aimed to evaluate through the stereoscopic microscope and scanning electron microscopy, the effect of an orthodontic adhesive and pit and fissure sealant preventing demineralization of enamel around orthodontic brackets after exposure of the teeth to demineralized solution. Ninety bovine incisors were used in three separate groups of 30 teeth each: adhesive group (G1), sealant of fossulae group (G2) and control group (G3). After bonding of brackets, the teeth were demineralized in a solution during 14 days with pH monitoring by a pH Meter. The analysis by stereoscopic microscope and scanning electron microscopy showed that in all 90 teeth was observed the occurrence of demineralization around orthodontic brackets. However, the areas of loss of enamel were different in the three groups (ANOVA, p < 0,001). The G2 group showed a significant reduction in the incidence of demineralization of enamel (71,9%), while the reduction in G1 was 38% when compared with group G3 (Tukey, p < 0,001). Scanning electron microscopy verified the presence of craters, pores and loss of the enamel aprismatic layer in the three groups. The use of pit and fissure sealant for protecting the labial surface of the teeth resulted in a significantly reduction of enamel demineralization in vitro.

Повний текст джерелаINTRODUCTION The initial carious lesions (white spots) indicate an area of demineralization of enamel as a result of an inadequate hygiene-dietary regime. The prevention of white spots lesions (WSL) is necessary in order to obtain the maximum effect of the therapy with fixed orthodontic appliances. In the prevention and treatment of white spots, products based on casein-phosphopeptide-amorphous calcium phosphate (CPP-ACP) are applied as well as preparations based on fluoride. The aims of the study were to examine the presence of initial carious lesions on the surface of the tooth after treatment with fixed orthodontic appliances and to assess the success of the therapy of initial caries lesions. MATERIAL AND METHODS The study included 100 patients aged 15-50 who were treated with fixed orthodontic appliances, at the public Dentistry Clinic of Vojvodina. Patients were divided into two groups: experimental (patients who used Tooth Mousse paste and standard oral hygiene products) and control group (using only standard oral hygiene products). The photos of patients were made and analyzed in three stages of the study - before the beginning of the treatment, after the removal of fixed orthodontic appliances and after the therapy of initial caries lesions. Using the "Onyxceph" software program, the database was created, which was used for the purposes of this research. The questionnaire composed mostly of close-ended questions was used for the purpose of this survey. RESULTS The restates of this study indicated that a majority of respondents were female. (68%). The initial carious lesions were more commonly diagnosed in men. The majority of patients with WSL were in group of young adult people (42%) and adolescents (32%). In 73% of all patients who were treated with fixed orthodontic appliances, were diagnosed WSL on the end of the orthodontic treatment. Patients who consumed confectionery products several times during the day, during the orthodontic treatment, had the highest percentage of white spots lesions (87.5%). CONCLUSION Both hypotheses have been confirmed: 1.The prevalence of initial carious lesions of the tooth enamel after fixed orthodontic therapy was higher than 60% in patients who had fixed orthodontic appliances for at least a year. 2. White spot therapy with Tooth Mousse's products showed significantly better results compared to a group of subjects who only used standard oral hygiene products. On the basis of the obtained results of clinical trials, it can be concluded that the prevalence of initial caries lesions is proportionally greater in patients with lower oral hygiene during orthodontic treatment, compared to patients who had higher awareness of the importance of the hygiene-dietary regime. The use and application of Tooth Mousse paste in the treatment of initial carious lesion is vital for the re-mineralization of the enamel surface.

Повний текст джерелаWhite Spot Lesions (WSLs) are a common iatrogenic finding along brackets used in orthodontic treatment. WSLs are frequently noticed as small opaque lesions with lessened radiolucency which might have a lasting unaesthetic effect. These lesions might range from small lines along bracket peripheries and less frequently might be observed as larger demineralized areas with or without cavitation. The development of WSLs is principally enhanced by the accumulated plaque around brackets due to a compromised oral hygiene that might be aggravated by the presence of dental crowding. Furthermore, The presence of fixed orthodontic apparatus leads to alteration in the oral microflora causing reduction in the PH level and increased bacterial adherence to the metal facade through electrostatic effect. There are several preferences for treatment of WSL, ranging from conservative approaches relying on remineralization to invasive techniques. The severity of lesions is a determinant of which option is most appropriate. The management of WSLs is based on remineralization strategies or in other situations on a minimal-invasive camouflage of the lesions. Although orthodontic WSLs are one of the most frequent and most visible adverse effects of comprehensive fixed appliance treatment, the efficacy of their intervention continues to be assessed in the literature and up to date there is no consensus on the best evidence-based approach to manage such lesions. Therefore, the aim of the present thesis is to review and critically appraise the contemporary evidence related to causes, diagnosis, prevention, risk evaluation and management of WSL associated with orthodontic appliances. Furthermore, clinical recommendations that might be useful for both the general dentist as well as the orthodontist. This literature review will be undertaken by searching the database engines, Pubmed, Medline, Google Scholar, B-on and Science Direct. The search will include the literature published inbetween 2005-2021.
