Abstract (sommario):

Background: immediate dentures are one of denture treatment that provides a rapid treatment stage to improve aesthetics without patients experiencing toothless phase due the tooth is extraction or decaputated. Purpose: To reported maxillary immediate partial denture and mandibulary immediate complete overdenture with magnetic retention to improve facial aesthetics. Case: A-56 years old woman with twelve tooth loss (17,16,15, 26,34,35,36,37,44,45,46,47) and have fillings teeth on 21,11 and 12 patched in dental artisans less more than 1 year and now its felt swollen with mobility 30 in the last few weeks and teeth 31,41,42,43 experienced mobilitys 20 due to calculus and teeth 32,33 were deep caries with mobility 30. Case Management: in phanoramic photo teeth 11,21 and 22 saw a large periapical lesion Ø 10mm and its advised to extract. In 32 and 33, non-immediate extraction was performed because periapical lesions and deep caries are large enough with the presence of periapical abscesses, while teeth 31, 41, 42 and 43 are scaling and rootplaning then endodontic treatment is performed to obtain a harmonious relationship between the upper anterior teeth and below the teeth 31,41.42.43 is immediately decaputated and restored with GI cement on the surface of the teeth and magnet keeper coping was done for 43. Discussion: The main objective of the immediate denture treatment is to avoid psychological, social and discomfort from look toothless Conclusion: Immediate denture is the choice of treatment to improve the retention and facial aesthetic.

Abstract (sommario):

Abstract The clinical management of mobile teeth can be a perplexing problem, especially if the underlying causes for that mobility have not been properly diagnosed. In some cases, mobile teeth are retained because patients decline multidisciplinary treatment that might otherwise include strategic extractions. This article discusses the relationship between occlusion and tooth mobility with an emphasis on identifying differences between increased mobility and increasing mobility. The indications, contraindications, and basic principles of tooth splinting are also reviewed. Provisional and definitive splints are defined and described with their respective occlusal considerations. Some mobile teeth can be treated through occlusal equilibration alone (primary occlusal trauma). Whereas mobile teeth with a compromised periodontium can be stabilized with the aid of provisional and/or definitive splinting (secondary occlusal trauma). It is important to consider splint therapy, because it may not only improve the prognosis of teeth, but may actually enhance the stability of the final prosthodontic treatment. The ultimate goal of successful management of mobile teeth is to restore function and comfort by establishing a stable occlusion that promotes tooth retention and the maintenance of periodontal health.

Abstract (sommario):

We describe a case of a 71-year-old otherwise healthy man who presented to the dental clinic with the chief complaint of mobility involving his upper left molar teeth. The patient was a febrile, and clinical oral examination revealed localised grade II mobility and absence of gingival swelling, erythema or sinus tract. Orthopantogram revealed a poorly defined radiolucency involving the upper left second and third molar teeth. Surgical exploration of the involved area was performed and revealed the presence of a ‘jelly like’ brown tissue that fragments easily. Pathological examination confirmed the diagnosis of diffuse large B cell lymphoma.

Abstract (sommario):

ABSTRACT The replacement of natural teeth that have extreme external apical root resorption, induced by orthodontic treatment, with osseointegrated implants is not justifiable biologically or clinically. These teeth should be preserved and keep their normal functions, as there is no greater mobility, pain or color change. They may undergo usual procedures, such as bleaching, restorations with veneers and other esthetic procedures that may be necessary along life. The pulp of these teeth is normal. If mobility of a tooth with extreme resorption is identified, the cause of mobility should be investigated, as it is not associated with resorption, not even at advanced stages. Tooth mobility may be associated with recent removal of orthodontic appliance, occlusal trauma, chronic inflammatory periodontal disease, or even severe cervical bone loss. In such cases, the cause of mobility should be eliminated and possible sequelae should be corrected, because these, and not root resorption, may actually require retention.

Abstract (sommario):

Patients with periodontal disease can lead to severe tooth mobility so often complains of pain when eating, decreased chewing ability and functional occlusion. Tooth mobility is a movement in a horizontal or vertical direction and one of the most unpleased effects from periodontal disease. Basically, tooth mobility is not a disease that requires treatment, but it is a symptom of periodontal tissue morphology changes, so it became a challenge for dentists in making decisions to maintain proper care of the teeth. Recent studies improved the use of periodontal splint with fiber reinforced composite (FRC) or fiber composite may lead to a long-term prognosis of teeth mobility due to periodontal disase. The case report describes treatment of chronic periodontitis patients with splinting fiber composites as a method for stabilization of the lower anterior teeth providing aesthetics, comfort, improved functionality occlusion, mastication and a good prognosis.

Abstract Objective: To determine the periodontal characteristics of diabetic patients with tooth mobility attending the Periodontology Clinic of University of Benin Teaching Hospital (UBTH), Benin City, Nigeria. Materials and Methods: This cross-sectional observational study was conducted among diabetic patients with tooth mobility in the Periodontology Clinic in UBTH, Benin City, Nigeria. The indices recorded for the participants were gingival index, community periodontal index of treatment need, and Miller'sindex for tooth mobility. Results: A total of 54 participants who met the inclusion criteria were approached, but only 49 of them consented and participated in this study giving a 90.7% recruitment rate. The age range and mean age of the participants were 42–84 years and 63.84 ± 1.31 years, respectively. The self-reported age of diagnosis was between 41 and 70 years with a mean age of 56.22 ± 6.88 years. About two-thirds (67.3%) of the participants were males. Less than half (38.8%) of patients were visiting the dentist for the first time. Mandibular arch housed about two-thirds (64.9%) of the mobile teeth and mandibular left quadrant housed about one-third of (34.5%) the mobile teeth. Central incisor (42.3%) constituted the most mobile teeth followed by the first molar (28.9%). A total of 17.0% of the mobile teeth were Miller's Grade 3 mobility. More than one-third (28.5%) (code 3 = 26.5%, code 4 = 2.0%) of the participants had periodontal pockets. More than half (52.7%) of participants had probing pocket depth of 5 mm and above. The gingival score which had mean as 1.60 ± 0.08 was significantly associated with age of the participants. The mean probing depth was 4.86 ± 0.21 mm. The probing depth was significant with age and duration of diabetes mellitus (DM) of the participants. Conclusion: Data from this study revealed that age of diagnosis of diabetes with tooth mobility was higher than previously reported. The most mobile teeth and earliest teeth to become mobile were the mandibular incisors, and Grade 1 severity constituted the majority. DM with tooth mobility exhibited gingival score and probing depth that had a variable significant association with demographic characteristics.

Abstract (sommario):

Humans have two sets of teeth, deciduous teeth and permanent teeth. When primary teeth fall out, permanent teeth erupt to maintain the chewing function and jaw development. Shedding occurs with increasing level of mobility in primary teeth as a result of root resorption. This report describes an uncommon clinical case that occurred in primary molars with internal resorption and pinkish discoloration. Pink tooth is worrisome for children and parents. Children should have their teeth examined on a regular basis to detect any problems in the process of tooth shedding and eruption.

Abstract (sommario):

Summary: Some 250 Australian aboriginal skulls were studied to ascertain differences in tooth dislocation and wear in this ethnic group as compared with those manifested in the pre-European Maori, with consideration of the differences in cultural and botanical background as contributing factors. Other features were studied, including the crowding of anterior teeth, the incidence of caries and abscesses, and of mottled enamel and tooth fracture. Aspects of physical anthropology and biology were found to be relevant to this study, since they offered explanations for some previously unsolved problems such as edge-to-edge bite, and crowding of incisors in well-formed jaws. The work is supported by 28 illustrations of the dentition selected from various sources, and described in the text. Reprints of 18 other published papers reporting various dental studies of relevance to the above major publication are included in this presentation.

Abstract (sommario):

Sandby borg, an Iron Age ringfort on Öland, Sweden has been and is still at the center of attention in media and archaeological research. The massacre uncovered at the site during recent years opens many doors for analyses on the Migration Period (c. 400-550 AD) Iron Age skeletal remains. Eighteen teeth (molars) from 12 individuals and three rodent teeth were chosen for strontium (87Sr/86Sr) analyses. This was done to establish whether these individuals were locals or non-locals to Öland. The analyses displayed a, for the most part, local 87Sr/86Sr ratio. Two non-locals were identified, as well as a pattern of higher 87Sr/86Sr peaks on numerous of the individuals during a certain age span, which could indicate a local weaning process with a special food.

Abstract (sommario):

This thesis deal with three individual Pagophilus groenlandicus canin teeth from the location Asva, Estonia dating from the Late Bronze Age (here 700-900 B.C). The aim of this thesis is to find out whether the three harp seal individual was local or non-local to Asva and further if they were migrants from the Atlantic Sea. The teeth enamel are analysed for strontium isotopes using LA-ICP-MS and the result was compared against the strontium 87Sr/86Sr values in various rivers in the Baltic Sea. This is to see how the harp seal has migrated around in the Baltic Sea. By placing the 87Sr/86Sr values against the rivers, it may seem that the three harp seals were non-local and not from the Atlantic Sea.

Abstract (sommario):

This study examined the impact of involuntary mobility on the academic achievement of tenth grade students in a Central Florida school district. Students of involuntary mobility were selected as the result of new attendance boundaries due to new high school construction. Students were compared against non-mobile peers at schools of like demographics (i.e. poverty level and ethnicity). Mobility status (involuntary or no mobility) was the independent variable. The dependent variable, academic achievement, was measured by students' tenth grade developmental scale scores in reading and mathematics on the Florida Comprehensive Assessment Test. Students' ninth grade test scores were used as a covariate to control for students’ prior achievement and isolate the impact of mobility. Additional subgroups (minority and poverty) were compared to determine if involuntary mobility had a more significant impact on these groups. Finally, a hierarchical linear regression was used to determine if a model for reading and mathematics could be used to predict future academic performance for students of involuntary mobility. Findings showed consistently there was no statistically significant difference in the achievement performance among groups or subgroups and the subject tests of reading and/or mathematics with one exception. There was a statistically significant difference in mathematics achievement in the all students group when comparing those students of involuntary mobility with students of stability. Students of mobility actually indicated a modest level of higher achievement than non-mobile peers. The hierarchical linear model was found to be marginally significant for predicting achievement among involuntary mobility students in the area of mathematics, but not necessarily in reading. Future research recommendations include broadening the research to additional grade-levels. This research only considered the impact of achievement on high school students. Future research should consider similar impact on students at both the elementary and/or middle school levels. Qualitative measures would provide additional information, particularly the perceptions and experiences that stakeholders have throughout the involuntary mobility process. Other at-risk subgroups, particularly those of residential mobility and/or previous retention, provide additional considerations that would add to this body of research. Finally, involuntary mobility as the result of school closings would provide additional insight as this factor often has public negative perceptions.

Abstract (sommario):

Yes
Establishing the age at which prehistoric individuals move away from their childhood residential location holds crucial information about the socio dynamics and mobility patterns in ancient societies. We present a novel combination of strontium isotope analyses performed on the over 3000 year old “Skrydstrup Woman” from Denmark, for whom we compiled a highly detailed month-scale model of her migration timeline. When combined with physical anthropological analyses this timeline can be related to the chronological age at which the residential location changed. We conducted a series of high-resolution strontium isotope analyses of hard and soft human tissues and combined these with anthropological investigations including CT-scanning and 3D visualizations. The Skrydstrup Woman lived during a pan-European period characterized by technical innovation and great social transformations stimulated by long-distance connections; consequently she represents an important part of both Danish and European prehistory. Our multidisciplinary study involves complementary biochemical, biomolecular and microscopy analyses of her scalp hair. Our results reveal that the Skrydstrup Woman was between 17–18 years old when she died, and that she moved from her place of origin -outside present day Denmark- to the Skrydstrup area in Denmark 47 to 42 months before she died. Hence, she was between 13 to 14 years old when she migrated to and resided in the area around Skrydstrup for the rest of her life. From an archaeological standpoint, this one-time and one-way movement of an elite female during the possible “age of marriageability” might suggest that she migrated with the aim of establishing an alliance between chiefdoms. Consequently, this detailed multidisciplinary investigation provides a novel tool to reconstruct high resolution chronology of individual mobility with the perspective of studying complex patterns of social and economic interaction in prehistory.

Abstract (sommario):

Tooth avulsion refers to total displacement of the tooth out of its alveolar socket. This chapter discusses the causes of avulsion for both primary and permanent dentition in addition to the prevalence of avulsion comparing it between before and during COVID-19 era. Successful outcomes depend on procedure conduction with immediate replantation of the avulsed tooth and good handling of the tooth keeping the tooth in suitable available storage media till a professional service is obtainable. Management of this type of dental trauma necessitates awareness and collaboration between the lay personal at the site of injury in addition to the important role of different dental professional. After replantation of the avulsed tooth, it should be kept immobile with preservation of the functional (physiological) mobility by application of suitable splint. There are adjunctive therapies including antibiotics, analgesics, mouth washes, and tetanus vaccines. Endodontic therapy should be initiated within 7–10 days from the time of avulsion, where the outcomes generally might be favorable or unfavorable. Newly emergent teledentistry played important role in the treatment of tooth avulsion, especially during COVID-19 period.

Abstract (sommario):

This chapter discusses human bones and teeth, which are the primary databank for biological anthropologists. The topic has aroused little interest among historians of antiquity. The beginnings of an explanation of this disparity are to be sought in the fact that human skeletal remains have no obvious relevance as a source of information for politics, political institutions, political thought, government, law, religion, warfare: in brief, for the traditional concerns of ancient historians. A second consideration is that biological anthropology is rooted in prehistory; its practitioners are characteristically involved in the exploration of the origins of humanity. Fortunately, some anthropologists have allowed themselves to stray into historical periods, including the classical world of Greece and Rome. In the meantime, historians of antiquity are showing increased interest in social, economic, and cultural history, and are displaying a new willingness to expose themselves to other disciplines, including the natural and social sciences. Thus, the time seems ripe for fruitful communication between historians and anthropologists. Specifically, health and demography (mortality, fertility, and mobility) hold promise as fields for constructive dialogue and collaborative research.

Testo completo

Abstract (sommario):

This chapter follows Zadie Smith’s “root canals,” a metaphor and a narrative form she developed in her first novel White Teeth (2000), to describe the transnational historical networks obscured by nation-centered accounts of the past. It argues that Smith develops modernist literary forms of unboundedness like the root canal in order to entwine different groups’ collective memories; she then uses that strategy to address head on the topic of causality within a global framework. Smith asks what economic, political, and personal conditions bring migrants to Europe and the United Kingdom and, in turn, how residents in metropolitan countries might be implicated in stories of migration, distant violence, and global economic inequality that they see as irrelevant to their everyday lives. Focusing specifically on Smith’s northwest London fictions (“The Embassy of Cambodia” (2013) and NW (2012) in addition to White Teeth), I show how their strategies of formal division (sectioning, chapter construction, and unsynthesized narrative remainders) address the problem of drawing boundaries around accounts of both personal attention and structural inequality. Smith uses the dyads of form and matter, parts and wholes, in her fiction to bring ongoing (and sometimes competing) stories of uneven development within a globalized modernity to bear on tarnished dreams of upward mobility and leftist demands for collective resistance against neoliberal policies of privatization.

Testo completo

Abstract (sommario):

Periodontal tissue destruction is the deterioration of tooth-supporting components, particularly the periodontal ligament (PDL) and alveolar bone, resulting in gingival recession, root exposure, tooth mobility and drifting, and, finally, tooth loss. The breakdown of the epithelial barriers by infection or mechanical damage allows bacteria and their toxins to enter and stimulates the immune response. The bacteria cause periodontal damage via the cascade of the host reaction which is crucial in the destruction of the connective tissue around the tooth. The OPG/RANKL/RANK system is the key player in bone regulation of periodontal tissue and was controlled by both immune and non-immune cells. This knowledge has predicated the successfulness of implant and orthodontics treatments with the predictable healing and regeneration of the bone and supporting tissues surrounding the teeth.

The start of burial and occupation at the three north Sicilian sites at around the beginning of the Holocene however, suggests that the appearance of these practices (in the archaeological record) may be related to particular circumstances of changed mobility within, and use of, the changing landscape in this area; earlier burials are known from peninsular Italy (Mussi 1986; 1987). Although the list is necessarily incomplete and the dating is uncertainly biassed, there is a suggestion in the figures as presented that burial in caves may have been confined to, or more common in, the final LUP and earlier Mesolithic; burial practice, at least in terms of place, may have been changing by the later Mesolithic. Interestingly, caves with Epipalaeolithic burials do not show continuity of use for the same practice into the Neolithic: different sites are chosen (see below). Arguments against marked regional differentiation are the generally similar burial position, and the occurrence of identical types of perforated deer teeth from Puglia and Sicilia. The perforated tooth from the Grotta del Cavallo in Puglia probably relates to the late Romanellian, perhaps at circa 10000-8000 cal.BC; those from the Grotta Romanelli to a similar date. Equivalence of practice, of course, does not necessarily correlate with equivalence of meaning, as is suggested by the different faunal contexts of these finds. The main hunted animals in Puglia were generally equids and bovines, but deer and pig in Sicilia. Discussion Italian Late Upper Palaeolithic and Mesolithic burials have been discussed by Mussi (1986; 1987), Mussi et al. (1989) and Zampetti & Mussi (1991). Although most of the burials are from outside the study area (mostly in Liguria), Mussi (1987) includes the Grotta di San Teodoro and Grotta delPUzzo (SIC), and the Grotta del Romito (CAL). She considers differences to reflect different emphases and conditions of social reproduction (1987: 45ff). In scheme A only certain sex-age individuals were buried, perhaps related to the circumstances of their death. She suggests that male hunters are represented at the Grotta di San Teodoro (although revision now suggests three tentatively identified females: Mussi 1987: 46; Fabbri 1993). In contrast, the burials at the Grotta del Romito represent scheme C, with both males and females, reflecting increased emphasis on social reproduction through exogamy (Mussi 1987: 47-8). She also notes the apparent contemporaneity of the first occupation and burials at the Grotta di San Teodoro, and argues that this represents the "colonisation" of Sicilia at a time when it was still "almost deserted" (Mussi 1987: 47-8). A similar argument is expanded by Zampetti & Mussi (1991), in which they also consider the evidence of 'art'. They argue that in the early Late Upper Palaeolithic there were burials of high-status individuals, perhaps related to control of information and partner exchange in a sparsely-populated landscape (Mussi 1987: 156). By the final Late Upper Palaeolithic they argue that there is more evidence of concern with descent, perhaps more stabilised (partner) exchange networks, and less evidence of pre-eminent individuals in the burials (Mussi 1987: 157). Stimulating though their interpretations are, in attempting to relate burial modes to changing social organisation and mapping of the social landscape, one might criticise some of the work in detail: for example, the burials from the Grotta del Romito are difficult to visualise as partners (see below). Any interpretation must be preceded by the realisation that the sample is extremely small and is already uncertainly biassed by accidents of excavation. Only certain people may have been buried; and the survival and excavation of burial (or other disposal sites) may be skewed. Thirdly, the representation of remains within those sites may be biassed, for example by the lower survival rates of infant and child remains. However, assuming that the sample is at least partly representative of the practices surrounding the dead, the following suggestions may be made." In Gender & Italian Archaeology, 70–75.

Abstract (sommario):

The paper presents a novel technique for the kinematic analysis of a geared mechanism manufactured through 3D printing technology. In the syllabus of the undergraduate 3D Printing course, one of the student projects is to manufacture a spur Norton type gear box which includes a planetary mechanism for engaging its three planets, thus three output velocities for the gear box are obtained. The connected elements (carriers, gears, planets) are fabricated without any involvement of assembly operation. At the prototype stage, a CAD model of the mechanism is created and a search for abilities and limitations of the mechanism are required. The analysis of abilities of motion includes determination of mechanism mobility (DOF). A step by step simple technique is presented for determination of the rank for the matrix of coefficients from the kinematic equations. Thus, the DOF is the difference between the number columns and the rank previously determined. The steps required in the analysis are: numbering of links and joints, graph attached to mechanism, matrix of incidence cycles-nodes in graph, and determination of its rank by using Mathematica commands. For the set of base cycles are automatically generated independent scalar equations. The matrix, denoted velocity matroidal, has the coefficients for the mechanism’s unknown absolute angular velocities-determined based on an analogy to a system of parallel forces from static equilibrium, angular velocities being considered analog to the “forces“. The relations between the input-output links’ absolute angular velocities are determined. The coefficients in the kinematic equations for velocities are written as function of gear ratios. The number of gear teeth can be selected also for the desired input-output speed ratios.

Abstract (sommario):

Bioengineering is a technological miracle of health care and future health hope. From the entrepreneurial contributions of William Kolff with the original handmade dialysis machine to the application of the x-ray to medical diagnostics and treatment, biomedical pioneers brought technology to medical care, often at great personal risk. Few can conceive the magnitude of the impact of technology on our ability to return the sick and disabled to function. The “simple” steel and plastic hip implant is a technological wonder. The human is the most demanding of systems to be repaired by technology. The stress levels, cycle loading, chemical degradation and even biological rejection are without precedent in engineering application. Reliability is expected to be near 100%. Psychological and cosmetic compatibility are severe constraints. The current quality of life of many (if not most) of us is dependent upon technology, and forefront technology at that. The dentist no longer hurts and our teeth last longer. Numerous “replacements” are cosmetically acceptable. Medical diagnosties are everywhere, but have a long way to go. Emergency medicine is high-tech. The wonders of bioengineering are in our present and in our future. It is informative to review our bioengineering heritage from early orthopedics (splints, peg legs and crutches), through mobility facilitation (wheelchairs) and internal repair (aortic patches and arterial replacement) to modern diagnostics (MRI) and organ replacement (artificial hearts, kidneys, etc.). A recent renewed interest in biomedical devices paralleling the decoding of the genome and the proposed genetic future portends what Dr. Francis Fukuyama of Johns Hopkins called “Our Post Human Future.” We will explore our historical pathway to what we will call “our better human future through bioengineering.”

Abstract (sommario):

The development of optimized fitting body armor is critical to the fightability and protection of our warfighters and first responders. Body armor systems generally worn by warfighters consists of three protective portions: rigid plates, a soft armor insert, and a carrier/vest. Rigid plates are inserted into the front, back, and sides of the body armor to provide a higher level of protection for the wearer, while the soft armor is positioned behind the plates and in areas of the body where a lower level of protection is acceptable or required for mobility and comfort. Previously, a comprehensive fit mapping study on the family of armor plates to investigate the relationship between the coverage, anthropometry and mobility relative to size specifications of torso and side plates was conducted (Choi et. al., 2017). There is a delicate tradeoff between covering more (i.e., a greater area of protection) while not degrading the wearer’s mission performance (primarily their mobility). However, some level of mobility degradation is unavoidable. Choi et. al. (2017)'s results quantitatively defined the impact of coverage on mobility, visualized the mobility degradation as coverage increase, and set the allowable mobility degradation to be 10%. The coverage corresponding to the allowable mobility degradation was then converted into anthropometric dimensions. Accommodation envelopes for the current U.S. Army torso plates, relative to the male and female US Army population, were reported. Final size tariffs were calculated using the front plate. A sizing system for the back plate and/or side plates were not developed.This current study explores a theoretical framework for ballistic rigid plate size optimization for the front, back and side plates. When the protection coverage is maximized with minimal mobility degradation, the system would be considered optimized. For this study, minimal mobility degradation was set to 10%. For the front plate, Choi et. al. was revisited to retrieve the maximum width and length while limiting the mobility degradation to 10%. Chest Breadth, was measured using the ANSUR II (Gordon et. al., 2014) procedure, and Suprasternale -Tenth Rib Length was used to derive the width and length of plates, respectively. Then, a specification of the front ballistic plate, given anthropometric characteristics of the current U.S. Army population was developed from a reverse engineering approach. Theoretical accommodation envelopes for each front plate size were then developed and plotted against the current ANSUR II data. Once the front plate sizing system was developed, anthropometric characteristics of cases within each accommodation envelope per size were investigated to develop the required size specifications for the back plate. The width of the back plate shares the width of the matching front plate, but the length takes into account the back length, from the Cervicale -Tenth Rib Length. Size specifications for the side plates were also developed. Given that the front and back plates are worn together; the maximum width of the side plate is defined by the surface availability at the location of the tenth rib level. The side plate length is defined using the distance between Tenth Rib and the Axilla. A theoretical size system for a family of rigid armor plates is presented in a series of tables as well as bivariate plots. A detailed process for plate size prediction and the interaction between the front, back and side plates is presented.

Abstract (sommario):

Bedari is a rights based NGO working in Pakistan for promotion and protection of human rights of women and girls. Girls’ Secondary Education is one of the core themes Bedari works on. Bedari believes that education is not only about acquiring a degree or a certificate, it is about the life skills and about knowledge around the rights and the capacity to claim them. Bedari, during the last fifteen years, has supported 1000s of girls to continue their education by enhancing their mobility, helping them strengthen their life skills and asserting their agency. During this, Bedari has gained marvelous understandings of community perspectives and barriers to girls’ education at community and policy levels. Bedari has learnt that a small contribution towards enhancing girls’ mobility not only ensures their access to education, but also contributes in their empowerment, reduces the incidence of child marriages and enables them to deal with gender based violence. // Session Objectives: // Demonstrate how small contributions in girls’ mobility and self-growth through community engagement can empower them and ensures access to education. // Share the good practices of working with government to enhance girls’ secondary education // Showcasing key learning around working for educating girls with disabilities // After a short presentation on the context of Girls’ Education in Pakistan, the moderator will invite the panelists for the discussion. Discussion will be in the form of a talk show. The questions will be around; their experiences (specifically in COVID Context), opportunities to work around inclusion and equity, challenges and their mitigation, and key takeaways. The panelists from different stakeholders including civil society, donor organization and government expert will be a great mix to provide the audience an insight on above mentioned themes from different perspectives. It will provide an opportunity to the participants from different countries to explore the possibilities of replication in their context.
