Abstract:
OBJECTIVE: The purpose of this study was to locate the fracture sites and treatment modalities of the different fractures. MATERIAL AND METHODS: Patients treated at the Oral and Maxillofacial Department of Kantipur dental college teaching hospital and research center during a one-year period between 2014 and 2015 were retrospectively evaluated with respect to age groups, gender, etiology, localization and type of fractures, treatment methods and complications. RESULTS: 174 patients were included in the study, 142 (81.6%) males and 32 (18.4%) females, with a total of 244 mandibular fractures sites with a male/female ratio of 4.4:1. The most common causes of injury were falls (χ2=17.1607, P=0.0087) accounted for 139 (79.9%) of the fractures. The most common fracture sites, symphysis of the mandible being significantly (χ2=21, P=0.0008) affected than other sites. However, 96 (39.3%) and 132 (54.1%) of the fractures occurred on the right and left sides of the mandible respectively. Most patients had single (44.3%) and double (31.6%) fractures and this finding was significant (χ2=60.9314, P=0.0000). The fractures were successfully treated by arch bar and intermaxillary fixation, and open reduction and internal fixation. CONCLUSION: This study shows falls were the common cause of fracture and others being secondary.Symphysis was the common sites of fracture. Arch bar placement internal fixation and open reduction and internal fixation were the treatment modalities we used in our instution.

Title: Fracture Resistance of Roots Restored with Bioceramic Endodontic Sealer
Biography:
Abstract:
Aim/Objective: This research evaluated and compared the fracture resistance of the roots of teeth restored with bioceramic sealer against AH26 sealer, used in (Elements Free) continuous wave obturation technique.
Methodology: A total of 60 maxillary and mandibular anterior teeth were decoronated and distributed equally among 4 experimental groups, and two control groups. Group 1 samples (n=10) were decoronated only and not prepared, Group 2 (n=10) were prepared and instrumented only, Group 3 (n=10) were prepared by laser and obturated using bioceramic sealer and Elements Free obturation system, Group 4 (n=10) were prepared by laser and obturated using AH26 sealer and Elements Free, Group 5 (n=10) were prepared manually and obturated using bioceramic sealer and Elements Free, Group 6 (n=10) were prepared manually and obturated using AH26 sealer and Elements Free.
Results: Statistical analysis of fracture resistance values using the one-way ANOVA test (SPSS Version 20.0) revealed no significant difference between all the experimental groups.
Conclusion: It can be concluded that the BC sealer along with the laser preparation of the roots might have a potential in improving the fracture resistance of the roots although it was statistically non-significant.

Title: Dento-Skeletal dimensions among children with unilateral cleft lip and palate deformities
Biography:
Singh SP,Professor and Head,Unit of Orthodontics,OHSC, PGIMER, Chandigarh. He was submitted Dento-Skeletal dimensions among children with unilateral cleft lip and palate deformities.
Abstract:
Introduction and objective: Clefts of the lip and/or palate are the most common congenital malformations in the craniofacial region.1Generally clefts are divided into two groups, isolated cleft palate (CP) and cleft lip with or without cleft palate (CL/P). The causes of both cleft lip and palate (CLP) and isolated cleft palate (CP) are largely unknown. Etiology is considered multifactorial, with both genetic and environmental factors interacting.1According to the World Health Organization,2a CLP is a dental public health issue because of the oral conditions of the individuals and their psychological, aesthetic, and functional impairments.3
Evaluation of dental and skeletal dimensions among 4-6 year old children with unilateral cleft lip and palate deformities and to compare it with age matched normal non-cleft children
Methodology: 30 children with unilateral cleft lip and palate deformity with deciduous dentition were included in the study. Dental dimensions were done on study models which included occlusal relationship (sagittal molar and canine relationship, transverse and vertical relationship) and arch measurements (arch length, width and depth) using digital vernier caliper and depth gauge and skeletal dimensions included 19 angular and 4 linear measurements taken on lateral cephalograms and then compared with data of age matched 100 normal non-cleft children
Results: Cleft children had flush terminal plane molar relation and class I canine relation as the most predominant relationship. In transverse plane, all the segments i.e. anterior and buccal (canine, 1st molar and 2nd molar) on the cleft sides showed significantly lower scores(P<0.05) than the non-cleft sides, hence, transverse constriction was significantly(P<0.05) more on the cleft sides than the non-cleft sides.The vertical overbite was increased in cleft children. All the arch dimensions viz. arch length, arch width and arch depth were significantly(P<0.05) smaller in cleft children. The skeletal dimensions also showed similar trend with increased cranial angle and retrusive maxilla and mandible in relation to the cranial base and retroclination of upper and lower incisors was observed.
Conclusion: The cleft causes significant decrease in maxillary arch measurement and skeletally the maxilla and mandible were retrusive in relation to the cranium.

Title: Posterior Mandibular Tooth Socket Preservation with Amniotic Membrane and Allograft Bone versus Conventional Methods
Biography:
Seyed Ali Mosaddad,Undergraduate Student, Student Research Committee, School of Dentistry, Shiraz University of Medical Sciences, Shiraz, Iran.He was submitted Posterior Mandibular Tooth Socket Preservation with Amniotic Membrane and Allograft Bone versus Conventional Methods.
Abstract:
Introduction: Tooth socket preservation has become a key component of contemporary clinical dentistry. This term designates alveolar preservation that achieved by the immediate filling of the undamaged tooth socket with biomaterials. Different types of bone substitutions and membranes have been utilized for socket augmentation. Our goal was to evaluate the efficacy of the amniotic membrane, as a new material, on bone density in comparison with conventional methods in this study.
Material and Methods: In this randomized clinical trial 75 patients (48 females and 27 males) underwent mandibular molar extraction and socket preservation by using allograft bone in control group: allograft bone with collagen membrane in group 1 and allograft bone with the amniotic membrane in group 2. All 25 stages of socket preservation procedures in each group were done by the same surgeon and evaluated by the same radiographic machine. The data were statistically analyzed by SPSS software, one-way ANOVA and Tukey post-hoc tests. The P-value <0.05 was considered as significant.
Results: The results of this study showed that after 4 months the mean density difference in the extracted site was 1736.88 in control group; for patients who underwent socket preservation with allograft and collagen membrane it was 1746.20 and in cases, with allograft in addition amniotic membrane it was 1762.48.
Discussion and Conclusion: The results demonstrated that, compared with control group, both collagen membrane and amniotic membrane showed a higher mean bone density (P-Value =/998 and P-Value = /918), but this difference was not statistically significant. Whereas amniotic membrane showed a higher bone density than the collagen membrane, there are no significant differences between these two groups (P-Value =/994). Although socket preservation methods may be effective on alveolar bone contour stability, we cannot significantly confirm the efficacy of these methods on bone quality and density.
