Aim:The aim of this study was to describe the characteristics of the mandibular third molar at highest risk for acute pericoronitis using clinical and radiographic analysis.Materials and Methods:A total of 120 patients ranging in age from 18 to 55 years suffering from pericoronitis were examined. Subjective and objective observations were recorded that included the age, gender, angulation of partially impacted mandibular third molar, the frequency of pericoronitis in a year, the presence of impinging maxillary third molar, the extent of soft tissue coverage over the impacted mandibular third molar, the clinical signs evaluated in the patient, the class and position of the impacted mandibular third molar, and the presence of distal radiolucency with respect to the impacted mandibular third molar.Results:The results obtained in the study indicate that pericoronitis is associated more in the age group of 26–35 years and is more commonly reported in the female gender. Distoangular partially impacted mandibular third molars impacted at Class II and position B seem to be at the highest risk of developing pericoronitis.Conclusion:The results obtained in the study indicate that pericoronitis is associated more in the age group of 26-35 years and is more commonly reported in the female gender. Distoangular partially impacted mandibular third molars impacted at class II and position B seem to be at the highest risk of developing pericoronitis.

Open reduction and internal fixation should be given due consideration in the management of displaced mandibular condylar fractures and is associated with minimal morbidity using retromandibular approach.

Background The present study aims to assess the knowledge and attitude about needle stick injuries and sharps disposal. Methods A self designed questionnaire of 15 questions was handed out to 200 participants including undergraduate students (group 1), postgraduate students (group 2), faculty members (group 3) and auxiliary staff members (group 4). The data was collected and analyzed using Chi square test. Results Sixty-one percent of total participants reported of experiencing needle stick injury and 25.5 % knew that there could be several causes for this. Only 22 % of total population studied got the source tested. Immunization status of group 4 was very low and they also lacked the knowledge of sharps disposal and hepatitis C being spread by needle stick injuries. 57 % participants confirmed that there was no reporting facility and 66 % were not familiar with the guidelines of reporting.Conclusions There is a definite scope of improvement in terms of reporting and prevention of needle stick injuries. There is a need to improve knowledge and awareness of dental health care workers about the post exposure protocol.

Background Oral submucous fibrosis (OSMF) is a chronic disease of the oral cavity which presents clinically with burning sensation, leathery consistency of oral mucosa with palpable fibrous bands leading to reduced mouth opening. Though the evaluation of quality of life (QOL) in health care is gaining importance, researches regarding the evaluation of QOL in OSMF individuals are very sparse. Aim The aim of the present study is to evaluate the QOL assessment in OSMF patients through WHOQOL-BREF questionnaire. Methodology The study includes a total of 300 participants recruited from the outpatient department. The quality of life was assessed using the WHOQOL-BREF questionnaire. The raw scores for the physical health, psychological health, social relationships and environmental health domains were done on 4-20 scale suggested by the WHOQOL procedural manual. The analysis of variance (ANOVA) was used for the simultaneous comparison of mean scores for the four domains, and independent t test was used for the comparison of two means of domain scores. Results The participants with OSMF have a significant negative impact on the quality of life when compared with the participants without OSMF (P = 0.002). The environmental factors in the WHOQOL-BREF have shown a significant difference in the QOL of participants with OSMF than without OSMF (P = 0.001). Conclusion The oral submucous fibrosis has a negative impact on the quality of life in participants with OSMF specifically in social and environmental domains of the WHOQOL-BREF questionnaire.
