Cone beam computed tomography (CBCT) provides a precise three dimensional analysis of vicinity of Impacted Mandibular third molar (IMTM) which helps in surgical decision making.Objective: Objective of this study was to analyze the pattern of IMTM and the relationship of inferior alveolar canal to the tooth in 68 patients presented in year 2014 University Dental Hospital, Sri Lanka. Methods:The study sample included 112 IMTM teeth in 68 patients (54.5 % females, 45.5 % males) with average age of 28 years. Preoperative radiological assessment of IMTM was carried out with the aim of analyzing relationship of inferior alveolar canal to the roots of IMTM, analyzing their morphology, predicting anticipated difficulty in exodontia of IMTM and complications such as damaging the inferior alveolar nerve Results: Pell and Gregory Class I B pattern of impaction was predominant in the sample with mesioangular impaction being the most commonly occurring angulation of impaction. The Inferior alveolar canal was placed on buccal aspect of root apex in 35.7% of cases whereas in 33.9% of cases it was lingually placed. Conclusion:In conclusion the Pattern of impaction and the morphology of IMTM in current study comply with international norms except in few aspects.

Introduction: This study aimed to assess attitudes, confidence in practices and perceived barriers toward the promotion of tobacco cessation in the dental setting among clinical dental students in Sri Lanka. Methods: Role of dental schools on moulding future dental professionals with regards to education on tobacco cessation promotion is remarkable. A cross-sectional descriptive study was conducted on all the dental students from clinical years in 2018 using a self-administered structured questionnaire. Ninety-four per cent of the dental students from clinical years of faculty of dental sciences, University of Peradeniya, Sri Lanka completed the questionnaire (65% Females and 35 % Males) with a mean age of 24.65+ 2.24 years.Results: Clinical dental students possessed positive attitudes towards the professional responsibility of dentists in tobacco cessation whilst only 34% strongly agreed counselling offered in the dental setting has an impact on the same. More than half of the students remained neutral or disagreed the fact that nicotine replacement is within the scope of dentistry. Respondents expressed their confidence in tobacco cessation counselling. They identified “patients’ disinterest in receiving advice” as the main barrier to perform tobacco cessation practices in the dental setting. It is prudent to include formal education on tobacco cessation to the undergraduate curriculum of dental students to alleviate misconceptions related to practices of tobacco cessation in dental settings. Conclusion: It is of prime importance to identify training needs related to tobacco cessation promotion among dental undergraduates and compose a separate training module for them.

Highlights• In cleft patients, secondary alveolar bone grafting provides stability to the maxilla.• Impacted and missing teeth pose a challenge in developing stable occlusion.• Case report describes the simultaneous auto-tooth transplantation with secondary ABG.• Only one such previously reported case in scientific literature.• This treatment option provides aesthetically and functionally stable results.

Bronchogenic cysts are rare and benign congenital malformations. They arise from ventral surface of foregut during development and commonly present in mediastinum and intrapulmonary region. Bronchogenic cysts are often incidental findings in childhood. Majority of them are symptomless and rarely associated with symptoms such as stridor in neonates, dysphagia, dyspnea on exertion, and recurrent infection. Here we present a case of a bronchogenic cyst presented as Submandibular swelling in an adult a rare presentation.
