Accessory lingual mental foramen: A case report of a rare anatomic variation.

INTRODUCTION: The mandibular nerve and the mental foramen have occasionally shown variations in its anatomy. This report aims to present a case of lingual mental foramen recognised on three-dimensional cone beam computed tomographic imaging (CBCT). CASE REPORT: Routine Orthopantomogram (OPG) and CBCT images were evaluated to assess the status of impact third molars in a 31-year-old female who had visited the dental clinics in our institution. The OPG image failed to reveal any anatomic variation in the position of the mental foramen. On tracing the course of the mandibular canal in CBCT images, two foramina were traced at the region of premolar. One opened towards the buccal cortical plate at the normal position of the mental foramen and an accessory lingual mental foramen had an opening on the lingual cortical bone at the same level as the mental foramen. CONCLUSION: Understanding variations of the mental foramen is extremely essential in dentistry to carry out successful anaesthetic or surgical interventions and to avoid complications such as nerve damage or excessive bleeding.

Tobacco Cessation Scenarios Among Healthcare Profession Students: A Multidisciplinary Study

Background: It is acknowledged that the most effective means to contain the tobacco epidemic is to involve healthcare providers across various disciplines. The present study was undertaken to gain a comprehensive insight into various factors that determine the efficacy of multidisciplinary approaches in tobacco control. Methods: A cross sectional study design using a structured, pretested and self-administered questionnaire was employed in the present study, conducted among medical and dental interns and final year nursing students. Respondent demographics, knowledge, attitude, behaviour, perceived effectiveness and barriers, and willingness to participate in tobacco cessation were assessed. Results: A total of 268 subjects participated, with mean knowledge, attitude, behaviour, perceived effectiveness and barrier scores of 69. 7%, 89.0%, 72.0%, 80.6% and 88.6% respectively. There were significant differences among the mean scores of the study domains across the 3 disciplines. The majority (92.91%) of the respondents were willing to participate in tobacco cessation activities, but only 14.2% had previously received relevant training. Regression analysis revealed that the significant predictors of behaviour scores were gender, course, attitude and perceived effectiveness; those for willingness to undertake tobacco cessation activities were course, attitude, behaviour and perceived barriers. Conclusions: The study highlighted the willingness but low previous training among the participants and also identified factors that determine t behaviour and willingness to undertake tobacco cessation activities. The study emphasizes the need for modification in the policies pertaining to curricula of medical, dental and nursing training programs.
