Publication Left Accessory Mental Foramen in Dry Mandibles in Department of Anatomy in a Medical College: A Descriptive Cross-sectional Study(Nepal Medical Association, 2022) Tiwari, NripendraAbstract Introduction: The presence of accessory mental foramen is one of the anatomical variations in the mandible. The occurrence of accessory mental foramen can differ in terms of number, shape, and size or there can even be an absence of it. The aim of this study was to find out the prevalence of left accessory mental foramen in dry mandibles in the Department of Anatomy of a medical college. Methods: This descriptive cross-sectional study was conducted in a medical college among dry mandibles from 10 January 2021 to 10 June 2021. Ethical approval was obtained from the Institutional Review Committee (Reference number: 207202005). Intact dry mandibles were studied for the prevalence of left accessory mental foramen. A convenience sampling technique was used. Point estimate and 90% Confidence Interval were calculated. Results: Among 47 dry mandibles, the prevalence of left accessory mental foramen was found to be 4 (8.51%) (1.81-15.21, 90% Confidence Interval). The mean diameter of the left accessory foramen was found to be 1.02±0.03 mm. Conclusions: The prevalence of left accessory mental foramen in mandibles was similar to the studies done in similar settings.Publication Trismus among Preclinical Students in a Medical College: A Descriptive Cross-sectional Study(Nepal Medical Association, 2022) Tiwari, NripendraAbstract Introduction: Trismus is a condition of reduced mouth opening due to tonic constrictions of the muscles of mastication. Trismus greatly affects health-related quality of life and thus daily life activities. The aim of this study was to find out the prevalence of trismus among preclinical students in a medical college at a tertiary care teaching hospital. Methods: A descriptive cross-sectional study was conducted in a medical college from 10th July 2021 to 10th December 2021 for a period of five months. Ethical clearance was obtained from the Institutional Research Committee (Reference number: 0311202004). A total of 315 preclinical students studying at a medical college were included in the current study. Convenience sampling method was used. Point estimate and 99% Confidence Interval were calculated. Results: Among 315 students, trismus was seen in 14 (4.44%) (1.45-7.43, 95% Confidence Interval) . The clicking sound on the right side of the temporomandibular joint was found to be in 6 (42.86%), on the left side was 5 (35.71%) and that of both sides of the temporomandibular joint was 1 (7.14%) among the 14 students with trismus. The mean maximal interincisal mouth opening was found to be 33.4±0.46 mm in students having trismus. Conclusions: The prevalence of trismus was found to be similar to the other studies performed in similar settings among preclinical students in a medical college. Awareness on mouth opening exercises and timely management can help reduce trismus.
