RADIOGRAPHIC STUDY OF MENTAL FORAMEN IN CHITWAN POPULATION
Background: Knowledge about the type & position of mental foramen is very much important landmark for dentists to perform any surgical procedure in the vicinity of mental foramen. The purpose of this study was to determine the most frequently occurring type & position of the mental foramen in Chitwan population using digital Panoramic Radiograph.
Methods: This cross-sectional retrospective study was conducted on 500 (250 Male& 250 Female) digital panoramic radiograph which were collected from the department of Oral Medicine & Radiology. The type & position of Mental Foramen was analysed with Dicom viewer. The data obtained was statistically analyzed by with descriptive and inferential statistics using SPSS Version 20.
