Objective: To determine variations in the location of mental foramen by means of Cone Beam Computed Tomography.

Study Design: Descriptive Cross-sectional Study.

Place and Duration: Rehman College of Dentistry, Peshawar from 1st Jan 2018 to 30th June, 2019.

Methodology: The Cone Beam Computerized Scans were evaluated and Mental foramen positions were categorized into Type I (beneath apex of 2nd premolar) type-II (between 1st and 2nd premolar) type- III (between 2nd premolar and 1st molar) and type-IV(distal to 1st molar root apex). Mental foramen position was stratified among left and right side of mandible.

Results: On evaluation of 264Cone Beam Computerized Scans, the most common location of Mental foramen was type-I (56.44%), followed by type-II (39.20%). Type-III and type-IV were having the prevalence of 3.98% and 0.37% respectively.
