Abstract

Dental forensic or forensic odontology had played an important key in identification of person involved in the disaster, criminal crime and ethnic identification. The investigator will get the needed informationfrom the tooth prints, radiograph, rugoscopy, cheiloscopy, molecular methods and photographic study. X ray image is one of the aid in the investigation, as the investigator can retrieve the information from the x-ray of the victim. In this paper we present a method to segment the premolar teeth from the x- ray image using OTSU and watershed algorithm. Data were collected from Faculty of Dentistry, Universiti Sains Islam Malaysia (USIM). The target area of segmentation is premolar teeth for the early tooth development stage (TDS).The methods we used were OTSU and watershed algorithm.
