Age estimation plays an important role in forensic medicine, clinical dentistry and archaeology for the identification process. The age estimation becomes complex in adults when the mineralization process of all the teeth has completed. The objective of this study was to estimate the age of Malaysian adults by using Gustafson’s method observed on the dental panoramic tomographs from mandibular premolars. Four hundred dental panoramic tomographs of 227 female and 173 male Malaysians aged between 18 and 74 years old were reviewed. The characteristics of secondary dentin formation, cementum apposition, periodontal recession and attrition were evaluated in all the mandibular premolars. There was a significant difference between right and left mandibular premolars using the paired t test (p<0.05). The linear correlation of the individual characteristics with the chronological age of each premolar was examined. The multiple regression analysis was done for the equation of age estimation. The R values amounted between 0.77 and 0.79 with the mandibular left second premolar having the highest value. The method devised by Gustafson can therefore be used for forensic age estimation for the Malaysian population as it is considered as a less invasive method. © 2021. All rights reserved.
