There are various anthropometric measurements available to evaluate the reliability of Berry’s biometric index in two different population groups for selection and arrangement of artificial teeth. Berry’s biometric Index (BBI) is one of the method to measure the size of anterior tooth. It is measured by measuring the bi-zygomatic width of patient which is divided by 16. To evaluate and determine the reliability of Berry’s biometric Index in Two Different Population groups, native Indian and native Malaysian. A total of 100 participants, in which 50 Malaysian and the other 50 Indian were participated in this study. The measurements were taken by using a vernier caliper. The measurements were divided into extra oral and intra oral. The extra oral is the bizygomatic width. The intra oral is the width of the maxillary central incisor. By using Berry’s Index formula, the size of the width of central incisor tooth can be determined. For Indian population, the mean values for extraoral width is 0.9202cm. Meanwhile for the intraoral measurement is 0.8266cm. For Malaysians population, the mean values for extraoral width is 0.8024cm. Meanwhile for the intraoral measurement is 0.7526cm. The standard deviation between the measurement of the actual width and the formulated width is only 0.0071 for Malaysian population and 0.0134 for Indian population. The result show a good positive correlation between the upper central incisor and the Berry’s biometric measurement in Malaysian population (r=0.97) compared to Indian population (r=0.83). The selection of maxillary central incisor by Berry’s Index formulae is a useful method as only a slight difference between the actual lengths of the tooth and the formulated one, which is the standard deviation between the measurement of the actual width and the formulated width. Therefore, Berry’s Index formula are proven reliable.
