Teeth are one of the most important biological indicators of ageing due to their high mineral content and resistance to change after death. Dental maturity indicates biological age for criminal, forensic, and anthropological purposes. When no information is known about the deceased, forensic human identification requires age estimation. This study used Lamendin's and Kvaal methods to evaluate and construct a regression model for dental age assessment in extracted single-rooted mandibular premolar teeth in south Indian population. Mandibular extracted first premolars were obtained from the patient from 15 to 75 years old. The patient details were blinded before analysis. The root height, root translucency, and periodontosis parameters were measured using Lamendin et al's technique. Based on the method proposed by Kvaal et al the morphological measurements of the teeth were calculated with six measurements for each tooth. In the results to determine the mean and standard deviation, descriptive statistics were used, and unpaired t-tests /Pearson correlation were used to compare age to other parameters and P-value <0.05 indicated as significant. South Indian population had a greater standard error of estimated age using Lamendin et al. and Kvaal's approach. Then modified Lamendin's and Kvaal's formula was used to South Indians and yielded accurate findings. This study concludes that the formula which was derived from the French population(Lamendin's) and the Norwegian population(kvaal's) does not apply to the South Indian population.
