Aims and Objectives: The aim of this study was to assess the validity of interalar distance as an aid in maxillary anterior teeth selection in Thrissur, Kerala, Indian population. The study also evaluated whether interalar distance and maxillary anterior teeth undergo any changes as age increases in this population and whether there is a gender difference in these parameters in this population. Materials and Methods: A study was planned on 1200 participants in Thrissur Municipal Corporation area, Kerala, India, with the aim of checking the validity of interalar distance as a successful aid in maxillary anterior teeth selection. The collected data were analyzed using SPSS version 21.0. Mean standard deviation and 95% confidence intervals were estimated. Student's t-test was used for comparison between gender and two age groups such as 18–25 and 40–50 years. One-way ANOVA analysis was done for combined effects. Results: The study showed that there is a high statistical significance between the interalar distance and the mesiodistal width of six maxillary anterior teeth in females (P < 0.01) and no significance in males. Conclusion: The study concluded that, within the population evaluated, there was a high significant correlation between interalar distance and the mesiodistal width of six maxillary anterior teeth in both males and females. Both interalar distance and mesiodistal width of maxillary anterior teeth showed a significant increase in size as age increases. There was a significant increase in size difference for males compared to females in relation to interalar distance and not for mesiodistal width of maxillary anterior teeth.
