Aim: The aim of this study was to study the prevalence of dens invaginatus (DI) and palatogingival groove (PGG) in maxillary lateral incisors, and the occurrence of apical periodontitis in association with these anomalies in North Indian population. Methodology: Maxillary lateral incisors in 163 cone-beam computed tomography scans were assessed to determine the presence of DI and PGG. Anomalies identified were then classified as per Oehler's and Gu's classification, respectively. Their side and gender predilection and association with apical and lateral radiolucency was also studied. Statistical Analysis: Descriptive data were reported as percentages. Chi-square analysis was used to determine the association with gender and side predilection. Results: DI was present in 13.5% of the scans, while PGG was present in 7.3% of the scans. No significant gender and side predilection was observed. 6.67% of lateral incisors with DI and 25% of lateral incisors with PGG had an associated apical radiolucency. 33.33% of lateral incisors with PGG had an associated lateral radiolucency. Conclusions: There is a high prevalence of DI and PGG in maxillary lateral incisors.
