Background: The aim of the study was to investigate the prevalence of dens invaginatus in a sample of North Indian dental patients and their distribution among different types of teeth.Material and methods: The data were collected from radiographic examination of 6048 periapical films showing 18754 teeth from a random sample of 3320 patients. A tooth was considered having dens invaginatus if an infolding of a radio-opaque ribbon-like structure equal in density to enamel was seen extending from the cingulum into the root canal.Results: Dens invaginatus were detected in 104 teeth (tooth prevalence = 0.55%). Maxillary lateral incisors were the most commonly affected teeth (88.3% of cases and prevalence of 5.6%), followed by maxillary canines (21.7% of cases prevalence of 1.5%). Teeth with dens invaginatus were found in 80 subjects (person prevalence = 2.4%). Bilateral dens invaginatus were seen in 24 patients.Conclusions: Attention should be paid to the presence of dens invaginatus and the treatment problems associated with it.
