Prevalence of dens invaginatus in Jordanian adults

Aim To assess the prevalence of dens invaginatus in a sample of Jordanian dental patients. Methodology The data were collected from examination of 3024 radiographs from a random sample of 1660 patients showing 9377 teeth. A tooth was considered having dens invaginatus if an infolding of a radiopaque ribbon-like structure equal in density to enamel was seen extending from the cingulum into the root canal. Results Teeth with dens invaginatus were found in 49 prevalence was 2.95%,. Bilateral dens invaginatus was seen in 12 patients, whereas unilateral dens invaginatus was demonstrated in 37 patients. Dens invaginatus was detected in 61 teeth out of a total of 9377 for a tooth Prevalence of 0.65%. Maxillary lateral incisors were the most common teeth affected with the condition (90% of cases). Conclusions Dens invaginatus is not common, but it is an important anomaly The availability of such data may alert the dental practitioner to anticipate the percentage of teeth having difficulties during endodontic treatment.
