    Aim: The objective of the study was to determine the prevalence of mesiodens along with other epidemiological characteristics. Materials and methods: A retrospective evaluation of data of patients was done to calculate the prevalence of mesiodens in 60,590 children (33,038 boys and 27,552 girls) in age range from 4 to 12 years. In addition to the prevalence, age, gender, number, morphology, orientation, and complications associated with it was also recorded. Results: The prevalence of mesiodens was estimated to be 1.12% (680 cases) with male–female ratio of 3.22:1. The dentition-wise prevalence was 5.88% in primary dentition stage, 83.53% in mixed dentition stage, and 10.59% were in permanent dentition stage. Out of the 680 patients, 149 (21.91%) had two mesiodens, whereas 531 (78.09%) cases had 1 mesiodens. Conical shape was the most common type (92.76%), followed by supplemental (4.7%), odontome (1.33%), and tuberculate (1.21%). In all, 67.67% mesiodens were in a vertical position, 28.35% were in an inverted position, and 3.98% were in a transverse position, and 689 mesiodens (83.11%) were erupted and the remaining 140 (16.89%) of the cases were unerupted. In all, 46.56% of the mesiodens were palatally positioned, and root formation was complete in 65.86% cases, and 34.14% had incomplete root formation. Complications caused by mesiodens were malalignment of maxillary centrals (53.09%), noneruption of incisors (17.94%), and diastema (28.97%). Conclusion: Mesiodens is the most common form of supernumerary teeth in permanent dentition. Early detection and management of all supernumerary teeth is a necessary part of preventive dentistry.
