Frequency and Characteristics of Mesiodens in Indian School Children: A Retrospective Radiographic Study

Objective: To determine the frequency and characteristics of mesiodens in Indian school children.

Material and Methods: 1232 radiographs of patients attending the Department of Oral Medicine and Radiology of the age group of 4-15 years studied for the present retrospective study. The intraoral periapical radiographs and occlusal radiographs of the premaxilla were examined to determine the presence of mesiodens. The data regarding the presence of mesiodens, number, position, location on the arch, shape and associated complications were recorded.

Results: Eleven patients had 14 mesiodens, with a frequency of 0.8%. The ratio of boys to girls was 1.2:1. Maximum mesiodens observed in the age group of 7-9 years. Most of the mesiodens were conical in shape and found on the palatal side. Fifty percent of the mesiodens were unerupted. The majority of patients (57.1%) had vertically positioned mesiodens. Midline diastema was the most common complication due to mesiodens (66.7%).

Conclusion: Routine check-up during the primary dentition and mixed dentition stages helps for early detection of mesiodens and thus preventing complications. Early identification is useful for planning comprehensive management, initiating proper consultation and referral for evaluation and treatment
