Objectives: Mesiodens are the most common supernumerary teeth, occurring in 0.15 % to 2.2 % of the population. The aim of the present study was to analyze the frequency and radiological features of mesiodens in the pediatric population. Material and methods: The study was based on the radiographic evaluation of 4133 pediatric patients of the age range of 4-15 years, attending the Department of Oral Medicine and Radiology during the time period between September 2008 to December 2012. In addition to the presence of a supernumerary tooth between the 2 central incisors, data regarding the number, position, shape and associated complications were also recorded. Results: The prevalence of mesiodens in the present study was 1.4%. The prevalence was estimated using a 95% confidence interval. The ratio of boys to girls was 1.8:1 and majority of cases (89.7%) had 1 mesiodens. Most of the mesiodens (59.6%) were aligned in a vertical position. 39 mesiodens (62.9%) were impacted, while 14 (22.6%) were partially erupted and only 9 (14.5%) were completely erupted into occlusion. The main complication associa-ted with the mesiodens was midline diastema (28.6%) and 16 patients were asymptomatic. Conclusion: Mesiodens can result in spacing in the arch, delayed or ectopic eruption of the permanent incisors
