A mesiodens is a supernumerary tooth located in the palatal midline between the two maxillary central incisors. The overall prevalence varies between 0.15 and 1.9%. The present study aimed to evaluate the epidemiological characteristics of mesiodens in the pediatric population.A longitudinal prospective study was carried out in 7932 children to determine the prevalence of mesiodens. The following data were also recorded: age, sex, shape, sagittal position, orientation, eruption status, number and complications caused by mesiodens.The prevalence of mesiodens in the present study was 0.8%. The sex ratio was 1.78:1, favoring boys. The majority of mesiodens (67.9%) were conical in shape, followed by the supplemental (17.9) and tuberculate (14.1%) types. 71.8% of the mesiodens were palatally placed, 25.6% erupted on the arch and 2.6% were labially positioned. A majority of the mesiodens (62.8%) were vertically aligned. Inverted and horizontal positions were observed in 30.8% and 6.4% of the cases. Most of the mesiodens (53.8%) were impacted, and 14 children had two mesiodens. Most of the mesiodens were associated with complications, and only 26.9% were asymptomatic.The prevalence of mesiodens was 0.8% .Conical shape, palatal position and vertical orientation were common characteristic observations in the study.
