Abstract

This retrospective study determined the prevalence of early loss of deciduous molars in patients enrolled at the Pediatric Dentistry clinic at the State University of Paraíba. A review of 515 patient records were analyzed, registered in a form. The following variables were analyzed: gender, age, type of deciduous molar loss, region (maxilla or mandible) and side (right and left). It was observed that the prevalence of early tooth loss was 15.1% and there was a similar distribution between the genders. In regard to age, the greatest frequency of tooth loss involved patients at 7 years old (32.1%). There was a similar distribution of tooth loss between the maxilla and mandible regions, at 43.6% each, with the left side being the most involved (41%). The second upper left deciduous molar was the most commonly missing tooth (17.9%), followed by the first upper right deciduous molar (16.1%). It can be concluded that the prevalence of early loss was lower and that the upper primary molars were the most commonly missing teeth.
