Dental agenesis is one of the main anomalies of dental development therefore presents reflections on aesthetics and chewing. This study about the prevalence and hereditary behavior of agenesis of permanent teeth in the population of Uberlandia - MG, conducted with selected patients in 9407 trough radiographic exams of a particular radiological clinic from January 2006 to December 2007.The initial sample had 109 males and 145 females, totalizing 254 patients with at least one agenesis except for third molars, showed that 2,8% had agenesis without gender preference. The agenesis of the upper arch were represented by the lateral incisor isolated or both at the same time and in the lower arch, second premolars also separately or both. The upper agenesis showed predilection for females while the lower arch was the same for both genders. The study of hereditary behavior was conducted with the families of twenty-five patients from the initial sample who answered telephone calls about the presence of agenesis in the family. Ten patients denied and fifteen reported that some member of the family have agenesys and the informations were used to make individual heredrograms that suggested autossomal recessive pattern, showed that the repeats were significant in those who had agenesis of the upper lateral incisors with either one of two at the same time. Still suggests a possible stability in the inheritance of agenesis of maxillary lateral incisors that could be based on the study of molecular biology to determine the genetic markers.
