Specifically, the main objective was to verify the relation of the dental agenesies between the sorts feminine and masculine; esteem which the frequency of the involvement of the dental elements in this type of anomaly and to determine the most frequent localization . 1300 panoramic xrays had been analyzed and had shown that a bigger prevalence of thi s anomaly in the feminine sort exists (55,9%) and that of the total of the sample, 22.8% of the patients had dental agenesy and 77.2% did not present this anomaly of development. The tooth that presents greater frequency of this type of dental anomaly is the third molar one, as more prevalent in our sample he is as the daily pay -molar one, mainly the inferiors, after that the superior lateral incisor; e finally of most prevalent, first the daily pay-molar superior; the only tooth that did not present no occurrence of agenesy is first the molar one. The localization most frequent in this type of dental anomaly is in the jaw, in the right quadrant, followed of the left superior quadrant. In the jaw we have that the results of the two quadrants are lesser equivalents and that in the jaw. The analysis statistics of the results using the test of 2 (Qui-Quadrado) of Pearson showed that influence of the sort in the occurrence of the dental agenesy does not exist. The analysis for test T of Student, of the sample in relation to the type of tooth, localization of the dental agenesy, showed that difference does not exist statistics in none of the executed comparisons.
