Deciduous dental eruption chronology study in children attended in clinics of the Dentistry course of Univali
Journal Title: RSBO - Year 2009, Vol 6, Issue 3
Abstract
Introduction: The research of deciduous tooth eruption is an issue that should be considered, because the scarcity of literature on the matter justifies the need to enlarge the bibliography, mainly in Brazil.Objective: The purpose of this study was to determine the chronology of deciduous eruption of the first erupted tooth, as well as if there is any predominance in relation to sex and dental arch, through analysis of patient records of children attended in clinics of the Dentistry course of Univali. Material and methods: Data was collected from 836 clinical records. To analyze the results, data was tabulated in 3 groups comprising the dental elements and their contralaterals that first erupted. These 3 groups were divided into subgroups, according to sex (male and female), with 402 teeth from male children and 434 teeth from female children. Each dental group (51/61, 52/62 and 81/71) subdivided by sex was organized according to age, in months in which the eruption occurred. These ages varied from 2 to 20 months. Results:The first tooth to erupt in the oral cavity was the lower central incisor.Conclusion: It was possible to conclude that there is no difference in eruption chronology of the deciduous teeth between males and females.The predominance of the first eruption, in relation to the maxillary teeth, is in the jaw for both sexes, and the deciduous dental element that first erupted in the oral cavity is that of 81/71.
