Sequence and chronology of eruption of deciduous teeth in children from Itajaí city (SC)
Journal Title: RSBO - Year 2010, Vol 7, Issue 4
Abstract
Introduction: Nutritional and development variables both at birth and early age can predict the number of erupted teeth that children will have in their oral cavity.Objective:This study aimed to report the time and sequence of eruption of deciduous teeth in children from Itajaí city, comparing data regarding to teeth, gender, age, socioeconomic level, and breast-feeding.Material and methods:A cross-sectional study was performed with 1297 children divided by gender and age. In order to test the hypothesis that tooth eruption varies between males and females, t-test was comparatively applied.Results: It was observed an earlier male eruption time of tooth #61 (left upper central incisor), starting at 10.6 months and finishing at 30.9 months, with tooth #65 (left upper second molar). Female eruption time started with tooth #71 (left lower central incisor), at 12 months and finished at 31.55 months with tooth #85 (right lower second molar). The analysis of mean eruption values by t-test showed a contrast between genders for the following teeth: #63, #72, #73, and #83.Total male and female mean eruption time was 20.30 months and 19.95 months, respectively. It was observed that children who had been exclusively breastfed for over than six months, showed non-statistically significant greater mean eruption times Conclusion: Such values predict that both sequence and mean eruption time would be genetically determined. Environmental influences as breast-feeding type do not necessarily alter the eruption time means.
