Estudio de la erupción de la dentición permanente en niños y adolescentes de la Comunidad de Madrid (España)

Abstract

Introduction: The moment of appearance of a tooth in the oral cavity has been studied, over the years, by different authors, for its relation to different factors (systemic and environmental) and due to its influene on different areas of dentistry. Material and method: With the aim of analyzing the eruptive pattern of our population, we decided to carry out a descriptive transversal-type study on the characteristics of the eruption of permanent dentition in 752 children and adolescents of the Community of Madrid (Spain), of which 46.2% were males and 53.8% were females. Results: We observe that the permanent teeth emerge in the oral cavity between 6.99 and 12.45 years of age in the girls and between 7.06 and 12.81 years of age in the boys. In general, we did not find statistically significant differences as regards the moment of emergence of the homologous contralateral teeth. We observed that the teeth of the lower arch erupted before those of the upper arch and that the eruption of the permanent teeth occurred earlier in the girls than in the boys. Conclusions: The order of appearance of the permanent teeth in both sexes was: first molar, central incisor (on the right side; on the left side the central incisor precedes the first molar), lateral incisor, first premolar, second premolar, canine and second molar in the upper arch. And in the lower arch: central incisor, first molar, lateral incisor, canine, first premolar, second premolar and second molar.
