Relationship between the socioeconomic status and the chronology and eruption sequence of permanent dentition

Resumen

Objective: Relate the eruption process in permanent dentition with the socioeconomic status. Methods: An epidemiologic, descriptive and cross-sectional study was carried out in the Spanish population, participating 725 children between 4 and 14 years of age, the selection was opportunistic recording in a database the socioeconomic status of the progenitors, the chronology and emergence sequence of each of the permanent teeth. Results: Regarding the socioeconomic status, 38.62% were Level I, 40.83% Level II, 15.86% Level III, 4.14% Level IV and 0.55% Level V. The first tooth to appear in the maxilla was the first molar (74.34-76.41%), while in the mandible it was the central incisor (78.9-82.76%) with statistically significant differences (p-χ2 <0,001). Conclusions: The medical care and nutrition of the patients will depend on the socioeconomic status, but at the dental level there were no statistically significant differences regarding the chronology and eruption sequence.
