Abstract
Background: Tooth eruption is the movement of teeth through the bone and overlying mucosa to emerge and function in the oral cavity. Aim: To characterize the variability in the sequence and chronology of eruption of the permanent dentition in children aged 5 to 12 years. Method: A descriptive observational cross-sectional study was carried out in the "Briones Montoto" Primary School of the municipality of Guanabacoa, in the period between September 2019 and June 2020. The universe was constituted by 239 children and to determine the chronology of dental eruption, a sample of 216 children who attended classes on the day of the evaluation were taken, who fulfilled the inclusion and exclusion criteria. Results: At 5 years of age, most of the children were found with their primary dentition completed, representing 61.5%, at 6 years of age 85.5% presented all the incisors plus the first molar and 57.1% of the total studied at the age of 11 years had all the permanent teeth up to the second molar, with a predominance of the female sex, which represented 66.7%. Conclusions: There is an advance in the sequence and chronology of permanent dental eruption in this school, becoming more evident in the female sex with the central incisor being the first tooth to erupt before the first molar.
