Introduction:

Tooth eruption is a physiological process that can be altered by multiple congenital or environmental causes.

Objective:

To determine the chronology of permanent dental eruption and its relationship with influencing factors in 13-year-old adolescents from the Sancti Spíritus municipality.

Methods:

A cross-sectional descriptive study was carried out in the Sancti Spíritus municipality from September 2017 to June 2019. The population consisted of 1 355 13-year-old adolescents belonging to all the urban basic secondary schools of this municipality and by stratified sampling in two stages. A sample of 406 adolescents was selected. Theoretical, empirical and statistical-mathematical level methods were used.

Results:

It was found that 22.9% of the adolescents presented delayed dental eruption chronology with respect to the Mayoral measures, with a predominance of males (57%) and the Europoid ethnic group (83.9%). The factors that most influenced were the retention of temporary teeth with 72%, sex with 57% and hereditary history with 49.5%, the three variables with great statistical significance.

Conclusions:

Almost a quarter of the 13-year-old adolescents studied in the municipality of Sancti Spíritus presents a delay in the chronology of permanent dental eruption with respect to the Mayoral values. Those of the masculine sex presented double the risk for a delayed chronology and there were no differences regarding the ethnic group. The factors that most influenced were heredity, sex and retention of temporary teeth.
