Introduction:

dental eruption is a biological phenomenon related to the growth and development of the child, which generally presents a constant sequence.

Objective:

to characterize the rhythm of tooth eruption of different dental groups in permanent dentition according to weight and height.

Methods:

an epidemiological, descriptive, longitudinal and prospective study was conducted in children belonging to Vietnam Heroico School, in Santa Clara, from March 2016 to February 2017. The universe of study was 506 children, of both genders, between 5 and 13 years of age, with a final sample of 142 individuals.

Results:

weighted mean values of the monthly rhythm of tooth eruption were obtained for each dental group; which were related to the weight / age, height / age and weight / height percentiles. There was a slower rhythm of dental eruption in children with short stature, thin and malnourished, as well as in the obese ones. Those with tall or excessive stature, or overweight, had a faster rhythm of dental eruption.

Conclusions:

we concluded that the rhythm of dental eruption was mainly related to weight and height variables according to age.
