Introduction: Nolla's method evaluates dental age in permanent teeth, classifying it on a scale from 0 to 10;
The objective of this study is to determine the chronological age and Nolla stages in the first permanent molars
through radiographic observation of pediatric dental patients treated at the Dental Clinics of San de Portoviejo
University, from January to December 2023.
Materials and methods: This study is observational, cross-sectional, and retrospective. A non-probabilistic
sample was selected for convenience, including 301 panoramic radiographs from ages 4 to 9 years. The
maturation stages were assigned to the first permanent molars according to Nolla's method of recording dental
age. The relationship between chronological age and the Nolla stage of dental mineralization was calculated
using a Pearson Chi-square test.
