Determinate the maximum peak of pubertal mandibular growth in a peruvian population through of chronological age and the cervical vertebrae maturation in patients between 8 to16 years of age, who received treatment in the Clinica Dental Docente UPC (Peruvian University of Applied Science), between 2011 - 2013.Materials and Methods: The study was observational, descriptive, cross-sectional, retrospective and used 137 cephalometric digital radiographs obtained from the data base program: SMILE® used in the Dental Clinic of UPC. These digital radiographs were of patients between 8-16 years, who attended the Dental Clinic for dental treatment, and were evaluated with the Method of Vertebral Cervical Maturation proposed by T. Baccetti in 2005. This method analysis the morphological characteristics of the bodies of the second, third and fourth cervical vertebra to determine the peak in mandibular growth. This method classifies six maturational stages, T1-T6. The digital cephalograms were analyzed by two calibrated examiners (Kappa = 0.7). Results: Statistical analysis (Kruskal Wallis, p < 0.05) was conducted to evaluate the relationship between the chronological age and the appearance of the cervical vertebral maturation stage 3 and 4 to determining the peak of pubertal mandibular growth. In girls, the peak of mandibular growth occurred at the age 10.48 and in boys this occurred at the age of 11.21 Conclusions: The peak of pubertal mandibular growth occurred earlier in girls (10.48 years) than in boys (11.21years), having a difference of approximately one year between the two sexes.
