Análise da calcificação de caninos inferiores esquerdos em panorâmicas na identificação da maturidade esquelética de indivíduos do gênero feminino

Abstract

Panoramic radiography is a technique used routinely among dental surgeons, including the possibility of contributing to the identification, through studies performed in this regard. The aim of this study was to analyze, by means of panoramic radiographs, the correlation with the skeletal age of the left lower canines of the female canines in the dental calcification stage, verified in hand and wrist radiographs. A sample of 52 female patient files, aged 9 to 15 years, from the Brazilian Association of Dentistry - Paraíba, was used, in which 52 panoramic radiographs were evaluated through the evaluation of the Nolla (1960) stages of the canine lower left and 52 hand and wrist radiographs, using the method of Greulich and Pyle (1959). When correlating bone age and Nolla stages, correlation coefficient = 0.6138, p≤0.0001 (Spearman's correlation) was obtained, while when correlating bone age (in months) and chronological age, the Pearson correlation coefficient correlation = 0.7189, p≤0.0001), according to the Kolgomorov-Sminov test. Of the sample presented, the girls with stage 7 of Nolla in element 33 were the only ones that had not yet reached the initial bone age to the pubertal growth spurt. We conclude that there is a positive correlation between bone age and Nolla stages, suggesting that this parameter should be better studied to confirm its accuracy.
