Resumo
As vértebras cervicais vêm sendo cada vez mais empregadas para a análise de maturação óssea em Ortodontia e Ortopedia Funcional dos Maxilares. Visto que as mudanças que ocorrem nessas estruturas são sutis, comparou-se, por meio de medidas, sete razões obtidas nas vértebras cervicais C2, C3 e C4 em radiografias cefalométricas laterais entre as fases da curva de crescimento puberal de 95 pacientes do sexo feminino e 136 do masculino. Os resultados demonstraram que a razão 1 (C2Conc/C2PI-C2AI) difere estatisticamente entre os grupos A/B e C/D nos indivíduos do sexo masculino e entre B/C e D/E nos do feminino; a razão 2 (C3Conc/C3PI-C3AI) difere estatisticamente entre os grupos A/B/C/D nos indivíduos do sexo masculino e entre B/C e D/E nos do feminino; a razão 3 (C4Conc/C4PI-C4AI) difere estatisticamente entre os grupos B/C/D nos indivíduos do sexo masculino e entre B/C e D/E nos do feminino; a razão 4 (C3AS-C3AI/C3PS-C3PI) difere estatisticamente entre os grupos B/C nos indivíduos do sexo masculino e entre B/C/E nos do feminino; a razão 5 (Altura do corpo de C3/Comprimento do corpo de C3) difere estatisticamente entre os grupos A/C/D/E nos indivíduos do sexo masculino e entre A/C e D/E nos do feminino; a razão 6 (C4ASC4AI/ C4PS-C4PI) difere estatisticamente entre os grupos B/C nos indivíduos do sexo masculino e entre os grupos B/C/D nos do feminino; e a razão 7 (Altura do corpo de C4/Comprimento do corpo de C4) difere estatisticamente entre os grupos C/D nos indivíduos do sexo masculino e entre A/C/D nos do feminino.
The cervical vertebrae have been employed on the assessment of the bone maturation stage on the last years. Since the changes on these structures are subtle, seven ratios obtained from measurements on lateral cephalometric radiographs of the second, third and fourth cervical vertebrae were compared among the phases of the pubertal growth curve of 95 male and 136 female patients. The results demonstrated that ratio 1 (C2Conc/C2PI-C2AI) differs statistically between groups A/B and C/D on male subjects and between groups B/C and D/E on female subjects; ratio 2 (C3Conc/C3PI-C3AI) is statistically different among groups A/B/C/D on males and between B/C and D/E on females; ratio 3 (C4Conc/C4PI-C4AI) differs statistically among groups B/C/D on males and between B/C and D/E on females; ratio 4 (C3AS-C3AI/C3PS-C3PI) is statistically different between groups B/C on males and among B/C/E on females; ratio 5 (Height of the body of C3/Length of the body of C3) differs statistically among groups A/C/D/E on males and between A/C and D/E on females; ratio 6 (C4AS-C4AI/C4PS-C4PI) differs statistically between groups B/C on male subjects and among groups B/C/D on females; and ratio 7 (Height of the body of C4/Length of the body of C4) differs statistically between groups C/D on males and among A/C/D on females.
