    Author: Ercan DE, Yüksel S.
    Journal: Am J Hum Biol; 2023 Dec; 35(12):e23957. PubMed ID: 37409622.
    Abstract:
    OBJECTIVES: The aims of this study were to determine the skeletal, dental, and sexual maturation stages of individuals at the peak of the pubertal growth spurt and to analyze the correlations between these parameters. METHODS: The study included 98 patients, 49 females (mean chronological age 12.05 ± 0.96 years) and 49 males (mean chronological age: 13.18 ± 0.86 years), in the MP3cap stage. Skeletal maturation stages were determined using the cervical vertebral maturation (CVM) method on lateral cephalometric radiographs. The Demirjian index was used to determine dental maturation stages and dental ages on panoramic radiographs. The sexual maturation of the patients was evaluated in the pediatric endocrinology clinic by a pediatrician according to the Tanner stages. The frequencies of the variables were determined, and the Spearman rank correlation coefficients were used to analyze the correlations between the variables. RESULTS: It was determined that the cervical vertebral maturation stage was CS3 in 81.6% (n = 40) of both female and male patients, and 81.6% of the female and 89.8% of the male patients were in stage G in terms of mandibular second molar tooth development. According to the Tanner pubic hair staging, 73.5% of the male and 51.0% of the female patients were in Stage 3. A significant correlation was found between the cervical vertebra stages and mandibular second molar tooth development stages in both sexes and between the cervical vertebra and Tanner pubic hair stages only among the male patients (r = 0.357; p < .05). There was also a significant and strong correlation between the Tanner pubic hair stages and breast development stages (r = 0.715; p < .05). CONCLUSION: Cervical vertebral development in the CS3 stage and mandibular molar tooth development in the G stage can be considered the peak of the pubertal growth spurt. Tanner Stage 3 marks the peak of the pubertal growth spurt in males.
