“…The sample size addressed in the present study (n=98) is similar to other studies in the field (Santos et al, 2005;Damian et al, 2006;Moraes et al, 2007;Lara et al, 2008). Moreover, the present study has the advantage of examining the age information retrieved from the teeth, cervical vertebrae and hand and wrist.…”

This study aims to perform age estimation using three different parameters from dental and skeletal development. The sample consisted of 98 dental records of patients aged from 10 to 16 years old, containing the chronological age and a set of radiographs (panoramic, lateral cephalometric and carpal radiographs) taken in the same day. The biological age was assessed through the dental development from panoramic radiographs according to the Nicodemo's method. The stages of dental development were registered and imported in CRONOL software (UNESP, São Paulo, Brazil), which provided the estimated dental age. The lateral cephalometric radiographs were analyzed to assess the development of the vertebrae C2, C3 and C4. And carpal radiographs were evaluated according to Fishman's method. Shapiro-Wilk test was used to verify the normality of the chronological and estimated age. T-test for unpaired samples was used to compare the normal data. Chi-square test was used to analyze the age in function of sex. Moderate and strong correlations were found between the chronological and biological (estimated) ages for all the methods. Statistically significant differences between the development of males and females were not observed (p>0.05). A linear regression formula was designed to allow age estimates statistically more accurate (p<0.0001). The formula reached an accuracy rate of 71.4%. In general, the methods underestimated the age. The combination of methods led to optimal performances for age estimation. The performances were similar between males and females.

“…Bone age, which is currently determined through radiographic images of the cervical vertebrae, 2,11,16,22 has historically been identified through hand-wrist radiographs. 4,7,12 The use of new diagnostic methods is certainly part of the evolution of science, but does not invalidate classic methods of proven reliability.…”

Aim: The purpose of the present study was to analyze the relationship between root formation of the first premolars and skeletal maturation stages identified in hand-wrist radiographs. Methods: A cross-sectional study was carried out involving the panoramic and hand-wrist radiographs obtained on the same date of 232 patients, 123 boys and 109 girls aged 4 years and 5 months to 17 years and 12 months. Root formation stages of the first premolars were related to the ossification stages of the sesamoid bone, epiphyseal stages of the phalanx of the thumb and epiphyseal stages of the radius. Results: The studied variables demonstrated statistically significant correlations. Conclusion: Roots of the lower first premolars do not reach 2/3 of their complete length before adolescence.

“…Many authors have attempted to determine the best indicators of the maturation degree. Secondary sex characteristics (5), chronological age (6), dental development (7,8), height (6), weight (6), skeletal development (9) and vertebrae development (10,11) are some of the parameters that have been used to identify the different growth phases. The bone age, also known as bone maturity age, has been the indicator most commonly used in studies on growth and development, and considered as a true record of the biological age.…”

“…Many authors (10,11,13,14) have accomplished studies on the cervical vertebrae development for the determination of the individual's skeletal maturation. Thence, the objective of this study was to compare two skeletal maturation indexes, the carpal index and the vertebral index, and verify the trustworthiness of the vertebral index for the determination of the skeletal maturation stages.…”

Purpose: The present work consists of a comparative study of two indexes of skeletal maturation: the carpal index (SMI) and the vertebral index (CVMI) and verification of the reliability of the vertebral index in the determination of the stages of the skeletal maturation.Methods: Radiographies from the dental records of treated patients from Universidade do Sul de Santa Catarina (UNISUL) were used. The sample was composed of 158 radiographies comprising seventy-nine carpal and seventy-nine lateral cephalometric radiographies of patients of both genders between six and eighteen of age. The carpal radiographies were analyzed using Martins' method and the lateral cephalometric, according to Baccetti, Franchi and McNamara Jr.Results: The Spearman's correlation test results showed a significant correlation coefficient of 0.616 between SMI and CVMI and the Pearson's test, of 0.698 for both genders (P<0.0001). The correlation between the indexes and the chronological age was 0.775 for SMI using Spearman's test, and 0.974 using Pearson's correlation test. For the CVMI, Spearman's correlation was 0.563 and Pearson's was 0.717, showing that there is a statistically significant correlation.Conclusion: The SMI is the safest and most trustworthy method to evaluate the skeletal maturation, although the CVMI can be used as a substitute method when there is conversance with the morphologic alterations of the vertebrae and when the carpal radiography is not available in the patient's orthodontic records.
