“…Formerly, several studies reported no significant difference between the developmental stages of teeth 38 and 48 (Soheim, 1993;Stavrianos et al, 2008;Mohammed et al, 2014). Our results also found no significant difference between teeth 38 and 48 because teeth 38 and 48 do not differ in development.…”

The aim of this study was to test the accuracy of an age estimation method using the radiographs of permanent mandibular third molar teeth in a Southern Thai population. Digital panoramic radiographs of 480 Thai samples (240 males and 240 females) aged from 8 to 23 years were selected and divided into 16 age groups. The permanent mandibular third molar teeth were separated into nine developmental stages according to the Demirjian et al. classification. The developmental stage was evaluated and then converted into a developmental score. Accuracy of the dental age estimation was tested using regression equations according to the Duangto et al. study. Our results showed that dental age was close to the chronological age within one year for both sexes. In conclusion, the age estimation equations according to the Duangto et al. study provide an accurate age estimation in a Southern Thai population.

“…For males, only SMI 1 and 4 that their results showed 1.2 and 1.35 years lower mean age. In others hand, for the rest SMIs, their results showed higher mean chronological ages (Mohammed et al, 2014b). In general, their subjects showed relatively delayed skeletal maturity while this present study showed around 1 year advanced skeletal maturity (Table 17).…”

Introduction: Age estimation takes part in a variety of situations, such as growth observation, immigrant registration, legal penalty judgment and body identification. Chronological age usually corresponds with stages of skeletal and dental development. Age estimation by using hand and wrist radiography is the first method of choice for many cases because it is uncomplicated, inexpensive and non-invasive. However, the validity of the result is still questionable mainly because of the influence of ethnic differences. Objectives: The primary aim of this study was to evaluate the accuracy and reliability of the commonly used age estimation methods on Thai population. The secondary aims were to compare the results between different methods and to find any possible relationship on Thai population. Materials and methods: Hand and wrist radiographs from the Department of Radiology, Faculty of Dentistry, Chulalongkorn University were collected. The radiographs were taken between 2011 – 2016 and the patients must not have history of diseases that affect skeletal development. ‘Greulich and Pyle’, ‘Tanner and Whitehouse (TW3-RUS)’, and ‘Fishman’ method were applied for each radiograph. The results from each method and the chronological age were compared using Friedman’s rank test (p<0.05) followed by a Wilcoxon signed ranks test with Bonferroni correction. Results and Discussion: The estimated ages from the three methods were significantly different from the chronological age (p<0.002), except for ‘Tanner and Whitehouse’ in male which showed no significant difference. Overall, the results from each method tended to be overestimated although the tendency of underestimation was found particularly in younger groups. The presence of discordance supported the influence of ethnical factor and secular change on skeletal maturation rate. Conclusions: Tanner and Whitehouse TW3-RUS method was more accurate in predicting the age of contemporary Thais; however, a further adaptation of the method to reduce the discrepancies in late teenagers is recommended.

“…The growth spurt stage during or before adolescence has a significant impact on both orthodontic planning and the retention of results after orthodontic treatment [ 9 ]. Observation of changes in the size and shape of the hand and elbow bones on radiographs can be used to identify bone growth, bone formation, and its early manifestations of maturation [ 10 ]. Assessment of bone ossification using a hand-wrist radiograph is traditionally considered a reliable indicator of maturation [ 11 , 12 ].…”

Aim This study aims to investigate the relationship between the frontal sinus index and different stages of cervical vertebral maturation and to determine whether these measurements can be used as accurate markers for evaluating skeletal maturity. Materials and methods The sample size was 120 subjects, with ages that ranged from 8 to 25 years. Standardized pretreatment digital lateral cephalograms were analyzed. Six groups representing different phases of cervical vertebral maturation were created from the entire sample. Each group had 20 subjects and was split into male and female groups. On the same radiograph, the cervical stages were assessed and the frontal sinus index was calculated. Correlations between the frontal sinus index and cervical vertebral maturation were assessed using statistical analysis. Results Sinus index values, which assess the ratio of frontal sinus dimensions to cervical stages, were found to be comparable between the two adjacent cervical stages. However, the patterns of sinus index values differed between males and females, suggesting potential variations in sinus development between the sexes. Conclusion Frontal sinus height and width were significantly correlated with cervical vertebral maturation stages in both sexes. The frontal sinus index, on the other hand, was not significant.
