“…The third molars were excluded because of uncertainty regarding the formation and the poor correlation with skeletal maturity [ 27 ]. Maxillary teeth were also excluded as their roots overlap with the calcified structures in this area, such as the zygomatic arch or the maxillary sinus or zygomatic process, which makes interpretation difficult [ 18 ]. Based on the apex closure [ 13 ], the teeth were rated accordingly from stage A to H.…”

“…The dental literature has no scarcity for research related to correlation between dental calcification stages and skeletal maturation stages. But these studies have the following shortcomings: (a) lack of sample size calculation [ 14 – 21 ], (b) very small sample size [ 17 ], (c) evaluation of maxillary teeth while they are superimposed by other structures [ 22 ], (d) wide age range (patient age greater than 16 years) [ 19 , 20 ], and (e) inclusion of teeth at the age where root formation either has not yet started or has already been completed [ 14 , 18 – 20 ]. A systematic review and meta-analysis [ 23 ] also pointed out methodology errors and high heterogeneity in the published on this topic research.…”

Introduction. The determination of skeletal maturity stages is very important in orthodontic treatment planning, especially skeletal discrepancies in growing individuals. A hand-wrist radiograph is considered the most accurate approach for skeletal maturity detection. Dental calcification stages have been suggested as an alternative diagnostic method to decrease radiation exposure. The recent study is aimed at detecting the efficacy of dental calcification stages in assessing skeletal maturity during the prepubertal and pubertal growth periods. Methods. Patients’ records were collected from the Aleppo Orthodontic Center. Dental maturity stages were assessed from a panoramic radiograph using the Demirjian method, while skeletal maturity stages were determined using the Björk method. Four permanent left mandibular teeth were included (canine, 1st premolar, 2nd premolar, and 2nd molar) for the study. Results. From 517 records, 295 records (145 males and 150 females) were included. The Spearman rank-order correlation coefficients between skeletal maturation and dental maturation were strong and statistically significant (ranging from 0.789 to 0.835). The highest correlation was between skeletal stages and the second molar ( r = 0.829 and 0.88 in males and females, respectively). Receiver operating characteristic (ROC ) curve suggested a high validity of the sum of dental stages for the four teeth in identifying MP3= stage (sensitivity was 70%, specificity was 92.77%, and ROC area was 0.81) but not for MP3cap (sensitivity was 50.85%, specificity was 81.36%, and ROC area was 0.66). Conclusions. The correlation between the skeletal maturity stages and the dental calcification stages was high. The orthodontist can use the dental stages as a definite diagnostic tool for prepubertal growth period.
