The Correlation between Dental Stages and Skeletal Maturity Stages

Abstract

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.

Skeletal maturation evaluation: which is the reliability of dental calcification Demirjian method versus hand-wrist X-ray in growing subjects? A systematic review

“…for title and abstract. Out of these, we included 25 papers for full-text screening [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. Six articles not respecting eligibility criteria were excluded by the systematic review.…”

Skeletal, dental, and sexual maturation as an indicator of pubertal growth spurt

“…According to Günen Yılmaz et al (2019) tooth calcification stages of mandibular second premolars showed the highest positive correlation with skeletal maturation stages. In a study evaluating skeletal and dental maturation (Jourieh et al, 2021), it was determined that 76.66% of girls and 86.66% of boys at the MP3cap stage had mandibular second molars at the G stage. In our study, the number of individuals with mandibular second molar teeth in the G stage was higher compared to the other stages, and there was a significant but low correlation between the cervical vertebra and mandibular second molar tooth development stages in both sexes.…”

Correlation between Mandibular 2nd Molar Calcification Stages and CVMI among Southern Punjab Population

“…6 Multitudinous studies have been conducted to evaluate correlation between different skeletal age predictors. [7][8][9][10][11][12][13][14][15][16][17] The results vary from population to population thereby escalating the need for more research in individual populations. The current study was carried out to explicate the association between the lower second molar calcification stages and cervical vertebral maturation stages in patients of Southern Punjab population of Pakistan.…”
