Abstract

ABSTRACTObjective: the objective of the study was to determine the relationship between dental calcification stages and skeletal maturation in a Peruvian sample. Methods: panoramic, cephalometric and carpal radiographs of 78 patients (34 girls and 44 boys) between 7 and 17 years old (9.90 ± 2.5 years) were evaluated. Stages of tooth calcification of the mandibular canine, first premolar, second premolar, and second molar and the skeletal maturation with a hand-wrist and a cervical vertebrae method were assessed. The relationships between the stages were assessed using Spearman’s correlation coefficient. Additionally, the associations of mandibular and pubertal growth peak stages with tooth calcification were evaluated by Fisher’s exact test. Results: all teeth showed positive and statistically significant correlations, the highest correlation was between the mandibular second molar calcification stages with hand-wrist maturation stages (r = 0.758, p < 0.001) and with vertebrae cervical maturation stages (r = 0.605, p < 0.001). The pubertal growth spurt was found in the G stage of calcification of the second mandibular molar, and the mandibular growth peak was found in the F stage of calcification of the second molar. Conclusion: there was a positive relationship between dental calcification stages and skeletal maturation stages by hand-wrist and cervical vertebrae methods in the sample studied. Dental calcification stages of the second mandibular molar showed the highest positive correlation with the hand-wrist and cervical vertebrae stages.

Highlights

The optimal effectiveness of using braces or orthopedics has been associated with skeletal maturation
The growth of the bones of the hand and wrist has been used to assess skeletal maturation,[3,7,8,9] The method described by Fishman[3,10] seems to be the most appropriate method for assessing skeletal maturation.[11]. It considers eleven indicators of skeletal maturation, which cover the entire period of development. This method involves exposing the patient to additional radiographic imaging sessions, which is why several researchers[12,13,14] have developed indexes of skeletal maturation using the profile of cervical vertebrae bodies that appear on lateral radiographs of the skull, which are routinely used for diagnosis in orthodontics

The reproducibility was considered to be poor,[19,20] more recently, visual assessment of the stages with this method has shown acceptable reproducibility and accuracy.[21]
