Relationship between Dental Development and Cervical Vertebrae Development Assessed Using Radiography in an Iranian Population

Abstract

Introduction:Determining the skeletal age and remaining growth potential of patients are important factors in orthodontic treatment. Evaluating cervical vertebrae development is a reliable method for determining skeletal age. This study aimed to evaluate the correlation between dental calcification and stages of skeletal maturation. Materials and methods:This descriptive cross-sectional study was conducted on 84 panoramic radiographs and lateral cephalometrics related to 10-15-year-old patients without systematic diseases affecting dental calcification and development. Patient's skeletal age was determined by the stage of cervical vertebrae development and by using Lamparski's method. Dental age of samples was determined by Demirjian's method. Findings were analyzed by SPSS 18 software using Spearman's correlation test to determine the correlation between the cervical vertebrae development and the dental development stages. P < 0.05 was considered significant. Results:Spearman's correlation test showed a significant direct correlation between dental age and skeletal age (r2 = 42.5%). The linear relationship between dental age and skeletal age was significant (p < 0.05). The highest correlation coefficient was between the cervical vertebrae development and the stages of mandibular second premolar calcification in girls (rs = 0.609) and in the second molar in boys (rs = 0.471). In Demirjian's method, stage G of the mandibular second premolar teeth in girls and stage F of the mandibular second molar teeth in boys nearly coincided with the pubertal growth spurt. Conclusion:The findings of this study showed that, in Demirjian's method, stage G of the mandibular second premolar teeth in girls and stage F of the mandibular second molar teeth in boys was most frequent between developmental stages. According to the relatively high correlation coefficient between the dental age and the skeletal age, using dental calcification stages by panoramic radiography may become a simple first-level diagnostic test to determine skeletal maturity, which requires more studies in different ethnicities and places all around the world.

Growth assessment among northern Nigerian children using the middle phalanx of the third finger and its correlation with mandibular canine calcification.

“…Also, dental calcification is considered to follow an independent process that is less affected by dental arch space, 15 deciduous teeth extraction, and dental eruption . In addition, to reduce radiation exposure when evaluating skeletal maturity, researchers have attempted to correlate dental calcification stages with cervical vertebrae and hand-wrist bone maturation stages among different [16][17][18] populations . Chertkow had earlier suggested using lower canines to predict pubertal growth spurt due to the high level of correlation with the hand and wrist bones 19 ossification stages .…”

Reliability of Mandibular Canine Maturation Stages in Predicting Pubertal Growth Spurt in a Sample of Egyptian Orthodontic Patients

“…Some studies have shown a strong correlation between calcification stages of various mandibular teeth particularly the mandibular canine and the skeletal maturity [30][31][32][33][34][35][36][37][38][39][40][41][42][43] , while others have refuted this claim [44][45][46][47][48] . Because of this controversy and the well-established racial variation in the stages of dental calcification 30,33,42,[49][50][51] , the present study was undertaken to investigate the reliability of mandibular canine maturation stages in predicting pubertal growth spurt in a sample of Egyptian orthodontic patients.…”
