A COMPARATIVE EVALUATION OF DENTAL CALCIFICATION STAGES AND SKELETAL MATURITY INDICATORS DURING THE PUBERTAL GROWTH PERIOD

Abstract

Aim:
To compare the dental mineralization stages using Orthopantamogram (OPG) and skeletal maturation stagesusing Hand wrist radiographs during the pubertal growth period. Material and Methods: The present study was conducted on 60 males and 60 females in Department of Orthodontics , Jaipur Dental College,Jaipur (Rajasthan) India. A total of 120 dental panoramic radiographs and hand-wrist radiographs were obtained and analyzed.The skeletal maturation was assessed using Hand wrist radiograph using the method proposed by Grave and Brown method. Dental maturation stages were analysed from Orthopantamogram (OPG) using the method proposed by Demirjian et al.
Results:
The results showed differences between the sexes of the sample (P <0.05) and between the skeletal maturation periods.In males, mandibular canine and mandibular second molar were statistically significant (P<0.05) with higher correlation observed in relation to Stage F for onset of pubertal growth , Stage G coincided for peak of the pubertal growth period ,Stage H coincided for end of the pubertal growth period In females, mandibular canine and mandibular first premolar were statistically significant (p<0.05 )and higher correlation was observed in relation to stage F for the onset of pubertal growth period, Stage G coincided with the peak of the pubertal growth period ,Stage H coincided with the end of the pubertal growth period.
Conclusion:
There is a correlation between dental maturation and Skeletal maturation stages in determining the pubertal growth period. Dental mineralization stages studied from Orthopantamogram(OPG) can be used as a routine diagnostic tool to determine the skeletal
maturation of the individual. On comparison of chronological age the females preceded males in all three stages of skeletal maturation by approximately 1.6 years
