Abstract
The present study was conducted on 294 males and 306 females from outpatients reporting to J.K.K. Nattraja Dental college, Komarapalayam, Namakkal. The skeletal maturation was assessed using Hand wrist radiograph using the method proposed by Grave and Brown classifying the ossification into fourteen events and three stages. Dental maturation stages were analysed from Orthopantamogram(OPG) using the method proposed by Demirjian et al in which maturation is classified into eight stages from A-H. The data was subjected to statistical analysis, and the following conclusions were drawn from the results. In males, mandibular canine and mandibular second molar were statistically significant with higher correlation observed in relation to stage F for onset of pubertal growth period, stage G coincided for peak of the pubertal growth period and stage H coincided for end of the pubertal growth period. In females, mandibular canine and mandibular first premolar were statistically significant 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 and stage H coincided with the end of the pubertal growth period. There is a correlation between dental maturation and skeletal maturation stages in determining the pubertal growth period. On comparison of chronological age the females preceded males in all three stages of skeletal maturation by approximately 1.6 years.
