Online published on 17 February, 2020. Abstract Malocclusion may be defined as a mal-relationship of the dental arches beyond the range of what is accepted as normal. The adolescent growth spurt is a period of sudden increase in skeletal growth of the body and the face and thus any Dentofacial intervention during that period helps achieve more skeletal effects and stable treatment results. This study was aimed at determining the growth potential of the patient by investigating the relationship between the stages of calcification of mandibular 2nd molar and skeletal maturity stages among 8–13 years old children. 2. To correlate chronological and dental ages with skeletal maturity. A retrospective and cross-sectional in vitro study was carried out using the traditional films of pre-treatment OPGs and lateral cephalograms of 150 subjects (75 males and 75 females) visiting the department of Pediatric & preventive dentistry. Skeletal maturity was assessed on the lateral cephalograms using CVMI method described by Hassel & Farman. The permanent second molar calcification stages were assessed according to Demirijan index (DI) proposed by Demirjian et al. Females were found to be more advanced than males in both dental and skeletal maturation, being in accordance with previous reports. Each DI stage of mandibular second molar appeared at an earlier age in the females than males, which shows that dental maturation occurrs earlier in girls than boys by almost a year and completes earlier too, concluding thereby that interceptive orthodontic treatment should be initiated earlier in girls in order to harness the adolescent growth spurt to maximize the potential for effective interceptive orthodontic treatment.
