Correlation between Dental Calcification Stage 5 and CVM Stage 3 in Class II Malocclusion Patients

Abstract

Introduction: Growth modification treatment using functional appliances is recommended for growing patients. For the best outcome, it is necessary to use the functional appliance at the peak puberty. The goal of our study was to determine whether a correlation exists between calcification stage 5 of the mandibular 2nd molar and maxillary canine and the CVM stage 3 to assess the timing of skeletal maturation from an Orthopantomogram (OPG) radiograph.

Material and Methods: The sample size comprised 100 patients, 71 females and 29 males aged 11 to 15 years. The maxillary canine and the mandibular 2nd molar teeth calcification stage (stage 5) were determined by the modified Gleiser and Hunt method on Panoramic radiographs. The peak pubertal growth stage (CVM 3) was assessed by the CVM method on Lateral cephalometric radiographs.

Results: CVM stage 3 and canine calcification stage 5 were not correlated whereas canine calcification stage 5 and molar stage 5 were significantly correlated with p-value <0.05. Moreover, CVM stage 3 and molar stage 5 were also not correlated.

Conclusions: Assessment of dental calcification stage five of the maxillary canine and mandibular 2nd molar on the panoramic radiograph can not be used to assess the timing of skeletal maturation. A larger sample size is required to verify the reliability of this method.
