Cervical vertebrae maturation: a blinded trial study.

ABSTRACT

This blinded trial was conducted to analyze possible correlations between the cervical vertebrae maturation method (CVM) and the mineralization of mandibular teeth as described by Demirjian et al. (TMS). Panoramic and cephalometric radiographs of 500 orthodontic patients were analyzed by two blinded operators. TMS was utilized to analyze mineralization of second molar, second and first premolar and canine on the left side of the mandible; CVM stage was also evaluated. A blinded statistician performed statistical correlations and multiple regression analysis. Significant relations between CVM and TMS stages were identified for each tooth. Significant age differences resulted for CVM, second molar and second premolar (p<0.05). Significant correlations for second molar were observed between TMS D and CVM I-II, TMS G and CVM III, TMS H and CVM V-VI (p less than 0.01). Second molar stage G for both sexes indicates the ongoing of growth spurt. Stage G for boys and stage H for girls correlate significantly with the late part of PGS.
