Assessment of correlation between dental calcification stages and skeletal maturity indicators

Assessment of age is a critical step in the identification of an individual in forensic cases. The hand-wrist radiographic evaluation and tooth development is also a useful measure of maturity because it represents a series of recognizable changes that occur in the same sequence from an initial event to a constant end point.

To investigate the relationship of dental calcification stages and skeletal maturity indicators as assessed by the hand-wrist bone radiograph.

A cross-sectional pilot study was performed using orthopantomograph (OPG) and hand-wrist radiographs of fifty children (25 males and 25 females) with age ranging from 8 to 14 years. The hand-wrist radiographs and OPG were analyzed using Fishman's Skeletal Maturity Index and the Demirjian's system, respectively. SPSS software version 19 (IBM) was used in the calculation of all statistical analyses.

Correlation coefficient ranged from 0.61 to 0.83 for males and from 0.81 to 0.86 for females. The canine stage F for both sexes coincided with the MP3 stage, which is indicative of the onset of a period of accelerating growth.

The findings of this pilot study indicated that tooth calcification stages might be clinically used as a maturity indicator of the pubertal growth period.
