Introduction:  Chronological  age  alone  is  not  sufficient  for  assessing  the  developmental  stage  of  a 

growing child; hence, many skeletal maturity indicators have been proposed. Periapical radiography is the 

preferred imaging technique  in dental clinics and can be used as an alternative diagnostic tool for maturity 

prediction.  The  purpose  of  this  study  was  to  assess  the  correlation  between  modified  periapical  and 

cephalometric methods for predicting skeletal maturation in children.

Methods: Children who required a maturity analysis for orthodontic treatment planning were included in 

this study. Cephalometric radiographies were obtained from the clinics of orthodontics. The medial 

phalanges of the third finger (MP3) regions of 150 children (70 males, 80 females) between the ages of 8 

and 18 years (mean = 13.47±3.08) were imaged in pediatric dentistry clinics. For cephalometric and 

periapical images, maturity was assessed using Baccetti et al.’s, and Rajagopal and Kansal’s analyses, 

respectively. Spearman correlation coefficients were used to evaluate associations between skeletal stages 

with significance levels set at p<0.01 and <0.05.

Findings: There was a significant correlation between cervical vertebrae and MP3 analyses for all groups 

(p<0.001) with the exception of 10-year-old children (r=0.523, p>0.05).

Conclusion:  The MP3 method is a useful tool for the assessment of maturity in children as there is no 

need for special equipment and because of its relatively easy system for determining stages.
