Abstract


Objective: To compare and correlate different skeletal patterns by using panoramic radiographs and lateral cephalograms.

Materials and Methods: Pretreatment panoramic radiographs (PR) and lateral cephalograms (LCR) of total 112 selected subjects in the age range of 10 to 15 years were obtained for analysis. Subjects were divided into three groups on the basis of SN-MP angle (Normodivergent=31–34 degree, Hypodivergent <31 degree, Hyperdivergent >34 degree). Subjects were statistically analyzed using ANOVA, Paired sample t-test and Karl Pearson’s Coefficient of Correlation test.

Results: All the parameters were higher in PR as compared with LCR (except AHMx and ML/RL) and significant correlation was found between linear and angular variables between two radiographs (highest for PHMn: Group I r=0.867** p=<0.0001***, Group II r=0.812** p=<0.0001***, Group III r=0.847** p=<0.0001*** among linear parameters and highest for ML/RL: Group I r=0.860** p=<0.0001***, Group II r=0.863** p=<0.0001***, Group III r=0.925** p=<0.0001*** among angular parameters).

Conclusion: For linear parameters, highly significant correlation was found for PHMn and for angular parameters for ML/RL.
