Correlation between Cephalometric and Facial Photographic Measurements of Craniofacial Form-A Cross Sectional Study

Aim: This study aims at evaluating relationship between craniofacial measurements obtained from cephalometric radiographs and analogous measurements from standardized facial photographs. Material Method: Lateral cephalograms and standardized profile photographs were obtained from 60 subjects (age 18 – 30 years). Digital cephalograms were analyzed with software NemoCeph and photographs were analyzed using adobe Photoshop. The following vertical measurements were studied Ar-Go-Me, FMA, OPA, AFH (N-Me), LAFH (ANS-Me), PFH(S-Go), LPFH (Ar- Go) and Sagittal assessment include Wits, ANB, FNP, N-ANS-Pog. Result: There was no significant difference seen in N-Sn-Pog' on photographic analysis p=0.511, OPA', p=0.054. Measurements. Other measurements showed significant differences (p<0.0001). Moderately positive and good significant correlation were found for ANB and Wits (r.>0.6, p<0.05). Conclusion: The reliability of using photographs is established indicating that the facial landmarks can be located consistently on a photograph. ANB' and Wits' measurements were the photographic variables that moderately explained the variability of its analogous cephalometric measurement
