Photographic evaluation is a very close representation of the appearance of the person, especially in Orthodontics. With the advent of cephalometrics, the emphasis shifted to the assessment of bony foundation of the face and positions of teeth. However, it was soon realized that the correction of hard tissues to the normal values need not always bring about an improvement in the facial appearance. The aim of this study is to investigate the relationship between craniofacial measurements obtained from cephalometric radiographs and analogous measurements from profile photographs in skeletal class I subjects. Lateral cephalograms and standardized facial profile photographs were obtained from a sample of 35 skeletal class I subjects. Angular and linear measurements were done using FACAD Software at Saveetha Dental College , Chennai. Statistical tests were done using SPSS Software. The statistical tests done were Pearson’s correlation test and linear regression . On comparing the angular and linear cephalometric and photographic measurements, significantly high correlation was found. The study was found to be statistically significant with P value <0.001. The FMA value showed the highest correlation. The photographic method of measuring cephalometric values has been found to be a highly significant and reliable tool, provided standardized protocol is followed. Hence, it may be considered a feasible and practical diagnostic alternative , particularly if there is a need for a low-cost and non-invasive method.
