Abstract
Introduction: Photographic analysis has been considered as an essential tool for orthodontic diagnosis and treatment planning, lending to its cost effective and non-hazardous nature. It is imperative to assess the hard and soft tissue relationships in order to evaluate if photographs can be used as an alternative to radiographic analysis. The aim of this study was to investigate the interrelationship of cephalometric hard tissue measurements with their soft tissue counterparts in individuals with different skeletal patterns.
Materials and Method: Lateral cephalograms and standardized photographic records were obtained for 150 subjects (79 girls, 71 boys, 9-16 years) which were divided into three groups of Class I, II and III skeletal jaw bases. Analogous photographic and cephalometric values were compared to evaluate Peason’s correlation coefficients. Correlations were compared to evaluate the influence of skeletal pattern as well as sexual dimorphism on hard and soft tissue relationships.
Results: Strong correlation was observed amongst most measurements. Sexual dimorphism was prominent in photographic variables. Amongst all three groups combined, the photographic variable that was most analogous with its cephalometric variable was N’perp-A’(r = 0.988) and N’perp-Pog’ (r = 0.988) and least analogous was LAFH’/AFH’ (r = 0.416).
Conclusion: Photographic method is a reliable and repeatable alternative to cephalometric technique, irrespective of one’s gender or skeletal pattern. Anteroposterior jaw discrepancy can be analysed with soft tissue photographs more efficiently as compared to vertical discrepancies
