‘Correlation of Transverse Facial Dimension in Vertical Facial Morphology- True Size Frontal Face Photographic Study’

Background: Dental photography in the recent times has become a forerunner in diagnosis and treatment planning due to its low cost and less technique sensitivity. The importance of clinical photography in orthodontics mainly focuses on facial esthetics. Materials and methods: In this cross sectional study,true size frontal face photograph was taken for 180 subjects of aged 17 to 30 years with different growth pattern which was defined by Jarabak ratio and GoGn to Sn angle in normodivergent,hypodivergent and hyperdivergent group. Various transverse facial dimensions were measured in adobe Photoshop software CS3 version 10. Results: Data was analyzed using SPSS version 23,One way ANOVA for Intergroup comparison showedIntercanthaldistance, outercanthal distance,intercommisural distance,intergonial distance,’N-Gn’( anterior facial height), Facial index and Bizygomatic width was highly significant (p <0.001) while internasal distance was statisticallysignificant (p≤ 0.047). post hoc LSD test showed that normodivergent growth pattern had no sexual dimorphism, hypo divergent growth pattern showed that males had greater internasal distance and females had greater intercanthal ,intercommisural distance which was statistically significant . In Hyperdivergent growth pattern , females had higher intercanthal, outercanthal, intercommisural, intergonial distance, males had greaterinternasal and facial index which was statistically significant whereas N’-Gn’ and bizygomatic width was nonsignificant among gender. Conclusion: Transverse facial dimensions in vertical facial morphology revealed thatHyperdivergent had more Outercanthal distance, intergonial distance, N’-Gn’ (Facial height), facial index and bizygomatic width. Normodivergent had more intercanthal distance and intercommisural distance. Hypodivergent had more internasal distance.Normodivergent growth pattern had no sexual dimorphism. Hypodivergentand hyperdivergent growth pattern had sexual dimorphism.
