Prevalence of facial asymmetry in tirupathi population-a postero anterior cephalometric and photographic study

Abstract

Aims & Objective: The human face is the most prominent aspect in human social interactions, and therefore it seems reasonable coming for orthodontic treatment is to overcome psycho-social difficulties relating to facial and dental appearance and enhance the quality of life in doing so. Methods: Postero anterior cephalograms and frontal photographs of 100 subjects (50 males and 50 females) were analyzed to evaluate skeletal asymmetry by the analysis suggested by Grummons(1987) and soft tissue facial asymmetry by using composite photographic analysis. The data were statistically analyzed using the SPSS 16.0 programme statistical analysis package software. Independent t-test was used to find the differences between different measurements. Results: All subjects showed mild asymmetry and right-sided laterality. The difference between the right and left sides were statistically insignificant (‘p’ > 0.01). The test revealed that only Co distance was statistically significant (‘p’< 0.01).and all other values are not statistically significant. Conclusion: Composite photographs of hundred subjects revealed that facedness is towards right but this laterality was not statistically significant. Both posteroanterior cephalograms and composite photographs showed right-sided laterality. Gender difference in both skeletal and soft tissue asymmetry is not statistically significant.
