ABSTRACT

Introduction: Face prediction based on genetic profiling, if feasible, may revolutionize forensics and strongly benefit medical diagnosis. A better understanding of the relative genetic influence on dento-facial and occlusal parameters would improve our knowledge of the etiology of orthodontic disorders, possibilities and limitations of orthodontic treatment and treatment planning. Aims and objectives: The purpose of this study is to investigate the heritability of soft tissue pattern between parents and their offspring both frontal and lateral photographic analysis based on correlation between measurements of areas and distance between features of parents and offspring. Material and methods: standard photographs taken in frontal and lateral photographs in an natural head position 120 subjects were taken from 30 families from Gulbarga population. tracing was done of the true life size measurements were obtained and correlation between parent –offspring group were analyzed. Statistical analysis was done by applying student t test. Results: results indicate that there lies a high correlation between mother and daughter and father and son group with some parameters being moderately correlated in opposite sex group. Daughter being affected by both the parents with strong correlation found in mother-offspring group. Conclusion: This study gave an indication regarding the fair genetic control in the transmission of soft tissue facial characteristics and consideration of the same can be done in prediction of growth and treatment planning in orthodontic practice in future.
