Abstract

Context: Palatal rugae plays very important role in identification of individual. It is important dental evidence as it remains unchanged during lifetime. Palatal rugae are roof of hard palate on anterior portion. Studies have been done that no two palates are alike in their layout. Many factors, such as chemical treatments, heat, or disease do not effect on outline and shape of pattern. aims: To study of inheritance of palatal rugae pattern among two generation 60 dental casts were selected of father, mother and off springs. They are examined for any similarity and dissimilarity in palatal rugae pattern. Examination of rugae pattern was done according to Thomas and kotze classification. conclusion: No significant difference was seen in rugae pattern from father to offspring and mother to offspring. This study shows the percentage of inheritance on the basis of total number of rugae pattern in among from father to offspring is 30% and from mother to offspring is 25% and dissimilarities from father to offspring is 70% and mother to offspring is 75%. Palatal rugae are unique to every individual. Palatal rugae can be used as an ancillary tool in identification of individual in forensic science.
