To account the cumulative effects of genes on dental caries between the sexes and to assess the heritability of midline diastema, melanin pigmentation, frenal attachment and tongue tie in family trees. A descriptive study was conducted among 100 families selected conveniently from Udham Singh Nagar, Uttrakhand. Pre structured performa was drafted to record demographic data and clinical examination of dental caries, frenal attachment, melanin pigmentation, midline diastema and tongue tie. Findings was compared within the pairs: grandparents- grandchildren pair and parent-offspring pair, to access heritability. Among grandfather-grandchildren pairs 36.76% had dental caries when compared with grandmother was 33.72%. Grandparent pairing with granddaughter had higher prevalence as compared to their pairing with grandson. Similar result was seen in parents-offspring pair. While it was vice versa in case of melanin pigmentation and no differences in its prevalence was seen in son and daughter pairs. In midline diastema, was higher in father son pair. Types of Frenal attachment was found to be statistically significant within all pairs and tongue tie was found clinically acceptable for all individuals.1 Genetics influence should be considered, in efforts to understand the multi-factorial nature of the diseases and can act as a vital tool in the easy diagnosis and prevention of these diseases.
