Parental consanguinity a possible risk factor for tooth agenesis: A case series

Abstract

Dental agenesis is a commonly encountered dental anomaly that affects more than 20% of the human population. It can be categorized as hypodontia, oligodontia, or anodontia. Oligodontia can occur either as an isolated finding or as a part of the syndrome, and the causative factor can be either environmental or genetic.: This report describes three cases of isolated, non-syndromic tooth agenesis with single/ multiple missing permanent teeth. No other associated clinical features or any systemic involvement were present in these cases, suggesting parental consanguinity as a possible etiological factor.: The purpose of this case report is to promulgate premarital counselling and health awareness programs focusing on the potential consequences of consanguineous marriages and their prevention.
