Abstract
Despite recent advances revealing genetic factors influencing caries susceptibility, questions regarding the model of inheritance involved are yet to be addressed. We conducted a Complex Segregation Analysis on decayed teeth in a sample of homogenous, isolated families recruited from the Brazilian Amazon. A dominant, major gene effect controlling resistance to phenotype was detected. The frequency of the resistance allele "A" was 0.63; mean numbers of decayed teeth were 1.53 and 9.53 for genotypes AA/AB and BB, respectively. These results represent a step toward a description of the exact nature of the genetic risk factors controlling human susceptibility to caries.Entities:
