Description
Summary:The frequency of missing third molars is about eight per cent per quadrant in a sample of 490 males of the mixed White/Negro/Indian population of Natal, Brazil. Absence of the four third molars appears in two per cent of the individuals of the sample. The degree of asymmetry for the trait was not marked. No differences were observed when the persons were separated on morphological grounds as Whites or Negroids suggesting that these segregants may be genetically homogeneous in relation to this and other characteristics.
