Taurodontism in Brazilian patients with tooth agenesis and first and second-degree relatives: A case-control study

Taurodontism is more frequent in nonsyndromic familial tooth agenesis. Individuals in families with second premolar and molar oligodontia are more likely to have taurodontism, even the individuals with complete dentition. This association could define a subphenotype for future genetic studies of dental development.
