amelogenesis imperfecta with taurodontism, microdontia, and minor thalassemia: a case report

Amelogenesis imperfecta is a group of genetic disorders that affects both the morphology and quality of tooth structure. although the disease entity is primarily associated with abnormalities of dental and oral structures, it has been reported to be associated with a few syndromes. a 9yearold girl with minor thalassemia referred to the department of pediatric dentistry of the mashhad faculty of dentistry with a complaint of sensitivity of first permanent molars. dental findings consisted of amelogenesis imperfecta, microdontia, posterior cross bite and taurodontism. this is the first report of thalassemia accompanied with amelogenesis imperfecta. although the patients often are nonsymptomatic, the trait can be passed on to a child and if both parents carry the trait, the child could develop a more severe form of the disease; therefore, early diagnosis is important.
