Mucopolysaccharidosis: MPS VI and associated delayed tooth eruption.

Eight cases of mucopolysaccharidosis Type VI (Maroteaux-Lamy syndrome) are reviewed and two cases are presented in detail. Developmental dental anomalies including unerupted and impacted permanent teeth and associated hyperplastic tooth follicles are seen frequently in MPS patients. The surgical implications and management are discussed. All patients reviewed had significant cardiovalvular disease. It is essential for the primary medical provider to establish early basic dental care and evaluation for delayed eruption of primary and permanent dentition. This will probably minimize the possibility of infective endocarditis and allow for early treatment of impacted teeth.
