Dental considerations for patients with Hunter syndrome

Hunter syndrome, or mucopolysaccharidosis type II, is a rare X-linked disorder caused by a deficiency in the lysosomal enzyme iduronate-2-sulfatase. This results in accumulation of glycosaminoglycans (GAGs) in the lysosomes of various tissues. It causes physical and mental degeneration, in severe cases, death during the teenage years. Dental complications include enamel hypoplasia, microdontia, dentigerous cyst-like follicles, unerupted dentition, malocclusions, gingival hyperplasia, macroglossia, and condylar defects.
