Relationship Between Occlusal Features and Enzyme Replacement Therapy in Patients With Mucopolysaccharidoses.

Purpose: The aim of this study was to describe the relation between occlusal features and enzyme replacement therapy in patients with mucopolysaccharidoses.

Materials And Methods: A cross-sectional study was conducted. The sample consisted of 20 patients with mucopolysaccharidoses, 10 of whom were undergoing treatment at a hospital in northeast Brazil. Occlusal features were evaluated by clinical examination and panoramic radiography. A structured questionnaire was administered to evaluate the dental care of each patient. Pearson χ, Fisher exact, and Mann-Whitney tests were used for data analysis, with a level of significance of 5%.

Results: Marked overjet (75%) and anterior open bite (70%) were the most frequent occlusal alterations, and 15% had Class III disorders. Radiography visualized the presence of impacted teeth (75%) and prolonged retention of deciduous teeth (65%). Patients with enzyme replacement therapy had a lower average maximum protrusion (P = .033). A total of 75% of mothers said they had not been advised to take their children to the dentist and 10% of children had never been to the dentist.

Conclusion: Patients with mucopolysaccharidoses exhibited notable occlusal alterations, especially marked overjet and anterior open bite. Enzyme replacement therapy seems to influence the maximum protrusion of patients.
