Consideraciones bucodentales en pacientes con síndrome de Morquio

Laburpena

Mucopolysaccharidosis type IV (MPS-IV) also known as Morquio’s disease in memory of the Uruguayan pediatrician Luis Morquio who described it for the first time, is a congenital disease caused by the deficiency of the enzyme N-acetylgalactosamine 6 sulfatase or enzyme B -Galactosidase. These enzymatic anomalies result in high amounts of mucopolysaccharides accumulating in different tissues of the organism. The enamel defects presented by patients diagnosed with Morquio syndrome are described in detail in the bibliography. These defects are an apparently constant feature in the disease and, therefore, make visits to the dentist necessary for their control, avoiding major problems. These defects consist of an abnormally thin enamel that is rough due to numerous tiny holes and an irregular surface. The thinness of the enamel results in an altered form and discoloration of the teeth, which added to the interdental diastemas, cause alterations in the occlusion. Apart from these defects, the enamel is histologically normal and has a normal hardness and radiodensity. Dental treatment of patients with MPS-IV requires multidisciplinary collaboration, because the oral manifestations of the disease can appear at any age, being sometimes tedious for the patient and complicated for the professional. Special mention should be made of the therapies used as a symptomatic treatment of the disease, as well as the management of the airway in the case of interventions under general anesthesia or sedation to treat certain pathologies of bucomaxillodental territory.
