Endodontic management of taurodontism in a patient with Morquio syndrome: Case report of a 16‐year‐old girl

Abstract

AbstractBackground and aimMucopolysaccharidosis (MPS) type IV, referred to as Morquio A syndrome (MAS), is a rare genetic disorder characterized by an insufficient level in the storage of glycosaminoglycans within lysosomes. Diagnosis generally depends on clinical examination, skeletal radiographs, and histochemical tests. The condition is characterized by prominent skeletal deformities, limited joint mobility, significant growth impairment, abnormalities in tooth alignment, and defects in tooth enamel. The present clinical case report aims to provide details of a MAS case with peculiar dental findings, including multiple taurodonts where emergency dental treatment was rendered.Case representationA 16‐year‐old girl with short stature and prominent facial characteristics reported severe pain in the right maxillary back region. Clinical examination revealed multiple areas of alveolar bone loss, decayed #36, and temporary restoration on #16. Radiographic examination indicated multiple posterior teeth with taurodontism. Past medical history was confirmative of Morquio syndrome. Treating taurodonts endodontically is challenging due to the enlarged pulp chamber, shortened roots, and constricted root canal anatomy. Motorized canal preparation and the use of bioceramic sealer with single cone obturation were done to achieve the best results.ConclusionThe present case report encountered difficulty locating and negotiating the root canals and establishing the glide path. Using a dental operating microscope and stiff hand files for glide path and short‐length Niti rotary files helped achieve the desired results. Although MPS IV is not frequently seen in dental practice, persons with this syndrome can continue to have good oral and overall health if their dental and medical condition if appropriately managed.
