Oral Manifestations in Patients with Glycogen Storage Disease: A Systematic Review of the Literature

Abstract

(1) Background: Glycogen storage disease (GSD) represents a group of twenty-three types of metabolic disorders which damage the capacity of body to store glucose classified basing on the enzyme deficiency involved. Affected patients could present some oro-facial alterations: the purpose of this review is to catalog and characterize oral manifestations in these patients. (2) Methods: a systematic review of the literature among different search engines using PICOS criteria has been performed. The studies were included with the following criteria: tissues and anatomical structures of the oral cavity in humans, published in English, and available full text. Review articles and paper published before 1990 were excluded. (3) Results: 757 articles were identified in the initial search. In the end, 45 articles that met the selection criteria has been analyzed. The information extracted from the articles was classified according to the type of GSD (Ia; Ib; II; III; V; XIV). Oral manifestations range from dental caries to severe periodontitis in paediatric patients, from diffuses and recurrent oral ulcers in the cleft lip and palate. (4) Conclusions: Although considered a rare disease, GSD can present a varied number of oral manifestations. Therefore, it is of great importance for the oral medicine specialist to know and classify them.
