Glossite migratória benigna em crianças com idade pré-escolar

Benign migratory glossitis (BMG), also known as geographic tongue (GT) or migratory erythema (ME), is a common benign oral condition of unknown etiology, but with psychosomatic, immunological, infectious and nutritional factors believed to be associated. It affects exclusively the tongue and it is marked by erosive migratory areas, isolated or multiple. This study aims to analyze the presence of this pathology in preschool age children, as well as to clarify its pathophysiological aspects. Scientific articles selected through the Google Scholar, Scientific Eletronic Library Online (SciELO) and Portal Regional da Biblioteca Virtual em Saude (BVS) platforms were analyzed. The search on the platforms happened through the MeSH descriptors: Benign migratory glossitis; Geographic Tongue; Preschoolers; Pediatric Dentistry.This condition has a multiform clinical aspect, highlighting the presence of erythematous erosive lesions with irregular withish/grayish edges, reminiscing the contours of a geographic map that, after regression, may return to the same place or to different areas, what gives the migratory aspect. Therefore, it is a benign anomaly that occurs mainly in early childhood, and its morphology is quite varied and without significant evidence that there is a predilection for sex. Treatment is nonspecific and appropriate to the symptoms.
