Oral manifestations during dengue infection: a systematic review

Dengue is a global public health problem, especially in countries with tropical and subtropical climates. Aim: To describe the oral manifestations, present during dengue infection. Materials and method: A qualitative systematic review was conducted in OSF Registries. The search was conducted in PubMed, Scielo and Scopus, from June 15 to July 18, 2023, using MeSH term equations with Boolean operators. A total 299 articles were analyzed in three stages, leaving 8 studies for review. RAYYAN was used for selection and tables for study analysis. Studies were assessed under two criteria: metadata, and intraoral and extraoral manifestations of dengue. Results: The review included 8 studies, published in 2012, 2013, 2014, 2019, 2020 and 2021. The studies reported hemorrhagic dengue and type 1 dengue as diagnoses. They recorded presence of hemorrhagic and edematous gums, maculopapular lesions in the mucosa of the lower lip with pain and dysphagia, Pseudomembranous candidiasis, and edematous and erythematous taste buds. Conclusions: Reports of oral manifestations of dengue are deficient, and further research is required to enable correct diagnosis and differentiation from other pathologies.
