Consumo de açaí e manifestações orais relacionadas a distúrbios gastrointestinais: revisão de literatura

Açaí (Euterpe oleracea Mart.) is part of the Amazonian diet and has considerable nutritional, economic, and sociocultural importance in Pará, Brazil. Investigating its potential relationships with gastrointestinal and oral health requires distinguishing dietary consumption from laboratory applications of its derivatives. This study aimed to discuss the scientific literature on açaí consumption, its potential relationships with gastrointestinal health, and oral manifestations associated with digestive disorders. A qualitative, descriptive narrative review was conducted using searches in PubMed/MEDLINE, the Virtual Health Library, and SciELO, supplemented by consultation of scientific journals and repositories through October 2026. Publications were selected according to thematic relevance, prioritizing human studies, in vitro dental research using human-derived materials, and reference documents. Studies involving animals or nonhuman animal-derived biological materials were not included in the synthesis. The analysis addressed the dietary context of açaí, reflux and oral manifestations, and dental applications of açaí derivatives. The sources discussed erosive tooth wear, oral symptoms, and self-reported halitosis, alongside experimental assessments of the dentin matrix and resistance to erosive challenges. Laboratory findings varied according to preparation and experimental protocol: some formulations showed favorable effects, whereas others did not demonstrate the same benefits. Evidence concerning reflux and oral changes does not, by itself, establish a role for açaí in these outcomes. The publications analyzed do not demonstrate a direct clinical relationship between habitual açaí consumption, gastrointestinal disorders, and oral manifestations. Interpretation should consider the nonexhaustive nature of the review and the limitations of extrapolating laboratory findings. Clinical investigations assessing dietary exposure, gastrointestinal diagnosis, and oral conditions together within the Amazonian context are needed.
