We investigate a possible association of oral metal alloys with the presence of Prevotella intermedia in a group with rheumatoid arthritis (RA). Bacteriological tests in a case-control study were performed. Cases were 80 patients with RA (40 of them positive in Prevotella intermedia and 40 negatives in it). Controls were 81 subjects without RA (39 positive in Prevotella intermedia and 42 negatives in it). Univariate analysis identifies the presence of oral metal alloys (lingual fix retainers or metal/ceramic crown), male sex and the presence of gingival inflammation as predictors of the appearance of Prevotella Intermedia (P<.05). In multivariate analysis the presence of intraoral metal alloys was the strongest association with an OR=4.21 (P<.001). No difference in positivity of Prevotella intermedia is observed between groups. Then, intraoral metal alloys are related with the increase of Prevotella intermedia in subgingival pockets in adult population, independently of RA.
Keywords: Oral bacteria, prevotella intermedia, dysbiosis, oral metal alloys, rheumatoid arthritis.
