Opis:
Introduction and aim. The association between periodontitis (PD) and rheumatoid arthritis (RA) has been analyzed and described in literature. Periodontal pathogens, such as Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans are pointed as the common factors for both diseases. In this work we demonstrate that treatment of dental and oral diseases is an unconditional requirement for patients with RA. Material and methods. PubMed was searched with the keyword “rheumatoid arthritis” and “periodontitis” from May 1999 to January 2022, showed 181 articles. Ultimately 72 articles were included in the review. Analysis of the literature. The above mentioned pathogens exhibit multiple mechanisms that disturb immune and inflammatory responses of the human organism. Those mechanisms lead to the periodontal disease (PD) that may activate the systematic reactions which in turn lead to intensification of systematic diseases such as rheumatoid arthritis (RA). P. gingivalis has the ability to expresses PAD enzyme (peptidylarginine deiminase) and activates the citrullization process. Moreover, the bacterium produces gingipain cysteine proteinases, which degrade the mechanisms of immunological system. The latter pathogen, A. actinomycetemcomitans, expresses hypercitrullization in neutrophils. Conclusion. Both pathogens influence inflammatory response of the organism, through the common pro-inflammatory mediators for periodontitis and rheumatoid arthritis, intensify the clinical manifestations of both diseases.

Opis:
Background. Use of plant extracts and phytochemicals with known antimicrobial properties may have great significance in therapeutic treatments. Objective. To assess the in vitro antimicrobial potential and also determine the minimum inhibitory concentration (MIC) of Citrus sinensis peel extracts with a view of searching a novel extract as a remedy for periodontal pathogens. Materials and Methods. Aqueous and ethanol (cold and hot) extracts prepared from peel of Citrus sinensis were screened for in vitro antimicrobial activity against Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis and Prevotella intermedia, using agar well diffusion method. The lowest concentration of every extract considered as the minimal inhibitory concentration (MIC) values were determined for both test organisms. Confidence level and level of significance were set at 95% and 5% respectively. Results. Prevotella intermedia and Porphyromonas gingivalis were resistant to aqueous extracts while Aggregatibacter actinomycetemcomitans was inhibited at very high cncentrations. Hot ethanolic extracts showed significantly higher zone of inhibition than cold ethanolic extract. Minimum inhibitory concentration of hot and cold ethanolic extracts of Citrus sinensis peel ranged between 12-15 mg/ml against all three periodontal pathogens. Conclusions. Both extracts were found sensitive and contain compounds with therapeutic potential. Nevertheless, clinical trials on the effect of these plants are essential before advocating large-scale therapy.
