Oral hygiene and periodontal status in a group of patients with rheumatoid arthritis

Abstract

ABSTRACT Background Periodontitis (PD) and rheumatoid arthritis (RA) having similar clinico-pathological characteristics frequently affect the middle-aged population. Objectives To study the oral hygiene (OH) and periodontal disease (PD) status in patients with RA and without RA (control) and to investigate the association between PD and RA. Methods OH and PD were assessed in RA patients (n = 35) and controls (n = 35) using plaque index (PI), bleeding on probing (BOP), probing pocket depth (PPD) and connective tissue attachment loss (AL). RA severity was determined with a standardized disease activity score (DAS). Results Mean age of RAand control groups were 54.7 + 9.9 and 51.1 +7.1 years. Either group female participation was 91.4%. PI and AL in the RA group positively correlated with DAS (Spearman's rho 0.48, 0.67; P Conclusions RA is common in middle-aged females. RA patients' PI and DAS showed positive correlation which could be attributed to compromised OH practice resulted by increasing severity of RA. AL in RA group had positive correlation with DAS implying that severe PD leads to severe arthritis and vice versa. PI, BOP, PPD and AL are high in RA patients showing that they are prone to PD. RA patients may also lose teeth early.
