ABSTRACT

BACKGROUND: History of rheumatoid arthritis (RA) increases risk of periodontal diseases. A pro-inflammatory condition noted in periodontitis is considered a trigger for RA. Thus, periodontal treatment aimed at attenuating the pro-inflammatory state could aid in potentially reducing the risk of RA. AIMS: The objective of this research was to assess the effect of periodontal therapy on rheumatoid factor, Disease Activity Score-28, anti-citrullinated protein antibody, and C-reactive protein levels in patients with chronic periodontitis (CP) and RA. MATERIALS AND METHODS: The sample consisted of 28 patients with CP and RA. The study was designed to be a double-blind, randomised controlled clinical study. The samples were randomly categorised to either the treatment group (n = 13) or the control group (n = 15). CP status (plaque index, bleeding on probing, probing pocket depth, clinical attachment loss), clinical rheumatologic status (Disease Activity Score), and biochemical status (C-reactive protein, anti-citrullinated protein antibody, and rheumatoid factor) were assessed at baseline and at follow-up at 8 to 12 weeks. RESULTS: The treatment group showed a highly statistically significant reduction in bleeding on probing (P < .005), probing pocket depth (P < .001), plaque index (P < .001), and C-reactive protein (P < .001); a gain in the clinical attachment loss (P < .001) and an improvement in Disease Activity Score-28 (P = .001) were observed at reassessment following nonsurgical periodontal treatment as compared to the control group. However, blood serum anti-citrullinated protein antibody (P = .002) and rheumatoid factor levels (P = .351) were found to increase from baseline to 8 to 12 weeks following subgingival scaling and root planing. CONCLUSIONS: Reduction of inflammation in the periodontium by nonsurgical periodontal therapy did not reduce anti-citrullinated protein antibody and rheumatoid factor levels. However, it has shown improvement in periodontal conditions, and remarkable changes were observed in the clinical Disease Activity Score and C-reactive protein levels of individuals with RA.

ABSTRACT

BACKGROUND: The hyperoxidative and a modified inflammatory state in obese individuals cause higher susceptibility to bacterial infection which influences the initiation and progression of periodontal disease. AIM: Our study was aimed to evaluate the role of nonsurgical periodontal therapy on the clinical parameters such as gingival index (GI), plaque index, pocket probing depth (PPD) and clinical attachment level (CAL), plasma-reactive oxygen metabolite (ROM) levels, and gingival crevicular fluid (GCF) resistin and serum resistin levels in obese or overweight and normal weight individuals with periodontitis. MATERIAL AND METHODS: Sixty individuals of age between 35 and 45 years of both the sexes were selected and categorized into two groups as thirty overweight or obese individuals with chronic periodontitis (Group I) and thirty normal weight individuals with chronic periodontitis (Group II). Clinical parameters, plasma ROM levels, and serum and GCF resistin levels were assessed at baseline and 2 months after periodontal therapy in both the groups and compared. RESULTS: Intergroup comparison of clinical parameters (GI, CAL, PPD) 2 months after therapy showed a significant difference with more reduction in Group II compared to Group I. On comparison, mean plasma ROM, GCF, and serum resistin levels at baseline was higher in Group I compared to Group II. When plasma ROM, GCF, and serum resistin levels were compared 2 months after therapy, the reduction was more in Group II compared to Group I. CONCLUSION: It is concluded that along with periodontal therapy, motivation of patients for weight reduction program is mandatory for obese or overweight individuals with periodontitis in order to improve periodontal health.

ABSTRACT

BACKGROUND: Tumor necrosis factor-alpha (TNF-α) is indicated to play a major function in chronic inflammatory disorders. OBJECTIVE: To assess and compare the cytokine level (TNF-α) in the serum of chronic periodontitis (CP), rheumatoid arthritis (RA), RA with CP, and healthy volunteers. MATERIALS AND METHODS: This original research was carried out on 80 participants, divided into Group-I 20 RA patients, Group-II 20 CP patients, Group III 20 RA with CP (RA + CP), and Group IV 20 healthy volunteers. Clinical periodontal and rheumatological parameters were assessed in all the four groups. Blood serum samples have been collected from all individuals and investigated for levels of TNF-α by mean of enzyme-linked immunosorbent assay. RESULTS: TNF-α level were remarkably elevated in the RA+CP group (30.5±2.2) followed by RA group (17.9 ± 3.6), and CP group (11.9 ± 0.96) when compared with the controls (5.5 ± 3.3). The results showed a statistical significance of P < 0.001. Correlation was not observed on comparision of clinical periodontal parameters and Rheumatological parameters with TNF-α levels. CONCLUSION: The outcome of this present research revealed the presence of higher levels of TNF-α in individuals with RA with CP in our samples.

ABSTRACT

BACKGROUND: Protease-activated receptors (PAR-1 and PAR-2) are found to be immensely exhibited in the periodontal tissues. These receptors are involved in the inflammatory and repair processes. Activation of PARs is mainly by the bacterial and endogenous enzymes. The aim of the study was to determine the role of PAR-1 and PAR-2 in initiating periodontal inflammation and to immunolocalize these receptors in the gingival tissues of healthy and chronic periodontitis individuals. MATERIALS AND METHODS: A total of 50 patients were selected for this study, of which 25 were healthy controls and 25 were chronic periodontitis patients. Gingival tissues were excised from the marginal gingiva and interdental papilla under local anesthesia (xylocaine with 2% adrenaline) during crown lengthening procedure or during periodontal therapy depending on the respective groups. Immunohistochemical analyses of PARs were done by staining the samples with hematoxylin and eosin and with primary and secondary antibody for PAR-1 and PAR-2. RESULTS: The Hematoxylin and Eosin staining showed more inflammatory changes in the periodontitis group compared to healthy gingiva. In chronic periodontitis, PAR-1-positive cells were seen in the basal layer with a weak expression and were showing negative expression in the superficial layer. In consideration of PAR-2, there was a very strong expression up to the superficial layer of the epithelium, compared to PAR-1. On comparing the intensity of staining in the connective tissue of chronic periodontitis sample, there was an increased expression of PAR-2 compared with PAR-1. A low positive expression of PAR-1 and PAR-2 was observed in the epithelium and connective tissue of the healthy tissues. CONCLUSION: The results clearly demonstrated the role of PAR-1 and 2 in periodontal inflammation.
