Periodontal Treatment in Rheumatoid Arthritis Patients
Effects of Non-surgical Periodontal Therapy (NSPT) in Patients With and Without Rheumatoid Arthritis (RA)
Periodontitis is a chronic disease that leads to the loss of teeth. It has been associated to rheumatoid arthritis (RA). Periodontal therapy (NSPT) has been shown to have systemic effects. The objective of this study was to compare the effects of non-surgical periodontal therapy on biochemical parameters of rheumatoid arthritis (RA), periodontal parameters and quality of life in patients with and without RA.
Adult patients with and RA and periodontitis can participate in the study. Participants benefit from the effects of conventional tooth cleaning (periodontal therapy) and oral hygiene instructions. There are no significant risk associated with periodontal therapy.
The study is conducted at the Universidad de Antioquia in Medellin, Colombia. The study is set to start 2019 and end mid 2021. The study is funded by a grant from the Universidad de Antioquia. Contact person: Javier Enrique Botero (javier.botero@udea.edu.co)

After participants are screened for inclusion, serum samples will be collected for the analysis of C-reactive protein (CRP; mg/L), rheumatoid factor (RF; UI/mL) and anti-citrullinated protein antibodies (ACPAs; UI/mL) in a reference laboratory. A complete periodontal chart will be carried out at six sites per tooth excluding third molars by a single experienced clinician using a calibrated probe (Hu-Friedy Mfg. Co.). Subgingival plaque samples will be collected by means of paper points inserted to the bottom of the pocket and processed immediately for culture analysis and detection of Porphyromonas gingivalis. RA patients will be examined by an experienced rheumatologist to determine their Disease Activity Score (DAS-28). All examinations will be taken at baseline and repeated 3 months after intervention.
Non-surgical periodontal therapy (NSPT) will be administered on the following 5 days of inclusion. A single 1-hour session of full-mouth debridement with an ultrasonic device will be carried out in each participant under local anesthesia by an experienced clinician. After NSPT is completed, each patient will receive oral hygiene instructions and oral care pack including toothbrush and toothpaste (toothbrush Vitis Encias Medium; Toothpaste Vitis Encias; Dentaid, Colombia).
Demographic ,clinical history as well as medication data for all participants will be collected. Periodontal parameters of PD (mm), PAL (mm) and BOP (%) will be recorded at each visit. The stage and grade of periodontitis will be established according to the new classification of periodontal diseases (Papapanou et al. 2018). The clinician who records data will not be blinded to the condition of the patients.
Sample size was calculated to detect a 50 % change in CRP with a power of >80% (alpha 0,05) which resulted in 15 per group (Cosgarea et al. 2018). Considering possible dropouts, 20 participants will be included per group. Randomization will not be performed since the purpose was to compare the effects of NSPT in patients with and without RA. The clinical investigator who records periodontal parameters will be calibrated for repeated measurements before patient inclusion (Kappa value was ≥0.80 for PAL and PD). Continuous variables will be presented as the mean and 95% confidence interval (CI) or median [interquartile range] when appropriate. Change in biochemical markers (CRP, RF, ACPAs) and periodontal parameters (PAL, PD, BOP, microbial counts) will be expressed as the delta (∆) from baseline to 3 months after intervention. Differences in means will be determined by the student t test for paired and unpaired samples or non-parametric tests when appropriate. Categorical variables will be presented as frequencies (%) and analyzed in contingency tables and X2. Logistic regression analysis for categorical variables and linear models will be used to test for associations and the odds ratio with 95%CI will be calculated. The primary analysis will be performed as intention to treat and then compared to per-protocol analysis results. The level of statistical significance will be set at 5% (P≤0,05).
