Nonsurgical periodontal therapy with/without 980  nm diode laser in patients after myocardial infarction: a randomized clinical trial

AbstractThe purpose of this study was to evaluate the possible benefits (in terms of periodontal status improvement and periodontal bacteria count reduction) of using 980  nm diode laser in the treatment of periodontitis in patients after myocardial infarction. Thirty-six patients under 65 years of age (mean: 56.3 ± 7.9) with periodontitis, 6 weeks to 6 months after myocardial infarction, were recruited for the study. The control group (n = 18) received SRP (scaling, root planing and polishing) while the test group (n = 18) received SRP followed by laser therapy of the periodontal pockets with 980 nm diode laser, 1 W, continuous wave mode, 20 s per tooth side. Procedures were repeated twice at 5–7 day intervals. Microbiological and periodontal examination, including periodontal pocket depth (PPD), clin ical attachment loss (CAL), bleeding on probing (BOP) and plaque control record (PCR), were performed before treatment, 2 weeks and 3 months after treatment. The study was registered onClinicalTrials.gov with Identifier: NCT04145557, 29.10.2019 “retrospectively registered”. Additional use of laser resulted in a significant reduction in pockets with PPD ≥ 7 mm (p = 0.0151). The diode laser reduced total bacteria count (p = 0.0154) and delayed recolonisation during a 3-month observation period. A significant increase in the number ofCapnocytophaga gingivalis was observed in the control group (p = 0.048). Additional use of the diode la...
