No benefit of an adjunctive phototherapy protocol in treatment of periodontitis: A split‐mouth randomized controlled trial

Aim To assess the efficacy of a commercially available adjunctive phototherapy protocol (“Perio-1”) in treatment periodontitis. Materials and Methods In an examiner-blind, randomized, controlled, split-mouth, multicentre study, 60 periodontitis patients received root surface debridement (RSD) sextants either alone (control sextants) or with (test sextants). Re-evaluation was performed at 6, 12 24 weeks. Results No statistically significant differences mean (± standard deviation) clinical attachment level (CAL) change from baseline to week were observed between test (−1.00 ± 1.16 mm) control (−0.87 0.79 sites probing pocket depths (PPDs) ≥5 mm (“deep sites”) (p = .212). Comparisons for all other parameters (CAL sites, PPD deep sites/all bleeding on probing, plaque scores), intervals, failed identify any differences. Conclusions The did not provide additional benefits over those achieved by RSD alone. (German Clinical Trials Register DRKS00011229).
