Periodontitis often persists despite scaling and root planing (SRP), particularly in deep periodontal pockets where complete elimination of subgingival biofilm remains challenging. Adjunctive diode laser therapy has been proposed to enhance periodontal healing through its antimicrobial and anti-inflammatory effects. To explore this potential, a study evaluated the clinical efficacy of high- and low-intensity diode laser therapy as adjuncts to SRP among 27 patients with periodontitis.
The study found that all three treatment approaches significantly improved plaque index, gingival index, probing pocket depth, and clinical attachment level over time. High-intensity diode laser therapy showed significantly greater clinical attachment level gains at T1 compared with SRP alone and low-intensity diode laser therapy, with these benefits remaining significant at T2 versus SRP and low-intensity…
