BackgroundThe aim of the present study was to evaluate whether different Nd:YAG laser applications as an adjunct to scaling and root planning (SRP) improve the healing response to periodontal therapy in smokers with periodontitis.MethodsThis clinical trial included eighty systemically healthy smokers with periodontitis. Patients were randomly allocated to a treatment group: SRP alone (group 1), SRP+low-level laser therapy (LLLT) with Nd:YAG laser (group 2), SRP+pocket debridement with ND:YAG laser (group 3), and SRP+combined pocket debridement and LLLT with Nd:YAG laser (group 4). Gingival index (GI), plaque index (PI), bleeding on probing (%), probing depth (PD), and clinical attachment level (CAL) were recorded, and gingival crevicular fluid (GCF) samples for metalloproteinase-8 (MMP-8) levels were collected at baseline, 1 month and 3 months after treatment.ResultsThere were no significant differences between the treatment groups for the GI, PI, and BOP (%) parameters and MMP-8 levels at any time points (p > 0.05). For moderately deep pockets, PD and CAL reductions were significantly greater in all test groups compared to group 1 (p ˂ 0.05). For deep pockets, these reductions were significantly greater in group 2 and group 4 compared to group 1 (p ˂ 0.05). PD and CAL reductions were generally similar between test groups (p > 0.05) except PD reduction between baseline and 3 months in deep pockets (p ˂ 0.05).ConclusionsThe findings of this clinical trial suggest that Nd:YAG laser applications may be beneficial on the healing response of smokers to non-surgical therapy compared to SRP alone.© 2022.
