Brief summary

The aim of the present study was to compare the effectiveness of combined Er:YAG and Nd:YAG laser therapy to that of scaling and root planning with hand instruments in nonsurgical treatment of chronic periodontitis.

Detailed description

The aim of the present study was to compare the effectiveness of combined Er:YAG and Nd:YAG laser therapy to that of scaling and root planning with hand instruments in nonsurgical treatment of chronic periodontitis.Twenty-five systemically healthy patients with moderate-to-advanced periodontal destruction were selected for this study. The quadrants were randomly allocated in a split-mouth design to either combined Er:YAG (160 mj/pulse, and 10 Hz) and Nd:YAG laser (100 mJ/pulse, and 20 Hz) therapy (test group) or scaling root planning using hand instruments (control group). At baseline, 1 month, and 3 months after treatment, clinical measurements, including plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAL), and bleeding on probing (%) (BOP), were performed and gingival crevicular fluid and subgingival plaque samples were taken. The gingival crevicular fluid levels of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) were analyzed by enzyme-linked immunosorbent assay. Total antioxidant status (TAS)/total oxidant status (TOS) were analyzed by high-performance liquid chromatography and a novel automatic colorimetric method. Quantitative analysis of Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf), and Treponema denticola (Td) was performed using real-time polymerase chain reaction (PCR) procedures.
