The study was designed as a randomized-controlled, single-blind and parallel design consisting of 80 patients with chronic periodontitis. Study consists of 4 groups, with 20 patients in each group. Group 1 received only NSPT, Group 2 received NSPT+LANAP, Group 3 received NSPT+LLLT, and Group 4 received NSPT+LANAP+LLLT. Clinical measurements of patients and gingival crevicular fluid (GCF) were taken before treatment and after 1 and 3 months. In GCF, interleukin-1beta, interleukin-10 and vascular endothelial growth factor were analyzed. Standard periapical radiographs were taken for radiographic measurements.~In moderate (4-6 mm) and deep pockets (7 mm and above), it was found that all groups treated with laser significantly decrease pocket depth (PD) and clinic attachment level (CAL) compared to Group 1. Group 3 caused significantly less gingival recession than all other groups. There was no statistical difference between the groups in biochemical markers. Radiographic analysis revealed that only Group 2 achieved significant bone filling compared to Group 1.~Bot LANAP and LLLT application in the deep pockets provide an additional contribution to NSPT. It has been found that LLLT administration leads to decrease in PD by creating a minimum recession.
In this study, it is evaluated the effects of laser assisted new attachment procedure (LANAP) and low level laser therapy (LLLT) and on clinical, biochemical and radiographic parameters in addition to non-surgical periodontal treatment (NSPT).
