Summary

The main objective of this study is to evaluate the clinical efficacy of low-level laser therapy (LLLT) in addition to non-surgical periodontal treatment in patients with peri-implantitis. The study aims to investigate the anti-inflammatory and regenerative effects of low-level laser therapy on peri-implant soft and hard tissues and to reveal its contribution to treatment success. In this context, the specific objectives of the study are as follows: 1. To evaluate the effects of LLLT added to non-surgical mechanical treatment on clinical parameters such as plaque index, probing depth, bleeding index, and clinical attachment level. 2. To examine the contributions of laser therapy to tissue healing by analyzing biochemical markers in peri-implant sulcular fluid over time.

Detailed description

This study will include volunteers who were diagnosed with peri-implantitis based on clinical and radiological examinations at the Department of Periodontology, Faculty of Dentistry, Hatay Mustafa Kemal University. Seventy-two patients will be included in the study. In our study, patients will be divided into two groups. Thirty-six patients in the test group will receive low-level laser therapy in addition to non-surgical periodontal treatment. Thirty-six patients in the control group will receive only non-surgical periodontal treatment. Periodontal indexes including plaque index, gingival index, bleeding on probing, probing pocket depth, and clinical attachment level will be recorded and peri-implant sulcus fluid will be collected from patients for routine diagnostic procedures. These measurements will be performed at baseline and at 1.5th and 3rd months by same researcher. The following are required for a diagnosis of peri-implantitis: 1. Evidence of visual inflammatory changes in the soft tissues around the implant, accompanied by bleeding and/or suppuration during probing 2. Increased probing pocket depths compared to measurements obtained during the placement of the superstructure; and 3. Progressive bone loss according to radiographic bone level assessment within 1 year after delivery of the implant-supported prosthetic reconstruction; and 4. In cases where initial radiographs and probing depths are not available, a radiographic bone level of ≥3 mm and/or probing depths of ≥6 mm, along with the presence of bleeding, indicates peri-implantitis. Study Treatment Protocol: In the test group diagnosed with peri-implantitis, low-level laser therapy (LLLT) will be administered three times (on the same day as the initial treatment, on the 3rd day, and on the 7th day) in addition to non-surgical periodontal treatment by using A 940 nm indium gallium arsenide phosphor diode laser (Epic Biolase, Irvine, CA, USA). PIOS regenerative (periostin) and inflammatory (vascular endothelial growth factor (VEGF), and interleukin-1 beta (IL-1ß)) biomarkers will be analyzed biochemically using the ELISA method (Enzyme-Linked Immunosorbent Assay) at the Department of Biochemistry, Faculty of Medicine, Hatay Mustafa Kemal University.

Interventions

Type	Name	Description
DEVICE	Low Level Laser Therapy	Although low-level laser therapy has been applied in cases of periodontitis, there are only a limited number of studies investigating its additional benefits in implants with peri-implantitis. This study aims to contribute to the literature on this subject. In addition to surgical periodontal treatment, low-level laser therapy (LLLT) was applied three times (on the same day as the initial treatment, on the third day, and on the seventh day) to the implants in the test group diagnosed with peri-implantitis. The 940 nm indium gallium arsenide phosphor diode laser (Epic Biolase, Irvine, CA, USA) will be applied perpendicular to the periodontal pocket for 20 seconds at a fixed distance of 15 mm and a continuous wavelength (3.41 J/cm2 application with a 1.76 cm2 spot and 0.3 W average output).
PROCEDURE	Non-surgical Periodontal Treatment	Peri-implantitis diagnosis will be made in the control group, and non-surgical periodontal treatment of implants will be performed using titanium curettes (Hu-Friedy, Chicago, IL, USA).
