About this study
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:
- 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.
- To examine the contributions of laser therapy to tissue healing by analyzing biochemical markers in peri-implant sulcular fluid over time.
Read the 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:
- Evidence of visual inflammatory changes in the soft tissues around the implant, accompanied by bleeding and/or suppuration during probing
- Increased probing pocket depths compared to measurements obtained during the placement of the superstructure; and
- Progressive bone loss according to radiographic bone level assessment within 1 year after delivery of the implant-supported prosthetic reconstruction; and
- 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Low Level Laser TherapyDevice
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).
Non-surgical Periodontal TreatmentProcedure or surgery
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).
| Study group | Role | What they receive |
|---|---|---|
| Laser treatment | Experimental | Laser Group: Group with peri-implantitis to receive low-level laser therapy in addition to non-surgical treatment of peri-implantitis) Receives: Device: Low Level Laser Therapy; Procedure: Non-surgical Periodontal Treatment |
| Non-surgical treatment | Active comparator | Control group: Group with peri-implantitis who will undergo non-surgical treatment for peri-implantitis Receives: Procedure: Non-surgical Periodontal Treatment |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in clinical peri-implant index values from baseline to the third months after non-surgical treatment with or without adjunctive low-level laser therapy
In peri-implantitis sites, Plaque Index (Silness-Löe), Gingival Index (Löe-Silness), bleeding on probing, probing pocket depth, and clinical attachment level scores will be recorded before and after non-surgical treatment with or without adjunctive low-level laser therapy
Measured: 0-3 month
Secondary outcomes (1)
Change from baseline to the third months after non-surgical treatment with or without adjunctive low-level laser therapy in the regenerative biomarker levels in patients with peri-implantitis
Periostin and vascular endothelial growth factor levels in peri-implant crevicular fluid will be measured before and after non-surgical treatment with or without adjunctive low-level laser therapy in peri-implantitis sites, using the ELISA immunoassay technique.
Measured: 0-3 month

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Mehmet A Gunenc, DDs (+0905076310563, dtmehmetaligunenc@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in clinical peri-implant index values from baseline to the third months after non-surgical treatment with or without adjunctive low-level laser therapy (time frame: 0-3 month). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07128134, which also lists 15 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Aug 2025; AzTrials last refreshed its copy on 7 Nov 2026.
