Evaluation of the Effects of Diode (980 Nm) Laser on Gingival Inflammation after
2016
Introduction: Periodontitis is an inflammatory disease, for which, scaling and root planning (SRP) is the common approach for non-surgical control of inflammation. Using lasers is another approach in the first phase of periodontal treatment for control of inflammation. Diode laser has some beneficial effects such as acceleration of wound healing, promotion of angiogenesis and augmentation of growth factor release. Thus the aim of this study is the evaluation of diode
Periodontal treatment with a low-level diode laser: clinical findings
General dentistry
This study assessed the effects of low-level laser treatment in combination with scaling and root planing (SRP) in patients with periodontitis. Sixty subjects with chronic advanced periodontitis were assigned randomly to three treatment groups (n = 20) after collecting gingival clinical parameters. Group A received SRP on a single quadrant per day for four consecutive days; on the fifth day, all quadrants were rescaled. Group B received the same treatment as Group A, followed by laser application for five days. Group C received the same treatment as Group B but the laser treatment was administered for a total of 10 days. For Groups B and C, a low-level diode laser (630 to 670 nm) was used. The plaque index, gingival index, and sulcular bleeding index were recorded for all groups. For all clinical parameters, all three groups reported statistically significant differences (p < 0.005) compared to baseline data. Compared to Group A, Groups B and C showed statistically significant im...

Aim: This split-mouth randomized trial (RCT) aimed to assess the effect of diode laser on the clinical parameters in patients with periodontitis, compare the results with scaling and root planing (SRP) alone, and assess the implications of diode laser (DL) on plaque bacteria. Materials and methods: Seventeen periodontitis patients were randomly assigned into two equal groups based on the therapy delivered. Group I (control site) received just SRP at baseline, while group II (test site) received both SRP and DL irradiation. For both groups, the clinical periodontal parameters probing pocket depth (PPD), and clinical attachment level (CAL) were measured at baseline, 30 days, and 90 days. Microbiological amount was also measured at baseline, 30, and 90 days after periodontal treatment. The amounts of Aggregatibacter actinomycetemcomitans (A.a), Prevotella intermedia (Pr. intermedia), and Porphyromonas gingivalis (P. gingivalis) were determined using real-time PCR probing with specific bacterial primers. Results: In both groups, PPD and CAL showed statistically significant reductions at different time intervals (p < 0.05). No significant difference were observed in CAL values after 1 and 3 months in both test and control groups (p > 0.05). The mean values of the concentration of A.a, Pr. intermedia and P. gingivalis were lower in the case group as compared to the control group and the difference was statistically significant after 1 month (*p = 0.001). Clinical significance: According to this study, non-invasive laser treatment has the potential to improve clinical outcomes by lowering the quantity of A.a, Pr. intermedia and P. gingivalis. Conclusion: In both groups, a considerable decrease in the periodontal pathogens A.a, Pr. intermedia and P. gingivalis were discovered; however, the intergroup comparison was insignificant in relation to PD and CAL. The adjunctive treatment with diode laser showed better efficacy in ensuring a better periodontal treatment than SRP alone.

The high intensity diode laser has been studied in periodontics for the reduction of subgingival bacteria in non-surgical treatment. Our study evaluated the bacterial effect as well as changes in periodontal clinical parameters promoted by root scaling and planing associated with this wavelength. Twenty-seven patients randomly assigned in two groups underwent root scaling and planing on the tested sites, and only the experimental group received the diode laser irradiation. Among the clinical parameters studied, the clinical probing depth (CPD) and the clinical attachment level (CAL) resulted in significant enhancement in the control group when compared with the experimental group (P = 0.014 and P = 0.039, respectively). The results were similar for both groups regarding the plaque index (PI) and bleeding on probing (BP). No significant difference in the microbiological parameters was observed between the control and experimental groups. It was possible to conclude that the high power diode laser adjunct to the non-surgical periodontal treatment did not promote additional effects to the conventional periodontal treatment.

Mechanical surface treatment and removal of the above and subgingival biofilm (Tartar ablation; SRP) are considered the most suitable tools for the treatment of periodontal inflammatory diseases, with the aim of destroying bacterial bioflim, reducing bacteria, and slowing down recolonization by pathogenic microorganisms. Often, however, the only S&RP are not enough, as there are patients who are experiencing relapses. Recently, laser therapy has been suggested as a potential tool to improve the outcome of periodontal non-surgical treatment. The objective of the following study was to evaluate the clinical healing of periodontal pockets treated with mechanical therapy, scaling and root planing, and diode laser application, compared to that obtained with non-surgical mechanical therapy alone. The study was designed as a randomized controlled clinical trial. Patients in the control group (13 patients) underwent conventional non-surgical therapy only, while patients in the test group (1...

The primary goal of periodontal therapy is the removal of supra and subgingival bacterial deposits by mechanical debridement consisting in scaling and root-planing (SRP) using manual or power-driven instruments. The complete removal of bacteria and their toxins from periodontal pockets is not always achieved with conventional mechanical treatment. The use of lasers as an adjunctive therapy for periodontal disease may improve tissue healing by bactericidal and detoxification effects. The aim of this study was to compare the effectiveness of Diode laser used as adjunctive therapy of SRP to that of SRP alone for non surgical periodontal treatment in patients with chronic periodontitis. Nineteen pairs of teeth with untreated chronic periodontitis were selected in 13 patients and randomly treated by SRP alone (control group) or by SRP + laser irradiation (test group). Clinical measurements (PPD, CAL, BOP, GI, PI) were performed before treatment at baseline (T0) and at T1 (after 4 weeks),...

Background: Periodontal therapy consists of eliminating the inflammation, treating periodontal pockets, motivating the patient for oral hygiene, and, if necessary, for surgical treatment. Recently, the application of a diode laser is widely being investigated for periodontal disease treatment. Objective: The analysis and evaluation of the clinical and biochemical impact of diode laser periodontal treatment, compared to either surgical or non-surgical, therapy, was the aim of this study. Methods: The study involved 80 patients older than 18 with at least 20 teeth. Evaluation of periodontal parameters was done conveniently on a single-rooted tooth (incisive, canine, premolar) on six surfaces, before the start of periodontal therapy, and after three, and six months. The laser used in the study was a diode laser with a wavelength of 980 nm. Digital X-rays were taken for bone level evaluation before and after the treatment. The presence of a bone destruction mediator (Matrix metalloprote...
EFFECT OF DIODE LASER TREATMENT ON THE LEVEL OF IL-6 IN THE GINGIVAL CREVICULAR FLUID IN PATIENTS WITH CHRONIC PERIODONTITIS, 2019
The aim of this trial was to determine the efficacy of Diode Laser Therapy (DLT) as an adjunct to scaling and root planing (SRP) in periodontal therapy on the basis of clinical measurements and level of IL-6 in gingival crevicular fluid (GCF). The study involved 40 patients with moderate chronic periodontitis, randomly assigned into two groups. The first group (test group) included 20 patients to whom the procedure SRP and additional application of DLT (808 nm) has been performed. The second group (control group) included 20 patients treated only by SRP procedure. In both groups the treatment has been applied in four visits twice a week. The clinical parameters of Hygiene index (HI), Bleeding on probing (BOP), Probing pocket depth (PPD), and Clinical attachment level (CAL) were measured at baseline and 1 month after treatment. Detection of IL-6 levels in GCF was conducted before treatment and four weeks after treatment completion. One month after treatment both groups showed significant improvements with regard to clinical parameters HI and BOP compared to baseline. The tendency of reduction in proinflammatory cytokine IL-6 level in GCF, recorded one month after treatment in the test group only, not in the control group showed the additional beneficial effects of DLT applied as an adjunct to SRP in the treatment of chronic periodontitis.

This study aimed to investigate the effects of diode laser (DL) in addition to non-surgical periodontal treatment on periodontal parameters, systemic inflammatory response, and serum hemoglobin A 1c (HbA 1c) level in patients with poor controlled type 2 diabetes mellitus (T2DM) and chronic periodontitis. Methods: 37 patients with poor controlled T2DM and chronic periodontitis completed this study. The patients were divided into two groups. The individuals in the control group received placebo laser treatment in addition to scaling and root planning (SRP). The individuals in the study group received DL (1 watt) in addition to SRP. Clinical index measurements were performed before treatment (T0), 3 months after treatment (T1), and 6 months after treatment (T2). Plaque index, gingival index, bleeding on probing, clinical attachment level, and probing depth were measured to determine periodontal status. HbA1 c and C-reactive protein (CRP) levels were also analyzed using blood samples. Results: In both groups, clinical and laboratory parameters were significantly improved at T1 and T2 compared to baseline (p<0.05). Gingival index, bleeding on probing, and probing depth were more significantly reduced after treatment in the SRP+DL group than in the SRP group (p<0.05). The serum CRP and HbA 1c levels were similar between the groups (p>0.05).

The aim of this study is to examine the clinical efficiency of diode laser periodontal pocket irradiation as an adjunct to conventional scaling and root planning (SRP) on periodontal parameters and halitosis. Material and Methods: In our randomized, controlled clinical trial, 40 patients with untreated chronic periodontitis were randomly separated into two group to receive SRP with laser (laser group n=20) or SRP solely (control group n=20). Plaque index (PI), gingival index (GI), probing pocket depth (PD), clinic attachment loss (CAL), bleeding on probing (BOP) and halitosis were recorded at baseline and 1st ,3rd and6th months after treatment by a periodontist. Results: Both treatment methods showed significant reductions in clinical parameters and halitosis levels compared to baseline. Conclusion: The present study indicates that compared to SRP solely, adjunctive applications of a 940-nm diode laser with SRP showed lower bleeding on probing and halitosis levels.
