The Efficacy of Low-Level Laser Therapy Combined with Single Flap Periodontal Surgery in the Management of Intrabony Periodontal Defects: A Randomized Controlled Trial

Abstract

This study aimed at assessing the clinical outcomes of the Single Flap Approach (SFA) with the additional use of Low-level laser therapy (LLLT). The defects were treated as per the principles of SFA, whereby 20 defects received only SFA (control group) and 20 defects received additional LLLT for bio stimulation/bio modulation (test group). Stable primary closure of the flaps was obtained with vertical internal mattress sutures. Plaque indices (FMPS), clinical attachment levels (CAL), probing pocket depth (PPD), and gingival bleeding scores (FMBS) were calculated at baseline, and at the 3rd and 6th months in both groups. An EHI score of 1 was observed at all sites except for two, where a score of 2 in the control group at week 2 was observed. In the test group, the PPD reduction at 6 months was 3.60 ± 0.95 and in the control group it was 3.75 ± 0.91 mm. CAL gain at 6 months was 2.70 ± 1.36 mm and 3.45 ± 1.2 mm in the test group and showed no statistical significance. These data suggested the positive effect of LLLT over CAL gain; thus, LLLT may be combined with SFA to potentially enhance the early wound healing and higher clinical outcomes in terms of increase in CAL and decrease in PPD.

Clinical efficacy and pain control of diode laser-assisted flap surgery in the treatment of chronic periodontitis:A systematic review and meta-analysis

“…Wound healing is a complex process that involves the proliferation, differentiation, migration, and adhesion of various cell types. Different growth factors regulate the functions of these cells, which ultimately determine the rate and quality of healing [ 21 ]. Diode lasers exert additional effects on fibroblasts by promoting proliferation, increasing cell number, secreting growth factors, and differentiating fibroblasts into myofibroblasts.…”

Low-level laser therapy in dentistry

“…Periodontitis is an inflammatory disease of the gingiva and periradicular tissues initiated by pathogenic bacteria present in biofilms, releasing enzymes and triggering an immune mechanism, causing host-parasite interaction and subsequently, loss of attachment and bone loss [27] . It was found that if proper parameters are used when incorporating LLLT treatment such as photodynamic therapy they can be useful as an alternative therapy for periodontal disease [28] .…”

Remoção de tórus palatino associado a complicações pós-cirúrgicas: relato de caso

“…Além disso, inúmeros moduladores como a terapia a laser de baixa intensidade (LLLT) se tornaram ferramentas adjuvantes e bem aceitas na cicatrização das feridas, fazendo com que o comportamento das células seja alterado pela irradiação em um comprimento de onda específico (WALSH, 1997;ROCHA JÚNIOR et al, 2006;SILVIYA et al, 2022). Com isso, o metabolismo celular e a proliferação aumentam, otimizando assim o reparo tecidual.…”

“…Com isso, o metabolismo celular e a proliferação aumentam, otimizando assim o reparo tecidual. Deste modo, a LLLT se torna efetivo devido às suas propriedades físicas, bactericidas, anti-inflamatórias, analgésicas, de estimulação celular, de ablação e de proliferação (YAMADA, 1991;TADAKUMA, 1993;SILVA NETO et al, 2020;SILVIYA et al, 2022).…”
