Effectiveness on oral pain of 808-nm diode laser used prior to composite restoration for symptomatic non-carious cervical lesions unresponsive to desensitizing agents

Abstract

This study compares sensitivity reduction after dental restoration with and without prior diode laser (DL) irradiation for cervical dentine hypersensitivity (CDH) from non-carious cervical lesions (NCCLs) unresponsive to desensitizing agents. Eighty-eight teeth of 28 subjects (21 females; age 23-64 years), with CDH from NCCL were included in this study. NCCLs of each oral quadrant were randomized in two groups (study group (SG)) to estimate the sensitivity reduction after dental restoration (SG-1) compared with the DL irradiation used prior to restoration placement (SG-2). The subjects were asked to rate the sensitivity experienced during air stimulation using a visual analog scale before (baseline), immediately after, and at 6 and 12 months from restoration. The outcomes showed a significant reduction of discomfort compared to baseline for NCCLs of SG-2 with the decrease of 78.5, 78.9, and 78.1 % immediately and at 6 and 12 months after restoration, respectively; in comparison with the decrease of 70.1, 67, and 65.3 % for NCCLs of SG-1 immediately and at 6 and 12 months after restoration, respectively; and compared to baseline. The DL irradiation prior to dental restoration can further improve the painful symptomatology of CDH from NCCL unresponsive to desensitizing agents.

Examination of the Effect of the Combined Use of Nd: YAG Laser Irradiation and Mechanical Force Loading on Bone Metabolism Using Cultured Human Osteoblasts

“…In recent years, laser therapy in the nearinfrared region (NIR) has attracted attention. These are used for periodontal therapy, 1,2 sensory hypersensitivity treatment, 3,4 and treatment of temporomandibular disorders. 5 On another study using a rat fracture model, there were reports that Nd: YAG laser and diode laser irradiation promoted bone healing 6,7 and that diode laser irradiation promoted bone grafting in rats and in vitro experiments.…”

Uso e eficácia clínica do laser no tratamento da hipersensibilidade dentinária: uma revisão de literatura

“…Femiano et al 25 realizaram um estudo para comparar a mudança da hipersensibilidade dentinária proveniente de lesões cervicais não cariosas (LCNCs) que não responderam ao tratamento com agentes dessensibilizantes e foram tratadas com restauração de resina composta associada ou não ao uso anterior do laser diodo de baixa potência. Foram incluídos neste estudo 88 dentes com hipersensibilidade proveniente de LCNCs.…”

A short term comparative evaluation of the efficacy of diode laser with desensitizing toothpastes and mouthwashes in the treatment of dentinal hypersensitivity

“…Although this short term study provided satisfactory results, the VAS scores post therapy could have been lower, especially with the DL group. However, the literature indicates that longer duration studies ( 34 , 35 ) have delivered such scores and one report ( 36 ) may not have reflected low VAS scores, but delivered clinically accepTable results.…”
