Clinical evaluation of the immediate effectiveness of GaAIAs laser on the therapy of dentin hypersensitivity

Abstract: he aim of the present study was to determine the effectiveness of GaAlAs laser therapy with λ670nm laser on the treatment of dentin hypersensitivity. Thirty-two intact human teeth were evaluated, the sensitivity of which to thermal (cold water), mechanical (probe) and evaporative (air) stimuli was recorded before and immediately after irradiation. Whenever desensitization was not observed after the first application, the patient was scheduled for a maximum of three further applications at 4-day intervals. The … Show more

“…46 In the literature, there are many contradictory studies for the treatment of DH using low-level lasers. 19,22,[47][48][49][50] These differences are caused by the fact that there are various types of lasers and variety in laser parameters. Several other factors could have influenced results, such as surgical extension (number of teeth involved), time required to perform the surgical procedure, gingival inflammation grade, and number and severity of periodontal pockets.…”

“…However, there are many contradictory studies regarding the efficacy of lasers in the treatment of root sensitivity this is because of no general consensus regarding the use of laser parameters and their frequency of application. [ 32 33 34 ] Thus, to strengthen the evidence regarding the efficacy of lasers and to draw the attention of researchers toward the most neglected aspect, that is, root sensitivity which might negatively influence the patients' compliance and hamper the postsurgical results, this study was conducted.…”

“…A redução na primeira sessão permite que o paciente melhore sua qualidade de higiene oral (NOYA, 2004). A dessensibilização por estimulação térmica deve ser considerada primeiramente pelo profissional, já que representa uma das principais queixas dos pacientes e com a melhora estabelecesse uma relação de confiança entre o profissional e o paciente desde a primeira sessão (NOYA, 2004). Comparando resultados com os grupos placebo, tanto no teste táctil quanto no térmico evaporativo, o grupo laser obteve diminuição significativa na sensação dolorosa (SARTORI,…”
