Protocolo de aplicação do laser de baixa intensidade em dentes com hipersensibilidade dentinária

Abstract

Several studies have demonstrated the success of laser therapy in the treatment of dentinal hypersensitivity, but failures may occur. Error in diagnosis, low or high doses, variations in application points, insufficient number of sessions can be factors responsible for the failure of the technique. The objective of this work is to conduct a bibliographic research on the use of low level laser in teeth with dentinal hypersensitivity. A literature review was conducted researching different experiments, studies and opinions on the treatment of dental hypersensitivity using low level laser. Creating a protocol of application for laser therapy in the treatment of dentinal hypersensitivity is a challenge, this occurs due to the great variation in times, sessions, points of application, dose in the studies in the literature, and most of them report the treatment success. Evaluating the studies cited in the literature review, we can conclude that: lower doses promote better results in the long term; Points of application in the cervical region and three sessions with a one-week interval between them promote positive effects.
