Abstract

Introduction: The aim of this study is to evaluate the efficiency of a 810 nm diode laser for the treatment of dentinal hypersensitivity.

Material and methods: twenty patients suffering of different degrees of this pathology were involved in this study. Our protocol consisted in cleaning and drying the surface of the concerned teeth. The evaluation of the pain was done by VAS method after using an air spray during 1 second at a distance of 1cm from the dental surface. We used a diode laser at 1 W ( in continuous and non-contact mode ) with a tangential direction of the beam to irradiate the concerned dental areas in scanning way (2 passages). The pain was re-evalua-ted as following : before irradiation, just at the end of the treatment, at one month and 6 months later.

Results: The irradiated teeth showed a significant reduction of pain after 6 months of post-op.

Conclusion: Based on our results and within the limits of our study, the use of diode laser (810 nm) can be advised for the treatment of dentinal hypersensitivity.
