Effect of the clinical application of the diode laser (810 nm) in the treatment of dentine hypersensitivity

BMC Res Notes. 2014 Jan 13:7:31. doi: 10.1186/1756-0500-7-31.


Background: Dentine hypersensitivity is a common clinical finding with a wide variation in prevalence values. The aim of this study was to evaluate the use of diode laser (810 nm) in the treatment of cervical dentine hypersensitivity.

Methods: Five patients, with at least two sensitive teeth were selected. A total of 14 teeth were included in this trial. By using Visual Analogous Scale the pain of dentine hyper sensitivity was detected and the pre- treatment readings were recorded.The Diode laser (810 nm), was irradiated on (non contact) mode at the cervical region.The samples were divided into two groups according to exposure duration: For Group 1 exposure duration was 30 seconds and for group 2 exposure duration was one minute.The efficiency of the treatment was assessed at two examination period :15 minutes after first application and 7 days after first application, the degree of sensitivity was determined by using Visual Analogous Scale.

Results: The results show significant reduction of pain after 15 minutes of laser application in the group with 30 seconds exposure duration (P = .001), and the pain completely fade away after one week in the same group, while in the group with 1 minute exposure duration the pain completely disappeared (visual analogous scale = (0)) after 15 minutes and one week of laser application (P = 0.001).

Conclusion: The study concluded that application of diode laser (810 nm) was effective for the reduction of dentine hypersensitivity.
