Il ruolo dell’igienista dentale nel trattamento laser dell’ipersensibilità dentinale

Objectives

The aim of the study is to assess and compare the desensitizing effects of Er:Yag laser and CO₂ laser with fluoride gel in the treatment of dentine hypersensitivity.

Materials and methods

The 15 patients selected are affected by hypersensitivity in the upper premolar; they have been treated randomly with Er:Yag laser, CO₂ laser, fluoride gel, and placebo. The pain was evaluated before the treatment by using the Visual Analogue Scale (VAS) and by air emission from a standard air-water syringe.

Results

There were statistically significant differences between the group treated with lasers and fluoride gel versus the group treated with placebo. There were no statistically significant differences between the groups treated with Er:Yag and CO₂ laser and the groups treated with fluoride gel and placebo.

Conclusions

Er:Yag and CO₂ lasers together with fluoride gel are useful in the treatment of dentine hypersensitivity.
