Dentinal hypersensitivity

The 980 nm GaAlAs diode laser therapy induced a clinical reduction of the dentinal hypersensitivity after each laser application and a significant reduction from the statistic point of view of the values of the surface temperature of the teeth recorded at the end of the treatment compared to those at the initial visit.

The installation made for the standardization of the cold thermal stimulus permitted the production of such a stimulus and at the same time can be used for the standardization of other stimuli in liquid state (osmotic, pressure, pH).

In this preliminary study we demonstrated that the treatment was efficient, that is, worked in ideal conditions. However, a randomized study is necessary in order to prove the 980 nm GaAlAs laser therapy also works in real conditions.
