Treatment of hypersensitive teeth using neodymium:yttrium-aluminum-garnet lasers: a comparison of the use of various settings in an in vivo study.

The spectrum of the methods available to treat hypersensitive teeth is very great. The chances for success in the use of these different therapies are equally variable. Faced with the already successful effort of the Nd:YAG laser in the treatment of exposed tooth necks, the effectiveness of the use of different settings of the Nd:YAG laser on exposed dentine was examined in this clinical study. In the case of comparison of the therapy success of the laser settings amongst one another, no significant difference could be found. This leads us to a conclusion, that laser irradiation is therapeutically effective at very low settings.
