Paper Abstract

The purpose of this study was to evaluate the patient's response to cavity preparation using the Er:YAG laser in comparison to the mechanical drill. The study protocol contained the cavity depth and location, which had to be similar for both preparation methods. The patient's response was evaluated generally and according to the location and depth of the cavities. The study design was evaluated by statistical variance analysis and symmetrical tests. Within a time schedule of 9 months totally 103 patients with 206 cavities were treated conventionally and by laser. The drill was accepted as more inconvenient than the laser in 83 percent and 88 percent would prefer the laser for future cavity preparation. The local anesthesia needed for laser preparation could be reduced to nearly a half of the need for mechanical preparation. As a conclusion it can be stated that the Er:YAG laser partially can replace the drill for cavity preparation and contribute to a more comfortable caries therapy for the patient.
