Investigational Study of the Use of Er:YAG Laser Versus Dental Drill for Caries Removal and Cavity Preparation— Phase I

The FDA has recently cleared the Er:YAG to remove all classes of caries, form the cavity preparation, and modify the enamel and dentin prior to acid etching. In this Phase I study conducted as part of the clinical trials, there were no complications and no tooth was compromised. Patients were consistently treated without anesthesia with the same or better results than the drill as confirmed by scanning electron microscopy and histological studies.
