Clinical Study of Laser Analgesia in Cavity Preparations Using the Er,Cr:YSGG Laser

Completed · Not applicable

Conditions studied: Tooth Pain

In brief

Not much has been done in research to explain the clinical benefit of laser cavity preparation without the use of injection anesthetic. The Author of this study sought to show the science behind the "no shot, no pain" in restorative dentistry using an Er,Cr:YSGG laser Patients with two similar size lesions of class I or class V cavities selected as subjects. In the same appointment, both cavities are prepared by the Er,Cr:YSGG. One lesion was prepared with one high power laser setting to ablate the enamel, dentin, and caries. The other lesion was prepared with a low power setting to start and is aimed at applying low level laser therapy (LLLT) before using the high power setting to ablate enamel, dentin, and caries. A visual analog scale (VAS) was used for the patient to analyze how comfortable each laser technique was. An Analysis of Variance (ANOVA) was used.
