Effect of Nd:YAG Laser Irradiation to Mental Area on Human Dental Pulp Blood Flow Rate and Pulp Temperature Sensitivity Threshold Level

Abstract

College : We have reported pain relieving effects and blood flow changes in dental pulp by laser irradiation. The aim of this study was to investigate the threshold of thermal sensation and blood flow in dental pulp by low-power Nd:YAG laser irradiation to the mental foramen. Materials and Methods : Medical staff of Tsurumi University School of Dental Medicine with normal right lower canines received low-power Nd:YAG laser irradiation on the left mental foramen. Blood flow and the threshold of thermal sensation at
