For this purpose, 3 types of lasers with different wavelengths, CO² laser, Nd: YAG laser, and Er: YAG laser, were used to determine the optimum conditions of radiation. The results were as follows. 1. CO² laser was found to be capable of sealing the dentinal tubules. It was observed that when a power output of 2W at pulse durations of 10ms and frequencies of 10-30pps was applied, the Super Pulse was able to seal the tubules allowing no excessive carbonization or cracking. 2. Nd: YAG laser was also found to have a sealing effect on the tubules but it was accompanied by various degrees of carbonization and cracking. 3. Er: YAG laser showed no sealing dentinal tubules effect., application/pdf}, pages = {115--123}, title = {象牙質に対するレーザー照射効果について : 第1報 各種レーザーのin vitroにおける形態学的研究}, volume = {24}, year = {1998} }
