Etching with the Er: YAG Laser

open access: yesJournal of Japanese Society for Laser Dentistry, 1994
レーザー照射によるエナメル質表面の性状については, 従来よりNd: YAGレーザーによるものやCO2レーザーによる報告は見られるが, その効果については明らかにされていない.私は, 保存学的立場より, Er: YAGレーザーをエナメル質面に照射し, エッチング効果が生じるかどうかについて検討を行った.歯科領域にレーザーを使用する場合, 使用するレーザー光の波長によって吸収係数が異なるため, また光の到達深度も異なってくる.この場合, あらかじめ正確に歯質の吸収係数を測定し, 到達深度を見積もっておくことが必要であり, 適切なレーザーを選ぶに当たって, 臨床応用には重要なことの一つである.熊崎 らは, 第1回レーザー歯学研究会において, 歯質の光吸収係数を詳しく検討した結果を報告し ...
