The authors analyse the use of laser CO2 in endodontic surgery. They describe the laser biological effects on teeth, comprehending immediate structural changes (coagulation, carbonization, volatilization, fusion of dental tissue), and side effects (sterilization, modification of biomechanical properties and biostimulation). A surgical technique joining traditional aspects and laser radiation, restoring the apical shape to the anatomical origin is described. The employment of the laser in a defocalized way allows the sterilization of the apical region even in zones normally not reachable by the usual instruments. These devices are connected with laser irradiation and could improve the clinical results either improving bone restoration on raising dental tissue resistance to acidity. The authors emphasize that, whereas the clinical follow-up is in fact similar to the results obtained in a previous traditionally treated control group an accurate surgical technique will be the real important aspect to reach the recovery and the laser irradiation can help in it.
作者分析了激光二氧化碳在牙髓手术中的应用。他们描述了激光对牙齿的生物学效应，包括即时结构变化（凝固、碳化、挥发、牙组织融合）以及副作用（杀菌、生物力学性能改变和生物刺激）。文中描述了一种结合传统方法与激光辐射的手术技术，可将根尖形态恢复至解剖学原状。以散焦方式使用激光能够对根尖区域进行杀菌，即使在常规器械通常无法到达的区域也能如此。这些设备与激光照射相关联，通过改善骨修复或提高牙组织耐酸性，可提升临床效果。作者强调，尽管临床随访结果实际上与先前传统治疗对照组所获结果相似，但精确的手术技术才是实现恢复的真正关键因素，而激光照射对此有辅助作用。
