摘要: 激光辐射作用于生物组织发生的消融反应能够实现对生物硬组织如牙齿的磨削和切割, 相较于超声骨刀、高速涡轮机等传统手术器械具有独特的优势。本文综述了牙科激光消融特性研究进展, 重点介绍了激光波长、脉宽、能量等参数对消融效果的影响。当激光波长与水和生物组织基质的吸收波长相吻合时, 可提高消融率并减小对周围组织的热损伤, 因此选用牙组织主要成分水和羟基磷灰石吸收系数较高的相关波长的激光可以获得更好的消融效果; 在同样的能量、波长条件下, 为获得良好的消融效果, 激光的脉宽应小于牙组织的热弛豫时间, 而脉冲持续时间较长会产生热量积累引起周围组织热损伤, 纳秒激光消融后无玷污层, 同时牙小管呈开放状态, 具有较高的安全性; 单脉冲能量的增加在初期可能会引起消融率的进一步提高, 但在高能量水平下会表现出明显的饱和效应, 这与消融产物对消融的阻断效应有关。总之, 激光消融技术具有兼容性好、精确度高、可实现复杂形状切割等独特的优点, 可减少手术中的振动、骨屑和传统器械造成的磨损, 有效降低了病人的痛苦, 极大地提高了手术的快捷、安全和舒适性。本文对激光辐照参数(波长、脉宽、能量)与消融效果之间的潜在关系进行了探讨与总结, 为激光辐照参数的优化组合提供了参考。

Abstract: The ablation effect of laser radiation on biological tissue enables cutting and grinding of hard tissues likes teeth, which demonstrates unique advantages compared to traditional surgical instruments such as piezosurgery or high speed airturbine. This article provides an overview of the research progress on dental laser ablation characteristics, focusing on the relationship between ablation effect and laser parameters such as wavelength, pulse width and energy. It is shown that when the laser wavelength matches well with the absorption wavelength of tissue, the laser ablation rate can be improved and the thermal damage can be reduced. Therefore, selecting wavelength with high absorption coefficient of water and hydroxyapatite, the main components of dental tissue , will achieve better ablation results. Under the same energy and wavelength conditions, in order to achieve good ablation results, the pulse duration of the laser should roughly match the thermal relaxation time of dental tissue, and a longer pulse duration will cause heat accumulation, leading to thermal damage of surrounding tissues. It shows that when nanosecond lasers are used for ablation, there is no smear layer, and the dentinal tubules remain open, which has high surgical safety. As for pulse energy of lasers, it shows that increasing the single pulse energy may enhance the ablation rate in the initial stage, but at higher energy levels, a clear saturation effect occurs due to the obstructive effect of ablation products. In summary, laser ablation technology has unique advantages, such as good compatibility, high precision, ability to achieve complex cutting. It can reduce the vibration, bone debris and wear caused by traditional instruments during surgery, effectively alleviating the discomfortable of patient and greatly enhancing the speed, safety and comfort of surgery. This article comprehensively reviews and the potential relationship between laser parameters (wavelength, pulse width and energy) and ablation effects, providing a reference for the optimal combination of laser parameters.
