【摘要】 激光因其高效、安全、便捷的优势可极大地提高牙齿漂白的临床疗效。目前应用于牙齿漂白的激光种类繁多，其中磷酸钛氧钾（KTP）激光可通过与光敏剂结合应用于牙齿漂白中，引发光动力效应，产生优异的漂白效果，且具有较高的安全性。KTP激光的波长特殊（532 nm），除了上述漂白作用外，可以对四环素着色牙起到直接的光化学氧化作用，有望应用于临床难治性着色牙齿的治疗，尤其是四环素着色牙的治疗。本文就KTP激光漂白的特点、机制、效率、安全性以及与其他激光漂白的比较等进行综述，为KTP激光应用于临床牙齿漂白治疗提供参考。更多还原

【Abstract】 Laser can greatly improve the curative effect of tooth bleaching because of its high efficiency,safety,and convenience.In recent years,many kinds of lasers have been used in tooth bleaching,among which KTiOPO₄ laser can be used in combination with a photosensitizer to exhibit a photodynamic effect,produce excellent bleaching effect,and confer higher safety.The special wavelength （532 nm） of this laser can also play a direct role in the photochemical oxidation of tetracycline-stained teeth.KTiOPO₄ laser is expected to be used in clinical treatment of refractory tooth coloring,especially in tetracycline-stained teeth.This paper reviews the characteristics,mechanism,efficiency,and safety of KTiOPO₄ laser and its comparison with other methods to provide reference for its application in clinical tooth bleaching.更多还原
