This systematic review evaluated the role of Potassium-titanyl-phosphate (KTP) lasers in dental bleaching by comparing tooth color change and rise in intrapulpal temperature after bleaching with KTP, Neodymium-doped yttrium aluminum garnet (Nd:YAG), Er:YAG, and diode laser system. Following were the inclusion criteria: in vitro studies in English available in full text. Articles published between 2000 and 2021 were selected. The search for was conducted on PubMed, Cochrane library/CENTRAL, Wiley online library, ProQuest, Science Direct, and Hand searching/specialized registers. Keywords were used: "Lasers" [Mesh] and "Tooth bleaching" [Mesh] using Boolean operators. A total of four articles fulfilled the inclusion criteria. The quality assessment of studies included was undertaken independently as part of data extraction process. KTP lasers demonstrated more effectiveness in attaining color change in stained teeth and showed the lowest rise in intrapulpal temperature. Based on the data obtained in the present review, the choice of bleaching treatment is directly related to the type of discoloration, activation of the bleaching agent, and esthetic requirement. Although all bleaching procedures were effective in color change, the KTP laser showed better results when compared to other laser activation. The bleaching treatment protocol is directly related to the type of discoloration, activation of the bleaching agent, and esthetic requirement. It has been demonstrated that a faster change in color can be obtained when bleaching is performed in combination with a light source, i.e., power bleaching aiming for a more in-depth change of color.
本系统评价通过比较磷酸钛氧钾（KTP）激光、掺钕钇铝石榴石（Nd:YAG）激光、铒:钇铝石榴石（Er:YAG）激光和二极管激光系统漂白后牙齿颜色变化和牙髓腔内温度升高情况，评估了KTP激光在牙齿漂白中的作用。纳入标准如下：全文为英文的体外研究。选取2000年至2021年发表的文章。检索在PubMed、Cochrane图书馆/CENTRAL、Wiley在线图书馆、ProQuest、ScienceDirect以及手工检索/专业登记库中进行。使用布尔运算符，关键词为：“激光”[医学主题词]和“牙齿漂白”[医学主题词]。共有4篇文章符合纳入标准。作为数据提取过程一部分，对纳入研究进行了独立质量评估。KTP激光在使染色牙齿变色方面显示出更高的有效性，且牙髓腔内温度升高最低。基于本综述获得的数据，漂白治疗的选择直接与变色类型、漂白剂的激活以及美学要求相关。尽管所有漂白程序在颜色变化方面均有效，但与其他激光激活方式相比，KTP激光显示出更好的效果。漂白治疗方案直接与变色类型、漂白剂的激活以及美学要求相关。已证明，当与光源联合进行漂白时，即进行旨在实现更深入颜色变化的强力漂白时，可更快地获得颜色变化。
