Vital pulp therapy (VPT) is primarily intended to preserve the vitality of pulp tissues, which have been exposed for any reason. Various materials and techniques have been proposed to improve treatment outcomes, including the use of lasers. This study aimed to review the histological results of different dental lasers including low-level lasers, carbon dioxide (CO), erbium-doped yttrium aluminum garnet laser (Er:YAG), neodymium-doped yttrium aluminum garnet (Nd:YAG), erbium, chromium:yttrium-scandium-gallium-garnet (Er,Cr:YSGG) lasers, and diode lasers for VPT. This focused review included a comprehensive electronic search of Scopus, MEDLINE, Web of Science, and Google Scholar databases from 2000 to 2022 by two independent investigators. Different combinations of keywords were used, and reference mining of related papers was done. The review included studies related to histologic evaluation of laser-assisted vital pulp therapy that stated the laser parameters that were used. Articles with radiographic or clinical assessments or articles lacking necessary data were excluded. Non-English articles were excluded unless their abstract was in English and encompassed the necessary data. Most studies indicated the efficacy of lasers for reduction of inflammation, acceleration of healing, and increasing the thickness of dentinal bridge. According to the evidence, lasers used in combination with pulp capping agents are beneficial to enhance the success rate of VPT.
活髓治疗（VPT）主要旨在保留因任何原因而暴露的牙髓组织的活力。已经提出了各种材料和技术来改善治疗效果，包括使用激光。本研究旨在回顾包括低水平激光、二氧化碳（CO）、掺铒钇铝石榴石激光（Er:YAG）、掺钕钇铝石榴石（Nd:YAG）、掺铒、铬：钇-钪-镓-石榴石（Er,Cr:YSGG）激光和二极管激光在内的不同牙科激光用于 VPT 的组织学结果。这篇重点综述包括两名独立调查员在 2000 年至 2022 年期间对 Scopus、MEDLINE、Web of Science 和 Google Scholar 数据库进行的全面电子搜索。使用了不同的关键词组合，并对相关论文进行了参考文献挖掘。该综述包括与激光辅助活髓治疗的组织学评估相关的研究，这些研究都说明了所使用的激光参数。排除了仅进行放射学或临床评估或缺乏必要数据的文章。除非其摘要为英文且包含必要数据，否则排除非英文文章。大多数研究表明激光在减少炎症、加速愈合和增加牙本质桥厚度方面的功效。根据证据，将激光与牙髓盖髓剂联合使用有利于提高 VPT 的成功率。
