Dentinal hypersensitivity (DH) is a painful condition that can affect a person's quality of life. Laser therapy is a valid treatment option for this problem, which leads to immediate and long-term pain relief. This study aims to comprehensively review the effects of different laser treatments on DH.
The search was performed in electronic databases, including PubMed, Web of Science, Embase, Google Scholar, and Scopus, published in English from January 2012 to October 2024. The following keywords were searched: Laser, Dentine hypersensitivity, Dental pain. Relevant laboratory and clinical studies were included.
Based on the electronic search, 988 articles were identified. Based on the search strategy and removal of duplicate articles, 47 articles remained. Finally, with the addition of 7 supplementary articles from a manual search, 16 in-vitro and 38 clinical studies were included. Application of high power diode laser at 980 nm and 2 W and Er;Cr:YSGG at a power of 0.5 W in a single session has been found to be a practical therapeutic approach in alleviating DH. The utilization of Nd:YAG was found to be inferior in high-power settings.
Both high/medium and low power lasers have the ability to relieve DH when used with appropriate output settings. These treatments demonstrate an instant pain-relieving effect upon application and also provide long-lasting advantages. Additionally, the simultaneous use of surface desensitizers, such as Gluma and substances that contain potassium nitrate with lasers, can be a practical approach for treating DH, especially when utilizing a low-power laser.
牙本质过敏症（DH）是一种会影响生活质量的疼痛性疾病。激光治疗是治疗该问题的有效选择，可立即和长期缓解疼痛。本研究旨在全面评估不同激光治疗方法对 DH 的效果。
在电子数据库中进行了检索，包括 PubMed、Web of Science、Embase、Google Scholar 和 Scopus，检索时间范围为 2012 年 1 月至 2024 年 10 月，使用的关键词为“Laser（激光）”“Dentine hypersensitivity（牙本质过敏）”“Dental pain（牙齿疼痛）”。纳入了相关的实验室和临床研究。
基于电子检索，共识别出 988 篇文章。基于检索策略和去除重复文章，保留了 47 篇文章。最后，通过手动搜索增加了 7 篇补充文章，共纳入 16 项体外研究和 38 项临床研究。发现 980nm 和 2W 的高功率二极管激光以及 0.5W 的 Er;Cr:YSGG 的单次应用是缓解 DH 的实用治疗方法。高功率设置下 Nd:YAG 的应用效果较差。
当使用适当的输出设置时，高/中功率和低功率激光都有缓解 DH 的能力。这些治疗方法在应用时即刻具有缓解疼痛的效果，并且还具有持久的优势。此外，同时使用表面脱敏剂，如 Gluma 和含有硝酸钾的物质与激光联合使用，可能是治疗 DH 的一种实用方法，特别是在使用低功率激光时。
