摘要

通过分析牙本质的形态变化和温度变化,评价不同波长高功率二极管激光治疗牙本质过敏的疗效和安全性。用五种不同的商用激光器照射人类第三磨牙,波长分别为808 nm、940 nm、976 nm和980 nm,有或没有使用光引发剂(活性炭)。使用热电偶监测温度变化,并通过扫描电子显微镜评估形态变化。在不使用光引发剂的情况下,波长为940 nm、976 nm和980 nm的激光可以促进牙本质小管的消除,而不会造成热损伤。波长为808 nm、940 nm、976 nm和980 nm的激光与光引发剂组合时,产生的温度变化比非光引发剂组更小,尽管没有观察到规则的熔融表面。除组1(808 nm无光引发剂)外,二极管激光参数对牙本质小管闭塞是潜在安全的。使用光引发剂仍然是一种有效的策略,以尽量减少辐照期间的温度变化。

In vitro study of the effects of diode laser on dentin hypersensitivity and evaluation of intra-pulpal temperature variation.

To evaluate the efficacy and safety of different wavelengths of high-power diode lasers for the treatment of dentin hypersensitivity by analyzing morphological changes and temperature variation. Human third molars were irradiated with five different commercially available lasers at wavelengths of 808 nm, 940 nm, 976 nm, and 980 nm, both with and without the use of a photoinitiator (activated charcoal). Temperature variations were monitored using thermocouples, and morphological changes were assessed through scanning electron microscopy. Lasers with wavelengths of 940 nm, 976 nm, and 980 nm, used without a photoinitiator, promoted dentinal tubule obliteration without causing thermal damage. Lasers with wavelengths of 808 nm, 940 nm, 976 nm, and 980 nm, when combined with a photoinitiator, resulted in even lower temperature variation compared to the non-photoinitiator groups, although no regular fused surface was observed. Diode laser parameters, except Group 1(808 nm without photoinitiator), are potentially safe for dentinal tubule obliteration. The use of a photoinitiator continues to be an effective strategy for minimizing temperature variations during irradiation.

期刊介绍: Lasers in Medical Science (LIMS) has established itself as the leading international journal in the rapidly expanding field of medical and dental applications of lasers and light. It provides a forum for the publication of papers on the technical, experimental, and clinical aspects of the use of medical lasers, including lasers in surgery, endoscopy, angioplasty, hyperthermia of tumors, and photodynamic therapy. In addition to medical laser applications, LIMS presents high-quality manuscripts on a wide range of dental topics, including aesthetic dentistry, endodontics, orthodontics, and prosthodontics. The journal publishes articles on the medical and dental applications of novel laser technologies, light delivery systems, sensors to monitor laser effects, basic laser-tissue interactions, and the modeling of laser-tissue interactions. Beyond laser applications, LIMS features articles relating to the use of non-laser light-tissue interactions.
