混合光源系统用于活髓牙漂白的临床研究进展

Hybrid light source in vital dental bleaching

自激光应用于活髓牙漂白,其显示出巨大的应用潜力,但同时也带来了髓腔升温、牙髓组织损伤、牙齿敏感等一系列的潜在风险。因此,大量的研究旨在寻求一种更加安全、可控的临床漂白方案,这些研究涉及了不同类型光源、不同光强度、不同浓度的漂白剂以及不同的漂白步骤。其中,应用发光二极管(LED)与低强度激光的混合光系统漂白方案因其较保守的漂白参数受到较大的关注。本文将对这一漂白系统的应用效果及安全性作一综述,以探讨其在活髓牙漂白中有效性及安全性的可能优势。

Laser shows great potential application in vital dental bleaching but includes many potential risks,such as temperature increase in pulp cavity,damage to pulp tissues,and tooth sensitivity.Therefore,many studies involving different light types,light powers,bleaching agent concentrations,and bleaching procedures have been conducted to develop a safe and predictable process for clinical bleaching.The application of light-emitting diode(LED)-low level laser hybrid light source has attracted attention due to its conservative bleaching parameters.In this paper,the efficacy and safety of this novel bleaching system are reviewed to explore its possible advantages in vital dental bleaching.
