【摘要】 根管治疗术是目前治疗牙髓病和根尖周病最有效和最常用的方法,其中根管冲洗是根管治疗的重要组成部分。目前,临床上常常应用注射器、声波、超声波等方法和联合各种冲洗液(生理盐水、NaClO、EDTA等)进行根管冲洗。然而,上述临床方法对根管不规则区域和根尖1/3的冲洗效果尚不能达到理想的临床预期效果。随着对激光研究的不断深入,发现水和羟磷灰石对波长为2940nm的掺铒钇铝石榴石(Er:YAG)激光有高度亲和力。因此,有学者提出利用铒激光活化根管冲洗是提高根管冲洗效果的一种有效手段。本文聚焦于铒激光活化根管冲洗技术的最新研究进展:光子诱导光声流(PIPS)技术和冲击波增强发射光声流(SWEEPS)技术。探讨铒激光活化根管冲洗技术在清除根管内玷污层、牙体硬组织碎屑、根管内细菌、防止冲洗液根尖挤出等方面的能力,并对铒激光活化根管冲洗技术的研究背景、技术原理以及相关临床研究进展进行简要的介绍,以期为临床选择相关根管清洁方式提供新思路。更多还原

【Abstract】 Root canal therapy is currently the most effective and commonly used method for the treatment of endodontic and periapical diseases,Root canal irrigation is an important part of root canal therapy.At present,in clinic,it is often used in combination with needle,sonic,ultrasonic and other methods and various irrigation fluid(physiological saline,NaCIO,EDTA,etc.) for root canal irrigation.However,the irrigation effect of the above-mentioned clinical method on the irregular area of the root canal and 1/3 of the root apex still cannot achieve the desired clinical effect.With the continuous deepening of laser research,it is found that water and hydroxyapatite have a high affinity for the erbium yttrium aluminum garnet(Er:YAG) laser with a wavelength of 2940 nm.Therefore,some scholars have proposed that the use of erbium laser to activate root canal irrigation is an effective means to improve the effect of root canal irrigation.This article focuses on the latest research progress of erbium laser activated root canal irrigation technology:Photon initiated Photoacoustic Streaming(PIPS)technology and Shock Wave Enhanced Emission Photoacoustic Streaming(SWEEPS) technology.Discuss the ability of erbium laser activated root canal irrigation technology to remove smear layer in the root canal,tooth hard tissue debris,bacteria in the root canal,and prevent the apex of the irrigation fluid from squeezing out,and briefly introduce the research background,technical principles and related clinical research progress of erbium laser activated root canal irrigation technology,in order to provide new ideas for clinical selection of related root canal cleaning methods.更多还原
