Abstract

BACKGROUND Periapical lesions are primarily caused by infections in the root canals. The objective of this study was to assess the antibacterial effectiveness of diode laser during root canal treatment in artificial models of infected periapical lesions. MATERIAL AND METHODS One hundred twenty-two extracted premolar single-rooted teeth were inserted into methyl methacrylate artificial models of periapical lesions, and bacterial solutions of Enterococcus faecalis (ATCC 29212) and Streptococcus mitis (ATCC 49456) were then applied to the models. The respective diameters of lesions in the artificial models represented 3 different subgroups based on lesion size. The laser protocol used for endodontic disinfection had a power output of 1.5 W and a wavelength of 810 nm. The impact on cell viability was evaluated by flow cytometry. RESULTS Disinfection with laser did not differ between microorganisms (P=0.137), and laser irradiation with a longer duration had better disinfecting action for both microorganisms (P.

二极管激光消毒人工牙根尖周感染的体外研究

背景:根尖周病变主要由根管感染引起。本研究的目的是评估二极管激光在感染根尖周病变人工模型根管治疗中的抗菌效果。材料与方法将拔除的122颗前磨牙单根牙置入甲基丙烯酸甲酯根尖周病变人工模型中，并应用粪肠球菌(ATCC 29212)和炎链球菌(ATCC 49456)细菌溶液对模型进行处理。人工模型的病变直径根据病变大小分为3个不同的亚组。用于牙髓消毒的激光方案功率输出为1.5 W，波长为810 nm。流式细胞术检测对细胞活力的影响。结果不同微生物间激光消毒效果无显著差异(P=0.137)，且激光照射时间越长对两种微生物的消毒效果越好(P=0.137)。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
