Er:YAG激光对钛表面口腔致病菌的抗菌性能研究
廖娟, 郭骏, 林木
四川省医学科学院四川省人民医院口腔科
摘要:
通过贴膜法,研究Er:YAG激光对口腔常见致病菌的抗菌性能,以期为临床上激光的运用提供理论基础。以光滑纯钛片作为载体,选用5种口腔相关致病菌,Er:YAG激光对其进行照射,用贴膜法对其抗菌性进行检测,经过24 h的培养后,由菌落计数计算出该激光对各种细菌的抗菌率。Er:YAG激光对金黄色葡萄球菌、大肠杆菌、中间普氏菌、牙龈卟啉单胞菌及伴放线放线杆菌具有强烈的杀菌作用,抗菌率都达到了90%以上。Er:YAG激光对钛表面口腔致病菌具有良好的抗菌作用。

Antibacterial activity of Er:YAG laser against oral pathogens on titanium surface
Liao Juan, GuoJun, Ling Mu
Abstract:
To study the antimicrobial activity of Er: YAG laser against common oral pathogens by film applicator coating assay, so as to provide a theoretical basis for clinical application of laser Five kinds of oral pathogenic bacteria were irradiated by Er:YAG laser with smooth pure titanium sheet as a carrier The antimicrobial activity of Er:YAG laser was tested by film applicator coating assay After 24 hours of cultivation, the antimicrobial rate of the laser to various bacteria was calculated by colony counting Er: YAG laser had strong bactericidal effect on Staphylococcus aureus, Escherichia coli, Procteria intermedia, Porphyromonas gingivalis and Actinobacillus actinomycetes, and the bactericidal rates were all above 90% Er: YAG laser has good antimicrobial activity against oral pathogens on titanium surface
Key words:  Er: YAG laser  titanium surface  film applicator coating assay  oral pathogens
