| 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。 |

| 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 |
