dc.description.abstract | Objectives : The purpose of this study was to investigate the effect of non-thermal atmospheric pressure plasma jet(NTAPPJ) on surface properties and Streptococcus mutans disinfection of denture base resin. Methods : Self-cured denture base resin (Jet denture repair resin, Lang dental Mfg, co., USA) was used to make specimen(12 mm × 2 mm). To observe surface change before and after plasma process, surface roughness and contact angle were measured. For sterilization experiments, the surfaces of specimens were treated with nitrogen and air NTAPPJ for 1 minute after S. mutans was inoculated on the material surfaces. Results : Before plasma process, surface roughness of denture base resin was 0.21 §± 0.02 §. After air and nitrogen NTAPPJ process, surface roughness was 0.19 §± 0.03 §and 0.18 §± 0.01 §respectively. There was no significant difference(p>0.05). Contact angle of control group without plasma process was 83.81ß± 3.14ß, while after plasma treatment, contact angles of air NTAPPJ and nitrogen NTAPPJ groups were 63.29ß± 2.27ßand 46.68ß± 5.82ß respectively. The result showed a significant decrease in contact angle after plasma process(p<0.05). Compared to the control group 6020.33(CFU/mL) without plasma process, CFU decreased significantly after air NTAPPJ 90.75(CFU/mL) and nitrogen NTAPPJ 80.25(CFU/mL) treatment(p<0.05). Conclusions : It was considered that NTAPPJ can be used for denture disinfection without changing surface properties of materials. | - |
