Comparison of surface disinfection method on frequently touched objects in dental clinic

Abstract

Objective To compare the bacteriostatic effect of two disinfections on the surface of frequently touched objects in dental clinic, so as to provide the reference for proper disinfection. Methods Specimens from the control panel and surface of examination table of comprehensive treatment chair were taken for bacterial culture, record the bac⁃ teria content on the objects surface. Then disinfect the objects surface by using 500 mg/L chlorine⁃containing disinfec⁃ tant (routing group) and Gamma disinfecting wet wipes (test group) respectively, compare the qualified rate of bacterio⁃ stasis on object surfaces between two group. Results After 10⁃minute disinfection on surfaces, bacteriostatic rate of routing group and test group was(91.66±7.52)% and (93.87±6.12)% respectively, there was no significant difference be⁃ tween two groups (P>0.05). Conclusion The quaternary ammonium disinfectant for the dental clinic objects can reach the same effect as chlorine⁃containing disinfectant.
