Clinical research in effect of chlorhexidine to reduce steam contamination in periodontal scaling / 中国实用护理杂志

ABSTRACT

Objective This research attempted at prevention of steam contamination and protection of medical staff in periodontal scaling. Methods Thirty sample patients without oral cavity or upper res-piratory tract infection, chronic disease, infectious disease or other contraindication were randomly classified into the experimental group and the control group.The former gargled with chlorhexidine in the process of periodontal scaling while the latter rinsing only. Oral cavity bacteria of both groups were sampled before and after operation;air samples were got at five periods of time(before operation, 10 minutes in operation, 20 minutes in operation, 30 minutes in operation, and end of operation) and germicnltured.The entire data were analyzed.Results Air samphng in periodental scaling and oral sample germiculture after the scaling in the experimental group were lower than those of the control group, P<0.01. Conclusions With effective disinfection and sta-ble characteristics, chlorbexidine can be popularly utilized in skin mucous membrane disinfection. Gargling with chlorhexidine in periodontal scaling eliminates bacteria and microorganism in oral cavity and resulting steam,thus reducing environmental pollution and protecting the health of medical staff.
