OBJECTIVE To prevent and control hospital cross-infection and hematogenous disease dissemination during oral cavity procedures.METHODS The problems that existed universally in instrument treating processes during oral cavity procedures were taken seriously.The perfect management rules and regulations were established.The instructions of technical operation were carried out strictly.We strengthened own-self occupation protection and implemented the standard prevention isolation principle.We guaranteed oral cavity synthesis method to implement,such as the instrument cleaning,disinfection,and antiseptic quality.RESULTS The hospital infection occurred in the oral cavity procedures could be reduced and avoided fundamentally through implementing infection control measure.The medical safety could be ensured.CONCLUSIONS The personnel standard diagnosing and treating operation of medical care should be established in hospital.The idea of disinfection and isolation asepsis should be enhanced.Own-self occupation protection must be required strictly.It is extremely important to control the infection during the oral cavity procedures.
