(a) all contact with the patient's wounds and blood instruments (handpieces, needles, expanding needles, extracting forceps, tappet, chisel, scalpel, periodontal scaling device, teeth cleaner, etc.) each person must be strictly sterilized after use. Commonly used dental examiners, fillers, trays, etc. are required to be sterilized after each person's use as required.
(b) the instruments as far as possible using physical sterilization method sterilization, hospitals with conditions can be equipped with rapid pressure steam sterilizer, such as the use of chemical sterilizing agents, must be carried out on a daily basis for the determination of the effective concentration of the...?
(3) The impression, wax block, plaster model and various restorations in the restorative technician's room should be sterilized using a medium-effective or higher sterilization method.
The dental special radiography room should strictly control cross infection in filming.
Ultraviolet light should be used for indoor air disinfection. For each case of patients each visit to ask for a detailed medical history, as far as possible to understand the clinical operation of the oral cavity related to cross-infection of important diseases, if necessary to do the appropriate laboratory tests, each patient with chlorhexidine solution rinse before treatment to reduce the oral colonies.
Medical personnel must establish a sense of protection and the implementation of operating procedures universal precautions because from the patient's medical history and examination can not reliably determine whether the infection of AIDS (or other blood-borne infectious diseases, the same should be consistent with the treatment of any patient to take preventive measures to isolate.
The dentist's hand is an important medium of cross-infection should develop the habit of wearing gloves and washing hands, in the process of oral treatment, wearing uniforms, masks, hats, disposable gloves and protective goggles, and wash hands after each case of patient treatment. The principle of aseptic operation, avoid wearing contaminated gloves to take the sterile items during treatment, try to use the foot-controlled switch to adjust the treatment chair, use disposable cover for the lighting switch; in addition, be careful in the process of treatment to prevent accidental injury to themselves or patients.
Disinfection and sterilization of oral medical equipment
General oral equipment disinfection and sterilization of used non-disposable oral equipment should be disinfected, cleaned and sterilized according to the procedures. Various types of needles, expanding needles, pulpotomizing needles, periodontal scaling devices, scalers and other small instruments after use, first soaked in glutaraldehyde, and then rinsed and dried with water. Sorting and packing are sterilized by small autoclave. Extraction forceps, dental tines, non-disposable trays, probes, forceps, gingival separators, dental chisels, bone chisels, needle holders, scissors, glass plates, picking digger, mold tray, silver mercury filler, metal carving knives, triple guns, etc., after the use of chlorine-containing, soaking, rinsing and wiping the classified package using high-temperature steam sterilization. Oral examination equipment are used disposable items, such as disposable oral instruments box, saliva inhaler, mouthwash cups, syringes, gloves, etc., soaked in chlorine-containing disinfectant after use, soaked containers to be covered, after the initial elimination of the supply room recovery and centralized disfigurement of classified yellow plastic bags and then loaded into the special sealed barrels locked in a fixed location placed, the daily by the local environmental protection department designated by the special medical waste recycling company door-to-door recycling for harmless disposal, and to do a good job. Harmless treatment, and do a good job of handover registration, prohibited back to the market.
Cleaning handle, high-speed turbine handpiece disinfection and sterilization of high-speed turbine handpiece, is the most used in the dental clinic, the most serious contamination of medical equipment, its internal more difficult to disinfect. Treatment will be completed steam switch on, rinse the water vapor system, with glutaraldehyde cotton ball will be around the drilling needle to wipe off the residual dirt, the drilling needle is removed, and then the handpiece is removed, and then wipe the handpiece with glutaraldehyde cotton ball external, rinse with water and wipe it dry, from the mouth of the tube
Sprayed into the dental handpiece cleaning lubricant, bag sealing indicate the date of sterilization, and then put into the small pre-vacuum high temperature steam sterilizer, turn on the power to start! Sterilizer, select the program and sterilization temperature and time.
Management of hospital-acquired infections in outpatient dental clinics
Departments should be established in the hospital infection management team by the department head, head nurse and part-time monitoring of the room doctors, nurses. Under the leadership of the director of the department to carry out work, responsible for the management of hospital infections in the department, according to the characteristics of hospital infections in the department, the development of management systems, and organization and implementation. Organize training for the prevention and control of hospital infection in the department.

Sterilization effect monitoring Sterilization effect monitoring is necessary to determine whether the sterilized items are qualified or not. In accordance with the People's Republic of China *** and the Ministry of Health, "disinfection technology specification", "hospital infection management standards" requirements for regular monitoring. The use of disinfectants, disinfectants monitoring biological monitoring disinfectants several times a month, the bacterial content must be controlled within the specified range; disinfectants monitored several times a month, shall not detect any microorganisms; chemical monitoring should be based on the disinfection, disinfectant performance regular monitoring, such as chlorine-containing disinfectants should be monitored on a daily basis, glutaraldehyde should be monitored on a weekly basis. Disinfection of goods, sterilization effect monitoring monthly disinfection, sterilization of goods for disinfection, sterilization effect monitoring, disinfection of goods shall not detect pathogenic microorganisms, sterilization of goods shall not detect any microorganisms. Ultraviolet disinfection should be carried out daily monitoring and ultraviolet lamp irradiation intensity monitoring. Daily monitoring includes lamp application time, cumulative exposure time and user's signature. New and in-use ultraviolet lamps to monitor the intensity of exposure, the intensity of exposure to new lamps should be used in the lamp.
