2, all the instruments that come into contact with the patient's blood in the wound, such as silver mercury filling instruments, pulpotomizing needles, expanding needles, extracting forceps, dental extractors, bone chisels, scalpels, periodontal curettes, etc., are sterilized with high temperature and pressure after each person's use.
3, where the patient's oral cavity into the water and air gun head are taken one person, one with a replacement. Technician materials, dental molds and other materials need to be sterilized in chlorine-containing disinfectant after use, occlusal devices, fixed or movable restorations, orthodontic appliances and other instruments need to be cleaned and disinfected before placing them in the patient's mouth.
4, the use of dental handpieces for one person, mouth mirrors, forceps, probes, etc. are all encapsulated and sterilized for one person in one set. Needles, fillers, trays, etc. are sterilized for one person for one use, and chemical sterilizers are used to sterilize instruments that are not resistant to high temperatures.
5, strictly require doctors to wash their hands and wear gloves before treatment, and change gloves when treating each patient. In the process of treatment can not wear gloves to answer the phone, write cases, contact with objects.
6, the treatment chair on the headgear, lamp handle, treatment table using the isolation film, one person, one use, one replacement. Increase the use of disposable oral instrument boxes, mouthwash cups, syringes, mouth mirrors, forceps, probes, small brushes, strong suction, saliva suction and other instruments.
7, strict implementation of disinfection and isolation system, mastery of aseptic operation techniques, the use of controllable air sterilizer every day after work timed to open the clinic environment for strict disinfection; strict compliance with aseptic operation procedures, strengthen the personal protection of medical personnel, dental clinic room to keep clean, with ultraviolet radiation at the end of each working day, and keep well ventilated. The treatment table is wiped and disinfected with chlorine-containing disinfectant after treating each patient, and the surface of the comprehensive treatment chair and the work table contaminated by patient's blood, saliva or other secretions in the process of consultation and treatment are wiped with chlorine-containing disinfectant at the end of treatment.
8, dental X-ray filming and rinsing: filming and rinsing X-rays should be barrier protection and surface disinfection. Barrier protection should be used when adjusting the position of the dental film shooter, adjusting control board parameters, and operating the machine. Gloves should be worn, and other protective measures such as masks, goggles, and gowns should be added if there is a possibility of splashing blood or body fluids.
When developing photographs in a darkroom: wipe saliva and blood from the film bag with a paper towel, open the film bag (dirty) in the darkroom, and allow the clean film inside to fall onto clean paper or a barrier to ensure that it does not contaminate the film. Wear a fresh pair of gloves for film processing.
When not using a darkroom to develop film: When not using a darkroom to develop film, more care is needed to prevent cross-contamination. Wrap the film bag with barrier material before shooting and remove the barrier material after shooting so that the clean film bag falls onto a clean surface. Re-wear a pair of gloves for subsequent processing.
9. Sterilization of handpieces: Most handpieces do not tolerate ultrasonic cleaning, but because oral debris/microorganisms may be sucked back into the interior of the handpiece lumen, the interior of the handpiece must be cleaned prior to sterilization.
