The guidance has been developed to aid the public health management of hepatitis A infection which aims to reduce the occurrence of secondary infections and to prevent and control outbreaks. The guidance has been developed based on a review of the current epidemiology of hepatitis A in England and a review of the literature on the efficacy of human normal immunoglobulin HNIG and hepatitis A vaccine for post-exposure prophylaxis.

News and Alerts: Infection Prevention and Control - Minnesota Dept. of Health
The new recommendations 3 emphasize the importance of having one person in every dental practice assigned to be the infection prevention coordinator. The coordinator would develop written infection prevention policies based on evidence-based guidance outlined in the new resource. The coordinator can help ensure that dental health care personnel are aware of the equipment and supplies necessary to address infection prevention issues with all staff members. The ADA has long advocated the use of infection control procedures in dental practice and provided dentists with resources to help them understand and implement them.
The ADA urges all practicing dentists, dental auxiliaries and dental laboratories to employ appropriate infection control procedures as described in the CDC Guidelines and CDC Summary and to keep up to date as scientific information leads to improvements in infection control, risk assessment, and disease management in oral health care. In April, , the CDC released a Statement on Reprocessing Dental Handpieces stressing that handpieces both low-speed and high-speed and other intraoral instruments that can be removed from the air lines and waterlines need to be heat sterilized between patients, 5, 6 and that reusable devices made prior to 6 may not meet current FDA reprocessing guidance.
If a dental handpiece cannot be heat sterilized and does not have FDA clearance with validated instructions for reprocessing, do not use that device. Chemical Indicators Use chemical indicators, such as indicator tapes, with each instrument load. These indicators change color after exposure to the proper sterilization environment.
Failure of the indicator to change color indicates that it was not exposed to the proper sterilization environment e.

In such cases, the instrument load should be re-sterilized. Indicator tapes are sterilizer-specific i. Chemical indicators should not replace biological indicators, as only a biological indicator consisting of bacterial endospores can measure the microbial killing power of the sterilization process.
Infection Control Statement
Biological Indicators The CDC recommends monitoring sterilizers at least weekly with biological indicators. Biological monitoring can be done in two ways: In-office incubator and spore monitoring strips contact your dental supplier for a list of products.
This method usually gives results in hours. Mail-in spore monitoring programs. This process usually takes a week. Although it takes longer to get results using a service, third-party monitoring programs may provide more accuracy than in-house monitoring. A positive spore test result indicates that sterilization failed.
According to CDC recommendations: 1, 3 Take the sterilizer out of service. Review the sterilization process being followed in the office to rule out operator error as the cause of failure.
NEJM Journal Watch
Correct any identified procedural problems, and retest the sterilizer using biological, mechanical, and chemical indicators. If the repeat biological indicator test is negative and the other test results fall within normal limits, the sterilizer can be returned to service.
Maintain a log of spore test results. Check with your state dental board to determine how long you need to keep spore testing records. If no procedural errors are identified or failures persist after procedural errors are corrected, the sterilizer should not be used until the reason for failure has been identified and corrected. To the extent possible, reprocess all instruments that were sterilized since the last negative spore test. Record the positive test results and all actions taken to help ensure proper functioning of the sterilizer in the monitoring log.
