Although the infection-control coordinator remains responsible for overall management of the program, creating and maintaining a safe work environment ultimately requires the commitment and accountability of all dhcp. This report is designed to provide guidance to dhcp for preventing disease transmission in dental health-care settings, for promoting a safe working environment, and for assisting dental practices in developing and implementing infection-control programs. These programs should be followed in addition to practices and procedures for worker protection required by the Occupational Safety and health Administration's (osha) standards for occupational exposure to bloodborne pathogens ( 13 including instituting controls to protect employees from exposure to blood or other potentially. Interpretations and enforcement procedures are available to help dhcp apply this osha standard in practice ( 14 ). Also, manufacturer's Material Safety data Sheets (msds) should be consulted regarding correct procedures for handling or working with hazardous chemicals ( 15 ). Previous Recommendations This report includes relevant infection-control measures from the following previously published cdc guidelines and recommendations: cdc. Guideline for disinfection and sterilization in health-care facilities: recommendations of cdc and the healthcare Infection Control Practices Advisory committee (hicpac). Guidelines for environmental infection control in health-care facilities: recommendations of cdc and the healthcare Infection Control Practices Advisory committee (hicpac).

Dhcp should be familiar also with the hierarchy of controls that categorizes and prioritizes prevention strategies ( 12 ). For bloodborne pathogens, engineering controls that eliminate or isolate the hazard (e.g., puncture-resistant sharps containers or needle-retraction devices) are the primary strategies for protecting dhcp and patients. Where engineering controls are not available or appropriate, work-practice controls that result in safer behaviors (e.g., one-hand needle recapping or not using fingers for cheek retraction while using sharp instruments or suturing and use of personal protective equipment (PPE) (e.g., protective eyewear, gloves, and mask). In addition, administrative controls (e.g., policies, procedures, and enforcement measures targeted at reducing the risk of exposure to infectious persons) are a priority for certain pathogens (e.g.,. Tuberculosis particularly those spread by airborne or droplet routes. Dental practices dream should develop a written infection-control program to prevent or reduce the risk of disease transmission. Such a program should include establishment and implementation of policies, procedures, and practices (in conjunction with selection and use of technologies and products) to prevent work-related injuries and illnesses among dhcp as well as health-care-associated infections among patients. The program should embody principles of infection control and occupational health, reflect current science, and adhere to relevant federal, state, and local regulations and statutes. An infection-control coordinator (e.g., dentist or other dhcp) knowledgeable or willing to be trained should be assigned responsibility for coordinating the program. The effectiveness of the infection-control program should be evaluated on a day-to-day basis and over time to help ensure that policies, procedures, and practices are useful, efficient, and successful (see program evaluation).
The relevance of universal precautions to other aspects of disease transmission was recognized, and in 1996, cdc expanded the concept and changed the term to standard precautions. Standard precautions integrate and expand the elements of universal precautions into a standard of care designed to protect hcp and patients from pathogens that can be spread by blood or any other body fluid, excretion, or secretion ( 11 ). Standard precautions apply to contact remote with 1) blood; 2) all body fluids, secretions, and excretions (except sweat regardless of whether they contain blood; 3) nonintact skin; and 4) mucous membranes. Saliva has always been considered a potentially infectious material in dental infection control; thus, no operational difference exists in clinical dental practice between universal precautions and standard precautions. In addition to standard precautions, other measures (e.g., expanded or transmission-based precautions) might be necessary to prevent potential spread of certain diseases (e.g., tb, influenza, and varicella) that are transmitted through airborne, droplet, or contact transmission (e.g., sneezing, coughing, and contact with skin) (. When acutely ill with these diseases, patients do not usually seek routine dental outpatient care. Nonetheless, a general understanding of precautions for diseases transmitted by all routes is critical because 1) some dhcp are hospital-based or work part-time in hospital settings; 2) patients infected with these diseases might seek urgent treatment at outpatient dental offices; and 3) dhcp might become. Necessary transmission-based precautions might include patient placement (e.g., isolation adequate room ventilation, respiratory protection (e.g., n-95 masks) for dhcp, or postponement of nonemergency dental procedures.
Dental patients and dhcp can be exposed to pathogenic microorganisms including cytomegalovirus (cmv hbv, hcv, herpes simplex virus types 1 and 2, hiv, mycobacterium tuberculosis, staphylococci, streptococci, and other viruses and bacteria that colonize or infect the oral cavity and respiratory tract. These organisms can be transmitted in margaret dental settings through 1) direct contact with blood, oral fluids, or other patient materials; 2) indirect contact with contaminated objects (e.g., instruments, equipment, or environmental surfaces 3) contact of conjunctival, nasal, or oral mucosa with droplets (e.g., spatter) containing. Infection through any of these routes requires that all of the following conditions be present: a pathogenic organism of sufficient virulence and in adequate numbers to cause disease; a reservoir or source that allows the pathogen to survive and multiply (e.g., blood a mode. Occurrence of these events provides the chain of infection ( 6 ). Effective infection-control strategies prevent disease transmission by interrupting one or more links in the chain. Previous cdc recommendations regarding infection control for dentistry focused primarily on the risk of transmission of bloodborne pathogens among dhcp and patients and use of universal precautions to reduce that risk ( 1, 2, 7, 8 ). Universal precautions were based on the concept that all blood and body fluids that might be contaminated with blood should be treated as infectious because patients with bloodborne infections can be asymptomatic or unaware they are infected ( 9, 10 ). Preventive practices used to reduce blood exposures, particularly percutaneous exposures, include 1) careful handling of sharp instruments, 2) use of rubber dams to minimize blood spattering; mini 3) handwashing; and 4) use of protective barriers (e.g., gloves, masks, protective eyewear, and gowns).
Some infection-control practices routinely used by health-care practitioners cannot be rigorously examined for ethical or logistical reasons. In the absence of scientific evidence for such practices, certain recommendations are based on strong theoretical rationale, suggestive evidence, or opinions of respected authorities based on clinical experience, descriptive studies, or committee reports. In addition, some recommendations are derived from federal regulations. No recommendations are offered for practices for which insufficient scientific evidence or lack of consensus supporting their effectiveness exists. Background, in the United States, an estimated 9 million persons work in health-care professions, including approximately 168,000 dentists, 112,000 registered dental hygienists, 218,000 dental assistants ( 3 and 53,000 dental laboratory technicians ( 4 ). In this report, dental health-care personnel (dhcp) refers to all paid and unpaid personnel in the dental health-care setting who might be occupationally exposed to infectious materials, including body substances and contaminated supplies, equipment, environmental surfaces, water, or air. Dhcp include dentists, dental hygienists, dental assistants, dental laboratory technicians (in-office and commercial students and trainees, contractual personnel, and other persons not directly involved in patient care but potentially exposed to infectious agents (e.g., administrative, clerical, housekeeping, maintenance, or volunteer personnel). Recommendations in this report are designed to prevent or reduce potential for disease transmission from patient to dhcp, from dhcp to patient, and from patient to patient. Although these guidelines focus mainly on outpatient, ambulatory dental health-care settings, the recommended infection-control practices are applicable to all settings in which dental treatment is provided.

Recommendations are provided regarding 1) educating and protecting dental health-care personnel; 2) preventing transmission of bloodborne pathogens; 3) hand hygiene; 4) personal protective equipment; 5) contact dermatitis and latex hypersensitivity; 6) sterilization and disinfection of patient-care items; 7) environmental infection control; 8) dental unit waterlines. These recommendations were developed in collaboration with and after review by authorities on infection control from cdc and other public agencies, academia, and private and professional organizations. This report consolidates recommendations for preventing and controlling infectious diseases and managing personnel health and safety concerns related to infection control in dental settings. This report 1) updates and revises previous cdc recommendations regarding infection control in dental settings ( 1, 2 2) incorporates relevant infection-control measures from other cdc guidelines; and 3) discusses concerns not addressed in previous recommendations for dentistry. These updates and additional topics include the following: application of standard precautions rather than universal precautions; work restrictions for health-care personnel (HCP) infected with or occupationally exposed to infectious diseases; management of occupational exposures to bloodborne pathogens, including postexposure prophylaxis (PEP) for work exposures. These guidelines were developed by cdc staff members in collaboration with other authorities on infection control.
Draft documents were reviewed by other federal agencies and professional organizations from the fields of dental health care, public health, and hospital epidemiology and infection control. Federal Register notice elicited public comments that were considered in the decision-making process. Existing guidelines and published research pertinent to dental infection-control principles and practices were reviewed. Wherever possible, recommendations are based on data from well-designed scientific studies. However, only a limited time number of studies have characterized risk factors and the effectiveness of prevention measures for infections associated with dental health-care practices.
