Infection Control, Sterilization, and Clinical Safety Standards
Infection control is critical in dental practice to prevent transmission of infectious diseases. Alabama Board rules adopt standards similar to CDC and OSHA guidelines. Key concepts include standard precautions (treating all patients as potentially infectious), hand hygiene, use of personal protective equipment (PPE) such as gloves, masks, eyewear, and gowns, and safe handling of sharps. Sterilization of instruments requires autoclaving or other approved methods, with monitoring (e.g., spore testing) and proper storage. Surface disinfection and barriers are required for clinical contact surfaces. Dental unit waterlines must be maintained to meet quality standards. Traps include confusing disinfection with sterilization, or forgetting that spore testing is required for sterilizers. Rule of thumb: if an item penetrates soft tissue or bone, it must be sterile; if it contacts mucous membranes, it must be disinfected at a minimum. Example: A dental assistant must wear gloves when handling contaminated instruments, and instruments must be autoclaved and stored in sterile pouches. Another trap is assuming that infection control is only for dentists; all team members must comply. The Board may inspect offices and discipline licensees for violations. Also, needlestick protocols and HBV vaccination are part of safety standards. Candidates should know that infection control violations can lead to license suspension. Always follow current CDC guidelines and Board rules. Remember that handpieces and other items that contact oral tissues must be sterilized between patients. Waterlines require regular flushing and treatment. These details are frequently tested.
