608 Dental Office Safety

Glossary

A

• Aerosol-Generating Procedures (AGPs). Dental procedures that produce aerosols containing saliva, blood, and other particles, increasing the risk of airborne disease transmission. Examples include ultrasonic scaling, high-speed drilling, and air polishing.
• Aseptic Technique. A set of practices aimed at minimizing the risk of introducing harmful microorganisms during dental procedures. It includes sterilization, disinfection, and maintaining a sterile field.

B

• Bioburden. The microbial load or organic material (e.g., blood, saliva) on instruments or surfaces before sterilization. Proper cleaning prior to sterilization reduces bioburden and enhances sterilization efficacy.
• Biological Monitoring. The process of testing sterilizers, such as autoclaves, to ensure effective sterilization of instruments by using biological indicators (e.g., spore tests). This helps confirm that pathogens are eliminated.
• Bloodborne Pathogens. Infectious microorganisms present in human blood that can cause diseases such as hepatitis B (HBV), hepatitis C (HCV), and human immunodeficiency virus (HIV). Dental offices are required to follow OSHA's Bloodborne Pathogens Standard, including annual training for employees.

C

• Chemical Disinfection. The use of EPA-registered disinfectants to clean surfaces and instruments that cannot be heat-sterilized. These chemicals are effective against a broad range of pathogens, including bacteria and viruses.
• Chemical Spill Protocol. Procedures for responding to spills of hazardous chemicals, such as cleaning solutions or dental materials, including containment, cleanup, and disposal in accordance with OSHA and EPA guidelines.
• Cross-Contamination. The unintentional transfer of harmful microorganisms between patients, staff, instruments, and surfaces. Preventive measures include proper hand hygiene, surface disinfection, and sterilization protocols.

D

E

• Emergency Action Plan (EAP). A written plan required by OSHA that outlines procedures for dental staff to follow in the event of emergencies such as fire, medical emergencies, or chemical spills.
• Ergonomics in Dentistry. The application of ergonomic principles to reduce strain, prevent musculoskeletal disorders (MSDs), and improve posture during dental procedures. Strategies include proper chair positioning, instrument design, and frequent breaks.
• Exposure Control Plan. A required OSHA document detailing the measures dental offices take to protect employees from exposure to bloodborne pathogens and other infectious agents. It must include hazard identification, training, and post-exposure protocols.

F

• Fire Safety in Dental Offices. Procedures to prevent and respond to fires, including maintaining fire extinguishers, conducting fire drills, and ensuring clear access to emergency exits.
• Flushing Waterlines. A preventive maintenance practice to reduce biofilm and bacteria in dental unit waterlines by running water or chemical cleaners through them before and after patient care.

G

• Gas Detection. The use of instruments to monitor and identify hazardous gases in a confined space, such as toxic or flammable gases. Continuous gas detection is crucial for worker safety.

H

• Hand Hygiene. Practices such as handwashing with soap and water or using alcohol-based hand sanitizers to prevent the transmission of infectious agents. Hand hygiene is a cornerstone of infection control in dental settings.
• Hazard Communication (HAZCOM). An OSHA standard requiring dental offices to inform employees about chemical hazards through training, labeling, and access to safety data sheets (SDS).
• Hazardous Waste Management. Proper handling and disposal of hazardous materials, such as used disinfectants, amalgam waste, and sharps, in compliance with EPA and local regulations.

I

• Infection Control. Comprehensive protocols designed to prevent the transmission of infectious diseases in dental settings. These include sterilization, disinfection, proper waste disposal, and use of personal protective equipment (PPE).
• Instrument Cassettes. Organizers used to group and protect dental instruments during cleaning, sterilization, and storage, minimizing handling and reducing risk of contamination.

J

K

L

• Latex Allergy Safety. Protocols to protect patients and staff with latex allergies by using latex-free gloves and equipment and ensuring alternatives are available.
• Laundry Management. Procedures for handling and cleaning reusable gowns, lab coats, and other textiles to prevent cross-contamination, typically involving separate containers for soiled and clean items.

M

• Medical Waste Management. Proper handling, segregation, and disposal of regulated waste such as sharps, blood-contaminated items, and tissue samples, in compliance with local and federal regulations.
• Mercury Safety. Protocols for handling dental amalgam containing mercury to minimize exposure risks for dental workers and patients, and to prevent environmental contamination.

N

O

P

• Pathogen Transmission. The process by which harmful microorganisms, such as bacteria and viruses, spread in dental settings via aerosols, contact with contaminated surfaces, or direct patient contact.
• Personal Protective Equipment (PPE). Protective clothing and equipment, such as gloves, masks, face shields, and gowns, used to minimize exposure to infectious agents and hazardous chemicals.
• Post-Exposure Prophylaxis (PEP). A treatment protocol administered after exposure to bloodborne pathogens, such as needlestick injuries, to reduce the risk of infection.

Q

• Qualified person. One who, by possession of a recognized degree, certificate, or professional standing, or who by extensive knowledge, training, and experience, has successfully demonstrated his ability to solve or resolve problems relating to the subject matter, the work, or the project.

R

• Radiation Safety Protocols. Guidelines to protect dental workers and patients from excessive exposure to X-rays, including the use of lead aprons, thyroid collars, and proper shielding.
• Respiratory Protection. Use of masks and respirators, such as N95 respirators, to prevent the inhalation of infectious aerosols and chemical fumes generated during dental procedures.

S

• Sharps Safety. Procedures to prevent injuries from sharp instruments, such as needles and scalpel blades. This includes the use of safety-engineered devices and proper disposal in puncture-resistant containers.
• Single-Use Devices (SUDs). Items designed for one-time use, such as disposable needles, gloves, and syringes, to prevent cross-contamination and ensure patient safety.
• Surface Disinfection. Cleaning and disinfecting environmental surfaces in dental operatories between patients to eliminate pathogens and reduce infection risk. EPA-registered disinfectants are used.

T

• Training Requirements. OSHA-mandated training for dental staff on infection control, chemical safety, bloodborne pathogens, and emergency procedures. Training must be provided annually and thoroughly documented.

U

V

• Vaccination Policies. Recommendations for dental professionals to receive vaccinations, such as hepatitis B, influenza, and COVID-19, to prevent occupational exposure to infectious diseases.
• Ventilation in Dental Offices. The use of proper ventilation systems, including high-efficiency particulate air (HEPA) filters and local exhaust systems, to reduce airborne contaminants during procedures.
• Waterline Contamination. The buildup of biofilms and bacteria in dental unit waterlines, which can pose infection risks if not managed through regular flushing and maintenance.

W

• Workplace Violence Prevention. Strategies to address and prevent violence in dental offices, including training on conflict resolution and maintaining secure environments for staff and patients.
