- Dental assistants typically spend more time handling and processing contaminated instruments. (correct)
- Dental assistants are generally less experienced and trained in handling sharp instruments compared to dentists.
- Dentists are less likely to report injuries due to concerns about their professional reputation.

Study Notes
Infection Control
- Infection control involves practices, procedures, and policies designed to prevent the spread of infectious agents.
- Infectious agents include bacteria, viruses, fungi, and parasites.
- Infection control aims to protect healthcare providers and patients from acquiring and transmitting infections.
Regulation of infection control
- Global and regional organizations include:
- World Health Organization (WHO)
- Centers for Disease Control and Prevention (CDC)
- American Dental Association (ADA)
- Local Organizations include:
- Ministry of Health and Prevention (MOHAP)
- Department of Health (DOH)
- Dubai Health Authority (DHA)
Dental Setting Routes of Transmission
- Bloodborne Route: Transmission occurs through exposure to infected blood or body fluids, such as Hepatitis B, Hepatitis C, and HIV.
- Salivary Route: Transmission occurs through contact with saliva containing infectious pathogens like HSV and CMV.
- Aerosol and Droplet Route: Generated during high-speed handpiece use, ultrasonic scaling, or air-water syringes.
- Contact Route: Transmission occurs by touching contaminated instruments, surfaces, or hands and transferring the pathogen to mucous membranes or skin.
Common Diseases Transmitted in Dental Settings
- Bloodborne Transmission:
- Hepatitis B (HBV)
- Hepatitis C (HCV)
- HIV/AIDS
- Salivary Transmission:
- Herpes Simplex Virus (HSV)
- Cytomegalovirus (CMV)
- Candidiasis (e.g., Candida albicans)
- Aerosol and Droplet Transmission:
- Tuberculosis (TB)
- Influenza
- COVID-19
Standard Precautions and Cross-Contamination Prevention
- Hand Hygiene: Regular handwashing or use of alcohol-based hand rubs before and after patient contact.
- Use of Personal Protective Equipment (PPE): Gloves, masks, protective eyewear, face shields, and gowns prevent exposure to blood, saliva, and other body fluids.
- Instrument Sterilization: Cleaning, sterilizing, and maintaining all reusable instruments.
- Cleaning and Disinfection: Proper cleaning and disinfection of surfaces and equipment between patients.
- Safe Disposal of Sharps: Proper disposal of sharp instruments like needles, syringes, and blades in sharps containers.
- Treat all patients as infectious.
Infection Exposure
- A study in Florianópolis, Brazil, found that 94.5% of dentists and 80.8% of dental assistants reported occupational exposures to potentially infectious materials.
- Both groups reported similar exposure rates of approximately 39% in the year preceding the study.
- Percutaneous injuries were more frequent among dental assistants (95.2%) compared to dentists (60.7%).
Occupational infections in Health Workers
- Research indicates that dental health workers (DHW) are at increased risk of acquiring occupational infections.
- A study analyzing data from a German accident insurance company reported 271 claims of occupational diseases among DHWs from 2006 to 2019, with 112 confirmed cases, averaging eight per year.
- The World Health Organization (WHO) reports that needlestick injuries contribute to 37% of hepatitis B, 39% of hepatitis C, and 4.4% of HIV infections among healthcare workers.
- The prevalence of acute hepatitis B infection among health workers globally is 5.3%.
- Approximately 54% of health workers in low- and middle-income countries have latent tuberculosis infections.
