Waterline Safety

$10.00

Course Overview

Dental unit waterlines (DUWLs) play a vital role in modern dentistry, delivering water for irrigation, cooling, and rinsing during procedures. Despite their importance, waterlines represent one of the most significant microbiological challenges in dental practice. The narrow-bore plastic tubing, intermittent water flow, and ambient water temperature create an ideal environment for the development of microbial biofilms. Over time, these biofilms can harbor bacteria, fungi, and protozoa that may pose serious risks to both patients and dental staff.

The importance of maintaining clean and safe dental waterlines extends beyond infection control, it reflects the profession’s ethical responsibility to provide care that meets the highest standards of safety and quality. The Centers for Disease Control and Prevention (CDC) and the American Dental Association (ADA) have established clear recommendations regarding waterline maintenance and acceptable microbial levels. However, studies continue to show that without consistent protocols, waterline contamination can quickly exceed these standards, sometimes reaching bacterial counts similar to those found in stagnant tap water or untreated environmental sources.

This course is designed to provide dental professionals with the knowledge and tools needed to understand, monitor, and maintain waterline safety. Participants will explore the microbiological basis of contamination, the risks posed by biofilms, and the evidence-based practices required to keep dental unit water systems compliant and safe for patient care.

Learning Objectives

Explain how microbial contamination develops and persists in dental unit waterlines.
Describe the composition and behavior of biofilms within DUWL systems.
Identify the major water-quality standards and guidelines established by the CDC, ADA, and EPA.
Recognize the potential health risks associated with exposure to contaminated dental water.
Discuss methods for testing, monitoring, and evaluating waterline microbial quality.
Understand the factors influencing contamination, including system design and maintenance practices.
Apply evidence-based principles to develop an effective waterline safety protocol.

2 Hour Infection Control

$10.00|2.0 CEU|120 min

Course Overview

Infection control is a foundational responsibility in dental practice, directly impacting the safety of patients, clinicians, and auxiliary staff. This course provides a comprehensive review of current infection control principles as they apply to dentistry, including the science of disease transmission, the hierarchy of disinfection and sterilization, and the classification of instruments and clinical surfaces. Participants will gain a clear understanding of key pathogens of concern in the dental setting—such as Mycobacterium tuberculosis, hepatitis viruses, and HIV—and the rationale for core protective measures, including immunization against Hepatitis B and strict adherence to standard precautions.

Building on these fundamentals, the course offers detailed, step-by-step guidance on implementing aseptic technique throughout the dental office and laboratory. Topics include appropriate use of personal protective equipment, hand hygiene protocols, operatory setup and turnover, instrument processing workflows, and the selection and use of chemical disinfectants. Special attention is given to the sterilization and maintenance of handpieces, management of suction systems and dental unit waterlines, safe handling of radiographic equipment and impression materials, and proper segregation, treatment, and disposal of contaminated waste in compliance with regulatory standards.

Finally, the course addresses the ethical and legal dimensions of infection control, particularly as they relate to the care of patients with HIV and other infectious diseases. Real-world case law is reviewed to clarify professional obligations, anti-discrimination requirements, and the importance of consistent, documented protocols. The curriculum concludes with practical office and laboratory checklists, along with strategies for communicating infection control procedures effectively to patients and team members, ensuring both regulatory compliance and a high level of trust and confidence in the dental environment.

Learning Objectives

After completing this course, participants will be able to:

Define and accurately use key infection control terminology, including sterilization, disinfection, standard precautions, critical and semi-critical instruments, and levels of disinfection.
Describe the modes of transmission and clinical significance of major pathogens relevant to dentistry, including Mycobacterium tuberculosis, hepatitis B and C viruses, and HIV.
Explain the rationale for Hepatitis B vaccination in dental personnel and outline appropriate post-exposure management and follow-up.
Select and correctly utilize personal protective equipment (PPE)—including gloves, masks, protective eyewear, and clinical attire—based on the procedure and anticipated exposure risk.
Implement evidence-based protocols for operatory asepsis, including surface barriers, environmental surface disinfection, management of spills, and regulated waste handling in compliance with local regulations.
Design and maintain an effective instrument processing workflow, from presoak and ultrasonic cleaning through packaging, sterilization, and biological monitoring (spore testing) for various sterilization methods.
Apply appropriate aseptic techniques for high-speed and slow-speed handpieces, air/water syringes, ultrasonic scalers, impression materials, radiographic equipment, and evacuation systems.
Describe best practices for infection control in the dental laboratory, including handling of incoming and outgoing cases, pumice and rag wheel management, and communication of disinfection responsibilities between office and lab.
Summarize current recommendations and regulatory expectations for dental unit waterline quality, including CFU/mL targets and options for flushing, chemical treatment, and filtration.
Interpret the ethical and legal obligations related to treating patients with HIV and other infectious diseases and integrate these requirements into practice policies, documentation, and patient communication.

Advances in Dentistry
