Digital Dentistry for Dental Hygienists: Embracing the Future of Oral Healthcare

Susan Woodley, RDH

As digital technologies redefine modern dental care, dental hygienists are uniquely positioned to lead and support the integration of innovation into everyday practice. This course is designed to empower dental hygienists with the knowledge and hands-on skills needed to confidently engage with intraoral scanning, discover how new technologies can enhance clinical accuracy, improve client education, and streamline workflow collaboration within the dental team.

By the end of this course, participants will be able to:

Understand the role and impact of intraoral digital scanning in modern dentistry
Identify opportunities for incorporating digital workflows into their daily practice
Apply “Best Practice” digital techniques to enhance accuracy, efficiency, and client experience
Promote patient engagement and increased case acceptance through digital education platforms

Securing Smiles: Cybersecurity for Healthcare

Dani Amanouail, RDH

Dental practices are increasingly becoming targets for cybercriminals due to the high value of electronic health records (EHR), financial data, and insurance records. A single cyber incident can disrupt patient care, compromise sensitive data, damage professional reputation, and result in regulatory penalties.

My goal is to provide dental professionals with a practical, non-technical understanding of today’s most common cybersecurity threats impacting dental settings. Attendees will learn how ransomware, phishing, insider threats, and weak office IT practices affect daily operations — and more importantly, how to reduce risk using realistic, cost-effective strategies.

Drawing from both years of clinical experience and cybersecurity expertise, this presentation bridges the gap between oral healthcare and digital protection, empowering dental hygienists and practice owners to strengthen security, safeguard patient trust, and build resilient practices against threats.

Learning Objectives

Identify the most common cybersecurity threats affecting dental practices, including phishing, ransomware, and data breaches.
Recognize how human error contributes to security incidents within clinical and administrative workflows.
Implement practical, cost-effective safeguards to reduce cyber risk in a dental office environment.
Understand the regulatory and professional implications of failing to protect patient information.
Apply basic incident response steps in the event of a suspected cyberattack.

Targeted Supplementation and Nutrition for Periodontal and Systemic Health

Lorraine Gambacourt, RDH

Periodontitis is a chronic inflammatory disease driven not only by bacteria, but by an exaggerated inflammatory host response that can lead to connective tissue destruction, bone loss, and increased systemic inflammatory burden throughout the body. Nutrition plays an important role in the maintenance of periodontal health, however many individuals do not consistently consume optimal levels of key nutrients required to support healing, immune function, inflammation regulation, and periodontal stability. Deficiencies can exacerbate periodontal tissue damage.

This course will review a variety of vitamins, minerals and nutrients that play important roles in immune function, inflammation regulation, antioxidant defense, and tissue repair.

Learning Objectives:

1. Explain how inflammation and the host response affect periodontal and systemic health.

2. Identify supplements that may support periodontal healing, bone health, and inflammation control.

3. Evaluate current evidence supporting supplementation in periodontal therapy.

4. Differentiate supplementation approaches for periodontitis, maintenance, and peri-implant care.

5. Apply supplementation and nutritional discussions in client education and clinical practice.

Beyond the Scaler: Advancing Periodontal Therapy with Adjunctive Innovation

Chrissy Ford, RDH, BScDH

Modern periodontal care extends far beyond scaling and root planning! The tools and strategies available to dental hygienists have never been more powerful. This dynamic session explores adjunctive therapies that enhance healing, reduce inflammation, and elevate clinical outcomes beyond traditional instrumentation.

Through clinical examples and treatment planning frameworks, dental hygienists will learn how to confidently select and communicate these therapies for maximum impact-improving both patient health and practice success.

Learning Objectives

1. Identify clinical indicators for incorporating adjunctive therapies into periodontal treatment plans.

2. Understand the science and practical application of air polishing, desiccation therapy, hydrogen peroxide treatment, and oral inflammation testing.

3. Integrate adjunctive therapies confidently into clinical protocols to enhance healing and reduce inflammation.

4. Communicate the value of adjunctive periodontal care to improve patient understanding and case acceptance.
