"Beyond the Label: Understanding Active Ingredients for Tailored Toothpaste Recommendations"
Ana Cecilia Aranha, DDS, MS
University of Sao Paulo, Brazil
Description: A wide range of toothpaste formulations with distinct active ingredients is available on the market — yet, clinical indications and chemical compositions often remain unclear to both patients and professionals. This lecture will guide dentists in navigating this complex scenario through evidence-based criteria. We will explore the main categories of active ingredients, fluoride types and concentrations, abrasivity levels, pH variation, and their impact on both dental tissues and restorative materials. More than understanding labels, the goal is to empower dentists to make personalized, strategic choices in toothpaste prescription, turning a routine habit into a powerful tool for prevention and oral health promotion.
Learning Objectives:
1) Identify and interpret the key active ingredients in toothpaste formulations, including their clinical indications, fluoride types, concentrations, pH, and abrasivity.
2) Apply evidence-based criteria to personalize toothpaste prescriptions according to individual patient needs, optimizing oral health outcomes and protecting restorative materials.

"Emerging Trends and Technological Advances in Dental Adhesive Technology"
Bart Van Meerbeek, DDS, PhD
KU Leuven, Leuven, Belgium
Description: Over the past three decades, dental adhesive technology has evolved from inconsistent clinical outcomes to a level of performance that may now approach its theoretical maximum. While it remains uncertain where exactly we stand on a scale of 0 to 100, current adhesives deliver unprecedented clinical reliability. This success invites a shift in focus toward added functionalities, particularly the integration of bioactivity, to be established without compromising primary bonding. Despite excellent everyday clinical performance, long-term data beyond 10 years remain scarce, and in-vitro models continue to reveal vulnerability to hydrolytic and enzymatic biodegradation. While endogenous MMPs have long been considered central to this process, recent evidence shows their activity rapidly declines post-bonding and is further suppressed by the chemical and thermal conditions of adhesive application. Maintaining a hydrophobic seal at the adhesive-dentin interface remains essential, providing protection against the absorption of water and exogenous enzymes from saliva and biofilms. The newest generation of universal adhesives allows clinicians to tailor bonding strategies to clinical conditions, for instance, preferentially employing an etch-and-rinse approach to bond to adhesion-challenging sclerotic or corroded dentin as found in cervical lesions or under aged amalgam restorations. Conversely, highly permeable dentin, such as that seen in patients with eating disorders, may require a gentler, self-etch strategy to minimally irritate the pulp and reduce sensitivity.
Learning Objectives:
1) Examine the current state and scientific underpinnings of dental adhesive technology,
2) Critically explore the mechanisms underlying bond degradation, and
3) Highlight emerging scientific trends that will shape the next generation of bioactive and durable adhesives.

"Optimizing Adhesive Luting Protocols for Ceramic Restorations"
Patricia Pereira, DDS. PhD
Professor, University of Florida, Gainesville, FL
Description: Optimizing adhesive luting protocols is essential to the long-term clinical success of ceramic restorations, as it directly impacts bond strength, durability, and resistance to functional aging. Evidence shows that factors such as surface treatments, material selection, preparation design, and luting techniques significantly influence clinical outcomes, with resin cements and luting protocols contributing to improved survival rates. In addition to restoration adaptation, proper bonding enhances marginal integrity, reduces failure rates, and supports esthetic longevity. However, challenges like technique sensitivity, hypersensitivity, and patient-specific variables require a case-by-case approach. A well-calibrated, evidence-based protocol remains critical to maximizing restoration performance in clinical practice.
Learning Objectives:
1) Identify factors that influence bond strength and long-term success of ceramic restorations
2) Describe current adhesive luting protocols for different types of ceramic restorations
3) Apply evidence-based guidelines to optimize luting procedures in clinical practice.
