Learning Objectives: 

• Compare the mechanisms of action of fluoride and nano-hydroxyapatite in caries prevention and remineralization.
• Evaluate current clinical evidence supporting n-HAp for sensitivity reduction and enamel repair.
• Design a patient-centered remineralization protocol integrating n-HAp into preventive care.
• Critically appraise product claims and educate patients seeking fluoride alternatives.

For the last 80 years fluoride has been the gold standard in caries prevention. Yet, with increasing demand for holistic, nontoxic and biocompatible oral care solutions, nano-hydroxyapatite (n-HAp) has emerged the leading powerful alternative with promising results in enamel repair, remineralization, and dentin sensitivity reduction This course critically explores the science, safety, and efficacy of n-HAp, comparing its mechanisms to fluoride and presenting real-world protocols for clinical integration. Attendees will examine peer-reviewed evidence, evaluate patient-centered case studies, and explore how to design and apply a stepwise remineralization protocol incorporating n-HAp into preventive care Interactive activities, product comparisons, and evidence-based discussion will equip participants to confidently navigate patient questions, assess product claims, and integrate n-HAp into individualized care plans. By the end, hygienists will be able to offer patients fluoride alternatives rooted in research, not hype.
