Fluoride in Dentistry: Science and Mechanisms

Fluoride is one of the most effective agents in preventing dental caries. Its unique mechanisms of action, including inhibiting enamel demineralisation, promoting remineralisation, and reducing bacterial acid production, make it indispensable in modern dental practice.

This course looks into the chemistry, microbiology, histological effects, and clinical applications of fluoride in dentistry. It also looks at systemic considerations, safety thresholds, and advances in fluoride delivery systems. Whether you are a dental professional or student, this course will enhance your knowledge and improve your clinical decision-making when using fluoride treatments.

Fluoride is essential for preventing dental caries, especially in high-risk patients. Its benefits are realised through careful application, understanding its systemic and topical effects, and tailoring interventions based on patient needs.

The topics covered in this course include:

The chemistry of fluoride and its interactions with enamel and dentine.
Fluoride’s role in remineralisation, demineralisation, and its antibacterial properties.
The microbiological impact of fluoride on oral biofilms and cariogenic bacteria.
Histological effects of fluoride, including its incorporation during tooth development and post-eruptive changes.
Fluoride-containing materials and their mechanisms of sustained release.
Systemic fluoride absorption, metabolism, and safety thresholds.
Clinical applications of fluoride, including varnishes, gels, and custom regimens based on caries risk.

By the end of this course, you will have a comprehensive understanding of fluoride's mechanisms and clinical applications, enabling evidence-based practice and improved patient outcomes.
