The reference covers four broad areas. The first is the structure of the profession: what the recognised dental specialties are and how they differ. The second is procedures — fillings, root canal treatment, crowns, implants, orthodontics — explained step by step, with their purposes and limitations.
The third area is technology: digital imaging, CAD/CAM restorations, 3D printing, and related tools. The fourth is prevention and public health, where the evidence base is strongest. New topics are added when they can be explained accurately from authoritative sources.
