He was a French physician considered the father of modern dentistry.
In 1728, he authored “Le Chirurgien Dentiste” (Surgical Dentistry), the first handbook on dentistry. In his work, he described basic oral anatomy and function, the signs and symptoms of oral pathology, surgical methods for treating cavities and restoring teeth, periodontal disease (piorrhea), orthodontics, the replacement of missing teeth, and tooth transplantation, and it served as a standard reference work for many years.
