This work presents a broad historical perspective on the evolution of periodontics from the prehistoric era to the present. Along the way, it highlights key figures and their contributions to our contemporary understanding and treatment of periodontal disease. Emphasizing periodontology's roots in the medical sciences, the book traces the impact of several landmark 19th-century discoveries - such as germ theory of disease, anaesthesia and X-rays - on modern periodontics. Half of the book focuses on emerging concepts of the 20th century. Details about the lives of well-known periodontal pioneers and ample quotes reveal the medical and scientific beliefs of the times. The text should lend clarity to the past and insight into the future of periodontics.
