Periodontology, a field of dentistry, has achieved unprecedented significance and popularity in recent times. Advances in research, diagnostic methods, and technological enhancements have transformed the landscape of periodontics, elevating its role in comprehensive treatment approaches.

In alignment with unified educational programs, the international educational standard emphasizes the creation of relevant books tailored for these programs. Notably, recent years have witnessed a positive trend in the publication of high-quality periodontology books.

As authors of this book, we deemed it fitting to base our work on the international classification of periodontal diseases established at the 1999 International Symposium organized by the American Academy of Periodontology. This classification, widely utilized in the USA and many European countries, serves as a foundation in both educational and clinical practices.

The first part of the book, titled "Basic and Clinical Periodontology," draws upon guidelines developed from international and national experiences. A seamless amalgamation of cutting-edge technologies and the intellectual contributions of American and European Schools, the book features illustrations depicting clinical cases from foreign specialists and our own center, Albius.

Primarily designed for postgraduate education—PhD candidates, residents, and dentists specializing in periodontology—the present book represents only the initial segment. It extensively covers the historical background of various classifications of periodontal diseases, including those from Europe and the USA, ICD diseases, international health condition statistics, the Soviet Union, and the Russian Federation. Topics span clinical anatomy of periodontal tissues, histology and embryogenesis, innervation, blood supply and lymphatic systems, etiology and pathogenesis, clinic of periodontal diseases, modern diagnostic methods, and epidemiology of periodontal diseases.

The second part of the book delves deeply into the role of evidence-based medicine in modern periodontology, encompassing both surgical and non-surgical methods of periodontal diseases, the fundamentals of plastic periodontal microsurgery, peri-implantitis, and treatment characteristics.

Narrating evidence-based issues in an engaging manner for active practitioners was a significant challenge for us, the authors. We believe this aspect is crucial in captivating the interest of readers. We trust that the first part of "Basic and Clinical Periodontology" will be a valuable resource for specialists in the field.

Ilia State University, the International PerioSchool of the Dental Center Albius and the Georgian Dental Association extend their best wishes for success to professionals in periodontology. This book aims to modestly contribute to the enhancement of their professional education and clinical skills.
