Over the years, periodontal diseases and conditions have been classified in a variety of ways.1 This system of classification is used as a means to properly diagnose and treat individuals with periodontal problems. The etiology of the systemic diseases, prevalence and incidence, microbiology, manifestations of the disease, oral symptoms and the possible therapeutic approaches will be discussed. Reconnecting Practicing Hygienists with the Nation's Leading Educators and Researchers. Dietrich et al. This introductory overview presents the schematic tables for the new classification of periodontal and peri‐implant diseases and conditions and briefly highlights changes made to the 1999 classification.

The classification presented in this chapter is based on the most recent internationally accepted consensus opinions of the diseases and conditions that affect the tissues of the periodontium; it was presented and discussed at the 1999 International Workshop for the Classification of the Periodontal Diseases organized by the American Academy of Periodontology (AAP). 1 Subsequently, a simpler classification was agreed upon at the 1 st European Workshop in Periodontology.

At that workshop, the following classifications for periodontal diseases were introduced: o Adult periodontitis The last time scientists and clinicians in the field of periodontology and related areas agreed upon a classification system for periodontal diseases was in 1989 at the World Workshop in Clinical Periodontics. In 1989, a classification system was proposed that included five types of periodontitis: adult periodontitis, early onset periodontitis, periodontitis associated with systemic disease, necrotizing ulcerative periodontitis, and refractory periodontitis.2 This system was widely used among practitioners although a gingival disease component was missing and there was an overlap of disease categories.3 In addition, some criteria appeared to be unclear or inadequate.3 Given that changes were needed, in 1999, the classification system for periodontal diseases and conditions was updated. Oral health professionals have an opportunity to use this model to increase consistency in diagnosing periodontal conditions and educating patients on their periodontal treatment needs. 1999.

The classification includes systemic modifying factors thus recognizing the role of factors such as diabetes and smoking on the onset and progression of periodontal disease.
