The periodontology academies meet at certain times to review the scientific advances, according to which they modify the classification of periodontal diseases and conditions. In such a way, the classification of periodontal diseases from 1999 was valid for 18 years. In 2017 a global workshop was held sponsored by the American Academy of Periodontology and the European Federation of Periodontology, in which periodontal experts from all over the world met to update and present a new classification. They were all divided into four working groups: I. Periodontal health and gingival diseases and conditions; II. Forms of periodontitis; III. Periodontal manifestations of systemic diseases and developmental and acquired conditions; IV. Peri-implant diseases and conditions. The new classification -published in 2018-presents significant changes such as the definitions of periodontal health (for detection in clinical situations and epidemiological purposes) on an intact and reduced periodontium; the exclusion of chronic periodontitis and aggressive periodontitis, including them in the single term of periodontitis (determined through attachment loss and bone loss) categorized by stages (I, II, III and IV) and rates of progression (grades A, B or C); also the incorporation of peri-implant diseases and conditions. In addition, the new classification seeks to be helpful, practical, and flexible, with case definitions and diagnostic criteria to support the clinician in the treatment of their patients and allow both clinicians and researchers in any area to communicate with a common language. This paper aims to present the main definitions and parameters of each concept of the new classification for both students and clinicians in the first of two parts. Group I (Periodontal health and gingival diseases and conditions) and group II (Forms of periodontitis) will be addressed in this first part.
