Course Summary:
In 2017 the World Workshop on Periodontology updated the 1999 classification on Periodontal diseases on Conditions and added a section to the classification on Peri-implant diseases and conditions. The goal of the Workshop was to establish case definitions and provide diagnostic criteria to use in the new classification. The objective of this course is to review the new 2017 classification and contrast it to the 1999 classification by Armitage and ways this classification affects categorizing periodontal diseases. The goal of the course is also to evaluate new ways of categorizing periodontal disease using “staging” and “grading” as well as review the current therapy that is available to treat periodontal and peri-implant diseases.
