title: Classification of periodontal diseases: where were we? Where are we now? Where are we going?
abstract: This paper discusses the past, present and possible future classification of periodontal diseases. It outlines the reasons for using a classification system from a clinical perspective and provides a critical appraisal of the latest classification. The major changes introduced in the 1999 system are discussed alongside the rationale behind the recommended nomenclature.
