High-yield notes
The desirable characteristic of classification system is that every disease should fall in at least one classes and no disease should fall into more than one of the classes.
The first person to differentiate periodontal diseases was Giralamo Cardono.
In 1880 the word "Pyorrhea alveolaris" was given by Gottlieb
In 1921 the word "Periodontosis" was given by Weski
In 1935 the word "Periodontopathy" was given by Weski
The International Workshop for the Classification of Periodontal Disease and Conditions - AAP 1999 (Ann Periodontol 1999, 4:1-7.) gave the word " Periodontitis "
