The pathogenesis is the sequence of events that occur during the development of any disease or abnormal condition. Periodontal, exists in three main conditions: health, gingivitis
and periodontitis (Fig. 3-1 and 3-2). It is important to understand the differences between health, gingivitis and periodontitis (table. 3-1). This section provides an overview of the three main States in clinical and microscopic levels.
The term " periodontal disease, not to be confused with the term of periodontitis. Gingivitis and periodontitis are two main categories of periodontal disease. Gingivitis is a bacterial infection that comes down to the gum. Tissue damage that occurs in gingivitis results in reversible destruction of periodontal tissues (Fig. 3-3).
