I. Gingivitis associated with dental plaque only A. Without local contributing factors B. With local contributing factors These factors are contributory because of their ability to retain plaque microorganisms and inhibit their removal by patientinitiated plaque control techniques The plaque-host interaction can be altered by the effects of local factors, systemic factors, or both; medications; and malnutrition that can influence the severity and duration of the response.

II. Gingival diseases modified by systemic factors A. Associated with endocrine system 1. Puberty-associated gingivitis 2. Menstrual cycle–associated gingivitis 3. Pregnancy associated a. Gingivitis b. Pyogenic granuloma 4. Diabetes mellitus–associated gingivitis B. Associated with blood dyscrasias Leukemia-associated gingivitis This appears to be caused by the effects of the systemic conditions on the cellular and immunologic functions of the host. The prevalence and severity of gingival inflammation may increase even in the presence of little plaque.

The development and severity of gingival enlargement in response to medications is patient specific and may be influenced by uncontrolled plaque accumulation. The increased use of oral contraceptives by premenopausal women has been associated with a higher incidence of gingival inflammation and development of gingival enlargement that may be reversed by discontinuation of the oral contraceptive.
