Oral hygiene is a basic factor for oral health. Poor oral hygiene leads to dental plaque-collections, which in turn can cause gingivitis eventually leading to periodontal diseases. That is why many clinical studies have been carried out focusing on the role of oral hygiene in the prevention and control of oral diseases.
Dental plaque is defined as the soft adherent structured deposits, which forms on the tooth surface. It consists of a mixed bacterial flora, sometimes with desquamated epithelial cells and migrated polymorphonuclear leukocytes. It is not and should not be confused with food debris.
A number of plaque indices has been developed for assessing individual levels of plaque control and are also been used in several epidemiological studies. Some of the most well - known indices, which have been used in numerous studies, are listed below.
- Oral Hygiene Index (Greene and Vermilion, 1960)
- Simplified Oral Hygiene Index | OHI-S (Greene and Vermilion, 1964)
- Silness-Löe Index (Silness and Löe, 1964)
- Quigely Hein Index (modified) (Turesky, 1970)
- Plaque Control Record (O' Leary T, Drake R, Naylor, 1972)
