Dean's Index
H.T. Dean's fluorosis index was first published in 1934. The index underwent two changes, appearing in its final form in 1942. This form became the most universally accepted classification system for dental fluorosis. An individual's fluorosis score is based on the most severe form of fluorosis found on two or more teeth.
| Classification | Criteria – description of enamel |
|---|---|
| Normal | Smooth, glossy, pale creamy-white translucent surface |
| Questionable | A few white flecks or white spots |
| Very Mild | Small opaque, paper white areas covering less than 25% of the tooth surface |
| Mild | Opaque white areas covering less than 50% of the tooth surface |
| Moderate | All tooth surfaces affected; marked wear on biting surfaces; brown stain may be present |
| Severe | All tooth surfaces affected; discrete or confluent pitting; brown stain present |
