Fluorosis
|
Permanent hypomaturation enamel with increased surface porosity.
-Alteration in maturation phase of enamel formation. -Flouride levels >1ppm. Affects teeth developing during increased flouride intake. -Caries resistance |

|
-Max Central incisors and permanent 1st molars.
-Cause: Treponema pallidum infection in utero; organism disrupts enamel formation. |
