During the maturation stage, fluoride is released from the calcium and travels to the tooth surface, which can then enter the tooth during remineralization.

Study Notes
Dental Fluorosis
- Changes in the enamel which are associated with excess ingestion of fluoride.
- It can vary from white opacities, lines or flecks to more severe brown-yellow mottling of the enamel.
- The precise effect depends on the dose of fluoride (from all sources), duration for which it was taken, & the age of the patient at the time of ingestion.
- If excess fluoride is present it is thought to inhibit normal ameloblast activity during the matrix formation & maturation phase.
- Due to the hypolastic enamel formation becomes more porous & hence more hypomineralised.
- Enamel defects can result from other causes, not just fluorosis e.g. trauma, disease, drugs & genetics.
Aetiology agents
- The ingestion of the following can cause fluorosis:
- Dietary fluoride Supplements
- Drinking water
- Toothpaste
- Topical application
- Critical time is from 0-8 years as the teeth develop.
- Due to the staggered nature of tooth development, not all teeth will always be affected depending on the timing of the fluoride exposure.
