ENAMEL HYPOPLASIA RESTORATION
There are three basic goals to the treatment of enamel hypoplasia (actually enamel hypocalcificatin). The first is to remove the dentinal sensitivity produced when the enamel is lost from the tooth surface. The second is to improve esthetics (or looks) of the tooth. Finally, depending on the severity and location of the defect, additional strength may be desired to decrease wear and the possibility of fracture.
Decreasing the dentinal sensitivity can be accomplished in one of three ways. The simplest way is via fluoride treatment. This will not only decrease the dentinal sensitivity, but can also strengthen the tooth. Another option is to perform dental bonding of a
composite restoration over the lost area. This can be very effective in decreasing the dentinal sensitivity, and will also increase the esthetics if a shade that matches the tooth color is used. Finally, a full coverage
crown can be employed, however this is often reserved for large areas of loss.
Improved esthetics can be achieved either by the aforementioned composite restoration or depending on severity by a full coverage
crown. The composite restoration is good for small areas that will not undergo much masticatory trauma. There is a tendency for these restorations to be lost in high stress areas over time. If there are large areas, especially in occlusal surfaces, a full coverage crown can provide good to excellent esthetics
Increased strength can only be effectively achieved by a full coverage crown. This will require two anesthetics, but is the best for long term treatment of large areas of hypoplasia. In addition, this will decrease sensitivity and depending on the crown material chosen can provide excellent esthetics.
