Enamel with a white or brown discoloration without hypoplasia.
Comment:
Enamel maturation is a process through which enamel matrix proteins are removed to allow full growth of the enamel hydroxyapatite crystals. Hypomature enamel can be caused by genetic or environmental factors. It may occur in both deciduous and permanent dentitions, although more often in the permanent dentition. Hypomature enamel may concern a single tooth, several teeth, or the complete dentition and may affect part or the complete surface of the tooth. The enamel is usually hard, colored but not translucid. It is a qualitative defect of enamel.
