Amelogenesis imperfect: Diagnosis and Management
Aetiology and pathology : Genetic in origin with a wide variety of Presentations.
Diagnosis: There are three main types:
- Hypocalcified. Although the enamel matrix is normal there has been inadequate calcification. The enamel is often opaque and may exhibit a wide variety of discolorations. It is soft and easily lost.
- Hypoplastic. Although the calcification is normal the enamel matrix is defective. The enamel therefore is hard and shiny but malformed. It may be prone to staining.
- Hypomaturation is described as giving a snowcapped appearance, where the underlying enamel has not matured fully but may have a thin layer of mature enamel overlying it.
Differentation should be made from other causes of tooth discoloration.
Management :The management of such cases can be part of a complex restorative treatment plan depending upon the severity of the condition. Restorative intervention may be required to protect the underlying tooth structure because of the poor enamel quality. Treatment may be needed for purely aesthetic reasons.
