Enamel development may be affected by intrinsic or extrinsic factors. These factors can result in defects of enamel structure (hypoplasia) or composition (hypomineralization) (Table 1). Clinical presentation often involves a combination of hypoplasia and hypomineralization which may be present in varying degrees of severity across the dentition.
Diagnosis of these defects is often challenging and requires a thorough history, clinical and radiographic assessment. The differential diagnoses of enamel defects are described in Table 2.
Cases 1 and 2 show the dentition of identical twins with enamel defects (Figures 1 and 3). No aetiological factors were identified in the history taken from the patients or their mother.
The white mottling, brown staining and heavily broken down mandibular molars represent an array of enamel defects including molar-incisor hypomineralization (MIH), chronological hypoplasia and amelogenesis imperfecta (Table 2). Specifically, there are hypomineralized patches, pitting and severely broken down first molars.
