Study Notes
Enamel Defects
- Enamel defects can be caused by genetic and environmental factors.
- Abnormalities in enamel can be categorized into hypoplasia, hypomineralization, and hypomaturation.
- Hypoplasia is a reduction in enamel quantity, resulting in pits, grooves, or thin enamel.
- Hypomineralization is reduced mineralization, leading to soft enamel.
- Hypomaturation is characterized by altered translucency of enamel, often appearing opaque and discolored.
- Enamel defects caused by hypoplasia are thought to occur during matrix formation.
- Enamel defects caused by hypomineralization and hypomaturation arise from changes affecting enamel mineralization.
Dentin Defects
- Inherited dentin defects can affect only dentin or involve both dentin and bone.
- Two major types of dentin defects are dentinogenesis imperfecta and dentin dysplasia.
- Dentinogenesis imperfecta is the most common type of dentin defect.
- Dentinogenesis imperfecta Type I is associated with osteogenesis imperfecta, a genetic condition affecting bone.
- Dentinogenesis imperfecta Type II is a mild form of dentin dysplasia and is often associated with a mutation in the DSPP gene.
- Dentin dysplasia Type II is characterized by a mild form of dentinogenesis imperfecta.
- Dentin defects can be diagnosed early by screening family history and known associated medical conditions.
Rickets
- Â Rickets, a disease affecting bone development, can also affect dental health.
- Dental complications associated with dental rickets include enamel hypoplasia, delayed eruption, and tooth discoloration.
