Enamel maturation: a brief background with implications for some enamel dysplasias

Area of Science:

• Biomineralization
• Tooth Development
• Dental Enamel

Background:

• Enamel maturation follows matrix secretion and involves cellular changes and matrix degradation.
• Crystal growth is central, with mineral ions replacing tissue fluid to achieve full density.
• Post-eruptive maturation can occur if full maturation is not achieved by eruption.

Purpose of the Study:

• To detail the processes occurring during the enamel maturation stage.
• To elucidate the roles of ion transport and potential vulnerabilities during maturation.
• To understand factors affecting the final quality of dental enamel.

Main Methods:

• Review of the biological processes involved in enamel maturation.
• Analysis of ion transport mechanisms (calcium, phosphate, fluoride, magnesium).
• Identification of factors compromising enamel maturation.

Main Results:

• Maturation involves cell transition, matrix removal, and crystal growth.
• Ion transport (Ca, P, F, Mg) is crucial but not fully understood and can be bidirectional.
• Enamel maturation is prolonged and vulnerable to exogenous molecules and excessive fluoride.

Conclusions:

• Enamel maturation is a complex, multi-step process critical for tooth integrity.
• The vulnerability of this stage to external factors can result in incompletely mature enamel.
• Further research into ion transport mechanisms and protective strategies is warranted.
