Enamel developmental defects: environmental factors and clinical management

Abstract

Enamel formation is a complex physiological process that depends on the coordinated regulation of multiple mechanisms. This process is quite sensitive to various local and systemic interference factors. Therefore, during the long period from the embryonic stage to adolescence or even adulthood, various interference factors may lead to enamel developmental defects. Among them, early life is the most sensitive stage to environmental factors exposure, while it is also the critical period of enamel development of deciduous and permanent teeth. Environmental factors exposure during this period often leads to varying degrees of enamel development defects. In this review, we generalize the research progress of environmental factors affecting enamel developmental defects, summarize the potential mechanisms of environmental factors leading to enamel developmental defects, and conclude the clinical management strategies based on tertiary prevention. This work hopes to provide a theoretical basis for preventing abnormal teeth development from the critical time window of early life, propose eugenics health consultation and promote children 's oral health management.
