Structural, mechanical and chemical evaluation of molar-incisor hypomineralization-affected enamel: A systematic review

Abstract

OBJECTIVES: To systematically assess and contrast reported differences in microstructure, mineral density, mechanical and chemical properties between molar-incisor-hypomineralization-affected (MIH) enamel and unaffected enamel. METHODS: Studies on extracted human teeth, clinically diagnosed with MIH, reporting on the microstructure, mechanical properties or the chemical composition and comparing them to unaffected enamel were reviewed. Electronic databases (PubMed, Embase and Google Scholar) were screened; hand searches and cross-referencing were also performed. RESULTS: Twenty-two studies were included. Fifteen studies on a total of 201 teeth investigated the structural properties, includin..
