Microscopic study of dental hard tissues in primary teeth with Dentinogenesis Imperfecta Type II: Correlation of 3D imaging using X-ray microtomography and polarising microscopy

Highlights • Teeth affected by dentinogenesis imperfect are investigated with polarised light microscopy and X-ray microtomography. • Structures and mineral distributions are studied in three dimensions. • Large tubules are seen corresponding to the original location of primary dentine. • A network...

Description
Summary:Highlights • Teeth affected by dentinogenesis imperfect are investigated with polarised light microscopy and X-ray microtomography. • Structures and mineral distributions are studied in three dimensions. • Large tubules are seen corresponding to the original location of primary dentine. • A network of vessels, or the remnants of vessels, is seen in the location of the original pulp chamber. • Even after apparent complete obliteration of the pulp chamber, this network of vessels may provide a pathway for bacterial infection.
