Structural Porosity and Low Mineral Density in Enamel Rods Drive Molar Incisor Hypomineralisation

Advanced Functional Materials, EarlyView.
This study uses advanced imaging modalities on multiple length scales to show that molar‐incisor hypomineralization does not present as a locally homogeneous pathology. Instead, microstructural defects, characterized through non‐mineralized, protein‐rich sheaths and an altered mineral structure in between prism rods, resulting in local differences in ...

Volume of sealer in the apical region of teeth filled by different techniques: a micro-CT analysis

Brazilian Oral Research, 2016
The volume of sealer in the apical 1 mm of teeth filled using different techniques was evaluated by micro-commuted tomography (micro-CT). Sixty-four maxillary central incisors were prepared using NiTi rotary instruments.

An integrative description of a population of Mesobiotus radiatus (Pilato, Binda & Catanzaro, 1991) from Kenya [PDF]

, 2018
In a moss sample collected from Mount Kulal in Kenya, a new population of Mesobiotus radiatus was found. Given that the original description of M. radiatus was based solely on the morphology observed by light microscopy and measurements based mostly on a
