Molar incisor hypomineralisation: current knowledge and practice

International Dental Journal, EarlyView., 2020
Background Molar incisor hypomineralisation (MIH) is a common developmental dental condition that presents in childhood. Areas of poorly formed enamel affect one or more first permanent molars and can cause opacities on the anterior teeth. MIH presents a variety of challenges for the dental team as well as functional and social impacts for affected ...

Nanometer Layer Coating to Lactose Particles for Optimization of Dexamethasone Pulmonary Delivery

Advanced Science, EarlyView.
Nanometer layer coating (NLC) was investigated and its mechanism illustrated by advanced characterization techniques. The effects and application for the inhalation of dexamethasone (DEX) were demonstrated through in vitro and in vivo evaluation. This approach increased DEX bioavailability and enabled the dose to be reduced to 1/30 of the intravenous ...
