Penetration of restorative resins into acid-etched human enamel

Abstract

In this investigation, the penetration of different resins into the etched enamel surface and the effect of their viscosity on the penetration of these materials were studied. Freshly extracted teeth were pumiced, rinsed, and dried. The enamel surface was etched by using a solution containing 50% phosphoric acid for one minute; in one group the teeth were etched for two minutes. A layer of enamel surface of another group of teeth was removed before etching; these teeth were etched for one minute. Three different resins--Nuva-Seal, Concise Enamel Bind, and Restodent--were applied to the acid-etched enamel surface for one minute. The Concise composite resin also was applied to the enamel surface of a group of teeth etched for the same period of time. Observations with SEM and polarized light microscopy showed penetration of all the materials into the etched enamel surface to be 5 mum to 10 mum, with a mean of 7 mum. There was no difference in the penetration of these materials despite their different viscosities. The removal of a layer from the enamel surface was not effective in the penetration of the materials.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
