Comparison of surface treatment protocols for a 3D‐printable resin for definitive crowns: Effects on surface roughness and bonding performance

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to compare the effects of surface treatment protocols on the surface roughness and shear bond strength (SBS) of a three‐dimensional (3D)‐printable resin for definitive crowns. Materials and Methods A 3D‐printable resin for definitive crowns (Saremco Print Crowntec) was used to produce 168 specimens (10 × 10 × 2 mm3 ...

The Unexpected Discovery of Paleocene? Coals in Outcrops Thought to Be Cambrian, Al Huqf, Oman

open access: yesJournal of Petroleum Geology, EarlyView.
ABSTRACT Two brown organic deposits were encountered whilst investigating kaolinitic claystones thought to occur at the base of a Cambrian formation at outcrop. The age of these organic deposits is probably Paleocene from palynology. Organic petrography shows that they are subbituminous coals with some oil source potential.

Holdfast adhesion in the kelp Alaria marginata: Cell wall polysaccharides and phenolics

open access: yesJournal of Phycology, EarlyView.
Abstract Adhesion is a critical process in the survival of seaweeds, especially in wave‐swept environments. Kelp (Laminariales) sporophytes secrete adhesives from specialized rhizoid cells to anchor themselves to the substrate and withstand immense forces applied by waves.

The oral microbiota and periodontal health in orthodontic patients

open access: yesPeriodontology 2000, EarlyView.
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.
