Nrf2 Signaling and Cytoprotection in Human Epithelial Airway Cells Exposed to HEMA -

Methacrylates are common constituents of resin-based biomaterials. These materials cure by polymerization of methacrylate monomers, but incomplete polymerization causes leakage and patient exposure to the electrophile monomers.

Lysherding – så enkelt og så vanskelig. -

For kort herdetid kan føre til mangelfull herding (polymerisasjon) av komposittmaterialer. For lang herdetid kan øke risiko for varmeskade på oralt bløtvev og pulpa. Herdelampens lysstyrke (irradians) reduseres når avstanden øker mellom lysutgangen og materialflaten.
For å opprettholde lysdosen som kreves for tilstrekkelig herding, må herdetiden økes. Kortere lysherdingstider enn omtrent 10 sekunder kan føre til utilstrekkelig herding av materialet.

Side effects of chemical compounds used in dental clinics -

The work at a dental clinic implies getting in contact with different chemical substances, which may cause temporary or permanent injury to the staff, primarily allergic reactions, but also local irritation, carcinogenic or toxic effects. Dentists and dental assistants belong to the professional groups most frequently experiencing work-related eczema.

Redefining the Phenotype of Dental Caries -

To our knowledge, this is the first study to separate patients into more discrete groups based on dental caries experience defined from longitudinal data and the first to study acute increases in DMFT score between two time points. Our hope with doing so is to provide more power in our predictions of genetic influences of dental caries and perhaps lead to better ways of studying the disease based on more specific categorizations of phenotypes.

A retrospective clinical study on the longevity of posterior Class II cast gold inlays/onlays. -

All dental restorations have a limited lifespan and will eventually need to be repaired or replaced. It is important to have in mind that the longevity of gold restorations have not been shown to be superior to that of resin composite, which should still be the first material of choice. However, gold inlays could be considered when the right indications are present.

Taste and smell perception in aging (Aldring, smak og lukt) -

Taste and smell are senses reacting upon solutes from food and breathing air conveyed by the cranial nerves. Normal aging includes cellulary and extracellulary biochemical mechanisms detrimental to neurons in the central nervous system, including those processing taste and smell signals. Aging also means reduction of the number of taste buds in the oral cavity and of the number of odor receptors in the nasal mucosa.
