Abstract

To compare the diagnostic accuracy of a dental radiographic film (Ektaspeed Plus) with the Sens-A-Ray direct digital imaging system using a proximal caries model. To study the effects of a scattering medium and compare the interpretations of dentists with dental students. We used 20 extracted premolar and molar teeth with 10 sound and 15 naturally carious surfaces, and prepared artificial cavities in the remaining 15 surfaces. Seven dentists and seven senior dental students reported the presence of lesions using a five point confidence scale. We analysed our data by Receiver Operating Characteristic (ROC) analysis and by obtaining sensitivities and specificities. ROC areas showed no significant differences in the diagnostic accuracy achieved by dentists and dental students or by the addition of 20 mm of water as a scattering medium. A paler set of exposures produced significantly poorer diagnostic accuracy, but a darker set gave insignificant differences. Highly significant differences were found between the ROC areas for film and Sens-A-Ray and natural caries and artificial cavities, but the magnitudes of the differences were small. Sensitivities and specificities showed greater differences between methods and identified infer...Continue Reading

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.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

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.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
