Decisions on diagnosis and management of approximal caries by final-year dental students

Dento Maxillo Facial Radiology
G Maupomé, A Sheiham

Abstract

To investigate the decision-making processes for dental caries from bitewing radiographs of final-year dental students in Mexico City. Five sets of radiographs were converted to slides and projected on a screen under standardized conditions. 143 students were asked to determine separately the presence of all proximal caries, of proximal lesions to be restored in the present course of treatment, and of unreadable surfaces due to technical deficiencies. A gold standard was obtained from two expert clinicians who examined the radiographs under similar conditions. Misdiagnoses were common. Overdiagnoses became evident at the treatment planning stage where many surfaces were incorrectly planned for restoration. Subjective appraisals of presence of lesions, unreadable surfaces, and surfaces planned for restoration showed substantial variation. Students' overall assessment of lesions detected did not differ between restored and unrestored surfaces. However, when compared with the gold standard, their decision-making was found to be better on surfaces which had not been restored previously as opposed to those already restored, both in terms of identification of lesions and in terms of treatment planned for deeper lesions.

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.
