Abstract

Proximal contact loss due to caries may contribute to the appearance of marginal alveolar bone loss (ABL) in the deciduous dentition. Children referred for treatment to the School of Dentistry, University of Otago, usually have special problems related to caries or management, or both, and the aim of the study was to determine the prevalence of marginal ABL in children treated in this clinic, and to compare it with that found in a previous study in a random sample of New Zealand 5-year-olds. Posterior bite-wing radiographs of 187 children, aged 4 to 14 years, were selected for examination. A total of 1,523 sites, from the distal of the deciduous cuspids to the mesial of the deciduous second molar or the first permanent molar if present, were examined. ABL was recorded when there was complete absence of the lamina dura and the distance from the cemento-enamel junction to the crest of the alveolar bone was > 2 mm. ABL was found in 20.8 percent of the children; 31.9 percent of these sites were adjacent to extensive proximal caries; 83.3 percent were in the maxilla, and 95.8 percent were between deciduous teeth. The youngest age at which ABL was found was 5 years. Among the children with ABL, 48.7 percent had ABL in more than one s...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.
