Abstract

To describe the clinical caries status and the radiographic progression of occlusal caries lesions in permanent first and second molars among primary schoolchildren in Dar es Salaam over a 3-year period. Clinical and radiographic diagnosis of caries in first and second permanent molars in 223 children aged 8-16 years were carried out annually from 1994 to 1997. The drop-out rates from the baseline in 1994 to the follow-up examinations in 1995, 1996 and 1997 were 16.6%, 22.0% and 35.4%, respectively. Twenty-one percent of the dropouts were picked up during the study. Less that 5% of all occlusal surfaces that were sound at the beginning of the study developed new clinical caries lesions over the 3-year study period. The highest rate of new lesions was found in second molars. The mandibular second molars were most frequently affected by new caries lesions followed by the mandibular first molars. Progression of lesions was generally slow. After 1, 2 and 3 years, 30.0%, 47.9% and 52.8% of lesions in occlusal surfaces of first molars had progressed, compared to 47.9%, 71.3% and 100.0% of lesions in second molars. Dental caries prevalence was low. New occlusal lesions were more likely to appear in mandibular second molars. Carious le...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.
