The Journal of Clinical Pediatric Dentistry
Sherry Shiqian GaoChun Hung Chu

Abstract

Early childhood caries (ECC) was prevalent in Hong Kong. Children with ECC risk should be identified early for prevention. This study aimed to identify common risk factors of ECC in Hong Kong 3-year-old children. Sample size calculation showed at least 6,321 of 3-year-old children should be invited in this study. A consent form and a questionnaire enquiring the children's oral health behaviours and social-economic background were distributed to their parents. Children with parental consent were examined by a trained dentist. Caries status was recorded in dmft index. Chi-square test and logistic regression analysis were performed to identify the risk factors of ECC. A total of 5,167 children from the 6,331 children invited were examined. Among them, 1,130 children (22%) had ECC (dmft>0). Logistic regression analysis found age of starting tooth brushing, snack-intake frequency, dental visit experience, birthplace, family monthly income, primary caretaker, and mother's education level were factors associated with ECC of the children. Children who started tooth brushing later, had higher snack-intake frequency, were not born in Hong Kong, and whose family monthly income was lower, mother's education level was lower, primary caretak...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.
