Effect of trace elements on dissolution of hydroxyapatite by cariogenic streptococci

Journal of Dental Research
R J Herbison, S L Handelman


The effect of low levels of strontium, boron, lithium, molybdenum, and fluorine, alone and in combination, on hydroxyapatite solubility, bacterial growth, and acid production in five antigenic types of Streptococcus mutans was investigated. Pour plates containing synthetic hydroxyapatite were used to compare dissolution of hydroxyapatite. The colonies of the five antigenic types of S mutans produced zones of dissolution that were measured. Acid production and growth were studied in broth culture media. The results show that low levels of strontium and fluorine can significantly reduce demineralization of synthetic hydroxyapatite by S mutans in vitro.

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.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

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.
