An interesting article titled “Entamoeba gingivalis Causes Oral Inflammation and Tissue Destruction,” appears in the Journal of Dental Research written by X. Bao and et al. (vol. 99, no. 5, pp. 561–567, 2020). The article seeks to explore the protozoan Entamoeba gingivalis (E. gingivalis) in inflamed periodontal pockets. In the article, the authors sought to validate the frequency of the Entamoeba gingivalis by analyzing the gums of 158 people with periodontitis and healthy controls using polymerase chain reaction and microscopy tests. A total of 107 of the people in the study were healthy controls while 51 had periodontitis. For those healthy control patients, E. gingivalis was detected in oral cavities in 15% of these patients. For those with periodontitis, E. gingivalis was detected in 77% of inflamed periodontal sites and 22% of healthy sites. The authors state “In conjunction with abundant … Read more

Panoramic X-Ray Showing Tooth Inside Chin Lights up Internet

Grant Awarded to Help Improve How Primary Care Doctors Apply Fluoride Varnish on Kids Teeth

Could a Medication One Day Be Given Instead of Braces to Control Tooth Movement?

Recent research from Tokyo Medical and Dental University (TMDU) showed that osteocytes have a crucial role in orthodontic tooth movement as the major source of receptor activator of nuclear factor kappa-Β ligand (RANKL) which is a protein critical to bone remodeling. It is  known that the differentiation of osteoclasts is regulated by RANKL. However, the source of RANKL in the periodontal tissue during orthodontic tooth movement was not previously identified. Now thanks to the research team it is know that osteocytes mainly express RANKL and play a key role in the remodeling of  bone surrounding teeth during orthodontic tooth movement. To explore this issue, the researchers used an orthodontic tooth movement model in which open coil springs were inserted between teeth of mice to move first molars. They then injected a neutralizing antibody against RANKL intended to reduce tooth movement. The … Read more
