Many Retainers Contain Some Form of Bacteria

If retainers aren’t cleaned fully, microbes tend to build up on them, according to the UCL Eastman Dental Institute.

A study was recently conducted analyzing the types of microbes that live on retainers. At least 50 percent of retainers contain pathogenic microbes, according to the study.

This study appears in the journal Letters in Applied Microbiology.

Based on the findings in the study, new cleaning products are necessary to improve the cleanliness on retainers.

Periodontitis Could Lead to Diabetes

Chronic periodontitis, which affects about half of all Americans over 55, is two to four times more likely to be developed by people with diabetes.

That conclusion was made by the Stony Brook School of Dental Medicine, which conducted a study on whether or not treatment of chronic periodontitis will help treat diabetes.

The American Diabetes Association states that Type 2 diabetes is the fifth leading cause of death in the United States.

Researcher Claims Postmenopausal Women Should Increase Dental Visits

Postmenopausal women likely aren’t visiting the dentist enough.

According to a study by the Case Western Reserve University School of Dental Medicine and the Cleveland Clinic, two dental checkups each year aren’t enough. The conclusion was made after studying women who are on bone-strengthening bisphosphonate therapies for osteoporosis.

Leena Palomo, the assistant professor of periodontics from the Case Western Reserve University School of Dental Medicine, and Maria Clarinda Beunocamino-Francisco from Center for Specialized Women’s Health at the clinic wanted to analyze the impact of bisphosphonate therapies on the jawbone. However, they ended up determining that postmenopausal women should visit the dentist more often.

Infant Formulas Have Fluoride; Avoid Mixing with Fluoridated Water

All infant formulas, either concentrated or ready-to-feed, already contain some fluoride and, when routinely mixed with fluoridated water, increase the risk of dental fluorosis (discolored teeth), according to Dr. Howard Koh, Assistant Secretary for Health, U.S. Department
of Health and Human Services (HHS) in a video commentary published on medscape.com. (1)

Fluoride, added to water supplies ostensibly to reduce tooth decay, is also in food, beverages, dental products, medicines, and anesthesia and inhaled from ocean mist and air pollution. As a result, more than 41% of adolescents are fluoride-overdosed and afflicted with dental fluorosis—more than 3% of it is moderate to severe (brown stains and pitting), according to the Centers for Disease Control.

Second-hand Smoke Could be Related to Cavities

A new study indicates that second-hand smoke may have an effect on cavities.

People who inhale second-hand smoke may be at a higher risk for cavities, according to the study, which was led by Dr. Taru Kinnunen, the director of the Tobacco Dependence Treatment and Research Program at the Harvard School of Dental Medicine.

Dr. Kinnunen mentioned this study when speaking at the University of Manitoba’s dental faculty annual research day. He said that second-hand smoke caused the risk of cavities to rise because smoke still entered the naval cavities and the mouth. As a result, the saliva was impacted.
