Researchers Build a Smart Dental Implant that Resists Bacterial Growth

Researchers at the University of Pennsylvania have developed a smart dental implant. The implant will resist bacterial growth and generate electricity from its piezoelectric qualities. The electricity could power a light for phototherapy that will protect periodontal tissue from inflammation and disease. The Smart Dental Implant Millions of Americans have dental implants, which replace missing teeth due to decay, injury, or...

Study Examines the Link Between Mental Health and Oral Health

Is the phrase mind over matter true? A group of scientists has decided to test this theory by evaluating whether a person's sense of coherence and other psychological factors can have a noticeable impact on their oral health-related quality of life after receiving periodontal treatment. Their study, "Do psychological factors predict changes in oral health-related quality of life and...

Bactericidal Effects of Ultraviolet-C Light on Streptococcus mutans

Healthy teeth and gingiva impact our overall health and well-being. In a new study, researchers explored the use of ultraviolet-C (UV-C) light in fighting Streptococcus mutans, a bacterium associated with tooth decay. Clinical Uses for Ultraviolet-C Light The sun emits UV-A, UV-B, and UV-C irradiation. Ultraviolet light intensity is measured in milliwatts per square centimeter per second (mW/cm² * seconds) and exists in...

Troubled Relationship Between Periodontitis and COVID-19 May Further Exacerbate Disease Severity

International Study Looks at Whether People Can Inherit Periodontal Disease

Can someone's oral health be predetermined by their family's genetics? A Swedish study published in the Journal of Clinical Periodontology examined just that. The study was titled "Using National Register Data to Estimate the Heritability of Periodontitis."

Study Evaluates Changes in Dental Fluorosis Over Time

Fluoride is commonly found in nature, like in rocks, as well as in fluoridated water, dietary supplements, mouthwash, and toothpaste. It desirably protects against tooth decay, but too much exposure during childhood may lead to a condition called dental fluorosis. In milder cases, it causes light white lines or spots on the teeth, but it may lead to physical damage...
