Research Shows Patients with Drug Addictions Labeled ‘Demanding” by Dental Professionals

In Norway, dental treatment is run by the Public Dental Service (PDS) and is free for children, adolescents, and young adults until age 19. Anyone who has a documented mental disorder, developmental disability, the geriatric population, and people who live in assisted living or utilize at-home nursing care receive free dental care. As an extension to this rule, in...

Research Examines Use of Concentrated Growth Factor During Tooth Transplant Surgery

Patients experiencing tooth loss may benefit from dentures or dental implants, but tooth transplants also show promising results. In a recent study, researchers used a substance extracted from the patient's own blood called concentrated growth factor, in addition to 3D-printed tooth replicas, to promote healing and recovery from tooth transplant surgery. Medical Applications of Concentrated Growth Factor A platelet-rich substance called concentrated growth...

Periodontist Sentenced to Six Weeks in Prison for College Admissions Scandal

A former associate professor of dentistry at the University of Southern California was sentenced to six weeks in prison on November 10th for his role in the Operation Varsity Blues scandal, where wealthy parents participated in a scheme to enroll children at top universities.

Study Looks at Oral Health Complications of Kidney Re-transplant Patients

Organ failure results from a variety of reasons, like genetic disorders, drug or alcohol abuse, or injury. In addition to treatments and medications, an organ transplant may increase the patient's quality of life, but sometimes an immune response causes the patient's body to reject the donor's organ. Immunosuppressive medications reduce this immune response, but with unfortunate side effects, like...

Research Shows Panoramic Radiographs’ Ability to Diagnose Bruxism via Bone Remodeling

Patients who experience bruxism, or teeth grinding and clenching, often suffer from jaw pain, tooth sensitivity, headaches, and other symptoms. A diagnosis usually starts with a patient's self-report data, but bruxism may go unnoticed for those who grind their teeth unconsciously. A recent study from Switzerland shows promising results in using panoramic radiographs to diagnose bruxism by looking for changes in...

VIDEO: Discussing Negative Comments from a Lobbyist about Hygienists

Emily Boge, CDA, RDH, MPA, and Kara Vavrosky, RDHEP, discuss the recent comments made by an Illinois Dental Society lobbyist saying this about dental hygienists: "I just don't feel anybody with a two-year associate's degree is medically qualified to correct your health. They're trained to clean teeth. They take a sharp little instrument and scrape your teeth. That's what...

The Federal Trade Commission (FTC) filed a lawsuit on October 28, 2021, against a dental manufacturer, Xlear, Inc., saying the company “falsely pitched its saline nasal sprays as an effective way to prevent and treat COVID-19.” The federal agency said Xlear violated the COVID-19 Consumer Protection Act with its claims about the nasal sprays. The legislation was enacted by Congress...

Tooth Loss May Be Linked to Dementia and Cognitive Impairment

A new study by New York University Rory Meyer College of Nursing researchers found that each tooth you lose increases your risk of dementia and cognitive impairment. In their findings, published in JAMDA: The Journal of Post-Acute and Long-term Care Medicine, the researchers report a decreased risk of cognitive decline in older adults using dentures. These findings suggest that you...

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...

Can a Patient’s Baseline Periodontal Stage and Grade Predict Tooth Loss?

Good oral health is essential for overall health and if you want to enjoy a higher quality of life. Harmful dental conditions such as periodontitis can have a serious impact on the body and systemic health. A recent scientific study examined whether the baseline stage and grade could predict future tooth loss due to periodontitis. The study, "The influence...

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

COVID-19 is being studied by researchers all over the world. Where did it come from? How can we stop it? While we cannot answer these questions definitively, researchers are still tackling the pandemic and its relationship with other serious health problems. For example, researchers have been studying the effects that COVID-19 may have on common diseases, such as periodontitis. The...

A study has found that a high-fat diet can have lasting implications on a person's oral health. The research findings were presented in the Journal of Clinical Periodontology under the title, "Untargeted and Targeted Gingival Metabolome in Rodents Reveal Metabolic Links Between High-Fat Diet-induced Obesity and Periodontitis." Information About High Fat Diets Your diet can have a lasting impact on your overall quality...

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."
