Dentists increasingly use articaine 

by

An interesting article titled “Survey investigation of articaine use in the United States,” written by Robert D. Bowers and et. al. appears in the the Journal of the American Dental Association (published Oct. 2023). The article conducted a study to expand the knowledge of local anesthesia practices of dentists in the U.S. with a specific focus on influencing factors regarding articaine. The U.S. Food and Drug Administration approved the use of articaine in 2000 and dental use of articaine has grown over the years. In 2017, it was estimated that estimate about 40% of the total U.S. dental local anesthetic market was for articaine. However, articaine has a 4% concentration which has led some to question its safety. Past studies have shown that higher concentrated local anesthetics like articaine can lead to increased risk of dental paresthesia. To study the use … Read more

Barriers in Teledentistry Exist

by

An interesting article titled “Teledentistry Adoption and Use During the COVID-19 Pandemic” written by M, Fernando T, Surdu S, and Romero A. appears in the Oral Health Workforce Research Center, Center for Health Workforce Studies (July 2023). The article sough to explore how the adoption of teledentistry has changed in recent years and what barriers still exist with its use. Teledentistry has been discussed before on this site such as at the post Delivering Dentistry and Counseling to Patients using Telemedicine. Teledentistry is defined as using electronic information including interactive audio, video, and data communications to provide and support dental care whereby the care occurs virtually from where the oral health professional is licensed. Teledentistry provides an efficient way for dental professionals to consult, diagnose, follow up, and offer health education to patients and helps to reduce the number of in-person visits.  The … Read more

The life events of people can be told by teeth

by

An interesting article titled “Parturitions, menopause and other physiological stressors are recorded in dental cementum microstructure” appears in Scientific Reports written by Paola Cerrito and et al. (vol. 10, pp. 5381, 2020). The article discusess how the life events that people have experienced can be told by their teeth. In the article the researchers conducted a study of cementum microstructure of 47 human teeth, from 15 individuals with a known life history. The teeth were processed at the Hard Tissue Research Unit of the NYU College of Dentistry. The life history events of the patiens like age, illnesses, and relocations were known and had been reported from the patients relatives. The researchers used a series of imaging techniques that illuminated cementum rings, and then linked the rings to different life stages. Doing so allowed them to reveal connections between tooth … Read more

Oral Bacteria May Lead to More Heart Disease

by

An interesting article titled “Associations of genetic and infectious risk factors with coronary heart disease” appears in eLife published on February 14, 2023, written by Flavia Hodel and et. al. The article discusses how common bacteria that has been linked with periodontal disease, oral cancers, and bad breath increase the chance of developing heart disease. In the past it has been discussed on this site how Brushing Teeth Twice a Day to Help Prevent Heart Disease and Bacterium goes from the mouth to the heart to cause disease. In the current article, the authors mention how cardiovascular diseases (CVDs) are the leading cause of mortality in the world and it is believed 17.9 million people die from CVD each year. The authors performed multiplex serological testing for persistent or frequently recurring infections and genome-wide analysis in a prospective population study. … Read more

Enamel Composition May Help Predict Tooth Health

by

An interesting article titled “Mesoscale structural gradients in human tooth enamel” appears in the Proceedings of the National Academy of Sciences written by Robert Free and et. al. (vol. 119, no. 52, pp. e2211285119, December 19, 2022). The article explores the hierarchical architecture of human enamel which is integral to the function of human teeth. In the article, discussion is made of how tooth decay has lead to many dental visits due to cavities. There is not much known about how or why many people experience tooth enamel decay or congenital conditions. In the article, the authors used synchrotron X-ray diffraction at submicrometer resolution technology, to observe tiny differences on the order of picometers in the crystallographic parameters of enamel crystallites, which they linked to the presence of ions such as magnesium and sodium or carbonate. Features of enamel at length scales smaller … Read more
