Dentists Find Additional Bacteria Species Involved with Tooth Decay

by

An interesting article titled “Selenomonas sputigena acts as a pathobiont mediating spatial structure and biofilm virulence in early childhood caries,” written by Hunyong Cho and et. al. appears in Nature Communications (vol. 14, no. 1, 2023). The article seeks to study if other bacteria besides Streptococcus mutans are involved with tooth decay and cavities in children, also known as dental caries. Prior to the study it was believed that S. mutans and other acid-making bacteria are adequately removed by teeth-brushing and oral care, and this creates a protective biofilm, or plaque, on teeth. If the plaque is left in place for too long, bacteria consumes sugars from food and drinks and coverts them to acidsm which erode the enamel of affected teeth, in time creating cavities. The article investigated the role of Selenomonas sputigena (S. sputigena) in early cavities in children. S. … Read more

What to Expect for Your First Dental Filling

by

When you go for your first dental filling, whether it’s just one of the first of many, there are a few things to expect. Whether you have a cavity needing a filling or your tooth has been severely worn away by grinding at night, you can trust that the procedure is less traumatic than you’ve been previously led to believe. What Is a Filling, Anyway? The ultimate goal of dentistry is to make your smile as beautiful and long-lasting as possible. To maintain that beauty, your dentist may have to place a dental filling, also known as a “dental restoration,” in your tooth. Dentists can use a variety of dental fillings for the many different kinds of dental cavities. Dental fillings are used in cases where cavities are present in the teeth. A cavity is caused when a sugar-craving bacteria … Read more

Dental Material that Kills Bacteria and Resists Biofilm Growth

by

Researchers from the University of Pennsylvania have developed a dental material tethered with an antimicrobial compound that can kill bacteria and resist biofilm growth. The material is also effective with minimal toxicity to the surrounding tissue, as it contains a low dose of the antimicrobial agent that kills only the bacteria that crosses it’s path. The researchers were motivated to develop a new dental material because the current composite materials to perform restorative procedures, such as filling cavities, are vulnerable to the growth of plaque, the biofilm that leads to tooth decay. The researchers had two goals in mind when developing the dental biomaterial: 1) kill pathogenic microbes effectively, and 2) withstand severe mechanical stress. The newly developed material is composed of a resin embedded with the antibacterial agent imidazolium. Unlike some traditional biomaterials that slowly release a drug, this material is non-leachable … Read more

Is Pediatric Dental Death Avoidable?

by

An interesting article titled “Pediatric Dental Anesthesia: An Avoidable Tragedy,” written by Lee et al. appears in the December 2017 edition of Pediatrics (vol. 140, no. 6). In the article the authors present a case of a dental death after anesthesia for early childhood caries and have experts provide commentary. Pediatric dental deaths have been reported in the news over the years with all too much frequency. See the dental deaths page for numerous cases and the original source of the information regarding the case. In the article by Lee the authors say how young children with early childhood caries or cavities are often treated using moderate sedation or general anesthesia. It is estimated that up to 250,000 pediatric sedations for dental treatment occur in the U.S. each year. In these sedations the children are often given benzodiazepines, opioids, nitrous … Read more
