Less sleep may increase cavities risk

by

An interesting article titled “Association between sleep duration and dental caries in a nationally representative U.S. population” written by Abdullah Alawady and et. al. appears in BMC Oral Health (vol. 23, Article number 497, 2023). The article seeks to establish the relationship between sleep duration and dental caries (cavities). The authors used data from the 2017-2018 U.S. National Health and Nutrition Examination Survey to explore 5,205 patients age 16 and older who completed a dental exam and sleep questionnaire. They performed regression analyses to reveal a statistically significant negative relationship between caries and sleep duration. It was found that those who have an average sleep duration of seven or more hours per night were less likely to have caries compared to people who slept less than seven hours (95% confidence interval 0.33 to 0.82; p < 0.05). Specifically 88.9% (4630/5205) of the … Read more

High Birth Weight Linked to Early Childhood Tooth Decay

by

A recent study has revealed a significant association between high birth weight and the risk of early childhood tooth decay (ECC) (Wang, H., Zhang, H., Zeng, X. et al. Association between high birth weight and dental caries at 4–5 years of age: a birth-cohort study. BMC Oral Health 24, 896 2024). Researchers from the Shanghai Stomatological Hospital & School of Stomatology in China analyzed data from 491 children aged 4 to 5 years old and found that children born weighing 4,000 grams (8.8 pounds) or more were more likely to develop ECC compared to those with normal birth weight. ECC is when there is a presence of one or more decayed, missing, and filled tooth surfaces in any primary tooth in a child less than 71 months old. The study was designed as a retrospective longitudinal register-based cohort study that included pregnant women in … Read more

Stannous Flouride Combination Can Eliminate Dental Cavities

by

An interesting article titled “Iron oxide nanozymes stabilize stannous fluoride for targeted biofilm killing and synergistic oral disease prevention” written by Yue Huang and et. al. appears in Nature Communications, vol. 14, No. 6087, 2023. The article discusses a potent therapeutic synergism using approved agents while providing facile stannous fluoride stabilization, to help prevent oral disease and dental caries (cavities). The authors describes a new method for using iron oxide nanozymes to stabilize stannous fluoride and improve the ability to kill biofilms. Biofilms are communities of bacteria that can form on teeth and other surfaces in the mouth. They are difficult to remove and can lead to tooth decay and other oral diseases. Stannous fluoride is an effective antimicrobial agent, but it is unstable and can be difficult to deliver to the site of infection. Ferumoxytol, an iron replacement, stabilizes stannous fluoride … Read more

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
