For years, medical research has found that fluoride in toothpaste helps to prevent tooth decay and protect against cavities. As a result, most toothpastes contain between 1,000 to 1,100 mg/L of sodium fluoride or monofluorophosphate. But a new study has found that fluoride-free toothpaste is just as effective at preventing cavities as fluoride-based toothpaste. So, does this mean the end of using toothpaste enhanced with fluoride?
The study’s key findings
Poznan University of Medical Sciences carried out a study involving 171 participants over a period of 18 months. The participants were split into two groups. One group used hydroxyapatite (fluoride-free) toothpaste and the other group used fluoridated toothpaste throughout the study. Six-monthly trips to a dental clinician were completed and a DIAGNOcam device and plaque-disclosing solution were used to check for signs of cavities and plaque. The end results revealed that almost 90% of people in both groups had no new cavities, which indicates that both hydroxyapatite toothpaste and fluoridated toothpaste keep cavities at bay.

Response: Dental caries is one of the most common and costly biofilm-dependent diseases that afflict children and adults worldwide. Particularly, Early Childhood Caries (ECC) is a hyper-virulent type of chronic tooth decay that most frequently afflicts underprivileged preschool children. The onset and progression of carious lesions in ECC are rapid and aggressive, causing rampant destruction of the smooth surfaces of teeth.
ECC is painful and often requires surgical procedure under general anesthesia, while current treatment modalities are inefficient and recurrence of ECC is common. Notably, interactions between a fungus, Candida albicans, and a bacterium, Streptococcus mutans, have been known to play important roles in the pathogenesis of dental caries.
Thus, we attempted to strategically develop a targeted measure to effectively prevent cross-kingdom interactions and subsequent biofilm development.

Response: Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are chemical groups that have had a wide variety of uses due to their ability to their ability to repel water and stains. They might be found in food packaging, water-repellant clothing and carpeting, paints, fire-fighting foam, and water, for example. Although many are no longer manufactured in the United States, PFAS persist in the environment as they do not readily break down. Adverse health effects have been speculated especially for low birthweight babies, immunological effects, certain cancers and thyroid hormone disruption.1 With these considerations, we hypothesized that there may be an association of PFAS with tooth development and subsequent dental caries (cavities).
