Study links dental flossing to higher levels of toxic chemicals in body

NEWTON, Mass., U.S.: Per- and polyfluoroalkyl substances (PFASs) are an important group of chemicals with wide applications, including dental floss, because of their ability to resist both water and lipids. A recent study, conducted by the Silent Spring Institute, has found that flossing with a certain brand contributes to elevated levels of toxic PFAS chemicals, which have been linked to various health problems, in the body.

The researchers measured 11 PFAS chemicals in blood samples taken from 178 middle-aged women enrolled in the Public Health Institute’s Child Health and Development Studies, a multigenerational study of the impact of environmental chemicals and other factors on disease. To understand how the participants’ behavior influenced their exposure to PFAS, the researchers then compared the blood measurements with results from interviews in which they asked the women about nine behaviors that could lead to higher exposures. The study found that women who flossed with a major brand tended to have higher levels of a type of PFAS called perfluorohexanesulfonic acid in their body compared with those who did not. To further understand the connection, the researchers tested 18 dental flosses for the presence of fluorine, which is a marker of PFAS. All three products of the major brand tested positive for fluorine. In addition, one store brand floss describing itself as a “single-strand Teflon fiber” tested positive for fluorine. The reason scientists are concerned about widespread exposure to PFAS in the population is that the chemicals have been linked to negative health effects, including kidney and testicular cancer, thyroid disease, high cholesterol, low birth weight, decreased fertility and effects on the immune system. “This is the first study to show that using dental floss containing PFAS is associated with a higher body burden of these toxic chemicals,” said lead author Katie Boronow, a staff scientist at the institute. “The good news is, based on our findings, consumers can choose flosses that don’t contain PFAS.” The study, titled “Serum concentrations of PFASs and exposure-related behaviors in African American and non-Hispanic white women,” was published online in the Journal of Exposure Science and Environmental Epidemiology on Jan. 8, 2019.

Study indicates potential of berry extract to fight off dental bacteria

BRISBANE, Australia: A recent study has suggested that concentrated extracts of polyphenol-rich fruits such as cranberries and blueberries could prove beneficial for combating certain bacteria in dental biofilm. The findings of the research, conducted at the University of Queensland in Brisbane and the University of Bristol in the UK, indicate the potential for cranberry phenols to modulate the pathogenicity of dental plaque.

The objective of the study was to continue testing natural components from fruit as bacteria inhibitors, and to further the research of their effects on oral health. The researchers tested high-quality extracts, prepared as bioactive molecules from cranberries, blueberries and strawberries, as well as a combination of the three berry extracts called Orophenol, on 24-hour-old Streptococcus mutans biofilms and compared them to the effects of a vehicle control. The study found that higher concentrations of cranberry extract significantly reduced the bacteria’s metabolic activity and acid production and bacterial/exopolysaccharide biovolumes, as well as resulted in a less compact architectural structure than that of the control-treated biofilms. Orophenol also had a significant impact, but slightly lower than that of cranberries. Only the highest concentration level of blueberry extract significantly reduced metabolic activity and acidogenicity, but did not significantly affect the biovolume or biofilm architecture. The extract from strawberries had no significant impact on any bacterial activity. No extract killed the bacteria. Continued research goes into fruit extracts for oral health care and bacteria management. The study, titled “Inhibitory effects of fruit berry extracts on Streptococcus mutans biofilms”, was published online in the European Journal of Oral Sciences on 28 December 2018 ahead of inclusion in an issue.

Interview: “Planmeca’s Compact i5 is a future-proof, ecological and safe investment”

As one of the world’s largest dental equipment manufacturers, Finnish company Planmeca is committed to providing products that can be enjoyed by dental practitioners and patients alike. Nowhere is this more evident than in the company’s new dental unit, the Compact i5—created for easy upgrade with new features as they are developed. Dental Tribune International spoke with Kaisu Ilomäki, product manager for Planmeca’s dental care units, about what exactly makes the Compact i5 an ideal solution for dental practices.

Firstly, how is the Compact i5 designed to benefit patients? There are a number of ways in which it benefits patients. The automatic leg rest ensures that sitting down is as easy as sitting down on a normal chair, and further creates a feeling of equality between the patient and dentist during the initial communication. This is very important, as loss of control can often be a cause of stress for patients. It is also possible to choose custom-moulded Ultra Relax upholstery with viscoelastic filling that will provide maximum support for the patient, which is particularly appreciated in long treatment sessions. The memory foam adapts well to different body anatomies, thereby allowing the patient to relax. And how is it designed to benefit the dental team? The Compact i5 has a floating chair and small cuspidor base, enabling a lot of space for the legs and good positioning for the foot control. The vast delivery arm movement, together with the narrow upper part of the back-rest, also allows for easy access to treatment, and the balanced instrument arms enable comfortable and effortless instrument use. Planmeca Compact i5 adapts to different working habits, offering a wide variety of options. In addition, owing to the integrated and automated infection control systems, the maintenance functions are easily and quickly performed, contributing to a safe treatment environment for both patient and dental team. The Compact i5 has been designed with future proofing in mind. Could you briefly explain how it achieves this, and why this is a point of emphasis for Planmeca? The Compact i5 is guaranteed to have a long life cycle, so it is important that upgrades to this unit are made possible. The modular design and software-controlled system make it possible for dental practitioners to first buy a basic set-up and then upgrade the unit with new features later on. Upgrading the existing unit with our Planmeca PlanID system, for example, will grant an unlimited number of user profiles, particularly useful in large group practices. It is also possible to add a newly introduced instrument, however, or to enable additional functionalities through a software upgrade. We use primarily aluminium parts with a timeless design as well for the Compact i5, which helps to ensure that the dental unit will be stable and attractive in the future. Overall, Planmeca’s Compact i5 is a future-proof, ecological and safe investment. Will the Compact i5 be on display at the 2019 International Dental Show? Of course! We invite all attendees to visit us at Stand G010/H011 in Hall 11.1, where they can experience not just the Compact i5 in action, but also our range of solutions for digital dentistry. Thank you very much for the interview.
