Scientific study: A new method for determining the true fluoride effectiveness in toothpastes developed in Latvia
When brushing our teeth, we rely not only on toothpaste to freshen our breath but also to protect our teeth. For this to happen, the presence of fluoride – a mineral that strengthens tooth enamel and helps prevent cavities is essential. Therefore, to more accurately assess the effectiveness of toothpastes, researchers at the University of Latvia, in collaboration with the largest cosmetics manufacturer in the Baltics, H.A.Brieger, have developed a new scientifically based method to determine bioavailable fluoride ions – that is, the actual amount of fluoride released and activated during brushing, which protects the teeth.
Unlike previous methods, this new approach allows for the assessment of the exact amount of fluoride that is actually available to protect the oral cavity during tooth brushing. Fluoride is the only scientifically proven active ingredient that effectively protects teeth against cavities and is recommended by dentists for caries prevention. The development of this effectiveness method is based on the latest international research and adapted to a realistic usage scenario – one minute of tooth brushing, as it occurs in everyday life.
“This method provides a much more accurate understanding of how effectively fluoride-containing products work. It is an important step both from a scientific perspective and for consumer protection,” says project leader Prof. Dr. chem. Artūrs Vīksna.
The study analyzed eight “Dzintars” toothpastes produced by H.A.Brieger, including four from the innovative “Asari” series, as well as four functional toothpastes – whitening, multifunctional, for sensitive teeth, and for healthy gums. The results showed that the bioavailable fluoride content in these products is very high – up to 94% of the total declared amount. Compared to other toothpastes available on the market, where this indicator ranges from 73% to 86%, the “Dzintars” products demonstrate significantly higher effectiveness.
Anastasija Udalova, co-owner and director of H.A.Brieger, states: “The fact that Dzintars toothpastes have received such high recognition is a great satisfaction for our entire team – especially for our chemists and product development specialists. It proves that products can be created right here in Latvia that not only meet but even exceed international quality standards. I am particularly pleased with the University of Latvia’s responsiveness to our initiative to conduct this study – I believe the results will have far-reaching and positive impacts.Firstly, the newly developed method for determining fluoride content will allow for an even more precise assessment of toothpaste quality and will enhance the competitiveness of Dzintars oral care products both in Latvia and in export markets. Secondly, it will strengthen the prestige of Latvian scientists in the international academic and innovation arenas.”
The Dzintars range already includes 10 toothpastes. The functional toothpaste line features four products – specially whitening, multifunctional, for sensitive teeth, and for healthy gums. Meanwhile, the innovative Asari toothpaste series offers four products distinguished by particularly vibrant flavors: quince-apple, blackcurrant, orange, and rhubarb. Additionally, there are two types of Mazirbe toothpastes available for children.
