Fluoride has been central to the prevention and management of caries for many years, but a shift is needed in the way it is delivered. Enter BioMin® F, a new, smart way to protect teeth and manage the symptoms of dentine hypersensitivity.

This was the theme of a webinar talk given by Dr Swati Nehete, Senior Clinical Lecturer in Restorative Dentistry at Queen Mary University of London, and a Clinical Advisor to BioMin Technologies.

Speaking at an FMC Study Club webinar in the depths of the COVID-19 lockdown, Dr Nehete gave her lecture over the internet to an astonishing 2,000+ strong audience from 63 countries, all tuning in from their own homes to hear her speak. An overview of her presentation appears in the latest issue of Dentistry Magazine.

In a presentation packed with information, Dr Nehete introduced her listeners to the background to bioactive glass, the development of BioMin F at Queen Mary University of London, and its action, dissolving slowly over a period of up to 12 hours to release fluoride, phosphate and calcium ions to deposit fluorapatite, the fluoride analogue of natural tooth enamel. The smart aspect of BioMin F’s action refers to the fact that it starts to dissolve sooner in an acidic environment, protecting the teeth.

Using diagrams and impressive scanning electron micrograph images, she illustrated how BioMin® is able to enter and occlude the dentinal tubules, effectively preventing the fluid flow that causes dentinal hypersensitivity.

BioMin has a wealth of studies behind it, and Dr Nehete quoted extensively from these, particularly highlighting one which concluded: ‘[BioMin] may provide better treatment response for the treatment of dentine hypersensitivity because of its early onset of action in relieving hypersensitivity, as compared with other dentifrices.’

In line with the FDI (World Dental Federation) guidelines, which ‘support a shift in caries management from restorative treatment to measures that arrest and prevent caries development’, she also showed data proving that BioMin F was more effective at remineralisation than standard products. She concluded that BioMin, effective at just 530ppm fluoride, was an innovative alternative to high concentration fluoride, thanks to the addition of calcium and phosphate – especially at this moment in history. ‘COVID-19 will force the profession to review current practice in favour of preventive and minimally invasive dentistry (MID)’, she said.

Time was left at the end of the webinar for the many questions that arose, and which Dr Nehete answered in detail. Afterwards she said she enjoyed the opportunity to interact with her audience. ‘That Q&A is so important for something as new as BioMin and it was good for me to get a feel for whether people “got” what I had to say.’ She added: ‘They are an intelligent audience who want to know why this is the next big thing. We owe it to them to make it as clear as possible.’

She is personally very excited by BioMin’s possibilities. ‘I have been involved in the many stages of BioMin’s development and I have a genuine interest in it,’ she said. ‘I think it has the potential to go places – it’s an innovative solution to an age-old problem – using accepted science more smartly. It’s got fantastic potential.’
