World-renowned oral healthcare expert joins Sigrid’s SAB to investigate impact of the SiPore® technology on both the oral microbiome and systemic inflammatory conditions


Stockholm, Sweden, May 9th 2023. Sigrid Therapeutics (Sigrid), a Swedish consumer-centric Healthtech company today announced it has appointed world-leading oral health expert Professor Iain Chapple from the University of Birmingham’s College of Medical and Dental Sciences to its Scientific Advisory Board.


Professor Chapple will together with his research group at the University of Birmingham identify and develop further applications for the revolutionary SiPore® technology. Already being described as one of the most important innovations since fluoride, SiPore® is a patented technology that consists of precisely engineered silica particles that can be added to various oral health products to limit oral bacteria’s access to sugars and their ability to form dental biofilm. Professor Chapple and his group at Birmingham’s College of Medical and Dental Sciences will now investigate SiPore®’s broader potential beneficial impact on both the oral microbiome and systemic inflammatory conditions.


Professor Chapple commented: “This was a very easy decision, having seen the technology, scientific portfolio and safety data, it was clear that the potential oral and systemic health benefits of SiPore® are tangible and could be field changing. I was particularly drawn by the physical rather than chemical mode of action of the technology, its flexibility and broad functionality, which could significantly impact the oral as well as the gut microbiome in a positive manner. Taken together the arguments for significant health benefits are compelling and there is some exciting science to be done.”


Professor Tore Bengtsson, Sigrid co-founder and CSO, and the inventor behind the SiPore® technology added: “Through my own research into diabetes, I knew of the connection between bad metabolic health and bad oral health. We are therefore excited to work with Iain and his team to explore the possibility of using our technology to help lessen the burden of sugars in the mouth and improve both related conditions.”


Damir Konakovic, Head of Sigrid’s Oral Health Division added: “By effectively removing amylase, SiPore® decreases the availability of sugar and restricts the growth of pathogenic bacteria and the formation of dental biofilm and plaque. Therefore, as a dentist myself, I believe SiPore® could be one of the biggest innovations in preventative oral health since fluoride. However, in recent years Professor Chapple and others have already shown the links between poor oral health and other systemic metabolic diseases. Which opens even wider potential applications for SiPore®.”


SiPore® is composed of micron-sized silica particles, which are a type of synthetic amorphous silica (SAS). Naturally sourced and environmentally friendly, SAS is tasteless and odorless. It is approved as a food additive, GRAS-listed (generally recognized as safe) and is widely used in foods, cosmetics, and pharmaceutical formulations. This means SiPore® offers the potential to be applied via a variety of consumer/patient-friendly formats.


“It’s an honor to welcome Prof. Chapple and his team at the University of Birmingham to Sigrid. Meeting them has cemented our vision for SiPore®,” says Sana Alajmovic, Sigrid’s Co-Founder and CEO. “The links between oral health and inflammatory disease show that SiPore® is a truly innovative technology that can make a major impact across a range of inter-related health conditions.”


The appointment was made through the Academic Consultancy Service, which is run by University of Birmingham Enterprise, and makes the expertise and knowledge of the University’s academics available to industry, non-profit organizations, public sector organizations and governments.
