Research & Media

Dr Pirjo Pärnänen (Associate Professor in Oral Microbiology, DMD, PhD) has been researching fermented lingonberry juice for over 15 years, and has conducted a number of clinical studies with impressive outcomes.

Lingora® is a class I registered medical device in the UK and EU and carries the EUDAMED ID 06429811111004.

 

Results of studies are outstanding

Laboratory and clinical studies have shown a reduction in dental plaque and bleeding of the gums, and additionally antimicrobial, anti-inflammatory, anti-cancerous, and antioxidant properties. Caries-related Streptococcus mutans and candidosis- related Candida levels are reduced as well as periodontal disease- related pathogen levels. Levels of lactobacilli on the other hand are increased, which is thought to be a beneficial probiotic effect balancing the oral microbiota.
