1. Challenge Testing using Streptococcus mutans and Porphyromonas gingivalis

A number of different dental substrates were received for challenge testing against the organisms Streptococcus mutans and Porphyromonas gingivalis. (Both of these bacteria are commonly found in the mouth, and are regarded as significant contributors to tooth decay and bad breath.) The samples were labelled as follows:   Read more...

2. Analysis of Dental Powder

A dental powder was received at the laboratory for bacterial challenge testing against the organism Streptococcus mutans. Streptococcus mutans is commonly found in the mouth, and is a significant contributor to tooth decay. The sample was labelled as follows:   Read more...

3. Longer Exposure Testing Analysis of Dental Powder

A dental powder previously received at the laboratory for bacterial challenge testing against the organism Streptococcus mutans was further analysed over a longer period of time. (Streptococcus mutans is commonly found in the mouth, and is regarded as a significant contributor to tooth decay.) The sample was labelled as follows:   Read more...

5. Product Information on Betaine

Our aim was to study the effects of mildly flavoured sodium laurylsulphate (SLS) – containing and detergent-free toothpastes with and without betaine (BET) on subjective symptoms of dry mouth in a randomised clinical trial. BET is an osmoprotectant that reacts with molecules to supply the surface with a water coating that protects cells from surfactants. Twenty-seven xerostomic patients and 18 healthy controls took part in the randomised, double-blind clinicla trial with a corssover design   Read more...
