As well as studies using standardised protocols, it is also important to conduct studies that take into account the individual behaviour of the participants. Therefore, studies should be also conducted with established private dental practices in particular, and subjective parameters recorded. People are more likely to use a dental product if they really like it. Products should contain further active ingredients which are individually tailored according to individual needs.
How effective are toothpastes containing hydroxyapatite in reducing dentin hypersensitivity when used daily?
Materials and methods
46 persons in total were recruited in three private dental practices. These individuals used a toothpaste containing hydroxyapatite over a period of 4 weeks. Questionnaires were completed at the beginning and the end of the study. These questionnaires recorded their subjective perception not only of tooth sensitivity, but also tooth smoothness and colour before and after the use of toothpaste containing hydroxyapatite.
The toothpaste with hydroxyapatite significantly improves dentin hypersensitivity. It also leads to brighter (whiter) teeth. There was also a significant positive influence on tooth smoothness.
A toothpaste containing hydroxyapatite is suitable for daily use and improves dentin hypersensitivity. Teeth also feel smoother and appear whiter after the use of a hydroxyapatite-toothpaste.
