This is a satisfactory result, considering that most of the patients previously cleaned their dentures with conventional pastes. The level of mutans group streptococci and S. mutans was high. These microorganisms have a great influence on the beginning of biofilm formation on dental surfaces. Therefore, the detection of mutans streptococci in dentures is important because of the possibility for disease transmission by these microorganisms. Among yeasts, C. albicans can be considered as a significant pathogenic microorganism.
Microbial adherence is an essential first step in the development of infection.
Although not a significant result, the experimental product caused a reduction of the number of colonies from the 3rd to the 7th visits. The microbiota did not differ among groups. Microbial associations are regularly present on the internal surfaces of complete dentures, even in people with clinically healthy palatine mucosa. These results suggest that it is possible for complete denture wearers to keep their dentures clean with the regular use of a paste-like hygienic product. Moreover, this can be achieved without risk of denture damage.
