| Popis: | Honey is a sweetening agent affecting dental caries like sucrose. It contains also a solubility-reducing agent, an organic phosphorus ester that is degradable by salivary emzymes. In the experimental design the changes of microhardness in prepared enamel surfaces from extracted human teeth were monitored by measurements of the tooth enamel microhardness at baseline and after intra-oral exposure, during a certain time period, to honey. Normal and salivary flow deficient subjects volunteered for the study. pH measurements of saliva were carried out at baseline, during and after exposure of the enamel specimens in the mouth to the honey. The pH of the saliva (close to 7.0 at start) mixed up with that of the honey (3.9), decreased from about 6 to 4 in the saliva-honey mixture. After swallowing the mixture the pH returned to the baseline value. The microhardness of the surface enamel did not change in subjects with almost complete lack of saliva flow (dry-mouth subjects), as opposed in the subjects with a regular flow of saliva. |
