Various polymer solutions with and without surfactants were evaluated regarding their lubricating properties on the oral mucosa. After rinsing with the solutions, the oral mucosal friction value was registered with a probe (objective effect). After each rinsing occasion at home, the patients answered a questionnaire (subjective effect). None of the tested polymers showed a longer, clinically significant effect than the other ones. Some of them had the same effect as substitutes available on the Swedish market.
