简要总结
During the current COVID-19 pandemic, the use of face masks is recommended / mandatory to prevent infection. Patients and students have reported to experience limitations in their oral health-related quality of life, especially with regard to the occurrence of dry mouth and halitosis, while wearing face masks.
Scientific studies regarding the effects of face masks have so far focused exclusively on medical staff. Studies among the general population are not yet available, but are of interest as dry mouth is a risk factor for dental diseases (e.g., caries, erosion).
Therefore, the present study aims at measuring the effect of wearing different face masks on salivary parameters (unstimulated and stimulated saliva flow rate, pH, buffer capacity) and halitosis (volatile sulphur compounds).

mL/min
次要结局
- Determination of stimulated saliva flow rate(Each day, prior (between 8 and 9 a.m.) and after wearing a face mask for 4 hours or 4 hours without wearing any mask. Stimulated saliva samples are collected for 5 min while chewing a paraffin pellet.)
- Determination of unstimulated and stimulated saliva pH(Each day, prior (between 8 and 9 a.m.) and after wearing a face mask for 4 hours or 4 hours without wearing any mask. Saliva samples are collected for 5 min each. Stimulated saliva samples are collected while chewing a paraffin pellet.)
- Determination of unstimulated and stimulated salivary buffer capacity(Each day, prior (between 8 and 9 a.m.) and after wearing a face mask for 4 hours or 4 hours without wearing any mask. Saliva samples are collected for 5 min each. Stimulated saliva samples are collected while chewing a paraffin pellet.)
- Determination of volatile sulphur compounds (VSC)(Each day, prior (between 8 and 9 a.m.) and after wearing a face mask for 4 hours or 4 hours without wearing any mask.)
