About this study
The purpose of this research study is to test the effectiveness of treating dry mouth through water rehydration using this extra oral water pump/irrigation device.
Read the detailed description
Dry mouth causes difficulty with chewing, swallowing, speech, and increases the risk dental cavities. It also can cause discomfort in the mouth, and a loss of general quality of life. The oral irrigation device supplies a small amount of water to participant's mouth through a small tube that is placed in the corner of the mouth throughout the time participants wear it.
In this study, participants will be asked to:
- Visit the dental school clinic two (2) times for study visits.
- Wear the oral irrigation device as directed by the investigator.
- Keep notes at home.
- Answer survey questions during both dental visits about dry mouth symptoms.
- Give permission for the researchers to collect information about medications or health conditions that contribute to dry mouth from participant's medical records.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
The Voutia SystemDevice
Also called Oral irrigation device
Participants will wear the Voutia System oral irrigation device continuously through the day and night, removing for cleaning and if otherwise necessary, but not for time extending beyond six-eight hours.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Oral Health Related Quality of Life (OHRQoL)
OHRQoL will be assess using the Oral Health Impact Profile (OHIP-14). The OHIP-14 scores can range from 0 to 56 and are calculated by summing the ordinal values for the 14 items on the scale. Higher OHIP-14 scores indicate worse and lower scores indicate better OHRQol
Measured: Baseline to 4 - 6 weeks
Change in Oral Health Related Quality of Life - Dry Mouth Specific (OHRQoL-XI)
OHRQoL-XI will be assessed using the Xerostomia Inventory (XI), an 11-item summated rating scale which combines the responses to 11 individual items into a single continuous scale score which represents the severity of chronic xerostomia. Scores range from 11 to 55 with higher scores represent more severe symptoms.
Measured: Baseline to 4 - 6 weeks
Change in Oral Dryness
Clinical Oral Dryness Score (CODS) conducted during the clinical exam assesses ten key features of dry mouth and allocates one point for each feature. The total score ranges from 0 to 10 with higher scores indicating more severe dry mouth.
Measured: Baseline to 4 - 6 weeks
Clinical Changes in Stimulated Saliva Flow
Data on routine stimulated saliva testing as performed as standard of care for patients suspected to have reduced salivary flow will be compared before and after use of the device.
Measured: Baseline to 4 - 6 weeks
Clinical Changes in Unstimulated Saliva Flow
Data on routine unstimulated saliva testing as performed as standard of care for patients suspected to have reduced salivary flow will be compared before and after use of the device.
Measured: Baseline to 4 - 6 weeks
