Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This was a multi-centered (two-sites), examiner-blinded, four treatment arms, stratified (by Modified Dry Mouth Inventory [DMI] score), randomized, parallel group study in participants with self-reported dry mouth symptoms as determined by participant responses to the DMI. Participants used their assigned dry mouth treatment at home for 28 days.

EXPERIMENTAL: OralBalance moisturizing gel
All the participants in this arm used an experimental Oralbalance gel as instructed under the supervision of trained site staff on their visits.
Device: Experimental Oralbalance Moisturizing Gel
Participants placed approximately a half inch length of the gel onto the tongue and spread thoroughly using their tongue. Participants used their assigned treatment products for 28 days as specified on their diary/instructions, at least twice and no more than 5 times daily.
EXPERIMENTAL: Oral rinse
All the participants in this arm used an Oral rinse as instructed under the supervision of trained site staff on their visits.
Device: Biotene Original Oral Rinse
Participants rinsed their mouth with 15 milliliters (mL) of oral rinse for 30 seconds and spat out. Participants used their assigned treatment products for 28 days as specified on their diary/instructions, at least twice and no more than 5 times daily.
EXPERIMENTAL: Moisturizing mouth spray
All the participants in this arm used a moisturising mouth spray as instructed under the supervision of trained site staff on their visits.
Device: Biotene Moisturizing Mouth Spray
Participants sprayed one jet directly into their mouth. Participants used their assigned treatment products for 28 days as specified on their diary/instructions, at least twice and no more than 5 times daily.
SHAM_COMPARATOR: Water only use
All the participants in this arm used water as instructed under the supervision of trained site staff on their visits.

Participants were allowed to take only one measured sip of water (15 mL) 30 minutes before the supervised product use. After the supervised treatment at the site, participants assigned to the water only treatment were allowed to sip water as often as required.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Modified Product Performance and Attributes Questionnaire I (PPAQ I) (Question Number 1: Relieving the Discomfort of Dry Mouth)
