Brief Summary

Xerostomia, is a subjective sensation of dryness of the mouth. There are more than 700 medications that can lead to the salivary hypofunction that results in dry mouth. This study will investigate a semi solid cohesive gel (referred to as Whitening Gel) that has the primary marketed purpose of teeth whitening. We theorize that the whitening gel's retention in the oral cavity is longer than rinse forms and this is likely to promote the flow of saliva by stimulating taste buds which could alleviate the sensation of dryness in the oral cavity. This will be a single center, two visit study investigating the effectiveness of dryness in the oral cavity, whiteness of teeth, and teeth sensitivity after one week's use of whitening agent.

Outcome Measures

Primary Outcomes (1)

  • Subjective Perception of Mouth Dryness

    At both study visits, subjects will be asked to complete a visual analog scale (VAS) before and after the application of the study product to establish a self-reported subjective perception of the oral cavity. The scale ranges from 0 to 10 and the higher the score indicates the more Xerostomic the subject.

    visit 1 and visit 2 pre and post product application on Day 1 and day 7

Secondary Outcomes (2)

  • Change in Saliva Production Measured in ml/Min

    visit 1 and visit 2 pre and post saliva production in day 1 and day 7

  • Perceived Sensitivity of Teeth Between Visit 1 and 2

    7 days between visit 1 and visit 2

Study Arms (1)

All Participants

EXPERIMENTAL

This is a single arm study. All subjects enrolled will be apart of the experimental group. Subjects in this group will use Crest Whitening Emulsions on their teeth up to 4 times a day for 7 days in order for the study team to evaluate if the study intervention product increases saliva production in this Xerostomic population.

Device: Crest Whitening Emulsions

Interventions

Subjects with Xerostomia will be asked to apply the study intervention product to their teeth up to 4 times per day for 1 week to investigate if the study intervention product increases saliva production in this dry mouth populaiton.

All Participants

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • At least 18 years of age.
  • The inability to produce more than 0.18mL/min of unstimulated saliva.
  • Score of 5 or more in the VAS dry mouth scale, evaluated in the mouth feel questionnaire.
  • Evidence of currently taking Xerostomia-inducing medication such as, antihypertensives, anti-anxiety agents, psychiatric remedies, antihistamines.
  • Subject not currently using any teeth whitening or desensitizing products that contain potassium nitrate such as Sensodyne or Pronamel.
  • Subject willing to comply with the study regimen and products.

You may not qualify if:

  • Subjects who are currently pregnant (self-reported).
  • Subjects able to produce more than 0.18mL/min of unstimulated saliva
  • Subjects that have ever received therapeutic radiation in the head and neck area.
  • Subjects with a diagnosis of conditions that would affect salivary flow such as Sjogren's Syndrome.
  • Subjects with a condition the investigator believes not suitable for the study such as autoimmune diseases that impact salivary flow.
  • Subjects that currently use whitening toothpaste, desensitizing toothpaste, or any other products causing similar results.
  • Subjects currently participating in any other research studies.
  • Subject unable to provide consent (ex. Cognitively impaired adults).
  • Non-English speaking
