NCT04124068

Brief Summary

This is a 30 day randomized, parallel comparative trial where participants with tooth shade of C2 or darker will be assigned to one of five groups. The participants will be evaluated for the difference in tooth shade, as determined by the digital VITA Easyshade V (provided by GLO) before the respective whitening regimen (baseline), immediately following the treatment period, and at 30 days (\~4 weeks) from end of the treatment intervention.

  • Be 18 to 65 years of age.
  • Agree not to participate in any other oral/dental product studies during the trial.
  • Agree to delay any elective dentistry (including dental prophylaxis) until the study has been completed.
  • Agree to refrain from the use of any other teeth whitening products once assigned to a treatment group.
  • Agree to refrain from the use of any oral care products that may cause staining (chlorhexidine rinses, stannous fluoride toothpaste, etc.).
  • Agree to return for all scheduled visits and follow study procedures.
  • Be in good general health, as determined by the investigator/designee based on a review of the health history/update for participation in the study.
  • Have at least 4 gradable maxillary anterior teeth ( canine to canine) with a Vita Shade average score of C2 or darker.
  • Be willing to refrain from consuming stain-causing food and beverages (i.e., coffee, tea, red wine, berries, etc.) during the initial treatment duration (treatment period excluding the 4 week follow up).
  • Be a current or recent non-smoker (no smoking for at least 3 months).

You may not qualify if:

  • Are undergoing treatment for gingivitis, periodontitis, or caries.
  • Presence of self-reported tooth sensitivity.
  • Present with fixed orthodontic appliances on the facial surfaces of the maxillary arch.
  • Have dental crowns, veneers or composite restorations on gradable maxillary anterior teeth ( canine to canine) or mandibular anterior teeth.
  • Have any oral pathologies or gross neglect of home care requiring prompt treatment, including periodontal disease, as evidenced by purulent exudate, exposed root surfaces (generalized recession), tooth mobility, and/or other signs indicating that the integrity of the data collected for that subject might be compromised.
  • Present with any pre-existing oral or medical condition that the Investigator/designee determines may place the subject at increased health risk from study participation.
  • Have meaningful malocclusion that would impact treatment or ease of viewing/scoring maxillary anterior teeth.
  • Have teeth with severe or atypical intrinsic staining, such as that caused by tetracycline, fluorosis or hypocalcification.
  • Have any known allergies to over-the-counter oral hygiene/whitening products.
  • Have any known allergies to the trial product ingredients.
