A Clinical Trial to Test the Effect of Experimental Mouth Rinse on Gum Disease

NCT02065414 | Completed Phase 4

• 1 other identifier: LAEBBA0005
• Study Type: interventional
• Target: 260
• Locations: 1 country
• Sites: 1

Brief Summary

Participants will be given special instructions about taking care of their teeth during the 18 hours before they come to the dentist's office for screening/baseline, 1 week, 2 weeks and 4 weeks. At that first visit, they will be examined by a dentist, who will examine their mouths with a dental instrument to determine whether they qualify to participate in the trial. Someone who works for the dentist will also take some oral measurements. Participants who qualify to be in the study will receive a treatment for their gingivitis and have an equal chance of being assigned to one of three treatment groups. Participants in all three groups will be given toothpaste that is already available in stores. They will brush their teeth twice daily in their regular manner. After brushing, participants in one group will use an experimental mouth rinse that is not available in stores. Another group will be given a mouth rinse to use that is already available in stores, and the third group will use a placebo mouth rinse. After they receive their assigned products participants will be supervised while they brush their teeth and rinse to ensure they understand exactly how to use the products. Participants will be required to stay at the site 20 minutes after the first use of product during visit 1 to monitor any potential allergic reaction. All other brushing and rinsing over the next four weeks will be at home, but participants will be required to keep a diary to record their brushing and rinsing times twice each day. Participants will be required to bring their diaries and any left-over toothpaste and mouth rinse with them for three more scheduled appointments after about 1 week, 2 weeks, and 4 weeks. At those appointments, the dentist will examine their mouths, make sure there are no safety concerns, and examine again to get the measurements needed. One of the dentist's staff members will take other measurements as well. The study will determine the measured effects of the experimental mouth rinse on bleeding as a result of gingivitis, and compare these results to the mouth rinse that is already available.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• \. Males and females 18 years of age or older, in good general and oral health without any known allergy to commercial dental products or cosmetics.
• \. Evidence of a personally signed and dated informed consent document indicating the subject (or legally acceptable representative) has been informed of all pertinent aspects of the trial and all questions have been answered.
• \. Females of childbearing potential must be using a medically-acceptable method of birth control for at least 1 month prior to Visit 1 and agree to continue using this method during their participation in the study.
• \. Able to comprehend and follow the requirements of the study (including availability on scheduled visit dates) based upon research site personnel's assessment.
• \. A minimum of 20 natural teeth with scorable facial and lingual surfaces. Teeth that are grossly carious, extensively restored, orthodontically banded, abutments, exhibiting severe generalized cervical and/or enamel abrasion, or third molars will not be included in the tooth count.
• \. A mean gingival index ≥1.75 according to the Modified Gingival Index.
• \. A mean plaque index ≥1.95 according to the Turesky modification of the Quigley-Hein Plaque Index scored on six surfaces per tooth.
• \. Mean Bleeding Index ≥0.15
• \. Absence of significant oral soft tissue pathology, excluding plaque-induced gingivitis, based on a visual examination and at the discretion of the Investigator.
• \. Absence of moderate/advanced periodontitis based on a clinical examination (ADA Type III, IV).
• \. Absence of fixed or removable orthodontic appliance or removable partial dentures.

You may not qualify if:

• \. History of significant adverse effects, including sensitivities or suspected allergies, following use of oral hygiene products such as toothpastes and mouth rinses and red food dye.
• \. Dental prophylaxis within 2 weeks prior to Screening visit.
• \. History of medical conditions requiring prophylactic antibiotic coverage prior to invasive dental procedures.
• \. Antibiotic, anti-inflammatory or anticoagulant therapy during the study or within the one month prior to the baseline exam. Intermittent use of certain anti-inflammatory medication is acceptable at the discretion of the investigator.
• \. Daily use of aspirin.
• \. Known sensitivity to the investigational product ingredients.
• \. Self reported pregnancy or lactation (this criterion is due to oral tissue changes related to pregnancy and nursing which can affect interpretation of study results).
• \. Significant unstable or uncontrolled medical condition which may interfere with a subject's participation in the study, at the discretion of the Investigator.
• \. Participation in any clinical study within 30 days of Visit 1.
• \. Relative, partner or staff of any clinical research site personnel.
• \. Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the subject inappropriate for entry into this study.
