a study of virtually supervised mouthwash and interdental brushes

Conditions: Healthy

Summary: the purpose of this study is to assess the relative effectiveness of oral (mouth) care regimens for the avoidance and treatment of plaque and gingivitis.


Eligibility criteria:
inclusion criteria: * able to comprehend and follow the requirements and restrictions of the study (including willingness to use the assigned study products per instructions, availability on scheduled visit dates and likeliness of completing the clinical study) based upon research site personnel's assessment * evidence of a personally signed and dated informed consent document indicating the participant has been informed of all pertinent aspects of the trial * able to read and understand (participants capable of reading the documents) * able to schedule once daily virtual session during weekdays during the first three months of the study (up to visit 3) and then three times a week for the remainder of the study for interdental brush use and rinsing in real time via a platform such as zoom, facetime, google meet, etcetera (etc) * adequate oral hygiene (that is, brush teeth daily and exhibit no signs or oral neglect) * males and females in good general and oral health without any known allergy to commercial dental products or cosmetics * evidence of being fully vaccinated for corona virus disease-2019 (covid-19) (adults 60 years and older) * negative pregnancy urine tests (females of childbearing potential only) * females of childbearing potential must be using a medically-acceptable method of birth control for at least one month prior to visit 1 and agree to continue using this method during their participation in the study * 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 * participants should have a minimum of 20 interproximal areas where interdental brushes can be inserted * all interproximal sites must be able to accommodate an interdental brush * a minimum of 10 percent (%) bleeding sites based on the expanded bleeding index (bi) * participants will have evidence of some gingivitis (mild to severe); there will be no minimum or maximum mean modified gingival index (mgi) score for gingivitis or turesky modification of the quigley hein plaque index (tpi) score for plaque * no more than 3 sites having pocket depths of 5 millimeters (mm) and no sites that are greater than 5 mm in depth * 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 advanced periodontitis based on a clinical examination at baseline and discretion of the dental examiner * absence of dental implants, fixed or removable orthodontic appliance or removable partial dentures or other appliances which may interfere with supervised interdental brushing exclusion criteria: * history of significant adverse effects, including sensitivities or suspected allergies, following use of oral hygiene products such as toothpastes, mouth rinses and red food dye; known allergy or sensitivity or history of significant adverse effects to any of the investigational product and/or product ingredients or other ingredients in the products * dental prophylaxis within four weeks prior to baseline visit * history of medical conditions requiring prophylactic antibiotic coverage prior to invasive dental procedures * use of antibiotics, 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 * use of chemotherapeutic anti-plaque/anti-gingivitis products such as triclosan, essential oils, cetylpyridinium chloride, stannous fluoride or chlorhexidine containing mouthwashes and toothpastes within four weeks prior to baseline * regular consumption of probiotic drinks/supplements within one week prior to screening/baseline; * 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) * self-reported smokeless tobacco user including snuff, chewing tobacco, vaping and e-cigarette usage * suspected alcohol or substance abuse (example, amphetamines, benzodiazepines, cocaine, marijuana, opiates) * significant unstable or uncontrolled medical condition which may interfere with a participant's participation in the study, including cancer, chronic kidney disease, chronic obstructive pulmonary disease (copd), immunocompromised state (weakened immune system) from solid organ transplant, serious heart conditions, (such as heart failure, coronary artery disease, or cardiomyopathies) sickle cell disease, type 1 or 2 diabetes mellitus) * participation in any clinical trial within 30 days of baseline visit * participants who were previously screened and ineligible or were randomized to receive investigational product * participants who are related to those persons involved directly or indirectly with the conduct of this study (that is, principal investigator, sub-investigators, study coordinators, other site personnel, employees of johnson \& johnson subsidiaries, contractors of johnson \& johnson, and the families of each) * 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 participant inappropriate for entry into this study * covid-19 restrictions: participants who fail to meet the criteria of the site's screening consent for preventing infection in the site's covid-19 consent form
