Trial overview

Official title: A Six Month Clinical Study Based in the US to Evaluate the Efficacy and Tolerability of Sodium Bicarbonate Toothpaste
Trial description: The primary objectives of this study will be to compare the Gingival Bleeding and Gingival Inflammation following twice daily use of a sodium bicarbonate experimental dentifrice compared to a 0% sodium bicarbonate toothpaste after 24 weeks of use. The study will be conducted at Silverstone Research Group. Participants will be recruited from their database and by use of an external recruitment agency.
Primary purpose:
Treatment
Trial design:
Parallel Assignment
Masking:
Single (Investigator)
Allocation:
Randomized
Primary outcomes:

Number of Gingival Bleeding Sites at 24 weeks

Timeframe: Baseline, 24 weeks

Modified Gingival Index (MGI) at 24 weeks

Timeframe: Baseline, 24 weeks

Secondary outcomes:

Number of Gingival Bleeding Sites at 6 and 12 weeks.

Timeframe: Baseline, 6 and 12 weeks

Modified Gingival Index (MGI) at 6 and 12 weeks.

Timeframe: Baseline, 6 and 12 weeks

Bleeding Index at 6, 12 and 24 weeks

Timeframe: Baseline, 6, 12 and 24 weeks

Plaque control (overall and interproximal dental plaque scores) using Turesky modification of Quigley & Hein plaque index at 6, 12 and 24 weeks.

Timeframe: Baseline, 6,12 and 24 weeks

    Inclusion and exclusion criteria
    Inclusion criteria:
    • Good general health with (in the opinion of the investigator) no clinically significant and relevant abnormalities of medical history or oral/dental examination.
    • A minimum of 20 permanent gradable teeth
    • Moderate gingivitis present at the screening visit in the opinion of the investigator
    • A total of 20 bleeding sites or greater at baseline visit
    • Positive response to bleeding on brushing present at the screening visit
    Exclusion criteria:
    • Pregnant or breast feeding women
    • Tobacco chewers
    • Current or relevant history of any serious, severe or unstable physical or psychiatric illness or any other medical condition (e.g. Diabetes Mellitus) that would make the participant unlikely to fully complete the study or any that increases the risk to the participants or undermines the data validity.
    • Recent history (within the last year) of alcohol or other substance abuse
    • Participants requiring prophylactic antibiotic treatment prior to dental therapy
    • Known or suspected intolerance or hypersensitivity to the study materials (or closely related compounds) or any of their stated ingredients
    • Have current active caries or any medical conditions which may directly influence gingival bleeding
    • Use of concomitant or any systemic medication that, in the opinion of the investigator, might interfere with the outcome of the study or have an effect on gingival conditions within 14 days of gingival examinations
    • Excessive calculus present that interferes with the probing examination for Gingival Bleeding Index
    • Participation in another clinical study or receipt of an investigational drug or oral care product within 30 days of the screening visit
    • An employee of the sponsor or the study site or members or their immediate family.
