Summary:

      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.
    

Eligibility 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.
