To Evaluate Efficacy and Tolerability of Sodium Bicarbonate Toothpaste and Its Effect on Opportunistic or Resistant Organisms

Oral Hygiene Clinical Trial

Official title: A Six Month Clinical Study Based in the US to Evaluate the Efficacy and Tolerability of Sodium Bicarbonate Toothpaste and Its Effect on Opportunistic or Resistant Organisms

Status Completed

Clinical Trial Summary

This study will 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 Salus Research, Inc. Participants will be recruited from their database and by use of an external recruitment agency

Clinical Trial Description

This study will be a single-centre, examiner blind, two treatment, parallel group, stratified (by baseline number of bleeding sites smoking status and bacterial sampling) randomized clinical study. At the screening visit, following provision of written informed consent, eligible participants will be provided with a standard toothpaste and toothbrush for brushing once in at the clinic and for approximately one week use at home until the baseline visit. Participants will be asked to abstain from brushing over a 12 hour period prior to the Baseline visit. At the baseline visit an oral soft tissue (OST) assessment, Modified Gingival Index (MGI) and Bleeding Index (BI), and then dental plaque assessment will be performed. Participants will be stratified according to their baseline number of bleeding sites, smoking status and whether selected for bacterial sampling. Participants will be then randomized into one of two treatment groups. After using, their assigned treatment twice daily at home for 6 weeks (visit 3), 12 weeks (visit 4) and 24 weeks (visit 5), participants will return to the site with overnight plaque at approximately the same time of day as the Baseline visit if possible. Participants will undergo a full OST examination and the recording of any Adverse Events (AEs). Participants will then undergo MGI, BI followed by dental plaque assessment. Microbiological samples will be collected on a subset of 50 participants (Determined by first 50 participants randomized). ;
