The Clinical of Stannous Fluoride Toothpaste and a Newly Designed Toothbrush Compared to Colgate Cavity Protection Toothpaste and a Regular Toothbrush in Reducing Plaque and Gingivitis.

Qualified subjects will be enrolled and randomly assigned to either of the two study groups based on their initial Plaque and Gingivitis scores. During the first visit, subjects will undergo three key procedures: 1) evaluation for baseline plaque and gingivitis, 2) brushing with the assigned regimen products for two minutes, and 3) assessment for post-brushing plaque only. Subjects will be provided with clear instructions for regimen product usage and will be expected to adhere to these instructions. Follow-up evaluations for plaque and gingivitis will be conducted at one week, six weeks, and three months after initiation of regimen product use. Throughout the study period, continuous monitoring for adverse events will be carried out for all subjects.

Primary outcomes

  1. Loe and Silness Gingival Index.

    Time frame: baseline, one week, six weeks and three months

    A Loe-Silness Gingival Index score from 0 to 3 will be assigned by the examining dentist to all scoreable surfaces of the maxillary and mandibular teeth using a dental light and dental mirror. A whole mouth mean score for each subject will be determined by adding the values given by the examining dentist to each scoreable surface and dividing that number by the total number of surfaces scored.

  2. Quigley and Hein Plaque Index

    Time frame: baseline, one week, six weeks and three months

    A Quigley-Hein Plaque Index score of 0 to 5 will be assigned to all scoreable disclosed surfaces of the maxillary and mandibular teeth using a dental light and dental mirror. A whole mouth score for each subject will be determined by adding the values given by the dental examiner to each scoreable surface and dividing that number by the total number of surfaces scored.
