Clinical Efficacy of the Combined Effect of Oral Irrigator and Chemicals (0.075% CPC)

Colgate Palmolive30 enrolled

Overview

This is an experimental gingivitis clinical study to evaluate gum health efficacy from the combination effect of water flosser and chemistry (0.075% CPC) compared to water flosser and water and to no oral hygiene regimen with a 3-week follow-up. Thirty participants, aged between 18 and 70, will be enrolled.

This is an examiner blind, randomized controlled, parallel designed clinical study that aims to assess the gum health efficacy (antiplaque and antigingivitis) from the combination effect of water flosser and chemistry (0.075% CPC) compared to water flosser and water and to no oral hygiene in a 3-week experimental gingivitis. Thirty participants will be enrolled and allocated into 3 groups: group I - using a water flosser device and water each time; group II - using a water flosser device and dilutable chemistry product (0.075% CPC) after dilution each time (for groups I an II participants will use this regimen treatment twice daily, in the morning and evening, and no other oral hygiene will be allowed during the 21 days of follow-up); group III - negative control in which participants will abstain for any oral hygiene during the 21 days of follow-up. Gingival index measurements will be the primary efficacy variable after using the assigned regimen for 3 weeks for each subject. Subjects will under go baseline, 3 days, 1, 2 and 3 weeks visits. An Analysis of Covariance will be performed on the final or delta plaque scores using the baseline value as covariate. The F-test in this analysis will test the hypothesis that the waterflosser groups are equal in adjusted means.

Outcomes

Primary Outcomes

Löe-Silness Gingival Index

A Löe-Silness Gingival Index score from 0 to 3 (0 = absence of inflammation and 3 = severe inflammation) will be assigned by the examining dentist to all scorable surfaces of the maxillary and mandibular teeth (6 sites/tooth) 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 scorable surface and dividing that number by the total number of surfaces scored.

Time frame: 3 weeks

Secondary Outcomes

Navy Plaque Index, Rustogi Modification

The dentition will be disclosed with disclosing solution and plaque scored according to the Refined Navy Plaque Index. This index includes nine surfaces (marked A-I) examined for plaque after staining. Surfaces A, B, C denote the gingival margin surfaces, surfaces D and F the proximal surfaces. The total plaque score range is 0-9, the range for the gingival margin area is 0-3 and for the proximal area 0-2.

Time frame: 3 weeks
