Comparative Study to Evaluate the Efficacy of an Alcohol-free Mouthwash Regimen With CPC+Zn, Flossing and Brushing, and an Alcohol-based Mouthwash Regimen With Essential Oils in Reducing Plaque and Gingivitis.

Phase 3

Completed

• Conditions: Gingival Bleeding; Plaque Induced Gingival Disease; Gingival Diseases; Gingivitis and Periodontal Diseases
• Interventions: Drug: Mouthwash CPC+Zn+F; Drug: Essential oils mouthwash; Device: Dental floss

• Registration Number: NCT06598072
• Lead Sponsor: Colgate Palmolive

Brief Summary

This is a Phase III, randomized, one-center, parallel group, double blinded, clinical study to evaluate the efficacy of an alcohol-free mouthwash containing CPC+Zn as compared to dental flossing and to rising with an essential oils containing alcohol mouthwash in reducing dental plaque and gingivitis. One hundred and twenty participants, aged between 18 and 65 years, will be included and followed for 12 weeks.

Detailed Description

This clinical study aims to evaluate the efficacy of a regimen including an alcohol-free mouthwash containing CPC+Zn as compared to dental flossing and brushing and to a regimen including a rinsing with an essential oils containing alcohol mouthwash in reducing dental plaque and gingivitis. This is a Phase III, randomized, one-center, parallel group, double blinded, involving 120 participants, aged 18 to 65. Subjects will be allocated into 3 groups: one - using the CPC+Zn mouthwash, another using the essential oils mouthwash and a control group using dental floss. Each group will also use a fluoride toothpaste and a soft-bristle toothbrush twice daily over 12 weeks. The primary efficacy variable is the reduction of gingival inflammation also Probing Depth, Bleeding on Probing, and a Plaque Index will be accessed. Subjects will undergo baseline, 4-week, and 12-week evaluations, with data analyzed using ANCOVA to assess the efficacy and safety of the products. Adverse events and compliance will be closely monitored, with strict confidentiality maintained for all participants. The study rigorous design aims to provide comprehensive insights into the effectiveness of these oral hygiene regimens.

Arm && Interventions

Group	Intervention	Description
CPC+Zn mouthwash and brushing	Mouthwash CPC+Zn+F	A regimen composing of a CPC+Zn mouthwash, brushing with a commercially available toothbrush and a stannous fluoride-based toothpaste
Essential oils mouthwash and brushing	Essential oils mouthwash	A regimen composing of an essential oils mouthwash, brushing with a commercially available toothbrush and a fluoride-based toothpaste
Flossing and brushing	Dental floss	A regimen composing of flossing and brushing with a commercially available toothbrush and a fluoride-based toothpaste

Primary Outcome Measures

Name	Time	Method
Modified Gingival Index	12 weeks	The Modified Gingival Index (MGI) is used to evaluate the severity of gingivitis by measuring the extent of gingival inflammation. It categorizes gingival health/inflammation on a scale from 0 to 4, where 0 signifies normal gingiva with no inflammation, and 4 indicates severe inflammation characterized by erythema, edema, and spontaneous bleeding.

Secondary Outcome Measures

Name	Time	Method
Turesky modification of Quigley-Hein Plaque Index	12 weeks	The Turesky modification of the Quigley-Hein Plaque Index is a method for assessing dental plaque accumulation by scoring plaque presence on six surfaces of each tooth on a scale from 0 to 5.
Bleeding on probing	12 weeks	Bleeding on probing (BOP) is a diagnostic technique used to assess gingival inflammation by gently probing the gum tissue; the presence of bleeding indicates inflammation and potential periodontal disease.
Probing depth	12 weeks	Probing depth measures the distance between the gingival margin and the bottom of the periodontal pocket using a calibrated periodontal probe, indicating the severity of periodontal disease.
