Comparative Study of CPC+Zn Mouthwash, Dental Floss, and Essential Oils Mouthwash on Plaque and Gingivitis Reduction

Colgate Palmolive120 enrolled

Overview

Clinical study evaluating the effectiveness of an alcohol-free mouthwash containing CPC+Zn compared to dental flossing and an essential oils-containing alcohol mouthwash in reducing dental plaque and gingivitis. This is a Phase III, single-center, double-blind trial with a parallel design. It involves 120 participants aged between 18 and 65, randomized into different groups, and spans 12 weeks.

This clinical study aims to evaluate the efficacy of an alcohol-free mouthwash containing CPC (Cetylpyridinium Chloride) and Zinc (Zn) in reducing dental plaque and gingivitis compared to dental flossing and a mouthwash with essential oils in an alcohol base. It is a Phase III, randomized, double-blind, parallel-group trial involving 120 participants aged 18 to 65. Subjects will be divided into three 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.

Outcomes

Primary Outcomes

Modified Gingival Index

The Modified Gingival Index (MGI) is a clinical assessment tool used to evaluate the severity of gingivitis by measuring the extent of gingival inflammation. It categorizes gingival health 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.

Time frame: 12 weeks

Secondary Outcomes

Turesky modification of Quigley-Hein Plaque Index

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.

Time frame: 12 weeks

Bleeding on probing

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.

Time frame: 12 weeks

Probing depth

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.

Time frame: 12 weeks
