Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To determine if flossing with a dental floss presoaked in chlorhexidine, an anti-microbial mouth wash, would improve the clinical signs of gingivitis, an inflammation of the gums characterized by red, swollen, bleeding gums. And to determine if applying chlorhexidine via dental floss would result in tooth staining, which is common with chlorhexidine mouthwashes.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Purpose of study: To determine if dental floss presoaked in 0.12% chlorhexidine is more effective at reducing the signs of gingivitis, such as bleeding, than a dental floss in placebo solution of 0.1% quinine sulphate.

Trial design: The study will consist of a double-blinded, placebo-controlled parallel three-month clinical trial.

Randomization of subjects into study groups: Subjects randomized with a computer-generated randomization table and balanced block design to make the two groups equal in number of subjects.

Trial schedule:

1. Screening for potential subjects \& consent obtained. Calibration of examiner.
2. Week -1: Professional prophylaxis consisting of scaling and polishing.
3. Week 0: Baseline data (GI, SI, PI, BOP, PD) collected on subjects enrolled into the study. OHI - flossing. Subject randomized into a study group.
4. Week 6: Subjects reassessed for GI, SI, PI, BOP, PD. Compliance check. Replenish floss supply. Subject concerns or questions addressed.
5. Week 12: Subjects reassessed for GI, SI, PI, BOP, PD. All floss boxes and logbook returned. Subject concerns or questions addressed. Subject exited from study and returned to the care of his or her regular dental professional.

Measurements for data collection (done in this order):

1. Gingival index (GI) (modification of Löe \& Silness, 1963)
2. Stain Index (SI)
3. Plaque index (PI) (modification of Silness and Löe, 1964)
4. Bleeding on Probing (BOP)
5. Probing Depth (PD)
