Detailed Description

The present clinical study aims to investigate the clinical efficacy of 5 mouthwashes based on different active substances. The study include 180 patients divided into 6 groups of 30 patients, each group rinse with one of the following mouthwashes - mouthwash based on essential oils (menthol, thymol and eucalyptus), mouthwash based on essential oils (menthol, thymol and eucalyptus) and 0.12% chlorhexidine, mouthwash based on 0,8 % hydrogen peroxide, mouthwash based on prebiotic, water based on 0.2% chlorhexidine, placebo mouthwash. Inclusion criteria are: generalized gingival inflammation, plaque index of Turesky, 1970 > 1.95, gingival index of Loe & Silness, 1963 > 0.95, no systemic diseases, no systemic medication, lack of severely damaged teeth, no large fillings, no orthodontic treatment. Patients are motivated and instructed to maintain proper and optimal personal oral hygiene. All participants undergo professional mechanical plaque removal. After instrumentation participants are instructed to rinse with 15 ml mouthwash 2 times a day for 21 days. Researchers control the amount of mouthwash used by giving a new bottle of mouthwash with the required amount for 1 patient for 1 week at the beginning of each week and taking back the bottle from the previous week. During the study period, patients are monitored on days 14 and 21, examining plaque index of Turesky, 1970, gingival index of Loe & Silness, 1963, bleeding index of Ainamo & Bay, 1975, side effects like staining, burning itching, oral lesions. At the end of the study (day 21), patients complete a questionnaire.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change from baseline bleeding index at 21 day.
Time Frame: 21 days
Recording the bleeding index of Ainamo&Bay, 1975. The index reports the presence or absence of bleeding on probing in 4 sites around every tooth. It is calculated in % for the whole dentition.
21 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change from baseline gingival index at 21 day.
Time Frame: 21 days
The gingival index of Loe, 1967 estimates the inflammation of the gingiva in 4 sites around every tooth, examining the colour, the texture, the consistency and the bleeding of the gingiva.
21 days
Change from baseline oral hygiene index at 21 day.
Time Frame: 21 days
The index of Turesky, 1970 is used. After discolouration of the plaque its distribution is measured in 6 sites of every tooth. The mean value is calculated by summing the individual values for each tooth and dividing the sum by all the places examined.
