Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The following mouthrinses will be evaluated:
-Group A: containing Propolis resin extract (1:3), Plantago lanceolata leaves extract (1:10), Salvia officinalis leaves extract (1:1) and 1.75% of essential oils from Salvia officinalis, Syzygium aromaticum buds, Mentha piperita leaves, Commiphora myrrha oleoresin and Pistacia lentiscus oleoresin (Fitomedical snc, Binasco, Milan, Italy).
- Group B: containing 0,09% of chlorhexidine (CHX) and CITROX® (formulation deriving from the extract of bitter orange peel) (Curaprox Italia S.r.l. , Bolzano, Italy).
The patients will use the assigned mouthrinses twice a day for two weeks. At baseline a single examiner , with more than 8 years of practice, will collect the clinical parameters. All patients will receive a written instruction of the tested mouthrinses and their right dosage. The participants will be instructed to gargle 10 ml of the mouthrinse for a period of 60 seconds, after which the mouthrinse is spit out. Moreover, they will be instructed to not rinse/eat anything for 30 minutes after mouthrinse use. The patients will continue to perform their routine oral home care, adding only the assigned mouthrinse. Patient self-report diary will be use to monitor adherence of the patient to intervention.

Efficacy
Statistical methods / analysis
This study will be a single-center, randomized, double-blind, parallel-group clinical trial. Calculation of number of subjects will be centred on the principal outcome, i.e. the difference of full mouth bleeding score (FMBS) values between groups. Group sample sizes of 25 achieve 80% power to detect non -inferiority using one-sided, two sample equal-variance t-test. The margin of non-inferiority is -4.0. The actual difference between the means is assumed to be 0.0. The significance level (alpha) of the test is 0.05. The data are drawn from populations with standard deviation of 5.0 in both groups. Since an attrition of 10% of the subjects is assumed, 82 subjects will planned to be included

Summary
Brief summary
Dental plaque is a biofilm of microorganisms found on a tooth surface, embedded in a matrix of polymers of host and bacterial origin. The presence of dental plaque can provoke gingivitis and periodontitis. This work aims to evaluate the non-inferiority of two different mouthrinses, one synthetic and one natural, respect on a mouthrinse gold standard as an aid for home oral hygiene.
