Periodontal Diseases Clinical Trial

Official title: The Anti-inflammatory and Anti-plaque Efficacies of Mouth Rinse Containing Hyaluronic Acid and Hydrogen Peroxide in the Management of Dental Biofilm-induced Gingivitis: a 14 Days Randomized Clinical Trial

Status Completed

Clinical Trial Summary

The goal of this clinical trial is to test efficiency of using mouth rinse containing (H2O2 and HA) over a period of two weeks to control on gingival inflammation and plaque accumulation through measuring the clinical periodontal parameters (Gingival Index (GI), Bleeding on probing (BOP) and modified Quigley-Hein Plaque Index (mQHPI ) in comparison with Chlorhexidine (CHX) and placebo mouth rinses in patients with biofilm induced gingivitis. Objectives: - Evaluate the clinical efficiency of using mouth rinse containing (H2O2 and HA) over a period of 14 days to control on gingival inflammation and plaque accumulation through measuring the clinical periodontal parameters (Gingival Index, Bleeding on probing and modified Quigley-Hein Plaque Index in comparison with Chlorhexidine and placebo mouth rinses in patients with biofilm induced gingivitis. - Measuring levels of salivary cytokines, Interleukin 1 beta (IL-1B) and Interleukin 6 (IL-6) at baseline visit before using mouth rinse and after 14 days of using the mouth rinse containing H2O2 and HA compared to chlorhexidine and placebo mouth rinses. - Evaluate subjects' perception of a mouth rinse (H2O2 and HA), CHX and placebo mouth rinses after 14 days from using three mouth rinse

Clinical Trial Description

54 subjects will be enrolled, who show with generalized gingivitis (having >30% bleeding sites with no PPD >3 mm, intact periodontium and no loss of periodontal attachment), caused by accumulation of plaque. A double-blind, randomized parallel 3-arms clinical trial include using the following mouth rinses, 0.12% CHX (KIN Gingival, KIN, Barcelona, Spain) as positive-control , distilled water (placebo, nonactive control) with food additives (to blind the subjects and examiner) and Perhyal rinse (BMG Pharma, Milan, Italy ) containing has H2O2 (1,80%) and HA (0,10%) with the remaining part being water (97,3%) and inert additives as active ingredients, will be used as test interventions. The mouthwashes will be contained in identical opaque bottles that were randomly given sequential letters codes (A, B and C ) by a another subject who will not involved in the clinical investigation. This ensured the double blindness of both the participant and examiner during the clinical trial. Decoding will performed after the end of the study. Randomization will be performed by the examiner for enrollment patient in 3 groups. Each group will be assigned a letter (A, B or C) corresponding to the intervention used. Random numbers were generated and used to re-sort the order of the groups and participants (n=54), who will distributing into designated groups, each group received a similar number of subjects (n=18) with a 1:1:1 allocation, by using a Microsoft Excel random table (Microsoft Office 2016, Microsoft Corporation, USA). Then, coded bottles with the interventions will be delivered to the participants together with instructions for use. The participants will be asked to rinse with 10 ml of undiluted. mouthwash for 60 s twice per day (30 min after tooth brushing) and will be instructed to refrain from eating and drinking for 30 min after rinsing. Discontinuation of the mouthwash will be advised in cases of any allergic reaction. All participants will be received a toothbrush with medium-hardness bristles and a toothpaste (COLGATE®, Colgate-Palmolive, NY, USA). No modifications to the participants' tooth brushing technique will be permitted. In baseline visit at the beginning, Saliva collection for IL-1β and IL-6 measurement then clinical periodontal parameters examination starting with gingival index (Loe and Silness in 1963) designed to assess the severity and quality of gingival inflammation in an individual or population. The gingival inflammation is assessed on the basis of color, consistency and bleeding on probing. A periodontal probe will be runned along the gingival margin. The gingiva surrounding the tooth is assessed at four sites: mesio-facial papilla, facial marginal gingiva, disto-facial papilla and lingual marginal gingiva. Followed by dryness and wait then measurement of BOP for the six surfaces of all teeth except wisdom teeth through gently inserting the periodontal probe to the depth of the gingival sulcus then removed coronally and waited for 30 s to observe the presence of bleeding (0=no bleeding, 1=presence of bleeding) Then finally followed by the Modified Quigley Hein Plaque Index with Fluorescein disclosing tablets. In the (mQHPI) the data had been recorded from labial/buccal and lingual/palatal surfaces of each disclosed tooth except wisdom teeth and any teeth had filling surface. The distance from the gingival margin to the edge of the disclosed area measured to the nearest 0.5 mm using a calibrated periodontal probe and the scores registered according to record form of mQHPI for each participant. The mean of mQHPI for each participant had been calculated by collecting the scores over the total number of surfaces examined. First visit after 14 days, from the baseline visit. Saliva collection and clinical periodontal parameters scoring (GI, BOP ,mQHP) will be performed again as described at baseline visit. The mouthwash bottles will be retrieved, and the remaining volume will be determining to further evaluate the compliance with mouth rinsing. (the total volume/bottle for two weeks will be 280 ml). For the purpose of self-assessment, a visual analog scale (VAS)- score based questionnaire was filled out by each participant at the end of the trial to evaluate the intervention. The questionnaire and method of data interpretation were adopted and modified from a previous study. ;
