Brief summary

Participants between the age of 18 – 35 yrs old that fulfill the inclusion criteria will be chosen to take part in the study. All participants will be randomly assigned to one of six groups 14 days prior to commencement of the study. All the participants will receive a dental clean and will be advised to stop the use of their regular mouthwash. When the experiment begins (day 0) participants will be advised to follow the experimental oral hygiene protocol. And they will be advised to use one of five mouthwashes (or water which is a negative control). Five different gum measurements will be measured and the soft tissue health will be noted at all four visits from the start of the experimental period. At the last visit participants will be requested to fill a questionnaire form as well. In addition they will also receive a dental clean to remove bacterial accumulation on their teeth and extrinsic tooth staining. There is significant evidence in the current literature that commercial alcohol containing mouthwashes such as Savacol (Registered Trademark) and Listerine (Registered Trademark) reduce bacterial accumulation and gum inflammation. However despite some progress, there is a huge gap in clinical evidence demonstrating the efficacy of commercially available non-alcohol containing mouthwashes such as Savacol (Registered Trademark), Listerine Zero (Registered Trademark) and a herbal mouthwash – Dr Organics Aloe Vera (Registered Trademark) mouthwash, in the prevention of bacterial accumulation and gum inflammation. This study is expected to give us more evidence about the benefits that these non-alcohol containing mouthwashes can provide to our patients.
