Protocol summary

Summary
Aim: The use of Chlorhexidine is strongly recommended in prevention and treatment of periodontal diseases. This product unfortunately has some side effects such as extrinsic tooth staining and taste disturbance. The aim of this clinical trial is comparison of the tooth staining, taste disturbance and antibacterial effect of 0.2% with 0.12% Chlorhexidine mouthrinses. If the low dose mouthwash shows the same antibacterial effect as the higher dose with lesser side effects, it can be an appropriate substitute. Study Design: Interventional, randomized, double blind, unicenter, no placebo, cross over clinical trial. Inclusion Criteria: Patients with gingivitis or mild periodontitis. Exclusion criteria: Hypersensitivity to mouthwashes, pregnancy, nursing Period. All subjects received a complete dental prophylaxis before using either mouthwash.

After one week of wash out period the subjects entered the second 7 days period using the other product in the same manner. After each period, discoloration index and taste disturbance were measured. Also before and after mouthwash application, microbial plaque was obtained to microbial culture. Sample Size: Fifty-two interventions in 26 patients(18-60) without sex limitation Intervention: Utilization of mouthwashes

Other design features
Randomization: This study had two 7days periods. During these periods the subjects used one of the mouthwashes randomly. There was a wash out period between these two periods. Randomization carried out by throwing the coin in which 26 patients divided randomly to two groups each including 13 patients. The patients of one group used the 0.2% Chlorhexidine mouthwash during the first period and the patients of the second group used the 0.12% Chlorhexidine mouthwash during the first period. Blindness: this study was double blind because the mouthwashes were given to the patients in uniform bottles by another person other than the investigator. At the end of the study he was asked to mention the set up for application of these mouthwashes by the patients.
