The purpose of this study is to compare the efficacy of two chlorhexidine and Halita mouthrinses in reducing bad breath in patients referring to the Department of Oral Medicine at Tabriz University of Medical Sciences.
Inclusion criteria: Organoleptic score (OLS) of over 2.
Exclusion criteria: Alcohol and tobacco use; Systemic diseases; Medications that cause dry mouth; Consumption of antibiotics in the previous two weeks; Pocket depth greater than 6 mm; Eating spicy foods, onion, and garlic 48 hours prior to the examination; Use of orthodontic appliances (fixed or removable) and removable dental prosthesis; Allergy or any undesirable reactions to either of test mouthrinses.
It should be noted that, during the study period, the participants did not receive dental procedures such as scaling, restoration, etc. and thus their oral health conditions were unchanged.
The most important issue in treatment of bad breath is to identify the cause in order to eliminate it. An easy and low-cost way is to administer health protocols that involve the use of toothbrush, dental floss, and mouthwash. Chemical methods such as using mouthwashes are complement to mechanical methods. A large number of studies on different types of mouthwashes such as chlorhexidine, cetylpyridinium chloride, and zinc have been performed. 50 samples were randomly selected and divided into two groups of 25, with consideration for the drop-out in the current triple-blind randomized controlled clinical trial. Halita (containing 0.05% chlorhexidine, 0.05% cetylpyridinium chloride, and zinc) and chlorhexidine moutrinses (both provided by Rozhin Co., Tabriz, Iran) were prepared in 140 ml volume for 7-day use (14 doses) in blindly marked similar containers. Oral and written instructions of using the mouthrinse were given to the patients. After 7 days, patients in both groups were examined to evaluate the effects.
