effect of halita mouthwash on oral halitosis treatment: a randomized triple-blind clinical trial

Background. halitosis (oral malodor) is a common problem all over the world and its prevalence has been estimated at 23‒50%. halitosis originates from oral cavity in 85% of patients. this clinical trial was conducted to evaluate the efficacy of the halita mouthwash in oral halitosis treatment. methods. fifty subjects with an organoleptic score of >2 at baseline participated in this triple-blinded clinical trial. subjects were divided into 2 groups. group i subjects (n=25) were instructed to rinse with 0.2% chlorhexidine (chx) mouthwash twice a day for 1 week. group ii subjects (n=25) used halita mouthwash with the same instruction. halitosis was evaluated at baseline and one week after using the mouthwashes by organoleptic method. data were analyzed with chi-squared and mann-whitney u tests (p<0.05). results. in the halita group subjects exhibited 2.04±0.65 reduction in ols. ols reduction in the chlorhexidine group was 1.95±0.74. statistical analysis showed no significant difference between the two groups (p>0.05). conclusion. based on the results, halita mouthwash has the same effect on oral halitosis as routine 0.2% chx mouthwash. halita mouthwash has fewer side effects because of lower concentration of chlorhexidine. therefore 0.2% chx mouthwash could be replaced by halita mouthwash for the treatment of halitosis.
