Oral malodor is one of the most common complaints among dental patients. It often creates serious personal and social embarrassment for the afflicted individual. Therefore, a dentist must be able to diagnose the etiology of halitosis and treat it or refer an individual to a specialist. The aim of this study was to evaluate the prevalence of halitosis and the effect of a peppermint mouth rinse on it.
This study was performed in two steps. At the first step, in a cross-sectional study, 504 students who were 14-18 years old were examined to define the students who suffered from halitosis, and then at the second step, the selected 84 students with halitosis were divided into two groups randomly. A total of 43 students in group 1 received a peppermint mouth rinse and 41 students in another group were given placebo. The students in two groups washed their mouth with 15-20 ml of the given solutions three times in a 1-week period (after breakfast, after lunch or on returning to home, before sleeping) and didn't eat anything for 30 min after rinsing. After 1 week, the students were examined again.
The prevalence of halitosis was 24.4% totally. In the mouth rinse group, after 1 week 23 students didn't exhibit halitosis, and 11 students in the placebo group were halitosis positive. A chi-square test showed that this difference was significant.
Based on the results of this study, it can be said that a peppermint mouth rinse can reduce halitosis.
口腔异味是牙科患者最常见的主诉之一。它常常给患者带来严重的个人和社交尴尬。因此，牙医必须能够诊断口臭的病因并进行治疗，或将患者转介给专科医生。本研究的目的是评估口臭的患病率以及薄荷漱口水对其的影响。
本研究分两步进行。第一步，在一项横断面研究中，对504名14 - 18岁的学生进行检查，以确定患有口臭的学生，然后在第二步，将选定的84名口臭学生随机分为两组。第1组共有43名学生接受薄荷漱口水，另一组41名学生接受安慰剂。两组学生在1周内（早餐后、午餐后或回家后、睡觉前）用15 - 20毫升给定溶液漱口三次，漱口后30分钟内不吃任何东西。1周后，再次对学生进行检查。
口臭的总体患病率为24.4%。在漱口水组，1周后23名学生没有口臭，安慰剂组有11名学生口臭呈阳性。卡方检验表明这种差异具有显著性。
基于本研究结果，可以说薄荷漱口水可以减少口臭。
