Objectives : This study was designed to investigate the difference between genuine and pseudo halitosis about qi stagnation and stress. Methods : We recruited 63 halitosis patients who visited the halitosis clinic in the Kyung Hee University Korean Medicine Hospital from June 2012 to August 2013. We classified the halitosis patients into two groups, genuine and pseudo halitosis based on organoleptic assesment (OLT) score and evaluated the severity of self-reported halitosis using visual analog scale (VAS), amount of sulfide compounds using Halimeter, qi stagnation level using qi stagnation questionnaire and stress levels using heart rate variability (HRV) parameters. Results : Comparing the genuine halitosis group and the pseudo halitosis group, there was no significant difference in VAS of halitosis but significant difference in halimeter score. Distribution of qi stagnation and non-qi stagnation groups was significantly different between genuine and pseudo halitosis. Compared to the genuine halitosis group, the pseudo halitosis group showed a significant higher value of low frequency/high frequency ratio (LF/HF ratio). Conclusions : The result of this study suggest that there is significant difference about qi stagnation and stress level between genuine halitosis and pseudo halitosis patients, so when approaching pseudo halitosis patients, we should consider their psychological and emotional status.

Objectives: This study was designed to investigate the difference between genuine and pseudo-halitosis in terms of clinical characteristics. Methods: We recruited 51 halitosis patients who visited the halitosis clinic at Kyung Hee University Korean Medicine Hospital from March 2020 to March 2022. We classified the halitosis patients into two groups, genuine and pseudo halitosis, based on oral chroma and evaluated the status of hyposalivation using the drainage method, stress levels using heart rate variability (HRV) parameters, and Ryodoraku. Results: Comparing the genuine halitosis group and the pseudo halitosis group, there was no significant difference in the status of hyposalivation and HRV parameters. However, Ryodoraku was significantly different between genuine and pseudo halitosis. Compared to the genuine halitosis group, the pseudo halitosis group showed a significantly higher value of total average (TA) of Ryodoraku. Conclusion: The results of this study suggest that there is a significant difference in Ryodoraku between genuine halitosis and pseudo halitosis, so when approaching pseudo halitosis patients, we should consider their excitability of the sympathetic nervous system and metabolic function status.

Purpose: This study was designed to evaluate the sex and age differences in the Korean oral malodor patients. Methods: Subjects were the patients with oral malodor (male, 2,239; female, 3,496) visited the Department of Oral Medicine, Kyung Hee University Dental Hospital from January 2007 to December 2012 were recruited to this study and measured the volatile sulfur compounds (VSCs) in the oral cavity with Halimeter. Results: There were slightly more female than male (female : male=3 : 2), and the mean values of Halimeter result were 65.79 ppb (female) and 79.94 ppb (male), which was more higher in male. Total patients showed normal age distribution in both gender, and the peak was the age of 26-35 in female, the age of 36-45 in male. The percentages of pseudo-halitosis were 74.7% in female and 69.3% in male, which was more higher in female. Conclusions: Therefore, it was revealed that women are more likely to have oral malodor than men, and there was a difference in the largest age group between men and women. Also women had more pseudo-halitosis patient than men.
