The aims were to evaluate the validity of patients' self-estimation and clinical diagnosis of oral malodor and to examine the relationship of oral malodor with oral health status.
The subjects were 252 patients (mean age 43.7 ± 10.7 years) who complained of oral malodor. Oral malodor was assessed by patients' self-estimation, organoleptic test and Oral Chroma. Oral health status, including dental and periodontal conditions, oral hygiene status and flow rate of saliva, was examined. The N-benzoyl-DL-arginine-2-napthilamide (BANA) positive bacteria in tongue coating were evaluated by BANA test. A Spearman's correlation coefficient was used to test correlation between self-perceived and clinical oral malodor. The stepwise multiple regression analysis was used to assess predictors of patients' self-estimated and clinical oral malodor.
The percentage of patients who were diagnosed with pseudo-halitosis was 38.5%. Patients' self-estimated oral malodor was significantly correlated with organoleptic test (r = 0.61), H(2)S (r = 0.50) and CH(3)SH (r = 0.46). There were 47.1% of patients who estimated correctly their oral malodor's scores with those by examiner. The highest correspondence was found in patients without oral malodor (52.6%), followed by in those with moderate or strong oral malodor (46.7%) and in those with slight oral malodor (33.3%). The significant predictors of patients' self-estimated and clinical oral malodor were bleeding on probing, tongue coating, BANA test and flow rate of saliva.
Patients' self-estimated oral malodor was found to correspond significantly with clinical oral malodor and be associated with oral health status. Current findings suggest that self-estimation can be used to judge one's own oral malodor.
评估患者自我评估和临床诊断口臭的有效性，并研究口臭与口腔健康状况的关系。
共纳入 252 名有口臭主诉的患者（平均年龄 43.7 ± 10.7 岁）。患者自我评估、嗅诊和口气仪检测结果用于评估口臭，同时还检查了口腔健康状况（包括牙齿和牙周状况、口腔卫生状况和唾液流速）。采用 N-苯甲酰-DL-精氨酸-2-萘酰胺（BANA）试验评估舌背的 BANA 阳性菌。采用 Spearman 相关系数检验患者自我感知和临床口臭之间的相关性。采用逐步多元回归分析评估患者自我评估和临床口臭的预测因素。
38.5%的患者被诊断为假性口臭。患者自我评估的口臭与嗅诊（r = 0.61）、H₂S（r = 0.50）和 CH₃SH（r = 0.46）显著相关。47.1%的患者能够正确估计自己的口臭评分。在无口臭的患者中相关性最高（52.6%），其次是中重度口臭患者（46.7%）和轻度口臭患者（33.3%）。患者自我评估和临床口臭的显著预测因素为探诊出血、舌背附着物、BANA 试验和唾液流速。
患者自我评估的口臭与临床口臭显著相关，与口腔健康状况有关。这些发现提示自我评估可以用于判断个体的口臭。
