牙周门诊患者口臭的自我评价及影响因素的分析

Study on self-reported halitosis and the associated factors in patients in a periodontal clinic

目的:了解牙周门诊患者的口臭自我评价情况,并分析影响因素。方法:选取接受过口臭检测且不吸烟的患者435名,进行口气检测与问卷调查,其中312人接受了舌苔检查。结果:435名受检者中,273人认为自己有口臭,将这273名主诉口臭患者按实际检测的有、无分为真性口臭组(188人,68.8%)与假性口臭组(85人,31.2%)。假性口臭组中不愿意提及口臭的患者比例高于真性口臭组,两组间差异有统计学意义(P=0.003)。假性口臭组中接受过口臭治疗的患者比例高于真性口臭组,差异具有统计学意义(P=0.029)。多因素分析表明,刷牙出血(OR=2.905,P<0.001)、舌苔面积≥2(OR=2.395,P=0.019)、舌苔厚度≥2(OR=3.419,P<0.001)的患者更容易产生口臭。结论:并非所有主诉口臭的患者均为真性口臭,假性口臭患者心理状态与真性口臭患者不同;刷牙出血、舌苔面积大、舌苔厚度厚的患者更容易产生真性口臭。

Objective：To evaluate self-reported halitosis in patients who visited a periodontal clinic and assess the possible factors associated with genuine halitosis.Methods： The subjects included 435 patients who visited periodontal department of Peking University,School and Hospital of Stomatology.All of them were non-smokers.First,the degree of halitosis was estimated by Organoleptic Test.Then,a stan-dardized questionnaire focusing on life style,oral hygiene,medical history,dental condition,self-reported halitosis was completed by all participants.Additionally,tongue coating was evaluated for 312 patients.Results： 273 of 435 participants had self-reported halitosis.According to Organoleptic Test,31.2% patients complaining halitosis had actually no malodor while 68.8% had genuine halitosis.There was statistically significant difference of the proportion of patients who were unwilling to mention about halitosis between genuine halitosis group and pseudo-halitosis group（P=0.003）.Proportion of patients who had accepted treatment for halitosis was statistically significant higher in pseudo-halitosis group than in genuine halitosis group（P=0.029）.Logistic regression analysis showed bleeding on brushing（OR=2.905,P=0.000）,area of tongue coating≥2（OR=2.395,P=0.019）,thickness of tongue coating≥2（OR=3.419,P=0.000） were factors associated with genuine halitosis.Conclusion： Not all self-reported patients actually had malodor,the psychological condition was different between pseudo-halitosis and genuine halitosis patients.Bleeding on brushing,large tongue coating area,thick tongue coating were associated with genuine halitosis.
