义齿口臭的相关因素研究

目的:探讨义齿口臭的的相关因素。方法:选择62例无牙周疾病且全身健康(心血管系统疾病除外)的上颌义齿修复者,鼻闻法检查口臭程度(OR值),使用便携式口气测量仪(halitosis)测量VSCs量,记录义齿使用时间、菌斑指数(plaque index,PLI)。结果:Spearman相关分析法显示口臭值与义齿使用时间、PLI存在正相关(r=0.73,r=0.52,P<0.01),义齿口臭OR值与VSCs量存在正相关(r=0.62,p<0.01),义齿使用时间与PLI也有一定的相关性(r=0.259,P<0.05)。结论:口臭值、VSCs量与聚甲基丙烯酸脂基托义齿使用时间、PLI均有关系,义齿口臭的气体成份不完全同于其它口源性口臭。

Study on the Relative Factors of Artificial Tooth Halitosis

Objective:To investigate the relative factors of artificial tooth halitosis.Methods:62 acryl denture wearing patients without periodontal disease and systematic disease(exclude cardiovascular disease)with oral malodor were included.Oral malodor was estimated by organoleptic method(organoleptic rating,OR);VSCs level was measured with a portable sulphside monitor(halimeter); used time of denture and palque index(PLI)were examined.Results:The correlation was analyzed with Spearman method.There was a significantly positive correlation between OR.VSCs levels and used time of denture and PLI,respectively(p<0.01),There was a weakely correlation between VSCs levels and PLI.Conclusion:In persent study,OR and VSCs levels were significantly correlated with uesd time of denture condition of oral hygiene(PLI),and compounds of artificial tooth halitosis are different from other oral halitosis.
