不同程度牙周炎患者龋病情况初步分析?

目的：探讨牙周炎患者与牙周正常者龋病情况的差别。方法通过曲面断层片、牙周探诊和问卷调查2014年1月至2015年6月到山东省千佛山医院口腔科就诊的456例患者(包括牙周正常140例,轻度牙周炎104例,中度牙周炎98例,重度牙周炎114例),检查龋失补数、口腔卫生情况及生活习惯。应用SPSS19.0软件对调查结果进行统计学分析。结果牙周正常组、轻度牙周炎组、中度牙周炎组和重度牙周炎组龋补牙面数分别为(1.44±1.02)面、(1.82±0.91)面、(2.36±1.94)面和(2.89±2.42)面,牙周炎组龋补牙面数较高,与牙周正常组比较差异均有统计学意义(P<0.05);重度牙周炎组失牙数为（1.58±1.54）个,高于牙周正常组的(0.65±0.35)个,差异有统计学意义(P<0.05);牙周炎组的简易牙石指数(CI-S)[(0.99±0.74)、(1.69±0.63)、(2.08±0.50)]、简易出血指数(SBI-S)[(1.21±1.05)、(1.87±1.74)、(2.56±1.09)]与牙周正常者的CI-S (0.60±0.32)、SBI-S (0.74±0.47)相比差异均有统计学意义(P<0.05),牙周正常者简易菌斑指数(DI-S)(0.67±0.52)要低于中度、重度牙周炎组[(1.59±1.05)、(1.87±0.77)],但与轻度牙周炎组(0.87±0.73)比较差异均无统计学意义(P>0.05);饮茶者的龋病发病率低于不饮茶者(P<0.05）,而抽烟者的龋齿发病率也低于不抽烟者(P<0.05)。结论牙周炎患者龋失补数高于牙周正常者,口腔卫生情况也比牙周正常者差,饮茶、抽烟也影响着龋病的发生。

Preliminary analysis of dental caries situation in patients with varying degrees of periodontitis

Objective To investigate the dental caries situation in patients with periodontitis and subjects with-out periodontitis. Methods A total of 456 patients in the Department of Stomatology in Qianfoshan Hospital of Shan-dong from January 2014 to June 2015 were enrolled in the study, including 140 with normal periodontal, 104 with mild periodontitis, 98 with moderate periodontitis, and 114 with severe periodontitis. The decayed-missing-filled teeth (DMFT), oral hygiene and living habits were examined by using panoramic radiographs, periodontal probing and ques-tionnaires. SPSS19.0 software was applied for statistical analysis. Results The number of decayed-filled teeth surfaces of the normal periodontal group, mild periodontitis group, moderate periodontitis group and severe periodontitis group were (1.44±1.02), (1.82±0.91), (2.36±1.94) and (2.89±2.42), with statistically significant difference between the normal periodontal group and the periodontitis groups (P<0.05). The number of missing teeth due to caries in severe periodonti-tis group [(1.58±1.54)] was higher than that in normal periodontal group [(0.65±0.35)], and the difference was statistically sig-nificant (P<0.05). In the three periodontitis groups, the simple calculus index (CI-S) [(0.99±0.74), (1.69±0.63), (2.08±0.50)], sulcus bleeding index (SBI-S) [(1.21±1.05), (1.87±1.74), (2.56±1.09)] showed statistically significant difference with those in normal periodontal group [CI-S (0.60 ± 0.32), SBI-S (0.74 ± 0.47)], P<0.05. The simple plaque index (DI-S) in normal peri-odontal group [(0.67±0.52)] was significantly lower than that of moderate periodontitis group [(1.59±1.05)] and severe peri-odontitis group [(1.87 ± 0.77)], but showed no statistically significant difference with that of mild periodontitis group [(0.87 ± 0.73)], P>0.05. The incidence of caries in tea drinkers was significantly lower than that of non-drinkers (P<0.05), and the inci-dence in smokers was also significantly lower than non-smokers (P<0.05). Conclusion In patients with periodontitis, the number of DMFT is higher than that of periodontal healthy patients, and oral hygiene is worse than that of periodontal healthy patients. Drinking tea and smoking affects the incidence of dental caries.
