[慢性牙周炎患者龈沟液IL-6表达与抑郁焦虑心理因素的相关分析] 牙龈炎能自愈吗

  [摘要] 目的 探寻慢性牙周炎患者龈沟液中IL-6表达与抑郁焦虑心理因素关系。 方法 选择35例慢性牙周炎(chronic periodontitis,CP)患者和34名牙周健康者。采用焦虑自评量表和抑郁症状自评量表进行问卷测评,收集龈沟液,并进行临床牙周检查,采用放射免疫法检测龈沟液中IL-6含量。 结果 对照组中IL-6总量为(0.16±0.04) ng,慢性牙周炎组为(0.28±0.02) ng。IL-6在慢性牙周炎组的表达高于对照组,P < 0.001。在IL-6与抑郁心理指数的线性回归分析中,F = 7.430,P = 0.009;在IL-6与焦虑心理指数的线性回归分析中,F = 7.150,P = 0.010。 结论 在慢性牙周炎组患者龈沟液IL-6总量升高,相对焦虑心理因素,抑郁心理因素与龈沟液IL-6总量相关性更显著。

  [Abstract] Objective To explore the relationship between the IL-6 in the gingival crevicular fluid (GCF) of the chronic periodontitis (CP) and the depression-anxiety psychological factors. Methods The CP group involved 35 patients while 34 periodontol health volunteers were enrolled as control group. The questionaires of the Self-rating anxiety scale(ASA) and the center for epidemiologic studies depression scale (CES-D) were taken, then the GCF was collected and received the clinical periodontol examination. The amount of IL-6 in the GCF was surveyed by the radio-immunoassay method. Results The amount of IL-6 in the GCF of the control group was (0.16±0.04) ng, while that of the CP was (0.28±0.02) ng. The difference between the CP and the control group was statistically significant (P < 0.001). In the linear regression equation of the IL-6 and the depressive psychological factor got F = 7.430, P = 0.009; The linear regression equation of the IL-6 and the anxiety psychological factor got F = 7.150,P = 0.010. Conclusion The chronic periodontitis get the higher amount of IL-6 of the GCF, compared with the anxiety psychological factor, the depression psychological factor get closer correlation with the IL-6 within CP.

  近年来,社会心理因素在牙周病发生发展中的作用逐渐成为研究的热点。早期研究已发现,精神心理因素是急性坏死性溃疡性牙龈炎的重要诱因[1]。Johannsen A[2]发现长期抑郁状态下的妇女有严重的牙周炎临床表现,表明慢性牙周炎与抑郁心理因素与有明显相关性。本实验通过检测慢性牙周炎患者龈沟液IL-6(interleukin-6,IL-6)的表达及其与抑郁焦虑心理因素的相关性,进一步探寻心理因素与慢性牙周炎的关系。
  1 资料与方法
  1.1 一般资料
  选择2011年5月~2011年11月在苏州大学附属第二医院口腔内科门诊就诊的中、重度牙周炎患者35例为CP组,至少有3个牙周探诊深度(PD)> 4 mm,临床附着丧失(CAL)≥ 3 mm,其中,男19例,女16例,平均年龄(42.37±7.28)岁。选择与CP组年龄和性别匹配34名牙周健康的牙体病患者(PD ≤ 3 mm,CAL = 0)作为对照组,其中,男16例,女18例,平均年龄(40.63±6.52)岁。本研究参照Armitage-1999的牙周病分类诊断标准[3]。
  两组受检者均符合以下纳入标准:(1)无系统性疾病如糖尿病、高血压等。(2)无妊娠或处于月经期女性;(3)近3个月内未接受牙周治疗,未服用抗抑郁药或心血管药,未服用过抗生素,无吸烟者。
  1.2 检测指标
  1.2.1 抑郁焦虑心理指数 在受检前以问卷方式分别对2组人员进行抑郁症状自评量表和焦虑自评量表测量。
  1.2.2 龈沟液(gingival crevicular fluid, GCF)及处理 龈沟液用消毒的吸潮纸尖收集,每6条吸潮纸尖收集1颗牙(分别位于颊侧近中、中央、远中,舌侧近中、中央、远中)的30 s龈沟液。置入250 μL磷酸盐缓冲液(PBS)中,-70℃低温冰箱保存。
  1.2.3 临床牙周检查 探诊出血指数(bleeding on probing,BOP),牙周探诊深度(probing depth,PD),临床附着丧失(clinical attachment loss,CAL)。
  1.2.4 IL-6的检测 采用放射免疫法(radio-immunoassay method,RIA)检测龈沟液中IL-6总量[4]。用系列稀释的重组人IL-6做标准曲线,IL-6的总量由标准曲线算出。
  1.3 统计学处理
  所有数据应用SPSS 15.0软件包分析。计量资料进行t检验,计数资料进行χ2检验。P
