1、硕士学位论文吸烟对牙周炎基础治疗前后龈沟液中C反应蛋白水平的影响 The impact of smoking on C-reactive protein levels in the gingival crevicular fluid before and after initial treatment in periodontitis 作者姓名: 专 业:口腔临床医学研究方向:牙周病学 指导教师: 培养单位:口腔医学院中文摘要吸烟对牙周炎基础治疗前后龈沟液中C反应蛋白水平的影响牙周炎是由多种牙周致病菌引起的牙周支持组织慢性感染性疾病,定居在牙颈部及龈沟内的牙菌斑微生物为其主要的感染源。尽管牙菌
2、斑为牙周病的始动因素,但其单独存在并不一定能引起牙周病。吸烟是人类许多疾病的一个重要危险因素,许多横向和纵向研究均证实,吸烟是牙周炎尤其是重度牙周炎的高危因素。龈沟液中含有来源于细菌和人体组织的多种成分,龈沟液的量及其成分的变化可作为评估牙周炎临床症状和预后的指标。C反应蛋白(C-reactive protein,CRP)作为一种急性期反应蛋白,其在致炎过程中发挥着关键作用。因此,近年来CRP越来越受到学者们的关注。目的:1. 通过比较牙周基础治疗前,吸烟与非吸烟中重度牙周炎患者PLI、BI、PD、AL,以探讨吸烟对牙周组织破坏程度的影响;2. 通过测定牙周基础治疗前GCF的量和GCF中CRP
3、的水平,以探讨吸烟对牙周炎症状态下GCF量和其中CRP浓度的影响;3. 通过进一步比较牙周基础治疗前后吸烟与非吸烟中重度牙周炎患者PLI、BI、PD、AL以及GCF量和其中CRP浓度的变化,以探讨牙周基础治疗对吸烟和非吸烟中重度牙周炎患者的治疗效果,以及吸烟对牙周炎基础治疗效果的影响。方法:1. 病例选择:随机选取2011年3月至2011年10月就诊于吉林大学口腔医院牙周病科,被诊断为中重度牙周炎,年龄、性别相匹配的吸烟者和非吸烟患者各18例。2. 样本的采集和保存:利用吸潮纸尖采集牙周基础治疗前和基础治疗后4周受试牙的龈沟液于Eppendorf管中,并用电子天平称重后,-70冷冻保存,待检。
4、3. 临床指标的检查和记录:检查并记录牙周基础治疗前和基础治疗后4周的临床指标。其中,以Silness&Le菌斑指数,判断受试者治疗前后菌斑堆积的量;利用Mazza龈沟出血指数记分方法,观察治疗前后牙龈出血程度的变化。同时按照牙周病学(第3版)的标准,检测受试者治疗前后PD、AL的变化。4. 龈沟液中CRP的检测:利用CRP放射免疫试剂盒,采用放射免疫平衡法测定受试牙龈沟液中CRP的含量。5. 统计学分析:利用统计学软件包SPSS13.0对实验中所得数据进行统计学分析。结果:1. 在牙周基础治疗前,吸烟组PLI、PD以及AL明显高于非吸烟组;吸烟组BI低于非吸烟组。牙周基础治疗后4周,吸烟组和
5、非吸烟组PLI、BI、PD、AL均较治疗前明显降低。2. 在牙周基础治疗前,吸烟组GCF的量及其中CRP的浓度明显高于非吸烟组。牙周在基础治疗后4周,吸烟组与非吸烟组GCF的量及其中CRP的浓度较治疗前明显降低。3. 牙周炎吸烟组和牙周炎非吸烟组牙周基础治疗前后,临床指标(PLI、BI、PD、AL)的改善程度和GCF量及其中CRP浓度的变化存在着显著的不同。牙周炎吸烟组除了PLI变化较非吸烟组明显外,其他临床指标(BI、PD、AL)以及GCF量和其中CRP浓度的变化均明显低于非吸烟组。结论:1. 在牙周基础治疗前,牙周炎吸烟组PLI、PD以及AL明显高于牙周炎非吸烟组。结果表明:吸烟者菌斑堆积
6、量大于非吸烟者,牙周组织破坏程度也较非吸烟者严重。2. 在牙周基础治疗前,牙周炎吸烟组GCF的量以及GCF中CRP的浓度明显高于牙周炎非吸烟组。结果表明:吸烟牙周炎患者牙周炎症程度重于非吸烟牙周炎患者,这种炎症的加重与GCF中的CRP有关。3. 在牙周基础治疗后4周,吸烟组和非吸烟组PLI、BI、PD、AL、GCF的量以及GCF中CRP的浓度均较治疗前明显降低,但吸烟组降低的量小于非吸烟组。结果表明:无论是吸烟者,还是非吸烟者,牙周基础治疗均可明显改善其炎症状况;吸烟可能是牙周炎基础治疗的不利因素。关键词:吸烟,牙周炎,基础治疗,龈沟液, C反应蛋白AbstractThe impact of
7、smoking on C-reactive protein levels in the gingival crevicular fluid before and after initial treatment in periodontitisPeriodontitis is a chronic infection in periodontal support tissue caused by a variety of risk factors, chiefly when plaque micro-organisms settle in the cervical and gingival sul
8、cus. Although plaque is a periodontal disease initiating factor, the presence of plaque does not necessarily cause periodontal disease. Smoking is an major cause of many human diseases, and several lateral and longitudinal studies have confirmed that smoking is a risk factors for periodontitis, in p
9、articular for severe periodontitis. Gingival crevicular fluid contains a variety of ingredients derived from bacteria and human tissue. The amount of gingival crevicular fluid and the changes in its composition can be used as indicators to judge periodontitis clinical symptoms and prognosis. CRP, as
10、 an acute phase response proteins, plays a key role in the proinflammatory process. Therefore, CRP is drawing more and more scholars attention in recent years.Objective:1. Explore the impact of smoking on periodontal tissue destruction, by comparing of the PLI, BI, PD, AL of smoking and non-smoking
11、periodontitis patients before initial treatment.2. Explore the impact of smoking on GCF volume and CRP concentration in GCF in the periodontal disease status, by detecting the GCF volume and CRP levels in GCF before initial treatment.3. Explore the effect of periodontal initial treatment on smoking
12、and non-smoking periodontitis patients, and the effect of smoking on periodontal initial treatment, by comparing of the PLI, BI, PD, AL, GCF volume and CRP concentration in GCF of smoking and non-smoking periodontitis patients before and after initial treatment.Methods:1. Choice of cases: Randomly s
13、elected age, sex matched smokers and non-smokers 18 cases, treated in Stomatology Hospital of Jilin University in March 2011 to October 2011 and diagnosed with severe periodontitis.2. Sample collection and preservation: obtain gingival crevicular fluid by using absorbent paper point, and weigh with
14、an electronic balance. Store the gingival crevicular fluid in a -70 C temperature refrigerator.3. Inspect and record the clinical indicators: determine the amount of subjects plaque accumulation by using Silness & Le plaque index; observe the degree of bleeding gums by using Mazza sulcus bleeding in
15、dex scoring method; At the same time, detect subjects PD, AL in accordance with the standard of Periodontology (3rd edition).4. Detect CRP concentration in GCF: radioimmunoassay balance method will be used to determine CRP levels in the samples.5. Statistical analysis: All data obtained from the exp
16、eriment were analyzed by the Statistical Package SPSS13.0.Results:1. Before the initial periodontal therapy, the PLI, PD and AL of the smoking group were significantly higher than non-smoking group, while the smoking groups BI was lower than non-smoking group. After initial periodontal therapy over
17、4 weeks, the PLI, BI, PD, AL of the smoking and non-smoking groups were significantly reduced compared with pre-treatment.2. Before the initial periodontal therapy, GCF volume and CRP concentration in GCF of the smoking group was significantly higher than the non-smoking group. After initial periodo
18、ntal therapy 4 weeks, GCF volume and CRP concentration in GCF of the smoking group and non-smoking group were significantly lower than before treatment.3. Before and after the initial treatment, there were significantly differences in the changes of PLI, BI, PD, AL, GCF volume and CRP concentration
19、in GCF of the smoking and non-smoking periodontitis patients. The PLI change of the smoking group was more significant than that of the non-smoking group, but the changes of other clinical indicators were less significant than those for the non-smoking group.Conclusion:1. The amount of plaque accumu
20、lation in smokers is greater than non-smokers and the smokers periodontal tissue destruction was more serious than non-smokers. 2. The degree of periodontal disease of smokers are more serious than non-smokers, and that is related with CRP concentration in GCF.3. The initial periodontal therapy coul
