目的：探讨 A型人格行为对慢性牙周炎发生发展的影响，比较不同类型人格行为人在慢性牙周病发生发展过程中的差异，阐明心理社会因素对慢性牙周炎发病的影响。方法：选取于门诊就诊的慢性牙周炎患者132例（牙周炎组）和牙周健康患者126例（牙周健康组）。牙周炎诊断标准采用世界卫生组织1987版“Oral Surveys Basic Methods”以及美国牙周病学会（AAP）2000年制订的牙周病诊治参照标准。指导受试者填写A型人格行为类型问卷（1983年张伯源标准，1985年修订版）及 SCL-90症状自评量表。分别记录受试者各项得分，各独立变量采用t检验进行分析。结果：相比于 M型和B型人格，A型人格行为者在牙周炎组（68.94％）所占比例明显高于牙周健康组（27.78％）（P＜0.05）；且牙周炎组患者敌对（1.54±0.38）、焦虑（1.47±0.39）、抑郁（1.41±0.37）、人际关系敏感（1.23±0.39）、强迫症状（1.72±0.46）和躯体化（1.47±0.38）等项目得分明显高于牙周健康组（1.32±0.30、1.29±0.24、1.25±0.23、1.04±0.17、1.41±0.35、1.25±0.24）（P＜0.05），且该类人群牙石指数（CI）高于其他人群（P＜0.05），并更需要牙周治疗。结论：A型人格行为比其他人格类型更易罹患慢性牙周炎。%Objective:To investigate the influence of type A behavior in the occurrence and development of chromic periodontitis and compare the differences among people with different behavior types in the occurrence and development of chronic periodontitis, and to explore the influence of psychological factors in the process of periodontitis.Methods:According the same standard,132 patients with periodontitis were selected as periodontitis group,and 126 patients without periodontitis were used as control group.OralSurveys Basic Methods proposed by WHO in 1987 and ReferenceStandard of Diagnosis and Treatment of Periodontitis made by AAP in 2000 were used to dignose the periodontitis.All subjects finished type A behavior and SCL-90 questionnaire (ZHANG Boyuan 1983,revision in 1985 ), their scores were recorded and the results were analyzed by t test. Results:The proportion of type A behavior in periodontits group (68.94%)was higher than that in control group (27.78%) (P<0.05)compared with type M and type B behavior.The scores of hostility (1.54±0.38),anxiety (1.47± 0.39),depression (1.41 ± 0.37),interpersonal sensitivity (1.23 ± 0.39),compulsive (1.72 ± 0.46),and somatizition (1.47 ± 0.38)were significantly higher than those in control group (1.32 ± 0.30, 1.29 ± 0.24, 1.25±0.23,1.04± 0.17,1.41 ± 0.35,1.25 ± 0.24).The calculus index (CI)of the people with type A behavior was higher than those of the people with other types of behavior (P<0.05).Conclusion:The people with tyep A behawior is easier to get periodontitis than other people.
