Several correlational questionnaire studies have observed a positive relationship between psychological stress and periodontal diseases. This paper analyses the effects of academic stress on periodontal health in a prospective quasi-experimental design. 26 medical students participating in a major exam and the same number of medical students not participating in any exam throughout the study period volunteered for the study. Bleeding on probing was assessed 4 weeks prior to the exam period (baseline) and at the last day of the exam. Severe deterioration in gingival health from baseline to the last exam day were observed more frequently in exam students than in controls (p=0.014). 6 exam students but only 1 control person developed a severe gingivitis at at least one formerly healthy tooth throughout the study period. These results further support the hypothesis that psychological stress is a significant risk factor for periodontal inflammation. Future studies should examine factors mediating this relationship.
多项相关性问卷调查研究观察到心理压力与牙周疾病之间存在正相关关系。本文采用前瞻性准实验设计分析学业压力对牙周健康的影响。26名参加重要考试的医学生以及在整个研究期间未参加任何考试的同等数量医学生自愿参与了该研究。在考试期前4周（基线）和考试最后一天评估探诊出血情况。与对照组相比，考试组学生从基线到考试最后一天牙龈健康严重恶化的情况更为常见（p = 0.014）。在整个研究期间，6名考试组学生但只有1名对照组学生在至少一颗先前健康的牙齿上出现了严重牙龈炎。这些结果进一步支持了心理压力是牙周炎症重要危险因素的假设。未来的研究应考察介导这种关系的因素。
