摘要:


文题释义:
牙科焦虑:指患者因牙科治疗相关刺激产生的强烈恐惧或紧张,可表现为心理担忧或生理反应。研究显示,这种焦虑易使患者延迟或回避治疗,降低依从性,进而影响口腔健康和生活质量。若不干预,可能形成“焦虑-逃避-口腔问题加重”的恶性循环。
下颌第三磨牙:俗称智齿,是位于牙列末端的磨牙,由于其特殊的解剖位置和常见的阻生情况,拔除手术常具有较大难度。该牙位牙根形态变异大,且毗邻重要神经血管,手术常需进行去骨、分牙等复杂操作,这些特点使其成为研究手术相关因素的理想模型。

背景:下颌第三磨牙拔除术患者的牙科焦虑水平显著高于其他口腔治疗,术前焦虑状态不仅可能延长手术时间,更会加重术后肿胀等不良反应。
目的:探讨术前牙科焦虑与下颌第三磨牙拔除手术时间存在的关联性。
方法:采用横断面观察性研究设计,收集航天中心医院口腔科就诊拔除下颌第三磨牙的患者216例,采用改良的第三磨牙拔除牙科焦虑量表(Dental Anxiety Scale for Third Molar Surgery,DAS-TMS)评价术前焦虑水平,记录患者的人口学特征、手术和影像学特征。主要结局指标为手术持续时间。建立多重线性回归模型分析其影响因素,采用限制性立方样条函数评价其潜在的非线性关联。
结果与结论:共有216例患者纳入研究,男性71例和女性145例;平均DAS-TMS为10.4分,其中32.4%为焦虑,8.8%为非常焦虑。在多变量调整后DAS-TMS每增加1个单位,手术时间增加1.1 min (β=1.10,P < 0.001,95%CI:0.76-1.49)。限制性立方样条函数分析观察到非线性关联的证据(非线性的P=0.013)。结果说明,术前牙科焦虑对下颌第三磨牙拔除手术时间具有显著性影响。

Abstract: BACKGROUND: Patients undergoing mandibular third molar extraction show significantly higher dental anxiety levels than those receiving other dental procedures. Preoperative anxiety not only prolongs operation time but also worsens postoperative complications.
OBJECTIVE: To investigate the relationship between preoperative dental anxiety and the time of mandibular third molar extraction. 
METHODS: A cross-sectional observational study was designed for the patient’s extraction of mandibular third molar in the outpatient clinic of Department of Stomatology of Aerospace Center Hospital. The Modified Dental Anxiety Scale for Third Molar Surgery (MDAS-TMS) was used to evaluate the preoperative anxiety status. Demographic characteristics, surgical and radiographic features of the patients were recorded. The main outcome indicator was the duration of surgery. Multivariable linear regression models were developed to analyze their influences, and a restricted cubic spline function was used to evaluate their potential nonlinear associations.
RESULTS AND CONCLUSION: A total of 216 patients (71 men and 145 women) were included in the study. The mean DAS-TMS score was 10.4, 32.4% were mildly anxious, and 8.8% were highly anxious. For each 1-unit increase in the DAS-TMS after multivariate adjustment, operative time increased by 1.1 minutes (β=1.10, P < 0.001, 95% confidence interval: 0.76-1.49). Evidence of a nonlinear association was observed (P=0.013 for nonlinearity). These findings indicate that preoperative dental anxiety has a significant effect on the time of mandibular third molar extraction procedure.
