The relationship between dental anxiety and mucosal wound healing, especially the inflammatory response, has not been well studied. This study aimed to examine the relationship between anxiety prior to dental treatment and short-term inflammation following impacted mandibular third molar (IMTM) surgery.
Fifty-nine patients who required IMTM surgery were recruited for this study. Sample demographics (gender, age) and surgical extent (Pederson classification, duration) were collected. Psychological stress towards surgery was assessed by the Dental Fear Survey (DFS). All surgeries were conducted according to an identical surgical protocol and all patients were given the same medical prescription. Correlations between short-term inflammation (swelling and trismus after 2 days) and DFS, demographics and surgical extent were statistically analysed.
The results showed that patients with a higher DFS score demonstrated more severe swelling (β = 0.36, P = 0.016) and trismus (β = 0.37, P = 0.008) 2 days after surgery. In addition, more severe trismus occurred following more difficult surgery (β = 0.29, P = 0.016) or that with a longer duration (β = 0.21, P = 0.081). Neither gender nor age showed any significant relationship with swelling or trismus.
Short-term inflammatory response following IMTM surgery correlated with the preoperative dental anxiety and this correlation was independent of gender and surgical extent.
牙科焦虑症与黏膜伤口愈合（尤其是炎症反应）之间的关系尚未得到充分研究。本研究旨在探讨牙科治疗前焦虑症与下颌第三磨牙阻生（IMTM）手术后短期炎症之间的关系。
本研究招募了 59 名需要接受 IMTM 手术的患者。收集了样本人口统计学特征（性别、年龄）和手术范围（佩德森分类、持续时间）。通过牙科恐惧调查（DFS）评估对手术的心理压力。所有手术均按照相同的手术方案进行，所有患者均给予相同的医嘱。分析了短期炎症（术后 2 天肿胀和牙关紧闭）与 DFS、人口统计学特征和手术范围之间的相关性。
结果表明，DFS 评分较高的患者术后肿胀（β=0.36，P=0.016）和牙关紧闭（β=0.37，P=0.008）更为严重。此外，手术难度较大（β=0.29，P=0.016）或手术时间较长（β=0.21，P=0.081）的患者，其牙关紧闭更为严重。性别和年龄与肿胀或牙关紧闭均无显著相关性。
IMTM 手术后的短期炎症反应与术前牙科焦虑症相关，这种相关性与性别和手术范围无关。
