To provide subjects with positive information about endodontic treatment (ET) to reduce fear of pain associated with ET.
A large sample (n = 437) was randomly allocated to read one of five informative paragraphs and afterwards asked to complete two questionnaires (dental anxiety and fear of dental pain). The paragraphs consisted of dental information obtained from patient brochures. One (experimental) paragraph consisted of positive information about pain during ET. Analysis of variance followed by post hoc analysis was used to detect differences in mean score.
Subjects who were given the positive information regarding ET indicated they were less fearful of pain associated with ET.
The clinical implication of this experiment is that patients should be accurately informed about pain associated with ET. In this way, the patient may be more at ease before and during treatment, decrease avoidance behaviour and make decisions regarding treatment choice, based on common sense rather than fearful expectations.
向受试者提供有关牙髓治疗（ET）的积极信息，以减少与ET相关的疼痛恐惧。
将一个大样本（n = 437）随机分配，让其阅读五个信息段落中的一个，之后要求完成两份问卷（牙科焦虑和对牙科疼痛的恐惧）。这些段落包含从患者手册中获取的牙科信息。其中一个（实验性）段落包含有关ET期间疼痛的积极信息。采用方差分析及事后分析来检测平均得分的差异。
收到有关ET的积极信息的受试者表示，他们对与ET相关的疼痛的恐惧较小。
该实验的临床意义在于，应向患者准确告知与ET相关的疼痛。通过这种方式，患者在治疗前和治疗期间可能会更加放松，减少回避行为，并基于常识而非恐惧的预期做出治疗选择的决定。
