Subjects served as their own control when tooth pulp shock was delivered in laboratory and clinical situations. Significantly heightened pain was observed in the clinical dental setting. The dental setting proved more anxiety-provoking and associated with reduced tolerance for pain, suggesting that cognitive contexts of a dental setting may elicit heightened subjective pain responses.
在实验室和临床环境中进行牙髓冲击时，受试者以自身作为对照。在临床牙科环境中观察到疼痛明显加剧。牙科环境被证明更易引发焦虑，且与疼痛耐受性降低有关，这表明牙科环境的认知背景可能会引发更强的主观疼痛反应。
