Abstract

While pain chronicity in general has been defined as pain lasting for more than 3 months, this definition is not useful in orofacial pain (OFP) and headache (HA). Instead, chronicity in OFP and HA is defined as pain occurring on more than 15 days per month and lasting for more than 4 h daily for at least the last 3 months. This definition excludes the periodic shortlasting pains that often recur in the face and head, but are not essentially chronic. Although the headache field has adopted this definition, chronic orofacial pain is still poorly defined. In this article, we discuss current thinking of chronicity in pain and examine the term 'chronic orofacial pain' (COFP). We discuss the entities that make up COFP and analyze the term's usefulness in clinical practice and epidemiology.

慢性口面部疼痛。

摘要

虽然通常将疼痛慢性定义为持续超过3个月的疼痛，但该定义不适用于口面部疼痛（OFP）和头痛（HA）。相反，OFP和HA的慢性被定义为每月至少15天发生疼痛，至少在最近3个月内每天持续4小时以上。该定义排除了经常在面部和头部复发但基本上不是慢性的周期性持续性疼痛。尽管头痛领域已经采用了这种定义，但是慢性口面部疼痛的定义仍然不明确。在本文中，我们讨论了疼痛慢性病的当前思想，并研究了术语“慢性口面部疼痛”（COFP）。我们讨论组成COFP的实体，并分析该术语在临床实践和流行病学中的有用性。
