Oral health-related quality of life (OHRQoL) is expected to be multidimensional. However, it is unknown what these dimensions are. This study aimed to explore the dimensional structure of OHRQoL using experts' opinions. A conceptual model of oral health with seven dimensions (functional limitation; physical pain; psychological discomfort; physical, psychological, social disability; handicap) was provided to 14 health care professionals. They assigned each of 49 items of an OHRQoL questionnaire, the Oral Health Impact Profile (OHIP), to the seven model dimensions. All 49 items could be assigned to one or more dimensions of OHRQoL. All seven dimensions of the conceptual model of oral health were identified: Functional limitation appeared 14 times, physical pain eight times, psychological discomfort 12 times, physical disability once, psychological disability four times, social disability nine times, and handicap once. This supported a seven-dimensional model of OHRQoL. However, when items were grouped into clusters with unique content, a smaller model appeared with the dimensions oral functions, orofacial pain, psychological impact, and social impact.
口腔健康相关生活质量（OHRQoL）预计具有多维度性。然而，这些维度具体是什么尚不清楚。本研究旨在利用专家意见探索OHRQoL的维度结构。一个包含七个维度（功能受限；身体疼痛；心理不适；身体、心理、社会残疾；障碍）的口腔健康概念模型被提供给14名医疗保健专业人员。他们将一份OHRQoL问卷（口腔健康影响程度量表，OHIP）中的49个项目分别归入七个模型维度。所有49个项目都可以被归入OHRQoL的一个或多个维度。口腔健康概念模型的所有七个维度都被识别出来：功能受限出现14次，身体疼痛出现8次，心理不适出现12次，身体残疾出现1次，心理残疾出现4次，社会残疾出现9次，障碍出现1次。这支持了OHRQoL的七维度模型。然而，当项目被分组为具有独特内容的集群时，出现了一个较小的模型，其维度包括口腔功能、口面部疼痛、心理影响和社会影响。
