Abstract：
The FDI is currently working on developing a tool to encompass patient-reported outcome measures (PROMs) within the overall assessment of outcomes of endodontic treatment. The outcome of endodontic treatment has traditionally been determined by various clinical and radiographic criteria. However, these parameters do not address the impact of treatment on a patient\'s oral health-related quality of life (OHRQoL). OHRQoL, a crucial PROM, can be used to understand treatment outcome from a patient-centred perspective, thus improving clinician-patient communication whilst guiding decision-making. This focussed review aims to recount the OHRQoL of patients following nonsurgical root canal treatment and surgical endodontic treatment, with a specific focus on the minimal important difference (MID; the minimum score changes of an outcome instrument for a patient to register a clinically significant change in their OHRQoL and/or oral condition) and the methods used to determine it. The current evidence indicates that the OHRQoL of patients requiring root canal treatment is poorer than those without such need. Accordingly, the literature suggests that OHRQoL improves following nonsurgical or surgical endodontic treatment. However, study methodologies vary widely, and conclusions cannot be drawn with high confidence, nor can MID recommendations be provided. Well-designed clinical studies with baseline measurements and appropriate follow-up time frames are therefore needed. Despite that the literature is rife with outcome studies, research on PROMs is an area that deserves greater attention, particularly in relation to the MID. Determining the MID will facilitate the understanding of changes in outcome scores from the patients\' perspective, thus allowing for more informed decision-making in clinical practice.
摘要：
FDI目前正在开发一种工具，将患者报告的结果指标（PROM）纳入牙髓治疗结果的总体评估中。传统上，牙髓治疗的结果由各种临床和放射学标准确定。然而,这些参数不能说明治疗对患者口腔健康相关生活质量(OHRQoL)的影响.OHRQoL,一个至关重要的舞会，可用于从以患者为中心的角度理解治疗结果，从而改善临床医生与患者的沟通，同时指导决策。这项重点综述旨在回顾非手术根管治疗和手术牙髓治疗后患者的OHRQoL，特别关注最小的重要差异（MID；患者记录其OHRQoL和/或口腔状况的临床显着变化的结果工具的最低评分变化）以及用于确定该差异的方法。目前的证据表明，需要根管治疗的患者的OHRQoL比没有这种需要的患者差。因此，文献提示OHRQoL在非手术或手术牙髓治疗后改善.然而,研究方法差异很大，不能高度自信地得出结论，也不能提供MID建议。因此，需要精心设计的具有基线测量和适当随访时间框架的临床研究。尽管文献中充斥着结果研究，对PROM的研究是一个值得更多关注的领域，特别是与MID有关。确定MID将有助于从患者的角度理解结果评分的变化，从而允许在临床实践中做出更明智的决策。
