Direct posterior dental restorations are commonly provided following management of dental caries. Amalgam use has been phased down and the feasibility of a phase-out by 2030 is being explored. Alternative direct restorative materials differ in their outcomes and provision. This research aimed to elicit the UK population’s preferences for different attributes of restorations and their willingness to pay (WTP) for restorative services and outcomes. A discrete choice experiment (DCE) was designed with patient and public involvement and distributed to a representative sample of the UK general population using an online survey. Respondents answered 17 choice tasks between pairs of scenarios that varied in levels of 7 attributes (wait for filling, clinician type, filling color, length of procedure, likely discomfort after filling, average life span of filling, and cost). An opt-out (no treatment) was included. Mixed logit models were used for data analysis. Marginal WTP for attribute levels and relative attribute importance were calculated. In total, 1,002 respondents completed the DCE. Overall, respondents were willing to pay £39.52 to reduce a 6-wk wait for treatment to 2 wk, £13.55 to have treatment by a dentist rather than a therapist, £41.66 to change filling color from silvery/gray to white, £0.27 per minute of reduced treatment time, £116.52 to move from persistent to no postoperative pain, and £5.44 per year of increased restoration longevity. Ability to pay affected willingness to pay, with low-income respondents more likely to opt out of treatment and value restoration color (white) and increased longevity significantly lower than those with higher income. Clinicians should understand potential drivers of restoration choice, so they can be discussed with individual patients to obtain consent. It is important that policy makers consider general population preferences for restorative outcomes and services, with an awareness of how income affects these, when considering the potential phase-out of amalgam restorations.

直接后牙修复通常在龋齿处理后提供。汞合金的使用已经逐步减少，并且正在探索到 2030 年逐步淘汰的可行性。替代性直接修复材料在结果和提供方面有所不同。本研究旨在了解英国人口对不同修复属性的偏好以及他们对修复服务和结果的支付意愿 (WTP)。离散选择实验 (DCE) 是在患者和公众参与的情况下设计的，并使用在线调查分发给英国普通人群的代表性样本。受访者在 7 种属性（等待填充、临床医生类型、填充颜色、手术时间、填充后可能不适、填料的平均寿命和成本）。包括选择退出（不治疗）。混合逻辑模型用于数据分析。计算属性级别和相对属性重要性的边际 WTP。总共有 1,002 名受访者完成了 DCE。总体而言，受访者愿意支付 39.52 英镑将等待治疗的 6 周减少到 2 周，愿意支付 13.55 英镑接受牙医而不是治疗师的治疗，41.66 英镑将填充颜色从银色/灰色更改为白色，0.27 英镑每分钟减少治疗时间，从持续性术后疼痛转变为无术后疼痛需要 116.52 英镑，以及每年增加 5.44 英镑的修复寿命。支付能力影响支付意愿，低收入受访者更有可能选择退出治疗和价值恢复颜色（白色），延长寿命明显低于高收入者。临床医生应了解修复选择的潜在驱动因素，以便与个别患者进行讨论以获得同意。重要的是，政策制定者在考虑可能逐步淘汰汞合金修复时，应考虑一般人群对修复结果和服务的偏好，并了解收入如何影响这些偏好。
