Understanding the value the general population place on dentistry services is important for policymakers to aide service planning. Willingness to pay (WTP) is an economic method used to elicit the value of a good or service. The aim of this study is to estimate United Kingdom (UK) general population WTP for commonly provided scale and polish, and detailed and personalized oral hygiene advice (OHA), and to investigate what factors influence WTP.
Participants completed an online hypothetical WTP survey for scale and polish and detailed and personalized oral hygiene advice. The estimation sample consisted of 1405 participants, nationally representative of the UK general population in terms of age and sex. Regression analysis was used to estimate WTP and determine what factors are associated with WTP. Analyses were conducted including and excluding protest answers.
The mean (SD) WTP for a scale and polish is £26.77 (£21.91) excluding protest answers and £24.80 (£22.71) for the full sample. The mean (SD) WTP for detailed and personalized OHA is £16.56 (£19.75) excluding protest answers and £12.77 (£22.28) for the full sample. Participants on higher incomes, private attenders and those who stated that maintaining clean and healthy gums was important had higher WTP for both services. Participants in Scotland and Northern Ireland were WTP less than their English counterparts, reflecting the different regional specific payment systems.
The general UK population value scale and polish, and detailed and personalized OHA. This study provides estimates of WTP for these services which can be used to inform resource allocation decisions.
了解普通人群对牙科服务的重视程度，对政策制定者制定服务计划具有重要意义。支付意愿（WTP）是一种经济方法，用于评估商品或服务的价值。本研究旨在估算英国（UK）普通人群对常规洁牙和抛光以及详细个性化口腔卫生建议（OHA）的支付意愿，并探讨影响支付意愿的因素。
参与者完成了一项关于洁牙和抛光以及详细个性化口腔卫生建议的在线假设性 WTP 调查。估计样本由 1405 名参与者组成，在年龄和性别方面代表英国普通人群的全国代表性。回归分析用于估算 WTP，并确定哪些因素与 WTP 相关。进行了包括和排除抗议回答的分析。
排除抗议回答时，对洁牙和抛光的平均（SD）支付意愿为 26.77 英镑（21.91 英镑），全样本为 24.80 英镑（22.71 英镑）。排除抗议回答时，对详细个性化 OHA 的平均（SD）支付意愿为 16.56 英镑（19.75 英镑），全样本为 12.77 英镑（22.28 英镑）。收入较高、私人就诊者和那些表示保持清洁健康牙龈很重要的参与者对这两种服务的支付意愿较高。苏格兰和北爱尔兰的参与者的支付意愿低于其英格兰同行，反映了不同地区特定的支付系统。
英国普通人群重视洁牙和抛光以及详细个性化 OHA。本研究提供了这些服务的 WTP 估算值，可以用于为资源分配决策提供信息。
