The Filling Children’s Teeth: Indicated Or Not? (FiCTION) randomised controlled trial (RCT) aimed to explore the clinical- and cost-effectiveness of managing dental caries in children’s primary teeth. The trial compared three management strategies: conventional caries management with best practice prevention (C + P), biological management with best practice prevention (B + P) and best practice prevention alone (PA)-based approaches. Recently, the concept of treatment acceptability has gained attention and attempts have been made to provide a conceptual definition, however this has mainly focused on adults. Recognising the importance of evaluating the acceptability of interventions in addition to their effectiveness, particularly for multi-component complex interventions, the trial design included a qualitative component. The aim of this component was to explore the acceptability of the three strategies from the perspectives of the child participants and their parents. Qualitative exploration, based on the concept of acceptability. Participants were children already taking part in the FiCTION trial and their parents. Children were identified through purposive maximum variation sampling. The sample included children from the three management strategy arms who had been treated and followed up; median (IQR) follow-up was at 33.8 (23.8, 36.7) months. Semi-structured interviews with thirteen child-parent dyads. Interviews were transcribed verbatim and analysed using a framework approach. Data saturation was reached after thirteen interviews. Each child-parent dyad took part in one interview together. The participants were eight girls and five boys aged 5–11 years and their parents. The children’s distribution across the trial arms was: C + P n = 4; B + P n = 5; PA n = 4. Three key factors influenced the acceptability of caries management in primary teeth to children and parents: i) experiences of specific procedures within management strategies; ii) experiences of anticipatory dental anxiety and; iii) perceptions of effectiveness (particularly whether pain was reduced). These factors were underpinned by a fourth key factor: the notion of trust in the dental professionals – this was pervasive across all arms. Overall children and parents found each of the three strategies for the management of dental caries in primary teeth acceptable, with trust in the dental professional playing an important role.

儿童和父母对“填装儿童牙齿：指示或非指示”（FiCTION）随机对照试验中的三种处理策略对乳牙龋齿的可接受性的观点-一项定性研究。

充填的儿童牙齿：是否已表明？（FiCTION）随机对照试验（RCT）旨在探讨治疗儿童乳牙龋齿的临床和成本效益。该试验比较了三种管理策略：具有最佳实践预防（C + P）的常规龋齿管理，具有最佳实践预防（B + P）和仅基于最佳实践预防（PA）的生物管理。近来，治疗可接受性的概念已经引起关注，并且已经尝试提供概念上的定义，但是这主要集中于成年人。认识到评估干预措施的有效性以及有效性的重要性，尤其是对于多成分的复杂干预措施，该试验设计包括定性成分。本部分的目的是从儿童参加者及其父母的角度探讨这三种策略的可接受性。基于可接受性概念的定性探索。参加者是已经参加FiCTION试验的儿童及其父母。通过有针对性的最大变异抽样确定儿童。样本包括来自三个管理策略部门的儿童，这些儿童已经过治疗和随访。中位数（IQR）随访时间为33.8（23.8，36.7）个月。半结构式采访十三对儿童父母双性恋。采访被逐字记录并使用框架方法进行分析。十三次采访后数据达到饱和。每个儿童父母双胞胎一起参加了一次采访。参加者是年龄在5-11岁之间的八个女孩和五个男孩以及他们的父母。儿童在审判各部门的分布为：C + P n = 4；B + P n = 5; PA n =4。三个关键因素影响了对儿童和父母的乳牙龋齿管理的可接受性：i）管理策略中特定程序的经验；ii）预期的牙齿焦虑的经历；以及 iii）对效果的看法（尤其是疼痛是否减轻）。这些因素由第四个关键因素来支撑：对牙科专业人员的信任概念–遍及各个领域。总体而言，儿童和父母发现，可以接受的三种治疗初生龋齿的策略中的每一种都是可以接受的，并且信任牙科专业人员起着重要作用。儿童在审判各部门的分布为：C + P n = 4；B + P n = 5; PA n =4。三个关键因素影响了对儿童和父母的乳牙龋齿管理的可接受性：i）管理策略中特定程序的经验；ii）预期的牙齿焦虑的经历；以及 iii）对效果的看法（尤其是疼痛是否减轻）。这些因素由第四个关键因素来支撑：对牙科专业人员的信任概念–遍及各个领域。总体而言，儿童和父母发现，可以接受的三种治疗初生龋齿的策略中的每一种都是可以接受的，并且信任牙科专业人员起着重要作用。儿童在审判各部门的分布为：C + P n = 4；B + P n = 5; PA n =4。三个关键因素影响了对儿童和父母的乳牙龋齿管理的可接受性：i）管理策略中特定程序的经验；ii）预期的牙齿焦虑的经历；以及 iii）对效果的看法（尤其是疼痛是否减轻）。这些因素由第四个关键因素来支撑：对牙科专业人员的信任概念–遍及各个领域。总体而言，儿童和父母发现，可以接受的三种治疗初生龋齿的策略中的每一种都是可以接受的，并且信任牙科专业人员起着重要作用。三个关键因素影响了对儿童和父母的乳牙龋齿管理的可接受性：i）管理策略中特定程序的经验；ii）预期的牙齿焦虑的经历；以及 iii）对有效性的看法（尤其是疼痛是否减轻）。这些因素由第四个关键因素来支撑：对牙科专业人员的信任概念–遍及各个领域。总体而言，儿童和父母发现，可以接受的三种治疗初生龋齿的策略中的每一种都是可以接受的，并且信任牙科专业人员起着重要作用。三个关键因素影响了对儿童和父母的乳牙龋齿管理的可接受性：i）管理策略中特定程序的经验；ii）预期的牙齿焦虑的经历；以及 iii）对效果的看法（尤其是疼痛是否减轻）。这些因素由第四个关键因素来支撑：对牙科专业人员的信任概念–遍及各个领域。总体而言，儿童和父母发现，可以接受的三种治疗初生龋齿的策略中的每一种都是可以接受的，并且信任牙科专业人员起着重要作用。iii）对效果的看法（尤其是疼痛是否减轻）。这些因素由第四个关键因素来支撑：对牙科专业人员的信任概念–遍及各个领域。总体而言，儿童和父母发现，可以接受的三种治疗初生龋齿的策略中的每一种都是可以接受的，并且信任牙科专业人员起着重要作用。iii）对效果的看法（尤其是疼痛是否减轻）。这些因素由第四个关键因素来支撑：对牙科专业人员的信任概念–遍及各个领域。总体而言，儿童和父母发现，可以接受的三种治疗初生龋齿的策略中的每一种都是可以接受的，并且信任牙科专业人员起着重要作用。
