Children's pain in dentistry has undesirable short- and long-term consequences; therefore, less invasive treatments merit consideration.
To investigate procedural pain scores for two treatments for carious primary molars in New Zealand primary care.
This study was a split-mouth randomised control trial, with secondary outcome analysis. Children (4-8 years) with proximal carious lesions on matched primary molars had one tooth treated with the Hall technique (HT) and one treated with a conventional stainless steel crown (CT); treatment type and order of treatment were randomly allocated (allocation concealment). The Wong-Baker self-report pain scale measured pretreatment dental pain, procedural pain at each treatment and post-operative pain.
Data were analysed for 103 children: 49 children had the HT first and 54 children had the CT first. Procedural pain scores did not differ by treatment type, with 71.8% and 76.7% of children reporting low pain for the HT and the CT, respectively. Fewer children reported low procedural pain for the second treatment than the first (p = .047). Most children reported low procedural pain for both treatments (58.3%), although 41.7% experienced moderate-high procedural pain with at least one treatment.
The HT caused pain for as many children as the CT. There is an opportunity for better dental pain management in this setting.
儿童在牙科的疼痛会带来短期和长期的不良后果；因此，值得考虑采用侵入性更小的治疗方法。
调查新西兰初级保健中两种治疗龋齿乳磨牙的方法的操作疼痛评分。
这是一项分侧随机对照试验，具有次要结局分析。有近中龋损的匹配乳磨牙的 4-8 岁儿童，一侧牙齿采用 Hall 技术（HT）治疗，另一侧采用常规不锈钢冠（CT）治疗；治疗类型和治疗顺序随机分配（分配隐藏）。Wong-Baker 自我报告疼痛量表测量治疗前、每次治疗时的操作疼痛和术后疼痛。
对 103 名儿童进行了数据分析：49 名儿童先接受 HT，54 名儿童先接受 CT。操作疼痛评分不因治疗类型而异，HT 和 CT 的低疼痛报告率分别为 71.8%和 76.7%。第二次治疗比第一次治疗报告低操作疼痛的儿童更少（p=.047）。大多数儿童对两种治疗都报告了低操作疼痛（58.3%），尽管至少有一种治疗方法使 41.7%的儿童经历了中高度操作疼痛。
HT 引起的疼痛与 CT 一样多。在这种情况下，有机会更好地管理牙科疼痛。
