The Hall technique (HT) involves the placement of stainless steel crowns for treating asymptomatic carious primary teeth without tooth preparation or caries excavation.
To investigate whether temporomandibular dysfunction (TM-D) manifests in children after HT.
Healthy children (age: 5-9 years) with dentin caries were treated with HT in a university clinic, and TM-D signs and symptoms were monitored in this cohort clinical trial. The primary outcome was TM-D signs recorded using the clinical dysfunction index (Di) at pre-treatment: 0-, 1-, 3-, 6-, and 12-month follow-up visits. The secondary outcome was TM-D symptoms recorded using a questionnaire. The Di and symptoms were compared over time using McNemar's tests.
Thirty-nine children were followed for 12 months after HT treatment. Four children were detected as having dysfunction signs throughout the study: muscle pain on palpation and clicking. The symptoms 'hearing a sound within the jaw joint' or 'bite felt uncomfortable or unusual' were reported by another four children. The Di and TM-D symptoms were not significantly different between pre-treatment and follow-up visits (P > .05).
The HT does not seem to be connected to TM-D. Alternative TM-D assessment tools for studying non-persistent symptoms more comprehensively might be useful for future studies.
Hall 技术（HT）涉及在不进行牙齿预备或龋齿挖掘的情况下，用不锈钢冠治疗无症状龋坏的乳牙。
研究 HT 后儿童是否会出现颞下颌功能紊乱（TM-D）。
在大学诊所，对有牙本质龋的健康儿童（年龄：5-9 岁）进行 HT 治疗，并在这项队列临床试验中监测 TM-D 体征和症状。主要结局是使用临床功能障碍指数（Di）在治疗前（0、1、3、6 和 12 个月随访时）记录的 TM-D 体征。次要结局是使用问卷记录 TM-D 症状。使用 McNemar 检验比较随时间的 Di 和症状。
39 名儿童在 HT 治疗后随访 12 个月。在整个研究过程中，有 4 名儿童被检测到存在功能障碍迹象：触诊时肌肉疼痛和弹响。另外 4 名儿童报告有“颌关节内听到声音”或“咬合感觉不适或异常”的症状。Di 和 TM-D 症状在治疗前和随访时无显著差异（P>.05）。
HT 似乎与 TM-D 无关。未来的研究可能需要更全面地评估非持续性症状的替代 TM-D 评估工具。
