To compare the postoperative pain of continuous rotation and reciprocating movements after pulpectomy of non-vital primary molars and determine associated risk factors. 146 children aged 4-8 years with one primary molar indicated for pulpectomy were randomly assigned to two equal groups: those instrumented with continuous rotation motion (Hyflex EDM Coltene/Whaledent) and reciprocating motion (Reciproc R25 (VDW)). A 4-point pain scale was used to assess postoperative pain frequencies, which were compared at different intervals using the Chi-square test. Postoperative pain risk factors were determined using logistic regression analysis. There was no statistically significant difference between the follow-ups. Gender, pulp status, and radiographic radiolucency increased the risk of postoperative pain incidence. Postoperative pain likelihood in children with chronic apical periodontitis was 8.72 times that of children with necrotic pulps. Postoperative pain after instrumentation with both kinematics was comparable. Postoperative pain incidence is increased by preoperative pulp condition, radiographic radiolucency, and gender.
比较非活髓乳磨牙牙髓切除术后连续旋转和往复运动的术后疼痛，并确定相关的危险因素。将 146 名年龄在 4-8 岁、有一颗乳磨牙需要牙髓切除的儿童随机分为两组：一组采用连续旋转运动（Hyflex EDM Coltene/Whaledent），另一组采用往复运动（Reciproc R25 (VDW)）。采用 4 分疼痛量表评估术后疼痛频率，并采用卡方检验比较不同时间点的差异。使用逻辑回归分析确定术后疼痛的危险因素。在随访中没有发现统计学上的显著差异。性别、牙髓状态和放射影像学上的不透明性增加了术后疼痛发生的风险。患有慢性根尖周炎的儿童发生术后疼痛的可能性是牙髓坏死儿童的 8.72 倍。两种运动学方法的术后疼痛发生率相当。术前牙髓状态、放射影像学不透明性和性别增加了术后疼痛的发生率。
