To assess retrospectively the success rate of calcium hydroxide with iodoform as a filling material in pulpectomies of primary molars with irreversible pulpitis or pulp necrosis, and to evaluate factors that affect outcomes.
This study consisted of records of 73 patients with primary molars treated with pulpectomy with high quality radiographs. Treatment was considered successful clinically if the tooth was not extracted and radiographs showed a decrease or no change in preexisting pathologic radiolucent defects.
Follow-up ranged from three to 39 months (median: 21.5 months). The success rate of teeth restored with a stainless steel crown (SSC) on the same appointment (88.9 percent) was higher than for teeth that received a temporary restoration ( =0.001). There was no statistically significant difference between the success rate and the extent of resorption of root canal filling material. Primary second molars had a higher success rate than first molars ( =0.018). No difference was found between the level of pulpectomy filling and treatment success ( =0.17).
Pulpectomies done with calcium hydroxide and iodoform had an overall success rate of 74 percent. If restored with an SSC, the success rate increased to 88.9 percent. Resorption of the paste did not affect the success rate.
回顾性评估氢氧化钙联合碘仿作为填充材料在伴有不可复性牙髓炎或牙髓坏死的乳磨牙牙髓切断术中的成功率，并评估影响治疗效果的因素。
本研究纳入了 73 例因牙髓切断术而接受治疗的乳磨牙患者的记录，这些患者均有高质量的射线照片。如果牙齿未被拔除且射线照片显示先前存在的病理性半透明缺陷有减少或无变化，则临床认为治疗成功。
随访时间为 3 至 39 个月（中位数：21.5 个月）。在同一次就诊时用不锈钢冠（SSC）修复的牙齿（88.9%）的成功率高于使用临时修复体的牙齿（ =0.001）。根管填充材料的吸收程度与成功率之间无统计学差异。第二乳磨牙的成功率高于第一乳磨牙（ =0.018）。牙髓切断术填充水平与治疗效果之间无差异（ =0.17）。
用氢氧化钙和碘仿进行牙髓切断术的总体成功率为 74%。如果用 SSC 修复，成功率增加到 88.9%。糊剂的吸收不会影响成功率。
