The aim of the present study was to evaluate the reduction in bacterial loading using 3.8% as an irrigating solution in pulpectomized primary molars.
A randomized, controlled clinical trial was performed that included primary molars with pulp necrosis. Sixty necrotic canals were included, 30 irrigated with 3.8% SDF (experimental group) and 30 with 1% NaOCl solution (control group); in all cases, two microbiological samples from within the canals were taken with sterile paper points, the first after the canal opening and before the first irrigation, and the second after instrumentation and final irrigation, before obturation. All samples were evaluated by Agar plate method.
The results were statistically analyzed by student "t" test. After analyzing samples before and after irrigation in the control group (NaOCl), we found a strong significant decrease of bacterial load ( = < 0.001). The same occurred in the 3.8% SDF group samples ( = < 0.001). When both groups were compared post irrigation, a statistically significant difference was observed in favor of 3.8 % SDF.
3.8% SDF can be suggested as an alternative irrigant for pulpectomy of necrotic teeth.

本研究的目的是评估在乳牙牙髓切断术中使用3.8%的溶液作为冲洗液时细菌载量的减少情况。
进行了一项随机对照临床试验，纳入了患有牙髓坏死的乳牙。共纳入60条坏死根管，30条用3.8%的次氯酸钠溶液冲洗（试验组），30条用1%的次氯酸钠溶液冲洗（对照组）；在所有病例中，用无菌纸尖从根管内采集两份微生物样本，第一份在根管开放后、第一次冲洗前采集，第二份在器械操作和最终冲洗后、充填前采集。所有样本均采用琼脂平板法进行评估。
采用学生t检验对结果进行统计学分析。在分析对照组（次氯酸钠）冲洗前后的样本后，我们发现细菌载量有极显著下降（P<0.001）。3.8%的次氯酸钠溶液组样本也出现了同样的情况（P<0.001）。冲洗后比较两组时，观察到有利于3.8%次氯酸钠溶液的统计学显著差异。
3.8%的次氯酸钠溶液可作为坏死牙髓切断术的替代冲洗液。
