In pulpectomy, to remove the inflamed or diseased pulp tissues and smear layer, the root canal is disinfected with mechanical instrumentation and copious irrigation.
The purpose of this present study is to evaluate the antibacterial efficacy of etidronic acid as an irrigant in primary teeth.
A total of 60 necrotic primary teeth in children aged 3-8 years were included. Of these, 30 were irrigated with 2% chlorhexidine (CHX) gluconate (group I) and 30 with 9% etidronic acid (group II). Two microbiological samples were collected with sterile paper points from the canal in both groups during the pulpectomy process-first after access opening and before the first irrigation (S1), and second after instrumentation and final irrigation, before filling (S2). The presence of was determined using colony-forming units per milliliter (CFU/mL) in all samples (S1 and S2).
After analyzing the samples before and after irrigation in groups I and II, there was a statistically significant reduction in CFU/mL ( < 0.05). Group II had a statistically significant advantage when the two groups were compared after irrigation.
As a result, etidronic acid can be recommended as a pulpectomy irrigating solution for necrotic primary teeth.

在牙髓摘除术中，为去除发炎或患病的牙髓组织及玷污层，需通过机械预备和大量冲洗对根管进行消毒。
本研究旨在评估依替膦酸作为乳牙冲洗液的抗菌效果。
纳入3 - 8岁儿童的60颗坏死乳牙。其中，30颗用2%葡萄糖酸氯己定（CHX）冲洗（I组），30颗用9%依替膦酸冲洗（II组）。在牙髓摘除过程中，两组均用无菌纸尖从根管采集两份微生物样本——一份在开髓后首次冲洗前（S1），另一份在预备和最终冲洗后、充填前（S2）。所有样本（S1和S2）均采用每毫升菌落形成单位（CFU/mL）来确定细菌的存在情况。
分析I组和II组冲洗前后的样本后发现，CFU/mL有统计学显著降低（P < 0.05）。冲洗后两组比较时，II组具有统计学显著优势。
因此，依替膦酸可推荐作为坏死乳牙牙髓摘除术的冲洗液。
