The present study aimed to evaluate and compare six different materials commonly used for filling the root canals of primary teeth for antimicrobial efficacy against some of the microorganisms commonly found in infected root canals.
In this experimental in vitro study six root canal filling materials were tested for antimicrobial efficacy against eight microbial strains using the agar diffusion method.
Zinc oxide eugenol paste exhibited the strongest antimicrobial potential followed by Endoflas, zinc oxide-calcium hydroxide-sodium fluoride mixture, zinc oxide-calcium hydroxide mixture and calcium hydroxide paste (Apexcal). The addition of sodium fluoride to the zinc oxide-calcium hydroxide mixture enhanced the antimicrobial efficacy. Metapex demonstrated minimal inhibition and Vaseline was non-inhibitory.
All the test filling materials demonstrated varying antimicrobial activity against the microorganisms tested. Zinc oxide eugenol paste and materials containing zinc oxide were found to be more effective against the microorganisms compared to materials without zinc oxide.
本研究旨在评估和比较六种常用于乳牙根管充填的不同材料，针对感染根管中常见的一些微生物的抗菌效果。
在这项体外实验研究中，使用琼脂扩散法测试了六种根管充填材料对八种微生物菌株的抗菌效果。
氧化锌丁香酚糊剂显示出最强的抗菌潜力，其次是Endoflas、氧化锌 - 氢氧化钙 - 氟化钠混合物、氧化锌 - 氢氧化钙混合物和氢氧化钙糊剂（Apexcal）。向氧化锌 - 氢氧化钙混合物中添加氟化钠可增强抗菌效果。Metapex显示出最小的抑制作用，凡士林无抑制作用。
所有测试的充填材料对所测试的微生物均表现出不同程度的抗菌活性。与不含氧化锌的材料相比，氧化锌丁香酚糊剂和含氧化锌的材料对微生物更有效。
