The purpose of this ex-vivo study is to evaluate the efficacy of three irrigation techniques in the reduction of in root canal.
Eighty healthy maxillary anteriors were employed in this investigation. The bacteria was left on teeth for 7 days while they were kept. Once teeth were contaminated, they were randomly divided into three groups of 20 for experimentation and a control group of 20 for comparison. NaviTip FX was used to irrigate Group I, the Max-I-probe was used to water Group II, and the Endovac system was used to water Group III. The number of colony forming units (CFUs) was determined by growing bacteria from root canal samples for 2 days in Brain heart infusion agar after chemo-mechanical operations.
There was a substantial decrease in bacterial numbers across all experimental groups compared to group IV (control). Group III (Endovac) had the fewest bacterial colonies among the test groups. There were no discernible changes between Group I (the Navitip FX) and Group II (the Max I probe).
Endovac was the most effective of the three irrigation methods for reducing CFUs. This study's findings lend credence to the idea that the apical negative pressure approach has more potential than the conventional irrigation delivery system for achieving an enhanced antibacterial impact.
本体外研究的目的是评估三种冲洗技术在减少根管内细菌方面的疗效。
本研究采用80颗健康上颌前牙。在保存牙齿的同时,将细菌留在牙齿上7天。牙齿一旦被污染,就随机分为三组,每组20颗用于实验,一组20颗作为对照组用于比较。第一组使用NaviTip FX冲洗,第二组使用Max-I-probe冲洗,第三组使用Endovac系统冲洗。在化学机械操作后,通过将根管样本中的细菌在脑心浸液琼脂中培养2天来确定菌落形成单位(CFU)的数量。
与第四组(对照组)相比,所有实验组的细菌数量均显著减少。在测试组中,第三组(Endovac)的细菌菌落最少。第一组(Navitip FX)和第二组(Max I探针)之间没有明显变化。
Endovac是三种冲洗方法中减少CFU最有效的方法。本研究结果支持以下观点:与传统冲洗输送系统相比,根尖负压方法在实现增强抗菌效果方面具有更大的潜力。
