Abstract：
OBJECTIVE: The aim of the current study was to assess the cleaning and smear layer removal efficacy of two different rotary files with or without chemical agents on primary teeth.
METHODS: For the study, 90 extracted primary maxillary incisors without internal or external resorption and with at least two-thirds of complete roots were chosen. Then, based on the kind of instruments used to clean and shape the canals, they were randomly assigned to three experimental groups, each consisting of 30 teeth. Group-I: The canal was instrumented manually with K-files, Group-II: The canal was instrumented with Kedo-S files, Group-III: The canal was instrumented with Kedo-SG Blue files. After the canals were finally instrumented, 2 mL of QMixTM solution was used to irrigate 15 samples from each group. The samples were subsequently allowed to remain in the canals for 90 seconds in order to eliminate the smear layer. After that a stereomicroscope was used to assess the cleaning effectiveness.
RESULTS: With irrigant solution, the highest mean value was found in manual K-files (2.86 ± 0.34), followed by Kedo-S files group (1.34 ± 0.26) and Kedo-SG Blue files (1.28 ± 0.18). Without irrigant solution, the highest mean value was found in manual K-files (2.92 ± 0.22) followed by Kedo-S files group (1.44 ± 0.18) and Kedo-SG Blue files (1.36 ± 0.14). There was a statistically significant difference found at all the three levels.
CONCLUSIONS: On conclusion, the current study\'s findings demonstrated that irrigation solution was significantly more effective in cleaning and removing smear layers from pediatric rotary files than manual K-files.
CONCLUSIONS: The effectiveness of endodontic therapy depends on a successful chemomechanical preparation. The canals are instrumented using either hand files or rotary instruments; there are several irrigation and instrumentation techniques. In order to completely sterilize the canals, chemical agents are utilized for irrigation during instrumentation. Due to their numerous biological, antibacterial, anti-inflammatory, and antioxidant qualities, many natural compounds are also utilized as irrigants. How to cite this article: Abushanan A.

摘要：
目的：本研究的目的是评估两种不同的旋转牙列在使用或不使用化学试剂的情况下对乳牙的清洁和涂抹层去除功效。
方法：对于研究，选择了90个无内部或外部吸收且至少有三分之二完整根的上颌切牙。然后，根据用于清洁和塑造运河的仪器种类，他们被随机分配到三个实验组，每个由30颗牙齿组成。第一组:运河用K文件手动检测，第二组:运河里装有Kedo-S文件，第三组：运河装有Kedo-SGBlue文件。在运河最终被仪器化之后，使用2mL的QMixTM溶液冲洗来自每组的15个样品。随后使样品在管道中保留90秒以消除涂抹层。之后,使用立体显微镜来评估清洁效果。
结果：使用冲洗液，在手动K文件中发现最高的平均值(2.86±0.34)，其次是Kedo-S文件组（1.34±0.26）和Kedo-SGBlue文件（1.28±0.18）。没有冲洗溶液，在手动K文件中发现最高的平均值(2.92±0.22),其次是Kedo-S文件组(1.44±0.18)和Kedo-SGBlue文件(1.36±0.14).在所有三个水平上都有统计学上的显着差异。
结论：结论，目前的研究结果表明,冲洗溶液在清洁和去除儿科旋转文件上的涂抹层方面比手动K文件更有效.
结论：牙髓治疗的有效性取决于成功的化学机械制剂。使用手动文件或旋转仪器对运河进行测量；有几种灌溉和仪器技术。为了彻底消毒运河，化学试剂用于仪器灌溉。由于其众多的生物，抗菌，抗炎,和抗氧化品质，许多天然化合物也被用作灌溉剂。如何引用这篇文章：AbushananA.在原始牙齿上使用/不使用化学试剂的各种旋转文件的涂抹层去除能力的评估：体外研究。JContempDentPract2024；25（4）：354-357。
