The application of disinfectants on dental instruments is one way to prevent cross-infection. The urgency in this research is ozone water as a disinfectant is still limited and no research has been found on the use of ozone water on tooth extraction instruments. However, ozone has antibacterial properties so researchers are interested in studying the effectiveness of ozone water as a disinfectant when compared to the commonly used 4.8% chloroxylenol. This study aimed to determine the effectiveness of disinfection of ozone water and 4.8% chloroxylenol in reducing the number of bacterial colonies on dental extraction instruments at the Universitas Sumatera Utara Dental and Oral Hospital.
The samples used were mandibular molar forceps have been used in tooth extraction procedures. This study was experimental and used 30 sample, where each group consisted of 10 tooth extraction instruments. The treatment group used ozone water and 4.8% chloroxylenol and the negative control group was cleaned with distilled water. The ozone water group was produced with an ozone generator with a concentration of 15 mg/L for 20 minutes. Then the active side of tooth extraction forceps was soaked for 30 minutes. In the 4.8% chloroxylenol (dettol®) group, the active side of the mandibular molar tooth extraction forceps was soaked in 250 mL for 60 minutes. In the control group, the mandibular molar tooth extraction forceps were rinsed with distilled water. After that, the sample was counted using a bactery colony counter.
The results of the data analysis showed a p-value ≤0.001, which means there was a significant difference in the disinfection using ozone water and 4.8% chloroxylenol on the number of bacterial colonies on dental extraction instruments.
From this study it can be said that ozone water is more effective in disinfecting than 4.8% chloroxylenol.
在牙科器械上应用消毒剂是预防交叉感染的一种方法。本研究的紧迫性在于，臭氧水作为一种消毒剂的应用仍然有限，且尚未发现有关在拔牙器械上使用臭氧水的研究。然而，臭氧具有抗菌特性，因此与常用的4.8%氯二甲酚相比，研究人员有兴趣研究臭氧水作为消毒剂的有效性。本研究旨在确定臭氧水和4.8%氯二甲酚在苏门答腊北部大学口腔医院对拔牙器械上细菌菌落数量的消毒效果。
所使用的样本是在拔牙手术中用过的下颌磨牙钳。本研究为实验性研究，使用30个样本，每组由10把拔牙器械组成。治疗组使用臭氧水和4.8%氯二甲酚，阴性对照组用蒸馏水清洗。臭氧水组由臭氧发生器产生，浓度为15 mg/L，作用20分钟。然后将拔牙钳的活动侧浸泡30分钟。在4.8%氯二甲酚（滴露®）组中，将下颌磨牙拔牙钳的活动侧浸泡在250 mL中60分钟。在对照组中，下颌磨牙拔牙钳用蒸馏水冲洗。之后，使用细菌菌落计数器对样本进行计数。
数据分析结果显示p值≤0.001，这意味着在拔牙器械上使用臭氧水和4.8%氯二甲酚对细菌菌落数量的消毒存在显著差异。
从本研究可以得出，臭氧水在消毒方面比4.8%氯二甲酚更有效。
