This study aims to compare the pain perception associated with the needle-free system (Comfort-In™) and the standard needle injection method during root canal treatments in adults.
Forty-four maxillary premolar teeth of the patients that applied to university for treatment and needed endodontic treatment were included in the study. Patients were anesthetized with two different injection methods; needle-free injection and conventional dental injection. In both groups, oxygen saturation and pulse measurements of the patients were recorded at 30-second intervals for 2 minutes before anesthesia and 4 minutes after anesthesia. Pain during the injection and opening of the access cavity preparation was recorded according to Visual Analog Scale (VAS). The data were analyzed according to a statistical program.
In this study, a significant difference was found between the groups in terms of pain during anesthesia administration and the access cavity preparation (p<0.001). There were no significant differences in terms of gender and age (p>0.05). There was no significant difference between the groups in terms of oxygen saturation and pulse values before and after treatment (p>0.05).
Needle-free injection makes the treatment more comfortable for patients with injection fear and anxiety, making the procedure easier for the physician and the patient. (EEJ-2024-12-197).
本研究旨在比较成人根管治疗期间无针注射系统（Comfort-In™）与标准针剂注射方法相关的疼痛感受。
本研究纳入了44颗向大学申请治疗且需要进行牙髓治疗的上颌前磨牙。患者采用两种不同的注射方法进行麻醉，即无针注射和传统牙科注射。两组患者在麻醉前2分钟和麻醉后4分钟均每隔30秒记录一次血氧饱和度和脉搏测量值。根据视觉模拟量表（VAS）记录注射过程中和开髓预备时的疼痛情况。数据采用统计软件进行分析。
本研究发现，两组在麻醉给药和开髓预备时的疼痛方面存在显著差异（p<0.001）。在性别和年龄方面无显著差异（p>0.05）。两组在治疗前后的血氧饱和度和脉搏值方面无显著差异（p>0.05）。
无针注射使有注射恐惧和焦虑的患者在治疗过程中感觉更舒适，使医生和患者的操作都更简便。（EEJ-2024-12-197）
