The use of needless local anaesthesia systems in dentistry can be of a help in treating needle phobia patients. The aim of this comfort study was to compare a classical local infiltration anaesthesia with a needle-free system. INJEX (ROSCH AG Germany). A split mouth design study was performed. All patients in this study needed 2 restorations. In order to receive objective information on both systems needle-phobia patients were banned. Therefore the first restoration was performed with the classical system (with needle) and the well-acceptance was evaluated. The second restoration was done with the needle-free system. Both patient and dental practitioner performed an evaluation after each treatment. Evaluation by the patient was given by a questionnaire on the comfort of the treatment using Faces Pain Scale, Lickert Scale and a modified version of the Abbreviated Acceptability Rating Profile. By the dental practitioner the comfort of the treatment and the amount of local anaesthesia needed was evaluated. The study was approved by the ethical committee of Ghent University Hospital Belgium.
The INJEX system can be a valuable alternative to use in paediatric dentistry, although non needle phobia patients in this study did not preferred the needle free INJEX system above the classical local injection.
牙科中使用无针局部麻醉系统有助于治疗恐针患者。这项舒适性研究的目的是比较传统局部浸润麻醉与无针系统（德国ROSCH AG公司的INJEX）。进行了一项双盲设计研究。本研究中的所有患者都需要进行2次修复治疗。为了获得关于这两种系统的客观信息，排除了恐针患者。因此，第一次修复使用传统系统（有针），并评估患者的接受程度。第二次修复使用无针系统。每次治疗后，患者和牙科医生都要进行评估。患者通过使用面部疼痛量表、利克特量表和简化可接受性评分量表的改良版问卷对治疗的舒适度进行评估。牙科医生对治疗的舒适度和所需局部麻醉量进行评估。该研究得到了比利时根特大学医院伦理委员会的批准。
INJEX系统在儿童牙科中可能是一种有价值的替代方法，尽管本研究中的非恐针患者并不比传统局部注射更喜欢无针的INJEX系统。
