The sensation of pain can elevate anxiety levels, establishing a cyclical pattern that may result in the avoidance or premature termination of dental procedures. Previous endeavors employing various methods and products have produced varied outcomes. Jet injection systems, employing high pressure and velocity to deliver anesthesia without needles, offer a non-invasive option for local anesthesia administration. To assess and measure pain perception levels in a pediatric population during the restoration of young permanent teeth, comparing a needle-free injection system with the traditional dental needle method. Sixty participants with young permanent first molars requiring indirect pulp capping were enrolled, all under the care of a single operator. A simple randomization method was employed, utilizing sequentially numbered, opaque, sealed envelopes to allocate participants into two intervention groups: Group 1 and Group 2. Group 1 received traditional needle syringe anesthesia, while Group 2 received the needle-less injection system, Injex (INJEX Pharma AG, Germany). Following topical anesthesia application, local anesthesia was administered, and indirect pulp capping was performed. The Face, Legs, Activity, Cry, Consolability Scale (FLACC), Wong-Baker Scale, Time of local anesthesia (LA) Administration, Frankl Behavior Rating Scale (FBRS), and Pulse rate were evaluated and recorded at various intervals. The needle-less injection system required approximately 26.2 seconds for anesthesia administration, significantly less time than the traditional syringe ( < 0.001). FBRS score analysis revealed no significant differences between groups at all intervals. FLACC score analysis during anesthesia administration indicated lower scores in the needle-free injection group ( < 0.001). Evaluation of Wong Baker Scale (WBS) scores showed higher values in the traditional syringe needle group ( < 0.05). Using the Injex system presents a promising alternative for dental anesthesia administration, enhancing patient comfort and alleviating fear associated with traditional injections.
疼痛感觉会提高焦虑水平，建立一个循环模式，可能导致牙科治疗的回避或过早终止。以前使用各种方法和产品的努力产生了不同的结果。喷射注射系统采用高压和高速将麻醉剂无针输送，为局部麻醉管理提供了一种非侵入性的选择。为了评估和测量儿童在修复年轻恒牙时的疼痛感知水平，比较无针注射系统与传统牙科针方法。纳入了 60 名需要间接牙髓盖髓术的年轻恒牙第一磨牙的参与者，所有参与者均由一名操作人员护理。采用简单随机化方法，使用连续编号、不透明、密封的信封将参与者分配到两个干预组：第 1 组和第 2 组。第 1 组接受传统的针筒注射器麻醉，第 2 组接受无针注射系统 Injex（INJEX Pharma AG，德国）。局部麻醉应用后，给予局部麻醉，并进行间接牙髓盖髓术。在不同时间间隔评估和记录面部、腿部、活动、哭声、安慰性、可安慰性评分（FLACC）、Wong-Baker 量表、局部麻醉（LA）给药时间、Frankl 行为评分量表（FBRS）和脉搏率。无针注射系统用于麻醉的时间约为 26.2 秒，明显短于传统注射器（<0.001）。FBRS 评分分析在所有时间间隔内均未显示组间有显著差异。FLACC 评分分析在麻醉期间，无针注射组的分数较低（<0.001）。评估 Wong Baker 量表（WBS）评分显示传统注射器针头组的分数较高（<0.05）。使用 Injex 系统为牙科麻醉管理提供了一种有前途的替代方法，增强了患者的舒适度，并减轻了与传统注射相关的恐惧。
