Pain control, which is necessary during most dental procedures, is administered by injecting a local anaesthetic. Because the injection itself can be painful, the procedure via which pain is reduced warrants continued investigation. Only a few studies regarding the reaction of children to dental needle insertion without the use of topical anaesthetics have been reported. This study was conducted to evaluate the efficacy of the local anaesthetic procedure without topical application as compared to the conventional insertion technique for alleviating pain in children receiving local anaesthesia injections.
For the alternative injection procedure, the dentist quickly and gently pulled or pushed the clean and dried loose tissue at the injection site over the tip of the needle to a depth of 1 to 1.5 mm. When the end of the bevel of the needle tip entered the tissue, a few drops of solution were released, after which the needle was advanced to its proper and intended depth to continue anaesthetic release.
There was a significant difference regarding the pain response between the alternative insertion technique (less painful) and the conventional one according to Sound, Eye, and Motor (SEM) scale ratings (P < 0.000). No significant difference was observed in the response between the maxilla and mandible, nor between boys and girls, between the conventional and alternative techniques.
This alternative technique can reduce discomfort in paediatric dental patients and allow the clinician to administer a superficial local anaesthesia injection before the needle is advanced into deeper tissue. This technique is simple, quick, devoid of additional costs, and potentially more effective than the conventional needle insertion method.
在大多数牙科手术中都需要进行疼痛控制,方法是注射局部麻醉剂。由于注射本身可能会引起疼痛,因此需要继续研究减轻疼痛的方法。只有少数研究报告了在不使用局部麻醉的情况下儿童对牙科注射针插入的反应。本研究旨在评估在接受局部麻醉注射的儿童中,与常规插入技术相比,不使用局部麻醉剂的局部麻醉程序的效果,以减轻疼痛。
对于替代注射程序,牙医快速轻柔地将注射部位的清洁干燥的松动组织拉或推到针尖端 1 到 1.5 毫米的深度。当针尖端斜面的末端进入组织时,会释放出几滴溶液,然后将针推进到适当的深度以继续释放麻醉剂。
根据 Sound、Eye、and Motor(SEM)评分,替代插入技术(疼痛较轻)与常规插入技术之间的疼痛反应有显著差异(P < 0.000)。在常规和替代技术之间,上颌骨和下颌骨之间、男孩和女孩之间的反应没有显著差异。
这种替代技术可以减少儿科牙科患者的不适,并允许临床医生在将针推进到更深的组织之前进行浅表局部麻醉注射。该技术简单、快速、无需额外费用,并且比常规的针插入方法更有效。
