. Local anesthesia is given to decrease pain perception during dental treatments, but it may itself be a reason for pain and aggravate the dental fear. Computer-controlled local anesthetic delivery system (CCLADS) is one of the alternatives for decreasing the patients' pain during local anesthesia. This study compared the time required for the recovery from anesthesia, pain/discomfort during injection and pain/discomfort 24 hours after administering local anesthesia with CCLADS, a standard self-aspirating syringe and a conventional disposable 2-mL syringe. The study was conducted on 90 subjects (an age group of 20-40 years), who suffered from sensitivity during cavity preparation. They were randomly divided into three groups of 30 individuals each to receive intraligamentary anesthesia (2% lignocaine with 1:80,000 adrenaline) using either of the three techniques: CCLADS, a standard self-aspirating syringe, or a conventional disposable 2-mL syringe. The onset of anesthesia, time required for recovery from anesthesia (in minutes), pain/discomfort during injection and pain/discomfort 24 hours after administering local anesthesia were recorded. The time required for the onset of anesthesia and recovery from anesthesia was shorter with CCLADS (4.83±2.31 and 34.2±1.895, respectively) as compared to the standard self-aspirating group (10.83±1.90 and 43.5±7.581, respectively) and the conventional group (11.00±2.03 and 43.5±6.453, respectively) (P<0.001). The patients in the CCLADS group experienced no pain during local anesthesia administration as compared to the patients in the self-aspirating and conventional groups. The CCLADS and self-aspirating groups showed lower pain response as compared to the conventional group for pain after 24 hours. CCLADS can be an effective and pain-free alternative to conventional local anesthetic procedures.
局部麻醉用于在牙科治疗期间降低疼痛感知，但它本身可能是疼痛的一个原因，并加剧牙科恐惧。计算机控制局部麻醉给药系统（CCLADS）是在局部麻醉期间减轻患者疼痛的替代方法之一。本研究比较了使用CCLADS、标准自吸式注射器和传统一次性2毫升注射器进行局部麻醉后麻醉恢复所需时间、注射期间的疼痛/不适以及24小时后的疼痛/不适。该研究针对90名（年龄在20至40岁之间）在窝洞制备期间有敏感症状的受试者进行。他们被随机分为三组，每组30人，分别使用三种技术之一接受韧带内麻醉（2%利多卡因加1:80,000肾上腺素）：CCLADS、标准自吸式注射器或传统一次性2毫升注射器。记录麻醉起效时间、麻醉恢复所需时间（以分钟为单位）、注射期间的疼痛/不适以及局部麻醉给药后24小时的疼痛/不适。与标准自吸式组（分别为10.83±1.90和43.5±7.581）和传统组（分别为11.00±2.03和43.5±6.453）相比，CCLADS组的麻醉起效和恢复所需时间更短（分别为4.83±2.31和34.2±1.895）（P<0.001）。与自吸式组和传统组的患者相比，CCLADS组的患者在局部麻醉给药期间没有疼痛。与传统组相比，CCLADS组和自吸式组在24小时后的疼痛方面显示出较低的疼痛反应。CCLADS可以成为传统局部麻醉程序的一种有效且无疼痛的替代方法。
