Effectiveness of anterior middle superior alveolar injection using a computer-controlled local anesthetic delivery system for maxillary periodontal flap surgery

Background. 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. Methods. 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. Results. 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. Conclusion. CCLADS can be an effective and pain-free alternative to conventional local anesthetic procedures.

The study aims to evaluate the anesthetic effectiveness of the Anterior and Middle Superior Alveolar (AMSA)injection administered through a computer-controlled local anesthetic delivery system (CCLAD), and compare it with the traditional buccal and palatal injections used to anesthetize maxillary primary molars.Materials and methods: the sample included 80 primary maxillary molars, divided into 2 equal groups:Pulpotomy and extraction groups. Each group was divided equally into 4 subgroups: A. First molars anesthetized with the traditional technique, B. first molars anesthetized with the CCLAD, C. second molars anesthetized with the traditional technique, and D. second molars anesthetized with the CCLAD. The evaluation was done single blind using SEM scale. Results: the AMSA injection with the CCLAD was found to be effective in anesthetizing maxillary primary molars in pulpotomy and extraction procedures. There was no significant difference between the two anesthetic techniques except in the step of gingival retraction buccally in, which the traditional injections were more effective than the CCLAD during extractions. No significant difference was found between first and second primary molars in the effectiveness of both techniques. Conclusion:the AMSA injection using CCLAD was found to be effective in children.
