BARROS, T. P et al. Comparative Study Between the Conventional Local Anesthetic Technique and the Computer-controlled Local Anesthetic. Int. J. Odontostomat. [online]. 2013, vol.7, n.2, pp.175-178. ISSN 0718-381X.

Pain control is one of the most important aspects contributing that the patient has a positive behavior in the dental office. However, this still constitutes a challenge for the dentist when treating anxious patients, because the administration of local anesthesia is the cause of many patients to avoid dental treatment. With the purpose of reducing pain sensation for patients and promote greater comfort for patients and professionals was developed a computerized anesthesia injection method. The aim of this investigation was to compare the conventional local anesthetic technique with the computer-controlled local anesthetic. Participated in this study 30 volunteers patients who had indication for bilateral surgical extraction of lower third molars. The patients, randomly selected, were subjected to each of the two mentioned anesthetic techniques (conventional and computer-controlled). Although the degree of professional satisfaction with the computer-controlled local anesthetic technique has been significant, the most of them reported to prefer the conventional method. There was no significant hemodynamic changes in any of the two methods used in this study. The computer-controlled local anesthetic technique was simple, effective and safe. The patients enrolled in this study responded better to the computer-controlled local anesthetic technique, reporting less pain.
