Abstract:
Dental phobia is the most prevalent fear in all age groups, across gender, and in all countries. One of the primary identified sources is the fear of dental injections in the dental phobia or the high dental fear and anxiety groups. The purpose of this study was to clinically evaluate the computer controlled anesthetic device and to compare it with traditional methods of dental anesthetic delivery. Fifty(mean age : 25.6 yrs) systemically and periodontally healthy volunteers participated in this study. The subjects were given contralateral buccal and palatal injections. One side was injected with the computer-controlled anesthetic device with a microprocessor and an electric motor to precisely regulate flow rate during administration : The experimental group. The control side was injected with a standard manual syringe, in which flow rate and pressure are operator-dependent and can't be controlled accurately:The control group. The subjects described their perceived pain experiences with two subjective scales. The results of this study were as follows: 1. The computer-controlled anesthetic device was significantly less painful than conventional syringe injection. 2. The female subjects reported more pain than the male subjects. But, there were no statistical differences. 3. The anesthetic effect of both methods did not show any difference. In this study, it may be concluded that pain levels decreased significantly when the computer-controlled anesthetic device was used.
