Computerized anesthesia devices are valid and more comfortable
substitute to the usual, standard anesthesia.
As compared to the conventional anesthesia syringe, the computerized anesthesia offers significantly less pain compared with a standard anesthesia syringe. Although both obtained sufficient anesthetic depth to perform treatments, the majority of patients chose electronic anesthesia to be most satisfactory.
This randomized clinical trial compared pain perception concerning the use of conventional anesthesia and computerized system.
All in all, 40 patients requiring extractions, dental restorative, or periodontal treatment were subjected to two anesthesia methods: standard and electronically controlled anesthesia. They received both treatments in a blind way 1 week apart.
Following the use of anesthesia (in the upper dental nerve, palatal posterior nerve, or inferior alveolar nerve), the patients assessed their pain sensation via the visual analogue scale (VAS). They were asked about the occurrence of pain throughout the method. Lastly, the patients selected their choice between the two methods.
As found, the mean general pain experienced was more for the conventional anesthesia, and 1.95 (0.53 SD) for computerized anesthesia with statistical differences (p < 0.05), Table 1.
The mean and standard deviation of perceived pain is depicted in the following table:
SRP, scaling and root planning; RT1, restorative
treatment in lower molars; RT2, restorative treatment in upper incisors; EXT,
extraction of upper molars
A
majority of patients did not feel any pain during the course of the treatment.
In conclusion, 92.5% of the patients favored the electronic, computerized
anesthesia.
