Abstract
AIM: This prospective, randomised, parallel, controlled study was conducted firstly to compare the onset of local anaesthesia (LA) when using the conventional technique versus the Wand computer-controlled LA and secondly to assess the pain experience in children. METHOD:Thirty children were randomly allocated to the treatment group (Wand) or the control group (conventional). Lidocaine 2% with adrenaline (1:80,000) was given as a buccal infiltration. The onset of pulpal anaesthesia was tested using an analytic electric pulp tester (EPT). The pain experience during the LA was recorded using a modified visual analogue score (VAS). RESULTS:Median time for the onset of LA was 6.30 minutes for the control and 7.25 minutes for the Wand group. Mean pain experience score for the control group was 9.78% as opposed to 8.46% in the Wand group. Statistical analysis showed that there was no statistically significant difference in the onset of LA (p = 0.486) and the pain experience (p = 0.713) between the two groups. CONCLUSION: When placing a buccal infiltration on upper first permanent molars, the onset of LA and the pain experience was no different using the Wand and the conventional technique.
