Dental electro-anaesthesia in children: a pilot study

Sixty-six children aged 10-17 years, with previous experience of local anaesthesia, had one or more restorations placed while using the Cedeta Mark 2 electronic dental anaesthesia system. A control group of 121 children were treated routinely using injected local anaesthetic. Following all treatment the patients used a 10 cm visual analogue scale to subjectively report the severity of any pain they had experienced. Eighteen (27%) of the study group required injection of local anaesthetic to complete the episode of treatment. The study group had significantly higher pain scores than the control group. It was concluded that further research is warranted to assess the application of this technique to special groups, but that it is not at present a substitute for local anaesthesia by injection in routine paediatric dental practice.
