Single tooth anaesthesia: a new approach to the paediatric patient. A clinical experimental study

The objective of this study is to assess the efficacy of the STA Wand System with respect to pain and fear reduction in paediatric patients and by using the Single Tooth Anaesthesia (STA) technique.

Patients included children and teenagers between 6 and 17 years of age, who required the administration of local anaesthesia prior to expected treatments. Local anaesthesia was performed by means of the electronic STA Wand System (Milestone scientific., Inc.) adopting the Single Tooth Anaesthesia (STA) technique. Pre- and post-anaesthesia, the patients were asked to complete the Wong-Baker faces image scale and the provider filled in the Frankl Scale.

All treatments were completed successfully and no collaboration issues were recorded. Frankl's assessment showed that 91% of patients regarded dental experience positively. The efficacy of the computer-assisted anaesthesia was at 100% when treating primary teeth, and 70% for procedures on permanent teeth. Almost the totality of treated patients (94%) gave a positive evaluation after having tried the device with STA technique. Only 6% of the patients assessed the procedure negatively.

The STA technique allows for absence of anticipatory anxiety, absence of physical pain, no anaesthetic effects in the perioral tissues and a controllable, lower dosage of the anaesthetic liquid.
