The results of this study show that both C-CLAD injection systems (The STA Wand® and Dentapen®) yield similar outcomes in terms of pain perception during palatal injections.
Dentapen® is a wireless device and does not need specific consumables, since standard dental needles can be used.
STA Wand® consists of three elements: a disposable handpiece, a computer control unit, and a foot pedal (not shown). The study concludes that another inconvenience of the STA Wand ® is the economic cost of the consumables.
