Local anaesthesia can often be unbearable for young patients and stressful for a dentist. A computer-controlled local anaesthesia system allows the delivery speed and pressure to be adjusted to the clinical situation, developmental, anatomical, and physiological tissue differences observed in children. Effective anaesthesia is achieved with a lower amount of analgesic reducing the risk of toxic or allergic reactions and minimizing discomfort and sensation of numbness after the treatment. It helps prevent unwanted self- injuries to the lips, cheeks, and tongue.
