Effectiveness of Er:YAG Pulse Therapy for Achieving Pre-emptive Dental Analgesia in Children

"Water mist spray set to maximum, non-contact handpiece with sapphire tip. Tip-to-tissue distance 10 mm from the tooth neck, achieved by using a spacer. Energy is delivered to the enamel above the gingival margin adjacent to the cemento-enamel junction (perpendicularly towards the dental pulp) on each of the four line angles of the tooth for 30s, moving the laser handpiece in a sweeping action. Pulse energy - 0.2 W/ 10 Hz/ 20 mJ. Follows increase of energy and repetition of protocol - 0.6 W/ 15 Hz/ 40 mJ. Total duration of LA-induction - 240s."

Performing imitation of laser analgesic procedure. No pulse energy applied, non-contact handpiece with sapphire tip. Moving the laser handpiece in a sweeping action towards the cemento-enamel junction (pointing perpendicularly towards the dental pulp) on each of the four line angles of the tooth. Total duration of placebo analgesia induction - 240s.
