Abstract


Pain is one of the main reasons that bring patients to the dental office, but at the same time fear of the pain is the chief reason that keeps them away. Needle-less jet injection device has been proposed by which a high-velocity spray of anesthetic solution is forced under high pressure into the oral mucosa, leading to mechanical infiltration of the compound

Aim and objectives: To clinically evaluate the efficacy of needle-less jet injector using 2% Lidocaine with 1:80,000 epinephrine as anesthetic solution and to compare the jet injection with the standard conventional needle injection technique.

Materials and Methods: 27 patients including 108 dental extractions were anaesthetized by needle-less jet injector and conventional needle infiltration technique. Pain during administration of anesthetic solution and during dental extraction was evaluated using Wong Baker Faces Pain Rating scale, VAS scale line and VAS numeric pain rating scale. The time of onset of soft tissue anesthesia and depth of infiltration anesthesia were evaluated and patient acceptance was evaluated.

Results: Pain during administration of anaesthesia was significantly less using needle-less jet injector than conventional infiltration (p=0.0001) and there was no significant difference in pain during dental extraction. The success rate of needleless injectors was 92.59% in maxilla and 85.18% in mandible. Overall 77.78% of patients preferred jet injectors over conventional infiltration technique.

Conclusion: Needle-less jet injector was proved to be less painful during administration of anaesthetic solution, similarly efficacious and more preferred as compared to conventional needle infiltration.
