Abstract

Aim: The objective of the current study was to assess the injection pain and intraoperative pain of the needle-less jet injector in comparison to the conventional needle-attached syringe as infiltration local anesthesia during pulpotomy.
Subjects and methods: Fifty-six vital deeply carious maxillary first primary molars indicated for pulpotomy were randomly assigned into two equal groups (N=28), where group I received maxillary infiltration anesthesia using the needle-less jet injector and group II received anesthesia using a conventional needle-attached syringe followed by pulpotomy and restored with stainless steel crown. Evaluation of pain was performed during injection, pulpotomy, and crown preparation using the Face Pain Scale-Revised (FPSR) and Sound, Eye, and Motor (SEM) Scale.
Results: The Evaluation of pain scores using FPS-R and SEM Scale during injection, and pulpotomy showed no significant differences between both groups. Regarding crown preparation, pain scores using the SEM scale showed a significant difference between both groups, whereas FPS-R showed no significant differences. Besides, no correlation was detected between pain scores and age or gender.
Conclusions: In primary teeth, the needle-less jet injector was successful in anesthetizing the maxillary first primary molars during the pulpotomy and crown preparation procedures.
