The bevel effect: a prospective, randomized investigation into needle design in dental intraligamentary anesthesia

ConclusionsThe short triple facet-designed bevel demonstrated significantly less mechanical deformation, suggesting potential advantages in maintaining needle lumen patency.Clinical relevanceThe intraligamentary needle bevel design is linked to mechanical deformation and anesthetic success after repetitive use, but not to puncture pain.
