213 - Utilization of Intraosseus versus Traditional Local Anesthesia Methods

Abstract:

Purpose: The aim of this retrospective study is to evaluate and compare the technique and patient behavior during local anesthesia (LA) delivery of the Soan computer-controlled delivery system to traditional needle and syringe delivery.

Methods: Retrospective study ranging from January 2024 through June 2025 with patients of the UTH Houston graduate pediatric dental clinics who received local anesthetic looking at sex, age, health status, medication, prior dental history, prior sedation history, radiographic severity, teeth involved, arch involved, failed treatment, supplemental anesthesia needs, treatment type, use of nitrous, appointment and treatment Frankl scores. Patient who were only seen for treatment for emergencies, moderate sedation or general anesthesia were excluded. Student t tests, Fisher exact tests and chi-square analysis completed, with p-values less than 0.05 considered significant.

Results: 215 children [Age-Mean(SD)=12.2(3.63); Female=54.0%] were identified and evaluated, totaling 315 appointments and 574 teeth. Significant differences based on local anesthesia delivery method usage were noted based on restorative treatment (P=.019), if patient were F4 at exam and behaviour changed (P=0.025), LA choice (P < 0.001), and way delivered (P < .001). Anxiety noted at injection in patient notes was only noted with traditional needle and syringe but was not noted as statistically significant (P >.05). No significant differences noted between any other factors extracted from the notes, including patient behavior (P >.05).

Conclusion: Soan was more likely to be used by providers for treatment on primary molars, treatment involving SSCs, and treatment with septocaine, demonstrating that Soan is comparable to traditional methods in utilization and managing patient behavior.
