297 - Use of Intraosseous Anesthesia among Pediatric Dentists

Purpose:

Intraosseous anesthesia provides rapid and profound anesthesia and may offer advantages over traditional techniques in pediatric dentistry, yet its clinical adoption varies. This study surveyed practicing pediatric dentists to evaluate knowledge, attitudes, and use of intraosseous anesthesia in clinical practice.

Methods:

A cross-sectional electronic survey was distributed to 6,591 active pediatric dentists, with an estimated response rate of approximately 20%, yielding 354 respondents. The survey assessed frequency of intraosseous anesthesia use, clinical indications, preferred delivery systems, perceived benefits and limitations, training experience, and reported complications. Descriptive statistics summarize responses. Chi-square and Wilcoxon rank-sum tests evaluated associations between training, years since residency, and practice setting with current use. A multivariable logistic regression model identified independent predictors of intraosseous anesthesia use.

Results:

Of 354 respondents, 211 (59.6%) reported current use of intraosseous anesthesia. The SleeperOne/Soan system was the most commonly used device (83.5% of users). Improved patient comfort (56.2%) and faster onset (50.0%) were the most frequently cited advantages. Formal training during residency was not significantly associated with current use (p = 0.373); however, years since residency (p = 0.009) and practice setting (p = 0.0001) were significantly associated with use. In multivariable analysis, dentists practicing more than 20 years post-residency had lower odds of use (p = 0.009), while private practice was associated with higher odds (p = 0.034) and federal health clinic practice with lower odds (p = 0.022).

Conclusion:

Intraosseous anesthesia is widely used among surveyed pediatric dentists, with the SleeperOne/Soan system predominating. Practice setting and years of experience, rather than formal residency training, appear to drive adoption. Addressing barriers of limited training and equipment cost may improve utilization, particularly in underserved and institutional settings.
