Abstract

Objectives

We aimed to evaluate the association between antibiotic prophylaxis and adverse outcomes following tooth extraction within the Veterans Affairs Healthcare System.

Methods

We conducted a retrospective cohort study of patients undergoing dental extractions in 2015–2019. The primary exposure was antibiotic prophylaxis. The primary outcome was post-extraction complication within 7 days (e.g., alveolar osteitis and surgical site infection); the secondary outcome was subsequent medical care relating to a post-extraction oral complication within 7 days. Multivariable logistic regression models assessed the independent effect of antibiotic prophylaxis on each outcome.

Results

Of 385,880 visits with a dental extraction, 122,810 (31.8%) received antibiotic prophylaxis. Overall, 3387 (0.9%) experienced a post-extraction complication and 350 (0.09%) received medical care relating to a post-extraction oral complication within 7 days. In multivariable regression, diabetes was a statistically significant (p = 0.01) effect modifier of the association between antibiotic prophylaxis and post-extraction complication. Among visits for patients without diabetes, antibiotic prophylaxis was significantly associated with an increased odds of post-extraction complication (odds ratio [OR] = 1.25, 95% confidence interval [CI]: 1.13–1.38), but among visits for patients with diabetes no significant effect was observed (OR = 1.03, 95% CI: 0.92–1.15). Antibiotic prophylaxis was not significantly associated with post-extraction medical care (OR = 1.04; 95% CI: 0.83–1.30).

Conclusions

In this large retrospective cohort, we observed no significant protective effect of antibiotic prophylaxis on post-extraction complications or subsequent medical care utilization in a setting with low complication rates. These data suggest that use of antibiotic prophylaxis in similar settings may need to be re-evaluated to minimize unnecessary antibiotic use.
