Periapical disease in post-stroke patients.

PURPOSE
To assess the prevalence of acute periapical abscesses (PAs) in patients with history of stroke.


METHODS
Integrated data of hospital patients was used. Data from the corresponding diagnosis codes for PAs and stroke were retrieved by searching the appropriate query in the database. The odds ratio (OR) of acute PAs and its association with post-stroke conditions was calculated and analyzed statistically.


RESULTS
The prevalence of acute PAs in patients with stroke history was 1.39% as compared to 0.6% in the general patient population of the hospital. The OR was 2.78 and the difference was statistically significant (P< 0.0001). The prevalence of acute PAs in patients with a history of hemorrhagic stroke was 1.19% and the OR was 2.38. The difference was statistically significant (P< 0.0001). The prevalence of acute PAs in patients with a history of cerebral infarction was 1.55% and the OR was 3.11. The difference was statistically significant (P< 0.0001). The prevalence of acute PAs in patients with a history of cerebral infarction without hypertension was 0.87% and the OR was 1.75. The difference was statistically significant (P< 0.0001).


CLINICAL SIGNIFICANCE
Oral healthcare providers should be aware of the possible higher prevalence of periapical abscesses in post-stroke patients. This can include patients with a history of hemorrhagic stroke or cerebral infarction.
