Advanced periodontitis or toothlessness in stroke patients is linked to more severe neurological deficits upon admission. This condition independently predicts greater initial stroke severity, though it doesn't impact long-term outcomes.
Area of Science:
- Neurology
- Periodontology
- Public Health
Background:
- Periodontitis is a known risk factor for ischemic stroke.
- The impact of severe periodontitis or edentulousness on stroke severity remains under-investigated.
Purpose of the Study:
- To investigate the association between advanced periodontitis/edentulousness and neurological deficit on admission.
- To assess the relationship between advanced periodontitis/edentulousness and short-term stroke outcomes.
Main Methods:
- 169 ischemic stroke patients were analyzed.
- Neurological deficit was measured using the NIH Stroke Scale (NIHSS).
- Clinical attachment level (CAL) ≥6mm defined advanced periodontitis.
Main Results:
- Patients with advanced periodontitis/edentulousness were older and had higher NIHSS scores on admission.
- Advanced periodontitis or edentulousness was an independent predictor of greater NIHSS on admission.
- Stroke severity on admission, not periodontitis, influenced patient outcomes.
Conclusions:
- Advanced periodontitis or edentulousness is associated with increased neurological deficit upon admission in ischemic stroke patients.
