Tooth Anatomy

Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Summary

This summary is machine-generated.

Patients with a history of stroke have a significantly higher prevalence of acute periapical abscesses (PAs). This increased risk is particularly notable in those with hemorrhagic stroke or cerebral infarction.

Oral health
Neurology
Public Health

Background:

Stroke survivors may face unique oral health challenges.
Periapical abscesses (PAs) are infections at the root of a tooth.
Understanding PA prevalence in stroke patients is crucial for targeted care.

Purpose of the Study:

To determine the prevalence of acute periapical abscesses (PAs) in patients with a history of stroke.
To analyze the association between stroke history and the occurrence of PAs.

Main Methods:

Retrieved integrated hospital patient data.
Searched diagnosis codes for PAs and stroke.
Calculated and statistically analyzed the odds ratio (OR) for PAs in post-stroke patients.

Main Results:

Acute PAs prevalence was 1.39% in stroke patients vs. 0.6% in the general population (OR=2.78, P<0.0001).
Prevalence was higher for hemorrhagic stroke (1.19%, OR=2.38) and cerebral infarction (1.55%, OR=3.11).
Even in cerebral infarction without hypertension, PA prevalence was elevated (0.87%, OR=1.75).

Conclusions:

Stroke patients exhibit a significantly higher prevalence of acute periapical abscesses.
Oral healthcare providers must consider this increased risk in patients with stroke history, including those with hemorrhagic stroke or cerebral infarction.
