Final answer:
Lateral periodontal cysts are not associated with vital teeth.
Step-by-step explanation:
The statement that lateral periodontal cysts are always associated with vital teeth is false. Lateral periodontal cysts are actually not associated with vital teeth. They typically occur near the roots of teeth that have undergone root canal treatment or have been extracted. These cysts are usually asymptomatic and can be detected through dental X-rays.
