Are lateral periodontal cysts always associated with a vital tooth?

Lateral periodontal cysts are typically associated with a vital, or living, tooth. This is because these cysts are often found near the roots of teeth that are still functioning. Therefore, the other option, B, is incorrect. Additionally, cysts that are not located near vital teeth may be a sign of a more serious condition and should be promptly evaluated by a dentist or oral health professional.
