The nevoid basal cell carcinoma syndrome is caused by a mutation of which gene?
Patched (PTCH) gene
The most common location for the lateral periodontal cyst is:
mandibular bicuspid area
By definition, a dentigerous cyst must occur:
in association with the crown of an unerupted tooth.
The lateral periodontal cyst is most closely related to what other odontogenic cyst?
Gingival cyst of the adult
The botryoid variant of the lateral periodontal cyst got its name because:
The botryoid variant of the lateral periodontal cyst got its name because:
The most so-called primordial cysts are microscopically diagnosed as:
odontogenic keratocysts.
The most common site for the glandular odontogenic cyst is:
anterior mandible.
