Quizplus · Accepted Answer

A follicular cyst, also called a dentigerous cyst, appears in the bone in this radiograph surrounding a fully formed crown of an unerupted premolar. An eruption cyst is similar to a follicular cyst but is found in the soft tissue around the crown of an erupting tooth. A lateral periodontal cyst is seen most often in the mandibular cuspid and premolar area. It presents as an asymptomatic, unilocular or multilocular radiolucent lesion located on the lateral aspect of a tooth root. A primordial cyst develops in place of a tooth.
