Correct answer: DNasopalatine duct cyst

The nasopalatine duct cyst is the most common non-odontogenic cyst of the jaws. It develops from epithelial remnants associated with the nasopalatine duct and usually appears as a well-defined round, ovoid or heart-shaped radiolucency in the anterior maxillary midline, between or above the central incisor roots. The adjacent incisors are usually vital. A nasolabial cyst is an extraosseous soft-tissue cyst of the nasolabial region. Surgical ciliated cysts are uncommon acquired lesions, usually following surgery or trauma involving respiratory epithelium. Intraosseous epidermoid cysts are rare. A Stafne bone cavity is not a true epithelial-lined cyst but a developmental lingual mandibular bone depression, usually containing salivary tissue.
