Abstract
Radiolucent lesions in anterior maxillary midline are periapical cyst and granuloma, an inflammatory processes result from periodontitis or pulpal disease. These lytic lesions appear as lucencies with regular border in pariapical or interradicular area of teeth. The second step for the lesions involve this specific area are commonly nasopalatin duct cysts. Nasopalatine duct cyst is developmental non-odontogenic cyst that arise from cystic proliferation of epithelial remnant in incisive canal. Also, this lesion shows round, ovoid or heart-shaped radiolucency. Although the lesions mentioned above are common for this area, but we should differentiate them from the other uncommon lesions that may occur in anterior maxillary midline. Differential diagnosis for these radiolucencies are large incisive canal, odontogenic keratocyst, central giant cell granuloma, calcifying odontogenic cyst and other rarity. Here, we demonstrate a case with radiolucent lesion in anterior maxillary midline but the diagnosis is one of the rarity in this area.
