Case 11

Radiographic Findings

  • ==Modality: OPG.==
  • ==Location: There is a lucency in the anterior maxilla between teeth 12 and 21 (specifically around the 11 and 21 region).==
  • ==Description:==
    • ==It is a corticated lesion.==
    • The color is uniform/consistent.
    • ==It has a teardrop shape.==
    • ==It is not a closed, unilocular cystic lesion; rather, it is continuous with and involves the incisive canal.==

Differential Diagnosis

  • ==Nasopalatine Duct Cyst: The findings are consistent with this diagnosis due to the involvement of the incisive canal and the characteristic teardrop shape.==
  • ==Radicular Cyst:==
    • Distinguished from a nasopalatine cyst because a radicular cyst would appear as a closed, unilocular lesion.
    • A radicular cyst is associated with a non-vital tooth.

Investigations

  • ==Vitality Testing: This should be performed on the associated teeth (11, 21) to exclude a radicular cyst. If the teeth are vital, it supports a diagnosis of a nasopalatine cyst rather than a radicular cyst.==
