Findings:

The UR1 is root filled with a small amount of extruded filling material inside the lesion. There is a well-defined, unilocular radiolucency measuring 12mm, extending from the UR1 apical region to the UR2 apex. The origin is probably from the apex of the UL1. The buccal cortex is expanded and perforated. The palatal cortex is eroded at the level of the oral opening of the nasopalatine canal. The lesion has not eroded the nasopalatine canal more superiorly. The appearance is that of a radicular cyst.
