A conservative biopsy technique for periapical lesions

This paper presented a conservative technique for biopsy of periapical lesions. The case report demonstrated the insertion of a flexible microsurgical biopsy forceps through a labial sinus tract into a lesion for removal of specimens for histopathological evaluation. This limited tissue removal seemed to induce a change from a cyst to a granuloma, as well as stimulate a degree of repair.
