associated with extracted teeth.
APICOECTOMY AND RETROGRADE FILLING AS PERIAPICAL GRANULOMA TREATMENT.
The histopathological study of the removed tissue showed a lesion covered by histiocytes with some neutrophils, macrophages, lymphocytes and plasma cells, showing compatibility with periapical granuloma wall (Figure 4).
Antrochoanal polyp derived from periapical granuloma
The radiological differential diagnosis of radicular cyst includes periapical granuloma
, surgical defect or periapical scar, periapical cemento-osseous dysplasia, Traumatic Bone Cyst.
1) Radiographically, a periapical cyst has an imaging appearance similar to that of a periapical granuloma.
T-helper cell type 17/regulatory Tcell immunoregulatory balance in human radicular cysts and periapical granulomas.
They are inflammatory in nature and usually arise within a periapical granuloma
relating to stimulation resulting from a necrotic tooth [ten Cate 1972; Main 1985; Nair 1998].
occurs due to host response to inflammation subsequent to infection of pulp tis sues.
Differential diagnosis with periapical granuloma
, radicular cyst or other pathologies is mandatory and necessitates tissue biopsy; as periapical presentations of the lesion may confuse a practitioner.
