| Abstract | ||
| The cyst is described as a pathological cavity lined fully or in parts by epthelium with fluid, semi-fluid, or gaseous contents that is not caused by pus accumulation (1, 2). Odontogenic cyst generally classified into inflammatory (radicular cyst also called periapical or dental cyst, Residual cyst, Paradental cyst) and developmental (Eruption cyst, Gingival cyst, Glandular odontogenic cyst, Odontogenic keratocyst, Lateral periodontal cyst, Dentigerous cyst, Orthkeratinizing odontogenic cyst ) (3, 4) . The lining epithelium of odontogenic cyst originate from residues of tooth forming tissues which includes (epithelial cell rest of serres, reduced enamel epithelium(REE), epithelial cell rest of malassez) (4) . The ERM at the root apex of the affected tooth proliferates due to the inflammation which increase the osmotic pressure leading to the cyst's enlargement(3) . Periapical cysts are the most prevalent cystic lesions of odontogenic cyst nearly 52% - 68% (5) however rarely seen on clinical diagnosis it often discovered by radiographs as clearly defined round or oval unilocular radiolucency with a radiopaque sclerotic border in the periapical region of the affected tooth(6, 7) . Histologically appear one to two thin cell layers of nonkeratinized stratified squamous epithelium related to inflammatory infiltrates and inflamed fibrous connective tissue.(8) . Treatment of periapical cyst ranged from conventional endodontic therapy to surgical treatment like apicoectomy, marsupialization, enucleation depending on the size and extension of the lesion and its relation to anatomical structures and the systemic condition of the patient, generally has good prognosis (9, 10). Radicular cysts classified into apical, lateral and residual based on the anatomical relationship to the root of the tooth, apical radicular cysts make up the largest percentage 75% and related to the apex of non-vital tooth while The lateral type is unusual and develops after the spread of the inflammation from the pulp via the lateral root canals into the lateral periodontium, in complete curettage of radicular cyst after extraction of the involved tooth may not trigger complications mostly result in residual cyst formation accounting for 20% (11) | ||
