BACKGROUND The radicular cyst is very common odontogenic cyst of the jaws, which is usually associated with a tooth with necrotic pulp. The cyst formation requires proliferation of the epithelial rest cells of Malassez present in the periodontal ligament. Proliferation of epithelial rest cells of Malassez is an essential event in the Pathogenesis of radicular cyst. The wall of the cyst contains...

A competitive enzyme linked immunosorbent assay (ELISA) method was used to measure the concentration of lactoferrin in fluids from 36 odontogenic keratocysts, 15 dentigerous cysts, and 30 radicular/residual cysts. Keratocyst fluids contained significantly higher concentrations of lactoferrin than fluids from the other two types of cyst (p less than 0.001); but the range of values obtained withi...

Objective: To assess the thickness and color of collagen fibres in various odontogenic cysts for its possible role in expansion. Study design: 49 cases of 4 types of odontogenic cysts and 5 normal mucosal tissues were selected as the study and the control group respectively. All slides were stained with both Hemotoxylin and Eosin and the picrosirius red stain. The thickness of collagen fibres w...

AIM To report a rare case of large radicular cyst-associated deciduous tooth and to discuss the importance of cone beam computed tomography (CBCT) in diagnosing the condition. BACKGROUND Radicular cyst is the most common cyst affecting the permanent teeth, but its occurrence in deciduous teeth is rare. Most of the radicular cysts are asymptomatic and are discovered accidentally when radiograp...

During the past decade, endodontists aave concluded that some periapical zysts heal with nonsurgical endodonLie therapy. This opinion is based primarily on two articles. In the first study, Bhaskar' reported that, of 2,308 periapical biopsy specimens, 68% were granulomas and 42% were radicular cysts. The majority of these lesions were submitted by endodontists, but the reason for surgery was no...

Synovial cysts are cystic lesions arising from the synovial membrane of diarthrodial joints. They may or may not be continuous with the joint space, and they are usually filled with a mucinous fluid. Clinically, the most frequent presentation is lower back pain without motor or sensory impairment [1 ]. Synovial cysts can present with more classic radicular symptoms, mimicking a herniated nucleu...
