BACKGROUND Apical periodontitis includes periapical granulomas and radicular cysts, which are histologically distinguished by the absence and the presence of an epithelial lining, respectively. The main cause of apical periodontitis is the bacterial colonization of the root canal space. This research aimed at assessing whether and how periapical granulomas and radicular cysts differ in terms of...

Introduction: Odontogenic cysts are characterized by an expansile non–infiltrative growth through several mechanisms which include presence of mast cells in the capsule. The mast cells can be demonstrated histochemically as well as immunohistochemically. Aim and Objectives: The primary objective of the study was to analyze the presence and distribution of mast cells in radicular cyst, dentigero...

A 43-year-old man presented with a nontraumatic orthostatic headache, spatial disorientation, and visual hallucinations ("colored flames"). General and neurologic examination were normal. Turbo spin echo T2-weighted MRI showed bilateral subdural fluid collection and venous sinus engorgement (figure, A), suggesting spontaneous intracranial hypotension (SIH). Two subdural hematomas were also foun...

Radicular cyst is one of the late sequelae of untreated pulpal necrosis often caused by dental trauma and caries. It develops slowly and gradually but symptomlessly, and involves many adjacent sound teeth endangering their vitality and even prognosis.The objectives of this study were to determine the site, age and sex distribution as well as to know the ratio of trauma to caries in the occurren...

Radicular cysts are the most common inflammatory odontogenic cystic lesions. It originates from epithelial residues in periodontal ligaments secondary to inflammation. The pathogenesis involves the activation of epithelial cell rests of Malaseez after physical, chemical or bacterial injury. Microscopically, the cyst is thin with smooth or corrugated inner surface. The most common epithelial lin...

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...

Enterogenous cysts mostly present in the cervical and thoracic region of the spinal canal and have only rarely been observed in the lumbar region. We report here a case of a recurrent enterogenous cyst in the lumbar spinal canal. A 24-year old woman presented with lower back and left radicular leg pain for 1 year. She had been operated on for mass lesion at the same level 10 years ago. Lumbar s...

Introduction: Cysts of the jaw are a recognized clinical entity for a long time and are a benign bone destroying lesion. Their remains a diagnostic ambiguity between cysts and cyst-like lesions of the jaws. Objective: The main objective of this study was to assess the total soluble protein content in fluid aspirates of intra osseous cyst of maxilla and mandible. Materials and Methods: A total n...

Objectives: The aim of this case report is to describe radiographically the specific features periapical cysts differentiate them from dentigerous cyst lesions despite their similar clinical appearance.
 Case Report: A 21-year-old female patient came Dental Hospital in Bandung with a referral for cone-beam computed tomography (CBCT) examination diagnosis suspected right mandibular and left...

OBJECTIVE Cystic ameloblastoma, keratocystic odontogenic tumor, dentigerous cyst, and radicular cyst are the most commonly encountered cystic odontogenic lesions. The aim of this study was to investigate the expressions of survivin, E-cadherin, CD138, and CD38 in these lesions and their potential diagnostic usage. MATERIAL AND METHOD A total of 20 cases, consisting 5 radicular cysts, 5 dentig...
