Estimation of salivary and serum CYFRA 21-1 levels in patients with oral squamous cell carcinoma.

Background: Cytokeratins are the largest sub-group of intermediate filaments and represent the most abundant proteins in epithelial cells. CYFRA 21-1 (human cytokeratin fragment antigen 21-1) is a soluble fragment of cytokeratin 19 known to increase in various malignancies.

Aim: The present study is aimed to estimate salivary and serum levels of CYFRA 21-1 in oral squamous cell carcinoma (OSCC) patients and to compare them with healthy controls.

Calretinin expression in odontogenic cysts and odontogenic tumors and the possible role of calretinin in pathogenesis of ameloblastoma.

Introduction: Histopathological diagnosis of odontogenic cysts and tumors is a task mostly accomplished with hematoxylin and eosin staining. However, the use of additional diagnostic modalities such as immunohistochemistry may be necessary in histologically similar lesions. The reports of studies which have used calretinin as an immunohistochemical marker for ameloblastoma have been conflicting.

Hemangiomatous ameloblastoma: Case report with a brief review.

Ameloblastoma is a benign epithelial odontogenic tumor with many histological variants. Hemangiomatous ameloblastoma (HA) is a very rare variant which shows unique histopathological features varying from conventional ameloblastoma. We present a case of a 35-year-old female patient with a swelling over right lower back region of jaw, showing mixed radiolucent-opacity.

An Endocrine Jaw Lesion: Dentist Perspective in Diagnosis.

Brown tumor is a rare nonneoplastic focal giant cell lesion that occurs in hyperparathyroidism patients with a prevalence rate of 0.1% in jaws. We report an extremely rare case of brown tumor in mandible of a 40-year-old female patient that presented as the first clinical manifestation of hyperparathyroidism.

Evaluation of Vinegar as a Disinfectant for Extracted Human Teeth - An in-Vitro Study.

Introduction: In dentistry, extracted human teeth are routinely used to learn technical and preclinical skills. Since human teeth harbour many pathogens these should be disinfected before use to minimize the risk of infections. Some commonly used disinfectants in laboratories are 10% formalin, 3% hydrogen peroxide (H2O2), 5.

Ectopic compound odontoma in the buccal mucosa: report of a rare case.

Eruption of tooth into extraosseous locations is an extremely rare condition. We report a case of a six-year-old girl child with tooth-like structure erupting from the right buccal mucosa. Clinical, radiographic, and histopathologic examination suggested the diagnosis of compound odontoma.
