Immunoexperssion of cancer stem cell marker (CD44) in ameloblastoma.

Background: Ameloblastoma is the most frequently encountered benign, locally invasive tumor. Attempts to surgically resect the tumor often leave small islands of tumor, which later result in recurrence in 50%-90% of cases. This has raised questions regarding the tumor cell populations that are responsible for tumor growth and recurrence.

Classification of odontogenic cysts and tumors - Antecedents.

Pierre Paul Broca produced a monograph on tumor classification which also included the classification of odontogenic tumors (OTs). The terminology used to describe malignant epithelial OTs has varied since the World Health Organization published the initial consensus on the taxonomy of OTs. Minor changes were introduced in the second edition.

Comparison of Antimicrobial Efficacy of Triclosan- Containing, Herbal and Homeopathy Toothpastes- An Invitro Study.

Background: Use of antimicrobial agents is one of the important strategies to prevent oral diseases. These agents vary in their abilities to deliver preventive and therapeutic benefits.

Objectives: This invitro study was conducted to assess antimicrobial efficacy of different toothpastes against various oral pathogens.

Myofibroma of the gingiva: a rare case report and literature review.

Myofibromas are benign uncommon fibroblastic tumors of the soft tissue, bone, or internal organs affecting all ages. These lesions histopathologically may mimic many other soft tissue tumors of the oral cavity such as spindle cell tumors of neurogenic and smooth muscle cell origin, thus leading to misdiagnosis and mistreatment. This case report describes a rare benign tumor, which presented as a soft tissue swelling on posterior gingiva.

Hand schuller christian disease: a rare case report with oral manifestation.

Langerhan's Cell Histiocytosis (LCH) is disorders which include abnormalities that result from abnormal proliferation of langerhan's cells or their precursors. LCH is clinically classified into three types-eosinophilic granuloma, Hand Schuller Christian disease and Abt-Letterer- Siwe disease. It is usually manifested in childhood as well as in adulthood.

Taxonomy of salivary gland neoplasm.

Classification of neoplasms of any organ should be predicted on the patterns of differentiation that reflect the organization and cell types of the parental tissue. The ability to classify a neoplasm instills confidence in its predicted biologic behavior and the selection of treatment. There has not been a single universally used classification system for salivary gland tumor.

Immunohistochemical Expression of PCNA in Epithelial Linings of Selected Odontogenic Lesions.

Aim: Though odontogenic lesions have in common origin from the primitive odontogenic epithelium , there is a diversity in their initiation behavior and growth. The aggressive nature of odontogenic keratocyst similar to ameloblastoma in comparision with the other common odontogenic (dentigerous and radicular) cyst could be due to possible differences in their epithelial linings. PCNA (Proliferating cell nuclear antigen) is a cell cycle related antigen, used in the study of cell kinetics of these epithelial linings, to corelate the biological behaviour among these common odontogenic lesions.

A Non-Invasive Technique which Demonstrates the Iron in the Buccal Mucosa of Sickle Cell Anaemia and Thalassaemia Patients who Undergo Repeated Blood Transfusions.

Background: Iron is vital for all the living organisms. However, excess iron is hazardous because it produces free radical formation. Therefore, the iron absorption is carefully regulated to maintain an equilibrium between the absorption and the body loss of iron.
