Expression of CD 20 B-Lymphocyte in oral epithelial dysplasia and oral squamous cell carcinoma: A comparative immunohistochemistry study.

Background: As the progressive trends in the field of immunotherapy, it is very favourable to reconsider the role played by B lymphocytes in the tumor microenvironment. Both the protumorogenic and antitumorogenic responses have to be evaluated to formulate an effective immunotherapeutic protocol.

Aim And Objective: The study was primarily conducted to assess the qualitative expression of B lymphocytes in pretumorogenic (oral epithelial dysplasia) and tumorogenic environment (oral squamous cell carcinoma).

Reliability of palatal rugae patterns in individual identification.

Background: Dental identification plays a major role in mass disaster identification of human remains. Palatal rugae can be used as a substitute for a comparative method of identification.

Materials And Methods: The present cross-sectional study was done with 137 pre- and post-orthodontically treated casts of patients, which were divided into 50 cases each of extraction and nonextraction and 37 cases of palatal expansion involving both extraction and nonextraction.

Forensic odontology as a humanitarian tool.

Humanitarian forensic action is the application of skills of forensic science in a conflicts or disasters as a humanitarian action. Forensic odontologist promote forensic odontology and forensic science principles to caseworks with the purpose of preventing human right violation by human identification, age estimation and where ever dental evidence is involved. Forensic odontologist is involved in all phases of disaster victim identification.

Immunohistochemical study of α-smooth muscle actin expression in oral leukoplakia and oral squamous cell carcinoma.

Context: It is important to evaluate the role of stromal myofibroblasts (MFs) in carcinogenesis and also as a predictive marker for lymph node (LN) metastasis at the invasive front of oral squamous cell carcinoma (OSCC).

Aims: To demonstrate the expression of α-smooth muscle actin (α-SMA) by MFs in the tissues of oral leukoplakia (OL) with dysplasia and OSCC. To record and compare the distribution of MFs in OSCC with LN metastasis and without LN metastasis.

Odontogenic keratocyst arising in the maxillary sinus: A rare case report.

Odontogenic keratocyst is an aggressive cystic lesion and a common type of tooth derived cyst due to presence of odontogenic epithelial remnants in different regions of jaw. In majority of cases, it is located in mandibular posterior region. But it can also be found in the maxilla especially in the canine region.
