Modified Cajal's trichrome stain in oral squamous cell carcinoma.

Background: Modified Cajal's trichrome stain (MCTS) is a good differential stain that allows one to visibly distinguish between connective tissue and epithelial elements with different tonalities of colour.

Aim: Our study aims to evaluate and analyse the effectiveness of oral squamous cell carcinoma (OSCC) using MCTS.

Materials And Methods: A study was conducted retrospectively with 30 tissue blocks embedded in paraffin from cases of OSCC that have been confirmed by histopathology.

Comparative study of conventional exfoliative cytology and centrifuged liquid-based cytology in oral leukoplakia and oral squamous cell carcinoma patients.

Background: This study aims to compare the efficacy between conventional exfoliative cytology (EC) and centrifuged liquid-based cytology (CLBC) in control, leukoplakia, and oral squamous cell carcinoma (OSCC) patients. Oral leukoplakia and oral cancer require an early definitive diagnosis for better prognostic outcome. Oral EC, a minimally invasive technique that involves the examination of desquamated cells from the tissue surfaces used as a method of early diagnosis.

Expression of HIF-1α and Nestin in oral squamous cell carcinoma and its association with vasculogenic mimicry.

Aim: To evaluate and correlate the expression of HIF1-α and Nestin in tumor center and periphery of nonmetastatic, and recurrent oral squamous cell carcinoma (OSCC) and its association with vasculogenic mimicry.

Materials And Methods: About 60 histopathological proven cases of OSCC with proper tumor center and periphery were collected. Among them 25 are nonmetastatic, 25 metastatic, and 10 recurrent cases of OSCC.

Age Estimation using Cephalometrics-A Cross-Sectional Study among Teenagers of Salem District, Tamil Nadu.

Background: Age estimation is important not only in identifying dead body of a person but also in living persons since there is an increasing rate of juvenile delinquencies recorded every year. To avoid foul play by age fabrication, legal age estimation becomes important. Facial growth alteration takes place in the jawbones as age advances which can be observed with lateral cephalometry.

Benign fibroushistiocytoma of the gingiva.

Benign fibroushistiocytoma is a benign connective tissue tumor rarely seen affecting the head and neck region. These tumors were believed to be of histiocytic origin as they are comprised of cells, which showed spindled morphology and cells with a round histiocytic appearance. The current concept consents that the lesional cells rather represent a fibroblastic differentiation.

Hyperplasia of the mandibular body: An anomaly in a developmental anomaly.

Hyperplasias of the mandible are usually seen in relation to the condyle or affecting one half of the mandible, such cases being described as hemimandibular hyperplasia or elongation. This article presents a rare case of hyperplasia of the right body of the mandible. The case being unique in that although being present from childhood did not cause any functional disturbances or any occlusal disharmony characteristically seen in such developmental anomalies.
