Carcinoma Arising in the Background of Oral Submucous Fibrosis.

Introduction: Oral submucous fibrosis is a chronic debilitating condition with potential for malignant transformation. Squamous cell carcinoma arising from a background of oral submucous fibrosis presents clinically as a distinct disease due to different etiopathogenesis.

Methodology: This prospective case series describes thirty cases of oral squamous cell carcinoma (OSCC) alongside oral submucous fibrosis (OSF).

Expression of cyclooxygenase 2 in oral submucous fibrosis: An immunohistochemical pilot study.

Introduction: Oral submucous fibrosis (OSF) is associated with inflammatory changes in at least some stages of the disease. Prostaglandin is one of the main inflammatory mediators and its production is controlled by various enzymes such as cyclooxygenase (COX). The genetic and pharmacological data strongly indicate that COX-2 should be investigated as a potential target for the prevention and treatment of OSF.

Dentigerous cysts in four quadrants: a rare and first reported case.

The dentigerous cyst is a developmental odontogenic cyst which usually occurs in the second and third decade of life. Dentigerous cyst is one of the most prevalent types of odontogenic cysts associated with partially erupted, developing, or impacted teeth. The mandibular third molars have a high predictability followed by maxillary canines.

Implant placement in the atrophic posterior maxilla with sinus elevation without bone grafting: a 2-year prospective study.

Purpose: The purpose of this study was to evaluate changes in alveolar bone height after direct sinus elevation and simultaneous implant placement in the posterior edentulous maxilla.

Materials And Methods: A prospective clinical study was conducted of patients undergoing sinus elevation for implant placement in the posterior maxilla to replace missing teeth. Residual alveolar bone height was between 4 and 7.
