Assessing Genotoxicity and Cytotoxicity Induced by X-Ray Exposure From Cone Beam Computed Tomography at Varied Fields of View.

Introduction: The practice of dentistry benefits greatly from cone beam computed tomography (CBCT) and advantages should be prioritized over hazards; even modest doses of X-rays have the potential to have cytotoxic effects, damage DNA through their clastogenic impact, and stimulate the creation of micronuclei along with further nuclear changes.

Aims And Objectives: To assess the genotoxicity and cytotoxicity of X-rays in exfoliated oral mucosal cells from patients who underwent CBCT scans at different fields of view (FOV), and to examine and assess the extent of cytotoxicity and genotoxicity caused by X-rays in oral exfoliated cells of people who were subjected to CBCT at different fields of view (FOV).

Material And Methods: Following CBCT exposure, 66 patients were chosen from the Department of Oral Medicine and Radiology at the SVS Institute of Dental Sciences, Mahbubnagar.

Pemphigus vulgaris: a case report.

Pemphigus vulgaris (PV) is an autoimmune mucocutaneous disorder of the oral cavity and is the most common subtype of pemphigus. The etiology remains obscure, although the disease is characterized by autoantibodies directed against the desmoglein component of the keratinocytes. It manifests clinically as vesicle, bullae or erosions of skin and mucous membrane and histopathologically shows the presence of acantholysis.

Erythema multiforme: integrating the superfluous diagnosis to a veracious conclusion (case report).

Erythema multiforme (EM) is an acute, self-limiting hypersensitivity reaction that ranges from a mild cutaneous, exanthematous variant with minimal oral involvement to a progressive fulminating severe variant with extensive mucocutaneous epithelial necrosis (SJS & TEN). Knowing the etiological spectrum is the key for management in EM where sometimes leads to mortality. There are no specific diagnostic tests for EM, diagnosis is mainly clinically supported.
