Identification of Specific Anaerobic Bacteria in Endodontic Infections of Primary Teeth-A PCR Study.

Introduction: Invasion of microorganisms and their multiplication in root canals (RCs) results in endodontic infections of primary teeth. Acute and chronic inflammation may be present in the periapical area and are based on the amount and virulence of microorganisms, especially anaerobic bacteria present in the RC. To identify microorganisms very precisely in endodontic infections, polymerase chain reaction (PCR) is used.

Genotoxic effects of X-rays in buccal mucosal cells in children subjected to dental radiographs.

Objectives/aims: Bitewing and digital dental panoramic radiographs have become important adjuvants for successful dental practice in pediatric dentistry. Both methods lead to genetic changes in the oral buccal epithelium that have not yet been satisfactorily explored. The aim of the present study was to evaluate the genotoxic effects induced by X-ray radiation from bitewing and panoramic dental radiography in exfoliated buccal epithelial cells of children, using the Buccal Micronucleus Cytome assay.
