Background: An (OPG) popular radiograph used to identify the hard tissues of the oral cavity and adjacent skeletal structures is an orthopantomogram (OPG). It’s an extra-oral radiograph that approximates the mandible’s focal trough Although the resolution is not as fine as intra-oral radiographs for tooth examination.
Aims: Health effects of exposure to diagnostic X-ray on Oral Bacterial after (OPG) Examination.
Methods: The mutation of bacterial cells was being determined through samples taken from the patient’s teeth before and after OPG exposure in Tishik International University faculty of Dentistry.
Results: Microbial growth cells when sticks to each other define as a biofilm and often on a surface. The cells within the biofilm are composed of polymeric substances and embedded in a slimy extracellular matrix. These extracellular polymeric substances produced by the cells are typically a polymeric conglomeration of polysaccharides, extracellular proteins, and DNA. Our results of prescreening the referenced patients included Grampositive streptococcus, staphylococcus, lactococcus, granulicatella , Erysipelothrix, kocuria, Gemella and Rothia. That means using diagnosis X-ray exposure may be affected the viability of total oral bacterial and the Gram-positive bacteria seem to imply higher mutant than gram-negative bacteria.
Conclusion: Results of the examination reasoned that the dental diagnoses utilizing X-Ray display ought to influence viability entire oral bacterial and Gram-positive bacteria show to infer more mutant than Gram-negative bacteria.
