ABSTRACT Objectives: The aim of this research is to definethe X-rayeffect on oral bacteria found inpatients’ mouth. Methods: The mutation of bacterial cells was being determined through samples taken from the patient’s teeth before and after exposure to dental diagnostic X-ray. 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 Staphylococcus species, Gram-positive Streptococcus, and Gram Negative E. coli were isolated from contaminated dental in Erbil (16, 16 and 6 respectively). While, fifty percent isolated staphylococcus was resistant to all of the tested antibiotic (Vancomycin (VA), Carbencillin(C), CIP (Ciprodar), Amoxicillin(AX) and Tetracycline(Te), but converted to sensitive after using X-ray dental diagnoses (100%). Further results suggested flexibility of nuclear mutation of cultivated bacteria. The other half of Staph. remained sensitive after exposure to radiation. Similar, results got in isolated Strep. species excess (25%) when exposed to radiation. Respectively, isolated E. coli had a lower positive response (33.3%) to radiation exposure. It was higher in the case of CIP and C antibiotics, later AX and Te followed with VA antibiotic. It’s investigated the cell suspensions density did not lower, while a significant reduction in the viable counts (from 8x108 to 6x108 CFU/ml). 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.
