Cytogenetic study of dental diagnostic x-ray workers
Keywords:
X-rays, chromosomal changes, ionizing radiation, X-ray techniciansAbstract
Background and Objectives: studying chromosome changes for dental x-ray workers in the city of kut and diagnosing those abnormalities resulting from continuous exposure to radiation. Exposure and Methods: The chromosomes of those exposed to dental X-rays were analyzed and studied using cytogenetic analysis to detect chromosomal aberrations caused by ionizing radiation after collecting blood samples from those exposed to Al-Zahraa and Al-Karama Teaching Hospital as well as from the Taiba Specialized Center in addition to the dental clinics in Wasit. Results: Chromosomal analysis of all subjects showed chromosomal aberrations, and most of the aberrations were structural changes that were divided according to the ratio of their frequencies. The largest percentage was for the gap chromosome type (44%), chromosomal-aberration dicentric (16%) and chromosomal-aberration gab and dicentric (8%). Conclusion: Dental diagnostic x-rays have an effect on the chromosomes of workers exposed to a long-term cumulative exposure period, as it leads to the appearance of aberrations of the type chromosomal aberration (gab chromatid ) is the most frequent in this stuy.
