Abstract

This study was designed to investigate the characteristics of oral conditions of workers in a radiation field. The study was carried out on male subjects with ages ranging from 25-45 years and working in the National Center for Research and Radiation Technology (NCRRT), under protective measures and subjected to long-term low dose ionizing radiation. The subjects were divided into four groups; the first three groups represented the study groups, including subjects working in the radiation field; and a fourth group, the control group, including subjects working away from the radiation field. Study groups were divided according to the duration of work into the first group (including 20 subjects working for at least 10 years), the second group (including 20 subjects working from 5-10 years and the third group (including subjects working for at least five years). The investigation in bothstudy and control groups was made via immunological assessment by determination of the level of secretory immunoglobulin A (SIgA), microbiological assessment via detection of aerobic, anaerobic bacteria and Candida albicans and by dental assessment through determination of dental indices (Decayed Missed –Filled (DMF) index, periodontal index and Plaque index). The results of this study reported lower level of SIgA in study groups compared to controls and the presence of Actinobacillus-actinomycetemcomitans, Fusobacterium and Bacteriod Forythus in study groups. There was a significant difference between the study and control groups regarding DMF index, periodontal index and Plague index, in addition to the negative correlation between SIgA and the dental índices. This study showed that workers in the radiation hall NCRRT, subjected to long-term low dose ionizing radiation, were found to be at higher risk of carying and periodontal diseases compared to the control group.
