Salivary Oxidative Status in Relation to Periodontal Status among Workers in Diagnostic Radiation Field

Background: Workers in diagnostic radiation field are at higher risk for systemic diseases as well as oral diseases like periodontal diseases. The aim of this study was to estimate the salivary oxidative stress marker and salivary antioxidants and their relation to periodontal status among a group of diagnostic radiation workers. Material and methods: The sample for this study included a study group which consisted of 40 men working in the diagnostic radiation field and a control group which consisted of 40 men-working as nurses or at a laboratory in Baghdad hospitals all of them aged 30-40 years. Collection of unstimulated salivary samples was carried out under standardized conditions. The salivary flow rate was measured, and then salivary analysis was done to determine the level of salivary antioxidants (zinc, copper, and manganese) and oxidative stress marker (protein carbonyl). Gingival, periodontal pocket depth and clinical attachment loss indices were used for recording the periodontal status. Results: Data analysis of the present study reported that salivary protein carbonyl, copper, and manganese were higher among radiographers than the control group with a statistically highly significant difference (p<0.01), while salivary zinc and salivary flow rate were lower among radiographers than the control group with a statistically highly significant difference (p<0.01). The gingival index was higher among radiographers although it was not significant statistically (p>0.01), periodontal pocket depth and clinical attachment loss were higher among radiographers than the control group with a statistically highly significant difference (p<0.01). Conclusions: Ionizing radiation affects salivary antioxidant, oxidative stress marker (protein carbonyl) and salivary flow rate and these in turn will affect periodontal status.
