Periodontal Health Status and Antioxidant Levels Among a Group of Diesel Generator Workers
Background: The highly use of generators creating an alarming level of pollution (air and noise) in all regions of the world. One of the dangerous pollutant that emitted into environment during combustion process of diesel engines is The soot which is impure carbon particles known for their direct and broad impact on the respiratory organs and some polycyclic aromatic hydrocarbons which responsible for their cancer properties are associated with it. As Environmental conditions have many serious impacts on the general health of humans, it has also on oral status.
Aim: The aim of the study was to evaluate periodontal health status, salivary antioxidants (catalase, total antioxidant capacity and zinc) and protein carbonyl as oxidative stress marker in relation to periodontal disease among a group of diesel generator workers.
Materials and methods: The sample for this study included 94 workers in diesel generators, their ages were between 20 and 49 years. Collection of stimulated salivary samples was carried out under standardized conditions to determine the levels of antioxidants by using spectrophotometer while protein carbonyl by ELLISA technique, and periodontal health was determined by the CPI that modified by WHO in 1997.
Results: The result revealed that exposure of healthy subjects to occupational hazards for long period produces different changes in the oxidative stress markers as revealed by excessive production of the protein carbonyl (PC) and depletion in the activity of catalase (CAT) as antioxidant, according periodontal health : all categories of CPI approximately inclined within duration, and the most predominant score recorded is the score 2(calculus) and score 1 (bleeding) respectively with following mean ± SE (1.83 ± 0.15) and (1.81± 0.16) followed by score 3(shallow pocket) (1.74 ± 0.16) then score 4 (0.319 ± 0.06) while the least one was the score 0 or healthy (0.298 ± 0.08).
Conclusion: the work duration in diesel generator field affect the oxidative status and oral health condition of workers in that field, So, the workers in generators need special preventive programs to be designed for them.
