The Influence of Cigarette Smoking on Various Aspects of Periodontal Health

Tobacco is one of the most important risk factors for oral diseases, including oral cancer, oral mucosal lesions and periodontal diseases. There is substantial evidence suggesting that the risk of oral diseases increases with frequent use of tobacco and that quitting smoking results in reduced risk. In this article, the influence of cigarette smoking on the periodontium will be discussed, giving importance to the effects on immune responses, alveolar bone loss, periodontal pathogens and briefly outlining the negative effects of smoking on wound healing and periodontal treatment procedures

Health Risk of Occupational Exposure in Welding Processes I. Genotoxic Risk

The welding processes belong among the important sources of occupational pollutions. The welding fumes are ranked, according to the classification of IARC (International Agency for Research on Cancer), into the group of 2B. In our study we have performed the investigation of twenty men (exposed group) working in the stainless steel welding industrial processes (11 welders and 9 grinders, average age was 31 years, 55 % of smokers, average time period of welding occupational exposure was 8 years). The concentrations of chromium (0.557–16.343 mg/m3) and nickel (0.340–10.129 mg/m3) in occupational atmosphere highly exceeded established values of maximum permitted concentrations (0.1 and 1.0 mg/m3, respectively). The concentrations of manganese did not exceed its permitted values. Total concentrations of 12 polycyclic aromatic hydrocarbons (PAH) in occupational atmosphere varied from 300.9 to 961.2 ng/m3. For purposes of biological monitoring, the levels of chromosomal aberrations were determined in the exposed and control group. Healthy blood donors servedas a control group. People from that group were not occupationally exposed to harmful chemical compounds (20 men, average age was 36 years, 40 % of smokers). Increased level of chromosomal aberrations of exposed group brought the evidence about higher genotoxic risk of investigated welding processes

Occupational Mental Stress Assessment of Elementary School Teachers and Firefighters – Rescuers

The presented study aims to compare occupational stress of 50 teachers and 56 firefighters. Both these groups are laden with high exposure to work-related stress. For assessing the occupational load the Meister questionnaire was used. We found that teachers percieved their occupational stress worse than firefighters and reached the 2nd degree of load. They complained mostly about the factor of overload and factors of the stress reactions – fatigue, mental overload and unacceptability to perform pedagogical work in the same intensity for a long time. Firefighters achieved better results (1st degree of load), even better than the population norm. An explanation may be found in the fact that firefighters represent a selected population of emotionally, psychically and physically resistant individuals

Influence of Profession on Teachers’ Quality of Life

The aim of this study was to analyze the quality of life (QOL) of 142 primary school teachers and 145 firemen-rescuers. To determine QOL we used a WHOQOL-BREFF questionnaire. Teachers’ QOL was significantly lower in all four domains when compared with firefighters’ QOL; however, it did not differ statistically from the Czech population norms. Significantly lower compared to the norm was only teachers’ satisfaction with their health. Our results showed a significant influence of profession, age and gender on QOL. The influence of subjectively perceived mental stress as a factor reducing the QOL was manifested only in teachers. The explanation for this difference in QOL could be predicting better physical and mental health of firefighters

Smoking Related Systemic and Oral Diseases

This article reviewed smoking related systemic diseases and oral diseases. Smoking is related to lung cancer, cardiovascular diseases and many other systemic diseases. Cigarette smoke affects the oral cavity first, so it is evident that smoking has many negative influences on oral cavity, for example, staining of teeth and dental restorations, wound healing, reduction of the ability to smell and taste, and development of oral diseases such as oral cancer, periodontitis, smoker’s palate, smoker’s melanosis, hairy tongue, leukoplakia, oral candidiasis and implant survival rate. The article also discusses the relationship between smoking and dental caries in detail
