Dentists belong to a professional group potentially exposed to harmful biological factors which most often are infectious microorganisms, less frequently - allergenic or toxic microorganisms. The fundamental routes of spreading harmful microorganisms in a dental surgery are: blood-borne, saliva-droplet, direct contact with a patient and with infected equipment, and water-droplet infections. In this paper, the current status of knowledge on microbiological hazards in a dentist's work is presented. Groups of microorganisms, such as prions, viruses, bacteria, fungi and protozoa, to which a dentist is, or may be exposed, are discussed. Epidemiological assessment of microbiological hazards in a dentist's work was performed and the basic principles of prevention formulated. Special attention was given to microflora in dental unit waterlines, and the biofilm persisting in them, as a source of occupational hazards specific for a dentist's workplace.

Many-year studies on aerosols as an infection vector, despite their wide range, ignored dental aerosol. All procedures performed with the use of dental unit handpieces cause the formation of aerosol and splatter which are commonly contaminated with bacteria, viruses, fungi, often also with blood. Aerosols are liquid and solid particles, 50 μm or less in diameter, suspended in air. Splatter is usually described as a mixture of air, water and/or solid substances; water droplets in splatter are from 50 μm to several millimetres in diameter and are visible to the naked eye. The most intensive aerosol and splatter emission occurs during the work of an ultrasonic scaler tip and a bur on a high-speed handpiece. Air-water aerosol produced during dental treatment procedures emerges from a patient’s mouth and mixes with the surrounding air, thus infl uencing its composition. Because air contained in this space is the air breathed by both dentist and patient, its composition is extremely important as a potential threat to the dentist’s health. According to the author, insuffi cient awareness of health risk, working habits, and economic factors are the reasons why dentists do not apply the available and recommended methods of protection against the infl uence of bioaerosol and splatter. Behaviour protecting a dentist and an assistant from the threat resulting from the infl uence of dental aerosol cannot be limited to solated actions. The author, on the basis of the literature and own research, characterizes bioaerosol and splatter in a dental surgery and reviews a full range of protective measures against these risk factors.

Aerosols generated in dental operations are a source of exposure to microorganisms proliferated within dental unit waterlines (DUWL) biofilm. It has been suggested that presence of Legionella species in these aerosols may contribute to potential health hazards for dental staff and patients. The article attempts to provide a brief overview of the current knowledge about Legionella, its prevalence in DUWL, immunological reactions of the dentists and concepts for prophylaxis of Legionella in dentists' work place.

In this study, pollen grains were sampled by using a Lanzoni trap (Lanzoni VPPS 2000) in atmosphere of Bursa in 1999 and 2000. During two years, a total of 13,991 pollen grains/m3 which belonged to 59 taxa and unidentified pollen grains were recorded. A total of 7,768 pollen grains were identified in 1999 and a total of 6,223 in 2000. From these taxa, 36 belong to arboreal and 23 taxa to non-arboreal plants. Total pollen grains consist of 78.61% arboreal, 20.37% non-arboreal plants and 1.03% unidentified pollen grains. In the region investigated, Pinus sp., Olea sp., Platanus sp., Gramineae, Cupressaceae/Taxaceae, Quercus sp., Acer sp., Morus sp. Xanthium sp., Castanea sp., Chenopodiaceae/Amaranthaceae, Corylus sp., Artemisia sp., Urtica sp. and Fraxinus sp. were responsible for the greatest amounts of pollen. During the study period the pollen concentration reached its highest level in April.

A qualitative and quantitative evaluation of pollen concentration in the atmosphere of Izmir metropolitan area is presented. Investigations were undertaken from November 1998 to October 1999 using gravimetric method. The aeroplynological studies revealed that at lower level (1.60 m) pollen from 29 woody and 30 herbaceous taxa were determined, whereas at higher level (20 m) pollen from 26 woody and 24 herbaceous taxa were recorded. At lower level, dominating woody species were Pinus, Quercus, Oleaceae, Cupressaceae/Taxaceae; herbaceous species were Gramineae, Chenopodiaceae/ Amaranthaceae, Cruciferae and Plantago. At higher level, Pinus, Cupressaceae/Taxaceae, Gramineae, Chenopodiaceae/Amaranthaceae, Cruciferae and Plantago pollens were dominant. Morus, Oleaceae, Quercus, Chenopodiaceae/Amaranthaceae, Gramineae and Plantago showed highest concentration and their allergic degree was very high. Annual pollen calendar of the area is shown.

This study attempted to develop farmers' health and farmers occupational health services (FOHS) by examining the effects and feasibility of empowered farmers' teams on walk-through surveys of Finnish dairy farms. FOHS personnel of the health centre in three municipalities selected three farmer teams for the intervention group. Each team consisted of three or four couples. The selected comparison group resembled the intervention group. The number of the farms was 31 in the intervention group and 33 in the comparison group. Before and after the intervention each subject responded to questionnaires. The initial walk-through survey was carried out in 1998-1999, and the follow-up took place in 2000-2001. During the follow-up the FOHS personnel identified the changes made after the initial surveys on the farms. The farmers and FOHS personnel also underwent a thematic interview. Altogether 217 changes were made, half of them to improve ergonomics, and 87 of the 217 were extensive. The empowered farmer groups produced more changes in the work environment. The use of empowered farmer groups is feasible in walk-through surveys, and the approach can be easily learned. Empowered groups are also a challenge for FOHS personnel, and they enrich the work of these workers. The farmers want more varied measures for work-site health promotion, and, particularly, they feel that an occupational health physician should be present on walk-through surveys.
