Sammanfattning
The work at a dental clinic implies getting in contact with different
chemical substances, which may cause temporary or permanent
injury to the staff, primarily allergic reactions, but also
local irritation, carcinogenic or toxic effects. Dentists and dental
assistants belong to the professional groups most frequently experiencing
work-related eczema. The chemical substances may
originate from dental materials, such as mercury from amalgam
and monomers from resin based materials. The substances may
be released during preparation, polishing and removal of restorations.
In addition, different biocides/chemical disinfectants are
used for both clinical an infection control purposes. Finally, medical
gloves contain allergenic latex protein and rubber chemicals
and may cause irritant eczema.
Basically, damages can be prevented by substitution of hazardous
substances, the choice of approved products, compliance
with set threshold limits and thorough planning of the work
considering health aspects including the preparation of local
guidelines. As development of injury follows either direct contact
or inhalation of chemical substances, the damage can be prevented
by measures such as the use of “no touch technique”,
high-volume evacuation reducing spatter and aerosol formation
and proper use of personal protective equipment in the form of
protective gloves and eyewear and surgical masks.
