Sammanfattning
In dentistry the treatments take place in an environment that is
very rich in microorganisms, and there is a risk of transmission of
infection. In order to reduce that risk, we need to actively work to
minimize the sources if infection, and break the routes of transmission.
Working aseptically and thus reducing the probability of contamination,
is a fundamental principle. An aseptic operative field is
created by the use of a rubber dam and antiseptics, and these aseptic
conditions must be maintained during the whole procedure.
90% of Swedish and 30% of Danish dentists use rubber dam
regularly. Though several new techniques for both instrumentation
and obturation have been introduced in recent years, no
reduction of the prevalence of apical periodontitis can be seen.
Other factors, such as the aseptic and antiseptic approach probably
plays a more important role in the outcome of the endodontic
treatment than previously assumed.
