Reasons for dentists' acceptance or rejection of microbiological root canal sampling.

Microbiological root canal sampling (MRS) has been found to be used by only a few Swedish general dentists. The present study addresses the reasons for their acceptance or rejection of the technology. A questionnaire was mailed to 240 general dentists practising within the city of Göteborg. The questionnaire concerned certain practice characteristics and attitudes to MRS. The data showed that MRS is mainly performed by dentists working with adult patients in private practice. The technology is rarely used routinely, but is applied in selected cases. The main reason for non-adoption seems to be a perceived lack of relative advantage over conventional treatment strategies. Furthermore, opinions regarding the complexity and observability of the technology appear to influence acceptance significantly.
