Patients' perceptions play an important role in assessing the quality
of dental treatment. This study investigated 56 possible quality aspec
ts on their importance as judged by regular attenders. A nationwide sa
mple of 5000 Dutch people was contracted, 1328 persons meeting our sel
ection criteria filled out the questionnaire and responded. The result
s show that hygiene of instruments and the availability of the dentist
in case of emergency were considered the most important. It was concl
uded that in general these patients judged technical and functional as
pects of dental care to be of more importance than communicative and i
nformative aspects. Differences in perceptions were found according to
sex and, to a lesser extent, to education, means of insurance and pla
ce of residence. But, on the whole, response patterns were homogeneous
