Professional burnout, a long-term consequence of occupational stress, is co
nsidered to be a factor that explains a substantial proportion of incapacit
y for work. Burnout is defined as emotional exhaustion, depersonalization,
and diminished personal accomplishment. Aims: To investigate levels of burn
out among Dutch practising dentists, to compare dentists' scores with norm
scores, and to determine the percentage of dentists "at risk". Methods: The
instrument used was the Dutch version of the Maslach Burnout Inventory (MB
I-NL), a 20-item modified version of the original MBI. A highly representat
ive group of Dutch dentists participated (n=709, 75% response rate). Result
s: Mean levels (and standard deviations) of burnout were: emotional exhaust
ion 13.7 (8.6); depersonalization 5.9 (3.9); personal accomplishment 30.8 (
5.9). Dentists had more favourable means compared with standard scores, alt
hough in the 95th percentile dentists showed more emotional exhaustion than
standards indicate. While no overall sex differences were found, male midd
le-aged dentists tended to show more burnout. Of the working Dutch dentists
, 21% had a certain risk, 13% had high overall levels of burnout, and 2.5%
were highly burned out. Conclusion: It is concluded that Dutch dentists hav
e relatively favourable mean levels of burnout, but those who are exhausted
are extremely exhausted. The male dentist in his forties appears to be mos
t vulnerable to burnout.
