Abstract:
Objectives: To study publication trends, as well as the number and
proportion of randomised controlled trials covering different areas of
periodontal research (RCT-Ps).

Material and methods: The study was based on MEDLINE searches (MeSH terms)
for the period 1980-2000. The RCT-Ps (n = 675) were examined for relevance
for different areas of periodontal research, journals of publication, and
the countries of origin.


Results: In periodontal research the annual number of publications had
increased from 162 in 1980 to 440 in 2000. Moreover, clinical trials in
periodontal research (CT-Ps) had increased more than 10-fold, and RCT-Ps
more than 15-fold. More than 4 out of 10 RCT-Ps covered the
areas 'periodontal surgery' and,gingivitis and plaque treatment or
prevention'. More than 6 out of 10 RCT-Ps in total and more than 8 out of
10 RCT-Ps about 'periodontal surgery', were published in two different
journals. U.S.A was the most common country of origin of RCT-Ps,
contributing to almost 4 out of 10 RCT-Ps during 1988-2000.


Conclusion: The annual number of RCT-Ps increased substantially during
19802000, and a few clinical research areas predominated. Future research
should give priority to areas where clinical evidence is scarce and where
high-quality RCT-Ps are most needed.
