Abstract:
The purpose of this study was to estimate the quantity of dental implant
literature available on MEDLINE for evidence-based clinical decision-making
and to
identify its location. A search strategy based on Medical Subject Headings
for dental implants was developed to examine MEDLINE using the Ovid Web
Gateway search engine. Sensitive and specific methodologic search filters
identified 4 categories of information: etiology, diagnosis, therapy, and
prognosis. The results were then subdivided by year to identify trends and
sorted to identify the sources of publications. The searches identified
4,655 articles published in English between 1989 and 1999 on human dental
implants on MEDLINE, The mean number of articles (+/- SD) per year ranged
from 15 +/- 11 for specific searches to 107 +/- 50 for sensitive searches.
The number of articles increased by 14% to 43% each year for the sensitive
search. When subdivided by clinical category, the mean numbers of articles
per year for sensitive and specific searches were, respectively: diagnosis
12 +/- 7.5 and 1.5 +/- 1.6, etiology 58 +/- 33 and 1.9 +/- 2.5, therapy 23
+/- 15 and 0.3 +/- 0.5 and prognosis 67 +/- 33 and 12 +/- 8.3. Four dental
journals account for approximately half of these publications. These results
provide 6 key central findings: (1) there appears to be a substantial
literature of clinically relevant information on implants upon which to base
clinical decisions; (2) the implant literature is significantly biased
toward articles addressing prognosis; (3) to stay
current, one would need to read between 1 and 2 articles per week 52 weeks
per year, and this number increases significantly each year; (4)
approximately 50% of the articles were published in 4 journals, whereas the
remainder reside in approximately 97 other journals, making it difficult to
stay current; (5) these trends reaffirm the need for lifelong learning; (6)
these trends also suggest the need for computer-based clinical knowledge
systems.
