Abstract:
Background: The oral leukoplakia and erythroplakia is one of the most common
epithelial precursor lesions of the oral squamous cell carcinoma. Transformation
rates are approximately 0.9-17% in 10 years for leukoplakia and in 14-50% for
the erythroplakia. Despite the clinical relevance of these lesions, currently
exists no detailed bibliometric analysis.
Methods: The present study combines classical bibliometric tools with novel
scientometric and visualizing techniques in order to analyse and categorize
research in the field of leukoplakia and erythroplakia.
Results: All studies related to leukoplakia and erythroplakia and listed in the ISI
database since 1900 were identified by the use of defined search terms. The
bibliometric analysis of the collected data shows a continuous increase in
quantitative marker such as the number of publications and cooperation and
qualitative markers, such as citations and H-index. The combination with
density equalizing mapping revealed a distinct global structure of research and
citing activity. Radar chart techniques were used to illustrate bi- and
multilateral cooperations and institution research collaborations.
Discussion: The present study demonstrates the first scientometric approach
that visualizes research activities in the area of leukoplakia and erythroplakia.
It provides data that can be used for geografical context and research
networks.
