The Use of Micro-Computed Tomography in Dentistry: A Bibliometric Analysis

Micro-computed tomography (micro-CT) is widely used in dental research because it provides high-resolution three-dimensional imaging of mineralized tissues. The aim of this study was to evaluate scientific production, research trends, and thematic development related to the use of micro-CT in dentistry through bibliometric analysis. Publications published between 1995 and 2025 were retrieved from the Web of Science Core Collection database. A total of 3,358 articles and reviews were included in the analysis. Bibliometric analyses were performed using Bibliometrix and Biblioshiny. Annual scientific production, keyword co-occurrence, trend topics, thematic map, and thematic evolution analyses were examined. The results showed that the number of publications increased steadily over time and reached its highest level in 2025. Keyword co-occurrence analysis revealed that “micro-CT” and “micro-computed tomography” were the most frequently used terms and were closely associated with endodontics, periodontitis, dental implants, osseointegration, enamel, and caries. Trend analyses showed that research interests shifted from general imaging and in vitro studies to more specific topics such as endodontics, periodontitis, inflammation, bone regeneration, and dentin. In conclusion, the use of micro-CT in dentistry has increased considerably over the years and has become an important research tool in several dental disciplines.
