Keyword Analysis

Keyword analysis uncovers frequently occurring terms and themes within a dataset, helping to identify research trends, gaps, and emerging technologies. This step involves mapping keywords to visualize research clusters.

Example:

Using VOSviewer, analyze keywords like "biocompatibility," "dental implants," and "minimally invasive dentistry." A PubMed-derived dataset might highlight the prominence of specific terms over time.

In an analysis of 2020–2023 publications, keywords associated with "Minimally Invasive Dentistry" include:

  • High Frequency Keywords: "tooth preservation," "caries management," "laser dentistry."
  • Emerging Terms: "bioactive materials," "nanotechnology."

For example, the article:

  • Authors: Salazar M., Jones T. Title: Nanotechnology in Minimally Invasive Restorative Dentistry. Journal: Dental Materials, 2022. DOI: 10.1016/j.dentalmat.2022.08.009

Keywords can be mapped to demonstrate research growth in bioactive materials and their impact on dental restoration.
