Abstract
Objective: To characterize the nature of scientific innovation in dental prosthodontics through the application of the Disruption Index (DI) to literature indexed in PubMed, analyzing its temporal evolution and its relationship with the annual volume of publications and the number of references. Methods: A retrospective bibliometric study based on citation network analysis was conducted. The search was performed in PubMed in December 2025. The DI was calculated using the SciDisruptor-PubMed tool, considering articles published up to 2020, with at least one citation within five years and indexed references. The temporal evolution of the mean DI and its correlations with the number of publications and references were analyzed. Results: Of the 141,829 records identified, 2,980 met the criteria for DI calculation. A marked growth in publications was observed, especially after 2003. A statistically significant negative correlation was found between the number of references and DI (ρ = −0.227; p < 0.001), although with small magnitude. No significant association was observed between annual publication volume and mean DI. Conclusion: Dental prosthodontics demonstrates a moderate and stable disruption profile over time, regardless of the increase in scientific output.
