Abstract

Objective: The goal of this pilot study was to present a new index system (GFsa©) based on two variables, the total citations and “scientific age”, to evaluate the best-ranked researchers in dentistry. Methods: All researchers included were cited in the AD Scientific Index (2024, dentistry field) and had their Google Scholar page accessible for a manual consultation. Two authors retrieved this information. A dataset was prepared (name, H-index, i10 index, and publications). The formula applied was GFsa = (total number of citations)/(“scientific age”) 2 . The Pearson correlation statistically evaluated the data obtained; the confidence interval was 95%. Results: A total of 1020 were included. The mean “scientific age” was 34.18 ± 13.34. The GFsa© index was calculated, presenting a minimum value of 0.2186 and a maximum of 154.8. The data were organized and sorted following the ranking obtained. The Pearson correlation showed that the H-index had a weakly positive association with the researcher’s “scientific age”; thus, the H-index increased according to the increase in “scientific age”. By contrast, a moderately negative correlation between GFsa and “scientific age” was demonstrated. Moreover, a positive correlation was observed between both indexes. Conclusions: The variable reported (“Scientific age”) provided a better evaluation among the researchers in dentistry.
