Who Gets to Be Read? Factors Affecting Full‐Text Access Rates in Periodontology and Implantology Research

Objective This study aimed to identify the variables associated with full‐text access rates in studies published in Periodontology and Implantology. Methods A bibliometric analysis was performed by reviewing the 30 top‐ranking journals in Dentistry, Oral Surgery and Medicine. Only journals with a number of text accesses were included. Independent variables analysed included publication date, first author's country, open access status, h‐index, study design, and thematic focus. Multivariable Poisson regression with robust variance was used. Results A total of 3880 studies were included, revealing an access rate (number of views per month) of 83.68 ± 143.62. The journal's impact factor (rate ratio [RR]: 1.09; 95% confidence interval [95% CI]: 1.07–1.11) and being in the open access mode (RR: 1.78; 95% CI: 1.64–1.94) influenced the access rate. Moreover, studies from America (RR: 1.16; 95% CI: 1.02–1.31), Oceania (RR: 1.56; 95% CI: 1.23–1.98), and Europe (RR: 1.50; 95% CI: 1.33–1.69) had significantly higher access rates than those from Asia. Regarding study designs, randomised clinical trials (RCT) (RR: 1.70; 95% CI: 1.47–1.97) and literature reviews (non‐systematic reviews [RR: 1.65; 95% CI: 1.27–2.14] and systematic reviews [RR: 1.78; 95% CI: 1.52–2.08]) exhibited greater access than in vitro/animal studies. Conclusion Access to articles in Periodontology is significantly linked to study design (RCTs and reviews), open access availability, and higher journal impact factors.
