Clinical applications of polyethylene fibers in dentistry: A metrics-based analysis

Polyethylene fibers have been used in dentistry because of their favorable mechanical and esthetic properties. However, there is a need for a metrics-based review to identify publication trends.

The purpose of this metrics-based analysis was to assess the publication profile and the social interest in the use of polyethylene fibers in dentistry through a bibliometric and altmetric review.

In October 2025, a search was performed in the Web of Science database. The main characteristics of the retrieved publications were extracted and analyzed, with emphasis on the clinical use and applications of this material. Social attention was evaluated in the Dimensions database using altmetric indicators. Collaboration networks were measured using VOSviewer, and the correlation between citation counts and other variables was determined using the Spearman test. Trend analysis was conducted in a spreadsheet.

The selected studies were published between 1988 and 2025 (n=203). The Journal of Prosthetic Dentistry accounted for the largest number of publications (n=18). Most studies were laboratory-based (n=150), and the most investigated clinical applications were the use of polyethylene fibers for dental restorations (n=101), intracanal posts (n=32), and the reinforcement of fixed prostheses (n=26). Most studies focused on adult populations (n=190). Turkey (n=51) was the leading country in publication output, and Asia was the most represented continent (n=113). Limited social attention (n=14) was observed, mainly from readers on Mendeley and users of X and Facebook. VOSviewer indicated collaboration networks among authors. The trend analysis revealed current interest in the use of this material for dental restorations, intracanal posts, and bone reconstruction.

A consistent number of publications was observed over the 37-year period. The studies were predominantly laboratory-based, mainly evaluating the use of polyethylene fibers in dental restorations for adult populations. The clinical applications of this material have undergone several modifications over the years, serving primarily as reinforcement for restorative materials and dental structures. A shortage of clinical studies was identified.
