Statement Of Problem:
Metrics-based reviews that analyze all publications on bulk-fill composite resins to identify publication characteristics and trends are lacking.
Purpose:
The purpose of this study was to analyze the trends and main characteristics of articles related to bulk-fill techniques and composite resins in dentistry.
Material And Methods:
The search was conducted in November 2024 on the Web of Science. Three researchers selected the articles and excluded conference papers. The following data were extracted from the included articles: citations; publication year and journal; study design and topic; authorship and institutions, country, continent, and keywords. Collaboration networks were generated using the VOSviewer software program. The altmetric data were measured by consulting the Dimensions database. The correlation between the data was determined by the Spearman test.
Results:
A total of 801 articles were included. The number of citations ranged from 0 to 270 and the articles had been published between 1988 and 2024. Most studies were laboratory-based (n=692) and evaluated restoration quality and polymerization stress (n=268), primarily high-viscosity composite resins (n=463) in adult patients (n=774). The country with the highest number of articles was Brazil (n=172), while the continent with the most publications was Asia (n=268). The most prominent author was Giannini (n=31) and co-authorship maps showed collaborations between groups of authors. According to Dimensions, significant mentions were identified mainly in news outlets and Mendeley readers, with the altmetric attention score ranging from 1 to 126.
Conclusions:
This study identified an emerging trend in bulk-fill composite resin research in restorative dentistry. The greatest number of studies was published in Brazil, with a strong focus on laboratory studies aiming to investigate restoration quality and polymerization stress in high-viscosity composite resins of interest to Mendeley readers. Further clinical, observational, and systematic review studies are recommended.
