Recruiting Dental Practices for Research: Insights from a Practice-Based Trial in Germany.
Article in JDR clinical and translational research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundWhile the relevance of implementation research in dentistry is increasingly emphasized, practice-based trials are still relatively uncommon in dental research. Despite being critical for successful practice-based research, little is known about the recruitment of dental professionals to participate in practice-based trials. Against this background, the purpose of this study was to extract key learnings about the opportunities and challenges for recruiting dental practices from a large-scale practice-based trial in Germany.
methodsLeveraging quantitative and qualitative methods, participation rates of dental practices and experiences of researchers involved in a large-scale trial in German dental practices were examined. Quantitative analyses focused on the rate of practices that initially expressed interest to participate in the trial, the rate of practices that subsequently gave informed consent to participate in the trial, and variations in participation by different modes of invitation for the study. Qualitative data from dental practices and a focus group with the research coordinators were analyzed by means of thematic analysis, focused on drivers and barriers for practices to participate in the trial.
resultsOf 6,840 invited practices, 287 (4.2%) practices indicated their interest and 159 (2.3%) participated. The mode of invitation was significantly associated with participation ( DISCUSSION: While practice-based research is key to driving positive change in oral health systems, the findings of this study suggest considerable barriers for recruiting dental practices to participate in research. Understanding the mechanisms through which participation rates can be increased is crucial for the successful operationalization of practice-based research in dentistry. Implementation-oriented research in dentistry would benefit substantially from enhancements of practice-based research networks.
trial registrationThe underlying project was registered prospectively on July 3, 2023, at the German Clinical Trials Register (www.drks.de) under ID DRKS00030587.Knowledge Transfer Statement:The results of this study can be used by clinicians and clinical researchers when planning practice recruitment for practice-based trials. This could allow for more precise sample size planning and ultimately contribute to improved patient health through the increased validity of studies.
