Hydrogel microarchitecture as a regulatory cue for in vitro odontogenic differentiation.
Article in Journal of applied oral science : revista FOB, 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
objectiveThis study introduces an innovative, cost-effective, and easily reproducible strategy for engineering three-dimensional bioprinted GelMA-based scaffolds, designed with ordered macroporous and tubular architectures, and integrated microfluidic channels to advance structural and functional performance. Their geometric features were specifically designed to investigate how microarchitectural cues influence the mineralizing cell differentiation of human dental pulp cells (HDPCs). METHODOLOGY: The scaffolds were fabricated via an indirect bioprinting process using resin molds, resulting in cylindrical structures with distinct grid or honeycomb surface architectures. Biomaterials were characterized for morphology, surface topography, porosity, pore diameter, and degradability. Biological performance was evaluated by culturing HDPCs for 21 days to assess viability, proliferation, and mineralizing differentiation (ANOVA/Tukey; α=0.05).
resultsBoth scaffold designs exhibited interconnected porous networks, with the honeycomb configuration presenting significantly larger pores. HDPCs cultured on the scaffolds showed high viability and proliferation, with the honeycomb architecture promoting elevated ALP activity. However, the grid architecture more effectively influenced odontoblastic differentiation and mineralized matrix deposition.
conclusionOur findings highlight the impact of biomaterial architecture on cellular behavior and reveal the potential of this novel bioprinting approach for bioactive dentin regeneration in dental tissue engineering.
