Advancements and challenges in stem/progenitor cell transplantation for dentin-pulp regeneration: a systematic review of animal studies (part I).
Review in American journal of stem cells, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
Dentin-pulp regeneration through stem/progenitor cell transplantation represents a promising frontier in regenerative endodontics. This systematic review meticulously evaluates animal studies to investigate the efficacy of stem cell therapy in repairing/regenerating the dentine-pulp complex in mature/immature animal teeth. Employing a comprehensive electronic search of PubMed and Scopus databases up to October 2023, relevant English studies were identified/assessed. Evaluation parameters encompassed radiographic and histological assessments of dentin-pulp complex formation. Outcome measures included pulp-like and dentin-like tissues regeneration, apical healing, dentin thickening, apical closure, and dentinal bridge formation. The risk-of-bias assessment adhered to the Systematic Review Centre for Laboratory Animal Experimentation (SYRCLE) guidelines. Out of 3250 identified articles, 23 animal experiments were included, categorized into regenerative procedures in mature teeth (n=11), regenerative procedures in immature teeth (n=4), and vital pulp therapy (n=8). Despite the promising potential, the bias in the included studies was high. Notably, Various scaffolds, and growth factors were employed, highlighting the heterogeneity across the studies. Dental pulp stem cells (DPSCs) and bone marrow stem cells, especially specific subfractions, demonstrated notable regenerative potential: hypoxic conditions and extracellular vesicles from preconditioned DPSCs enhanced regeneration, with considerations of cell fate. Donor age impacted regeneration, and challenges persisted in pulpotomy and direct pulp capping. Scaffold and growth factor choices influenced outcomes, underscoring the need for standardized strategies. Despite the promise, clinical viability faces hurdles, necessitating further investigation into adverse effects, optimized scaffolds, and regulatory considerations. This systematic review illuminates the potential of stem cell transplantation for dentin-pulp complex regeneration. The overall evidence quality, influenced by study heterogeneity and biases, underscores the need for cautious interpretation of findings. Future studies should refine methodologies and establish reliable histological parameters for meaningful advancements in dentin-pulp regeneration.
