Novel approaches involving curcumin in endodontic and periodontal diseases: a scoping review.
Article in BMC oral health, 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
backgroundEndodontic and periodontal diseases are common oral diseases. Traditional treatments, such as root canal disinfection and scaling, are limited by challenges such as microbial residue, tissue damage, and antibiotic resistance. Curcumin, a natural polyphenol derived from turmeric, exhibits antibacterial, anti-inflammatory, and tissue regeneration properties. This scoping review aimed to integrate the research status and application prospects of curcumin in endodontic and periodontal diseases, explore the transformation of basic research into clinical application, and provide guidance for the dual challenges of infection control and tissue repair encountered by clinicians.
methodsThe scoping review was conducted according to the PRISMA extension for scoping reviews. PubMed, EBSCOhost, and SpringerLink were searched for relevant studies. English studies published after 2019 were retrieved. The included studies were manually screened, covering animal experiments, clinical trials, and in vitro experiments. Using a standardized form, two reviewers independently extracted data and resolved disagreements through discussion. The application of curcumin in root canal disinfection, filling materials, and periodontal treatment was comprehensively evaluated.
resultsThis review included 31 studies (8 clinical studies). Curcumin, as a photosensitizer for photodynamic therapy in root canal disinfection, showed superior deep bactericidal efficacy and biocompatibility; however, broader clinical application requires further clinical research. In deciduous teeth root canal filling, curcumin formulations have varied therapeutic effects; thus, comparative studies are required to facilitate translation from experimental findings to clinical practice. As periodontal treatment, curcumin demonstrated excellent bactericidal, anti-inflammatory, and tissue repair capabilities; however, more trials are needed to provide clinical evidence for validating its performance and supporting its clinical application.
conclusionPreliminary studies show curcumin's potential in antibacterial activity, biocompatibility, and osteogenesis in endodontic and periodontal diseases. However, its practical effects remain inconclusive owing to data heterogeneity and methodological limitations. More clinical studies are warranted to reach definitive conclusions.
