Associations Between Imaging-Detected Pulp Calcification and Systemic Diseases: A Systematic Review, Thematic Analysis, and Meta-Analysis.
Synthesis in International endodontic journal, 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
backgroundPulp calcification (PC) is a common imaging finding traditionally attributed to local factors or ageing. However, increasing evidence suggests that it may be associated with broader systemic biological disturbances. Clarifying this association may help determine whether dental pulp findings contribute to the interpretation of systemic health.
objectivesTo evaluate whether imaging-detected PC is associated with systemic conditions by synthesising evidence across diverse disorders and identifying recurring biological and methodological patterns.
methodsComprehensive searches were conducted in EMBASE, ProQuest, PubMed, SciELO, Scopus, Web of Science, and the Virtual Health Library up to November 2025. Observational studies assessing associations between imaging-detected PC and systemic conditions were included. Study quality and risk of bias were assessed using the Newcastle-Ottawa Scales and Joanna Briggs Institute tools. A mixed-methods synthesis combined thematic analysis with random-effects meta-analysis. Associations were expressed as odds ratios (ORs) with 95% confidence intervals (CIs), and certainty of evidence was evaluated using GRADE.
resultsThirty-three studies were included, comprising 19 057 patients. The primary meta-analysis (n = 22) showed a statistically significant association between systemic conditions and PC (OR = 2.69; 95% CI: 2.04-3.54), although substantial heterogeneity was observed. Subgroup analyses identified a consistent association for diabetes mellitus, with no statistical heterogeneity (OR = 2.30; I
conclusionCurrent evidence supports a statistically significant association between imaging-detected PC and systemic metabolic and vascular conditions, particularly diabetes mellitus and atherosclerosis-related outcomes. However, the evidence is predominantly observational and does not establish causality, temporality, prediction, or diagnostic utility. PC may represent an imaging finding associated with systemic dysregulation, but its biological significance remains uncertain and its interpretation should remain cautious and context-dependent.
