Professional Training and Clinical/Radiographic Factors Associated With Endodontic Decision-Making: A Before-and-After Study.
Article in European journal of dental education : official journal of the Association for Dental Education in Europe, 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
introductionEndodontic decision-making is influenced by clinicians' professional training and by the clinical and radiographic characteristics of each case. This study aimed to assess the association of these factors with treatment decisions and to determine whether the addition of clinical information modifies treatment choices compared with radiographic analysis alone. MATERIALS AND
methodsThirty clinical cases involving endodontically treated teeth were evaluated through electronic questionnaires by 56 participants with different educational backgrounds (undergraduate students, general practitioners, postgraduate endodontic students, and endodontists). In the first questionnaire (Q1), only periapical radiographs were provided. One month later, a second questionnaire (Q2) included additional clinical information. Participants selected the most appropriate treatment option for each case. Changes in decisions between Q1 and Q2 (categorised as wait-and-see vs. reintervention) were analysed using the McNemar test. Associations between examiner- and tooth-related factors and treatment decisions were assessed using multilevel binary logistic regression (α = 0.05).
resultsWait-and-see and nonsurgical retreatment were the preferred options at both time points. Endodontists recommended reintervention more frequently in Q2 than in Q1. In Q1, older examiners were more likely to recommend reintervention. Decisions were also influenced by tooth-related factors, with altered periapical conditions and inadequate root canal fillings being associated with a higher likelihood of reintervention, whereas posterior teeth, iatrogenic errors, and inadequate coronal restorations/prosthetic crowns were associated with a lower likelihood. In Q2, specialty training in endodontics and prior reintervention decisions in Q1 were strong predictors of reintervention, along with selected clinical and radiographic factors.
conclusionsConservative approaches were generally preferred. However, professional training and specific clinical and radiographic characteristics significantly influenced reintervention decisions.
