Impact of self-confidence and personality on dental students' radiographic interpretation skills.
Article in BMC medical education, 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
backgroundAccurate radiographic interpretation is essential for diagnostic decision-making in dentistry. Alongside technical training, individual characteristics such as self-confidence and personality traits may influence students’ diagnostic performance.
methodsThis cross-sectional study included 83 fifth-year dental students who interpreted 11 panoramic radiographs of histopathologically confirmed lesions. Students provided two differential diagnoses and rated their confidence for each case. Personality traits were assessed using the Turkish Big Five 50 Test. ANOVA was used to compare diagnostic accuracy between personality groups, and Hayes’ PROCESS Model 2 examined whether gender or personality moderated the association between confidence and diagnostic accuracy.
resultsSelf-confidence significantly predicted diagnostic accuracy (B = 0.50, 95% CI: 0.22–0.78, p < 0.001). No significant differences were observed among personality profiles (p = 0.549), and neither gender nor personality traits showed significant moderation effects. Diagnostic accuracy was highest in cases where students reported high confidence.
conclusionSelf-confidence showed a strong positive association with diagnostic accuracy, whereas personality traits and gender had no significant influence. Educational strategies that enhance confidence calibration and provide structured feedback may help improve radiographic interpretation skills and promote safer clinical decision-making.
