Evaluation of failed endodontically treated molar teeth using micro-computed tomography.
Article in BMC oral health, 2025. 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
backgroundThe present study aimed to assess the internal root canal morphology and the quality of obturation in endodontically treated and failed first molars using micro-computed tomography (micro-CT).
methodsForty-three mesial roots of extracted first molars with failed endodontic treatment were examined using micro-CT to evaluate root canal filling quality and root canal and isthmus configurations. The presence of untreated missed canals and the length of the root canal fillings were assessed. The percentage of voids within the canal filling in both apical and coronal regions was compared using an independent samples t-test. Statistical significance was set at p < 0.05.
resultsAn untreated second mesiobuccal canal was identified in 70.6% (n = 12) of the examined maxillary first molars, while a middle mesial canal was detected in 50.0% (n = 13) of the mandibular first molars. A significantly higher mean percentage of voids within the canal filling was observed in the apical region (15.3%) compared to the coronal region (7.3%) (p < 0.05). Short root canal fillings were observed in 57.7% of mandibular teeth and in 35.3% of maxillary teeth.
conclusionsThe failure of endodontically treated teeth was associated with poor root canal filling quality and the presence of untreated extra canals, as revealed by micro-CT.
