Two- and three-dimensional evaluation of endodontic microsurgery outcomes in maxillary anterior teeth with through-and-through lesions: a retrospective cohort study.
Article in BMC oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThis retrospective cohort study evaluated healing outcomes following endodontic microsurgery (EMS) in maxillary anterior teeth with through-and-through periapical lesions (PALs) using periapical radiographs and cone-beam computed tomography (CBCT).
methodsPermanent teeth with through-and-through PALs treated by EMS and followed for more than 24 months were included. Two calibrated endodontic specialists independently assessed two-dimensional (2D) healing according to the Molven criteria and three-dimensional (3D) healing using the PENN 3D criteria. Treatment outcomes were dichotomized as success (complete and incomplete/limited healing) or failure (uncertain and unsatisfactory healing). Preoperative and follow-up lesion volumes were calculated using Mimics software.
resultsSixteen patients (22 teeth, 16 through-and-through lesions) with a follow-up period ranging from 24 to 61 months (mean, 33 months) were included. Complete healing was observed in 62.5% of cases according to the 2D criteria and in 31.3% according to the 3D criteria. The mean lesion volume significantly decreased from 856.97 ± 566.06 mm³ preoperatively to 95.74 ± 180.45 mm³ at follow-up (P < 0.0001).
conclusionsFavorable healing outcomes were observed following EMS in maxillary anterior teeth with through-and-through lesions. CBCT-based assessment applied more stringent healing criteria than periapical radiographs and provided a more comprehensive evaluation of periapical bone regeneration.
