From lesion to resolution: A cone-beam computed tomography-based retrospective comparison of bioactive materials in nonsurgical root canal therapy.

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
Aim: To evaluate periapical healing following nonsurgical root canal treatment of large periapical lesions using three bioactive materials, assessed using cone-beam computed tomography (CBCT) at 6 months and 1 year. Materials and Methods: A total of 40 teeth were taken for this retrospective study with single or multirooted teeth and periapical pathology of 4-8 mm in diameter, present with preoperative and follow-up CBCT scans available. All the cases considered underwent endodontic treatment using one of three bioactive materials (mineral trioxide aggregate, Biodentine, and bioceramics). Assessment of healing was done based on radiographic CBCT scans and CBCT-periapical index (PAI) criteria. The teeth were divided into healing, healed, or diseased based on the changes in the CBCT-PAI score after 6 months and 1 year. All the data were recorded in a tabular form and sent for statistical analysis using Chi-square test, t-test, and Friedman's test. Results: While there was a statistically significant difference in individual teeth after 6 months ( Conclusion: Among all the teeth assessed, single-rooted maxillary teeth showed the highest amount of healing. All three bioactive materials showed a favorable outcome for the treatment regardless of the material used. In addition, healing outcomes were not significantly influenced by patient age or gender.
