Sealing ability of the single-cone obturation technique with bioceramic sealer iRoot SP in oval root canals: an in vitro study.

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 single-cone obturation technique with iRoot SP demonstrated strong filling capacity in circular root canals; however, its sealing ability in oval root canals remains underexplored. This study aimed to evaluate the sealing performance of the single-cone obturation technique with iRoot SP in oval root canals, in comparison with warm vertical compaction obturation.
methodsA total of 129 single-rooted teeth with oval canals were prepared using rotary instruments and randomly divided into three groups (n = 43 per group): warm vertical compaction obturation with AH Plus (WVC + AH Plus), warm vertical compaction obturation with iRoot SP (WVC + iRoot SP), and single-cone obturation with iRoot SP (SC + iRoot SP). Treatment assignment were blinded to researchers. Sealing ability was evaluated based on void volume percentage using micro-computed tomography, sealer penetration depth and percentage of penetration area in dentinal tubules using confocal laser scanning microscopy, and apical dye leakage depth using transparent teeth. Statistical analyses were conducted using one-way analysis of variance and post hoc Tukey's test with a significance threshold of 5%.
resultsThe SC + iRoot SP group exhibited lower void volumes in the middle and apical thirds of the root canal but higher viod volumes in the cervical third (P < 0.05). In both the WVC + iRoot SP and SC + iRoot SP groups, the maximum and mean penetration depths at 2 mm and 5 mm from the apex were greater, and the percentage of penetration area was higher, compared to the WVC + AH Plus group (P < 0.05). The SC + iRoot SP group also displayed the smallest apical dye penetration depth (P < 0.05).
conclusionSC + iRoot SP demonstrated superior sealing performance in the middle and apical regions of oval root canals making it a suitable option for sealing these specific areas.
