1 · What the graph read from it

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.

2 · The registry

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

Objectives: This study aimed to assess the quality of canal obturation in 3D-printed C-shaped canals using Micro-CT and dye penetration with different filling techniques. Methodology: Sixty 3D-printed teeth with C-shaped canals were obturated using: AH Plus with continuous wave (AHCW), iRoot SP with single cone (SPSC) and iRoot SP with continuous wave (SPCW). Micro-CT was used for 3D reconstruction in two regions: 0~8 mm (overall canal) and 0~3 mm (apical segment). The volume of voids (V1) and total canal volume (V) were used to calculate porosity as (V1/V) × 100%. Sealing quality was assessed by dye penetration. Results: Results showed that AHCW exhibited significantly lower porosity within 8 mm (5.17%) compared to SPSC (9.02%) and SPCW (8.55%), (P < 05). No significant porosity differences were observed within 3 mm or in dye penetration. Conclusion: AHCW achieved better obturation in the middle and upper segments, with no significant differences among techniques in the apical segment.
