Estimation of root canal conicity of deciduous canines evaluated by nano-CT.
Article in European archives of paediatric dentistry : official journal of the European Academy of Paediatric Dentistry, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeTo estimate the taper of root canals of deciduous maxillary and mandibular canines by nano computed tomography (nano-CT).
methodsThis in vitro study involved CT scan analysis of nine maxillary and five mandibular primary canines. The images of each tooth were reconstructed using OnDemand3D software. Thereon, diameter and taper analyses were performed on the free FreeCAD 0.18 software for the three-dimensional (3D) computer-aided design model. Statistical analysis was conducted using Stata v14.0 software, adopting a significance level of 5%.
results3D image reconstruction was performed, considering the diameters obtained along the entire length of the tooth root, and the conical model was built with a height of 10 mm. The diameters of the maxillary canine at points D0 (0 mm), D5 (5 mm), D7 (7 mm), and D10 (10 mm) were 1.62, 1.07, 0.78, and 0.49 mm, respectively, with a significant difference between the four points (p = 0.0001). Regarding maxillary canine root taper values in the cervical, middle, and apical regions, the values were 12%, 14%, and 10%, respectively. For mandibular canines, the mean diameter values obtained at points D0, D5, D7, and D10 were 1.51, 0.83, 0.64, and 0.45 mm, respectively, with significant differences among the four points (p = 0.005). The inferior canine root tapers in the cervical, middle, and apical regions were 14%, 10%, and 6%, respectively.
conclusionThe detailed knowledge of the root morphology of maxillary and mandibular deciduous canines, as it has been shown in vitro using nano-CT, is critical to achieve accurate and efficient endodontic treatments.
