Accuracy of static-guided endodontics for access cavity preparation with pulp canal obliteration: a randomized controlled clinical trial.
Trial report in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
backgroundLocating calcified canals in teeth with pulp canal obliteration remains particularly challenging. The absence of data from randomized controlled trials conducted in vivo has been a critical gap. The objective of this study was to comprehensively assess the accuracy of static-guided endodontics in addressing the challenges of pulp canal obliteration through a randomized controlled clinical trial, as well as pain during treatment and clinical outcomes.
methodsEighty patients with pulp canal obliteration were selected from July 2020 to March 2022 and randomly divided into two groups. In the freehand group, patients underwent contemporary freehand access cavity preparation. Patients in the static-guided group underwent innovative access cavity preparation using three-dimensional-printed endodontic guides for precise root canal localization. The quantitative accuracy was subsequently evaluated through meticulous assessment of indirect impression scans obtained from the access cavities. Moreover, pain during treatment and clinical outcome were investigated.
resultsAll participants were randomly assigned to treatment groups. The static-guided group showed high accuracy, with average deviations of 0.14 ± 0.08 mm at the coronal entry point, 0.35 ± 0.16 mm at the apical point, and an angular deviation of 1.75 ± 0.30 °. These deviations were significantly lower than those in the freehand group (P < 0.0001). No significant difference were found between the groups regarding pain during treatment and clinical outcomes after one year (P > 0.05).
conclusionThis study demonstrates, within its limitations, the static endodontics guides represent an accurate method in locating root canals for pulp canal obliteration through a randomized controlled clinical trial.
