Retrospective analysis of guided access technique in calcified canals using cone beam tomography and digital scanning.
Article in Acta odontologica latinoamericana : AOL, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionThe endodontic treatment of teeth presenting with calcified pulp is associated with significant technical difficulties.
aimTo evaluate the success rate of the guided access technique for root canals using cone beam computed tomography (CBCT) between 2019 and 2021. MATERIAL AND
methodThe study selected cases of anterior and posterior teeth with severe pulp calcification, totaling 100 teeth including 59 incisors, 2 canines, 8 premolars, and 31 molars. CBCT scans were performed for all patients, and a virtual burr path was planned on a computer screen to guide the drill to the beginning of the root canal. The virtual drill path was delineated based on axial and cross-sectional tomographic data, and a template was fabricated using Computer Numerical Control (CNC) technology. Success was determined by reaching the canal lumen without deviation from the original path.
resultsThe success rate of the guided access technique was 99.1%, with calcification diagnosed in 48.7% of cases. Clinical history revealed deep restoration and necrosis in 34.8% of cases, and trauma in 34.8%. In 65.2% of cases, an attempt was made before referral for guided access.
conclusionThe guided access technique demonstrated high success rates, particularly when appropriately indicated. Clinical relevance: Guided access technique provides a reliable option for managing calcified root canals, thereby improving treatment outcomes.
