Impact of Multiple Individualized Guides on the Management of Obliterated Root Canals in a Maxillary First Molar: A Case Report.
Article in European endodontic journal, 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
This report evaluated the impact of using multiple individualized endodontic access guides in the management of obliterated root canals in maxillary molars. A 70-year-old female patient presented with pain in the upper left first molar. Intraoral examination revealed an extensive resin composite restoration, with no signs of tooth mobility or marginal periodontal disease. The clinical diagnosis was symptomatic apical periodontitis. Cone beam computed tomography (CBCT) revealed a hypodense area in the mesiobuccal and palatal (P) roots, associated with signs of apical periodontitis and obliterations in the cervical and middle thirds of the first MB (MB1), second MB (MB2) and P canals. Due to the high risk of perforation, a guided approach to the canals was selected. Multiple guides were designed using digital planning software, combining CBCT images with intraoral scanning. Access cavities were created using a 25 mm long, 1.0 mm diameter surgical bur. After gaining access, the canals were instrumented, medicated with calcium hydroxide for 15 days, and obturated. Twelve months post-treatment, the patient remained asymptomatic, and the clinical results were considered satisfactory. (EEJ-2025-01-06).
