Identification of the Inferior Alveolar Canal using Cone-beam Computed Tomography versus Conventional Panoramic Radiography - A Retrospective Study.
Article in Annals of maxillofacial surgery. 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
Introduction: The inferior alveolar canal (IAC) is a critical anatomical structure in the mandible, housing the neurovascular bundle that needs to be protected during dental procedures. Accurate assessment of its location and visibility is vital to prevent surgical complications. Therefore, this study compared the visibility and anatomical positioning of the IAC using conventional panoramic radiography (CPR) and cone-beam computed tomography (CBCT) in different mandibular regions. Materials and Methods: A total of 93 dentulous patients aged over 18 years who had undergone both imaging modalities, CPR and CBCT, were included. Visibility of the IAC was assessed in five mandibular regions using a standardised scoring system, while linear measurements were used to determine its anatomical positioning. Two experienced oral radiologists independently reviewed the images. Data were analysed using SPSS Version 26.0, with Chi-square and linear regression tests applied. Results: CBCT demonstrated significantly better IAC visibility across all mandibular regions compared to CPR ( Discussion: CBCT offers more visibility of posterior teeth than panoramic radiographs, making it more effective for detailed dental examinations. Study findings also showed the IAC differed based on anatomical site, with buccal placement in premolars and lingual placement in molars.
