Comparison of ultrasonography and cone-beam computed tomography for quantitative assessment of mental foramen and alveolar crest.
Article in BMC oral health, 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
backgroundThe mental foramen (MF) represents an anatomical aperture situated on the anterior aspect of the mandible bilaterally and constitutes a significant reference point for surgical procedures. The purpose of this study was to evaluate the usefulness of ultrasonography (USG) in determining the location and dimension of the MF and its distance to the alveolar crest in comparison with cone-beam computed tomography (CBCT).
methodsThe study was conducted on 27 patients (13 males, 14 females) over 18 years of age (19-73 years) who applied to the Department of Dentomaxillofacial Radiology for a CBCT scan before planning of implant procedures. The vertical diameter of the MF and its distance from the alveolar crest were measured on CBCT cross-sectional slices and compared with the measurements obtained by USG.
resultsA total of 54 MFs were evaluated. The measurements of the vertical diameter of MF and its distance to the alveolar crest were consistent between CBCT and USG (P = 0.262 and P = 0.551, respectively). In either technique, the vertical diameter of MF was significantly higher in males whereas the distance to alveolar crest was significantly higher in females (P < 0.001). No significant age differences were observed in USG and CBCT measurements regarding MF diameter and distance to the alveolar crest (P > 0.05)
conclusionsUSG is as accurate as CBCT in measuring MF and associated alveolar crest and has the potential for the localization of vital anatomical structures with the advantage of no concern about ionizing radiation.
