Evaluation of midline lingual canal using Doppler ultrasonography and CBCT: a pilot study.
Article in BMC oral health, 2026. 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 main arterial supply to the anterior segment of the mandible consists of a single terminal branch from the anastomosis of the left and right sublingual arteries that enter the lingual foramen and courses through the midline lingual canal (MLC). The aim of the study was to evaluate the correlation between the diameter of the MLC by cone-beam computed tomography (CBCT) and quantitative measurements of the anastomotic arterial branch as obtained by Doppler ultrasonography (USG).
methodsA total of 24 patients (mean age, 48.4 years; range, 20–73 years) with CBCT scans were included in the study. The diameter of MLC was measured on the axial CBCT sections. The volumetric flow rate and the diameter of the artery were assessed using Doppler USG. Statistical analyses were conducted using Student’s t-test and Pearson’s correlation coefficient (r).
resultsThe diameter of the MLC ranged from 0.44 to 1.52 mm. The diameter and the volumetric flow rate of the artery were 1.1–1.9 mm and 1.3–16.9 ml/min, respectively. The MLC diameter was positively correlated with both arterial diameter (r = 0.404, P = 0.05) and arterial blood-flow rate (r = 0.447, P = 0.028).
conclusionsDoppler USG is a safe and effective method for visualizing and measuring the anastomotic arterial branch in the lingual foramen region. The diameter of the MLC on CBCT may indicate the vascularity of the interforaminal region of the mandible.
