Three-dimensional evaluation of the alveolar antral artery with the aid of cone-beam computed tomography.
Article in SAGE open medicine, 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
Objective: This study aimed to evaluate the prevalence, location, and morphometric characteristics of the alveolar antral artery in an Iranian population using cone-beam computed tomography. Materials and methods: A retrospective analysis was conducted on cone-beam computed tomography images of 322 patients acquired at Shiraz University of Medical Sciences between January 2015 and December 2022. The alveolar antral artery canal presence, mediolateral position (intrasinus, intraosseous, superficial), mediolateral coarse, and morphometry (distances to sinus floor and alveolar crest at the premolar and molar site, and diameter) were assessed. Statistical analysis was performed to identify significant differences based on age, gender, dental status, and side ( Results: The overall prevalence of the alveolar antral artery was 92.2%, most commonly in an intrasinus position (51.3%). The most frequent course was the "in" type (32.4%). Median distances to the sinus floor ranged from 5.09 mm (first premolar) to 7.30 mm (second molar), while distances to the alveolar crest from 16.70 mm (second molar) to 24.65 mm (first premolar). Significant variations in alveolar antral artery canal dimensions and distances were observed based on tooth location, gender, age, and dental status. Conclusion: This study demonstrates a high prevalence and significant anatomical variability of the alveolar antral artery canal in the Iranian population, and underscores the importance of preoperative cone-beam computed tomography imaging to minimize the risk of iatrogenic injury during posterior maxillary surgeries.
