A field of view-based assessment of soft tissue calcifications in cone beam computed tomography of the maxillofacial region.

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
Soft tissue calcifications are frequently encountered in radiographic examinations. Since some of these calcifications are associated with systemic diseases and potentially serious conditions, accurate radiographic diagnosis can assist in managing the underlying pathology. This study aimed to determine the frequency and size of soft tissue calcifications in cone beam computed tomography (CBCT) scans covering either the maxilla or mandible. 420 CBCT scans with a field of view (FOV) of either the maxilla or mandible were evaluated in patients aged 6 to 82 years. Depending on the FOV type, the scans were evaluated for the presence and size of various calcifications. Furthermore, associations between calcification frequency and size with age and sex were statistically analyzed. A significance level of 0.05 was applied. Tonsilloliths were the most frequently observed calcifications in both FOV types, followed by calcified stylohyoid ligaments (CSLs), with most calcifications being of medium size. Overall, soft tissue calcifications were more frequently detected in the mandibular FOV (p = 0.01). Independent of calcification type and FOV, a significant correlation was observed between increased patient age and both higher frequency (p < 0.001) and larger size (p = 0.003) of calcifications. Tonsilloliths and CSLs are the most common calcifications observed in CBCT scans of both the maxilla and mandible. In mandibular FOVs, especially in patients ≥ 50 years, particular attention should be paid to calcifications of the carotid arteries, stylohyoid ligaments, and tonsilloliths. An FOV‑specific checklist may improve reporting consistency and referrals for appropriate medical/dental follow‑up.
