Radiographic Assessment of Normal Periapical Bone Density: A Descriptive Analysis Based on Digital Imaging.

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: Accurate evaluation of alveolar bone density is essential for dental diagnosis and treatment planning. Panoramic radiographs offer relative estimates of bone density. Due to limited data in Iranian populations, this study assessed the radiographic density of normal periapical bone using panoramic imaging. Materials and Methods: This descriptive cross-sectional study analyzed digital panoramic radiographs at three anatomical regions-anterior, premolar, and molar-in both jaws. A standardized 1.5 mm × 1.5 mm region of interest (ROI) was positioned within 2 mm of the apical third of each tooth. Bone density was quantified as gray values (arbitrary units [AU]) using Digora software. Demographic data were collected, and statistical comparisons between groups were performed using independent Results: In 458 panoramic radiographs (212 males, 246 females; ages 20-50), bone density was significantly higher in males, older individuals (35-50), and the mandible compared to the maxilla. Density decreased from anterior to molar regions. The anterior mandible showed the highest values, with notable differences from the anterior maxilla, while premolar and molar regions showed no significant interjaw differences. Conclusion: Panoramic radiographs revealed consistent patterns in periapical bone density. Density was higher in males, older adults, and the mandible compared to the maxilla. The anterior mandible showed the highest values overall. In the maxilla, bone density increased from anterior to posterior regions. These findings support baseline assessment and suggest further validation with 3D imaging.
