Comparative evaluation of single camera photogrammetry and LIDAR-based facial scanning.
Article in Dental press journal of orthodontics, 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
introductionOrthodontic diagnosis and treatment planning relies on precise diagnostic records, including facial imaging. While two-dimensional (2D) photography is widely used, it cannot fully represent three-dimensional (3D) facial structures. Recent advances in 3D imaging, including LiDAR-based scanning and single-camera photogrammetry (SCP), offer improved accuracy.
objectivesThis study evaluates these cost-effective 3D scanning methods in facial soft tissue assessment, by comparing measurements from SCP and LiDAR-based mobile apps, with manual method measurements as gold standard.
methodsThirty-six patients (21 females, 15 males) aged 15-25 years requiring orthodontic treatment participated. Scanning was conducted using SCP and LiDAR technology, while manual measurements used digital calipers. Statistical analysis evaluated accuracy, precision, and reliability.
resultsBoth SCP and LiDAR-based scanning techniques show clinically acceptable accuracy in facial soft tissue analysis. LiDAR-based scanning demonstrates better depth perception than SCP, though both methods are viable alternatives to conventional imaging.
conclusionThe study highlights smartphone-based 3D facial scanning as viable alternatives to traditional imaging in Orthodontics. While SCP and LiDAR scanning show comparable accuracy, further research is needed. The findings support implementing affordable 3D scanning technologies in orthodontic diagnostic protocols.
