Detection of proximal dental caries in primary teeth with a near-infrared-irradiation-assisted intraoral scanner: an in vitro study.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled it.
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 early detection of dental caries is crucial for successful dental care. New intraoral scanners using near-infrared irradiation (NIRI) technology track preventive lesions without ionizing radiation. This study aimed to evaluate the performance of intraoral scanners (IOSs) in detecting proximal caries in primary posterior teeth, compared to conventional methods such as loupes-assisted clinical exams and bitewing (BW) radiography.
methodsFifteen examined tooth surfaces were used to produce a total of 60 scores by a restorative dentistry consultant (RDC). The tooth surfaces were categorized into caries-free (n = 5 × 4 exam methods) and carious (n = 10 × 4 exam methods) subgroups. Artificial caries lesions were created on specified surfaces and mounted on typodont in sets for evaluation using a simplified modified ICDAS visual and BW radiographic examination, DIAGNOcam device, and iTero Element 5D NIRI-assisted IOS. Reference surface scores were recorded. Investigators (RDCs and recent dental graduates (RDGs)) were trained and calibrated. Inter-examiner agreement, agreement with reference, specificity, and sensitivity were checked.
resultsThe results showed that the sensitivity and specificity differed between the diagnostic tests. The best agreement of all investigated diagnostic methods with the reference was found using the DIAGNOcam device (ĸ = 0.87) and BW radiography (ĸ = 1.00). High agreement was found for visual examination (by the RDC and RDGs (ĸ ≈ 0.85)) and iTero 5D examination (ĸ = 0.87).
conclusionsThe iTero Element 5D IOS had lower sensitivity and specificity compared to other methods. The potential use of IOSs with NIRI as a substitute for conventional diagnostic methods in primary teeth shows promise but requires further investigation.
