Evaluation of the effectiveness of panoramic radiography in maxillary 3rd molars on an artificial intelligence model developed with findings obtained with cone beam computed tomography.

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
backgroundPanoramic radiography (PR) is accessible for determining the contact between third maxillary molar teeth (tMMT) and the maxillary sinus floor (MSF). However, this method does not provide clear and detailed anatomical information, so more advanced imaging techniques may be required.
aimThis study aims to evaluate the positional relationship between tMMT and the MSF using PR images analyzed by deep learning (DL) models trained with cone-beam computed tomography (CBCT) data. The study also compares the classification performance of different DL architectures. MATERIALS AND
methodsA total of 1,054 PR images of tMMT were analyzed. The relationship between the tMMT and MSF was categorized based on CBCT findings into three classes: no relation, contact, and sinus-related. Five DL models (VGG16, VGG19, ResNet50, ResNet101, and GoogleNet) were trained and tested across four classification problems. Performance metrics, including accuracy and confusion matrices, were evaluated. Final results were aggregated using a majority voting-based fusion strategy.
resultsFor binary classification (relation vs. no relation), accuracies were 89.34% for right tMMTs and 91.24% for left tMMTs. For the three-class problems (relation, contact, no relation), the accuracies were 68.72% and 69.2%, respectively. The highest classification success was achieved in the "no relation" class. Depending on the problem, the most successful models were VGG16, VGG19, and ResNet101.
conclusionDL models can effectively identify the anatomical relationship between tMMTs and MSF on PR images, especially in cases that are challenging to interpret visually. This approach has the potential to reduce reliance on CBCT imaging, providing objective diagnostic support and saving time for clinicians.
