Comparative analysis of estimated age by pulp-to-tooth area ratio using CBCT in three different teeth on a subset of Hyderabad population: A preliminary study.

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
objectivesThe study aims to evaluate the pulp-to-tooth area ratio in permanent maxillary central incisors, lateral incisors, and canines for age estimation using three-dimensional cone beam computed tomography images.
methodsHundred cone-beam computed tomography (CBCT) images of patients aged between 12-70 years were retrospectively studied using NNT Viewer software version 13. Pulpal and teeth area were evaluated with the "area tool" in the acquired images in all three planes, and the pulp-to-tooth area ratio (PTR) was calculated with the measurements obtained. The reproducibility of intra-observer bias using paired t-tests was calculated.
resultsThe coefficient of correlation (r) values of maxillary central incisors with age are -0.54, -0.623, and -0.50 in the axial, sagittal, and coronal planes respectively. The r values of maxillary lateral incisors are -0.05, -0.52, and -0.25 in the axial, sagittal, and coronal planes. The coefficient of correlation values (r) of maxillary canine with the age is -0.53, -0.62, and -0.49 in the axial, sagittal, and coronal planes. A strong correlation between chronological age and PTR in multiple sections of the maxillary incisors and canines (p-value <0.05) was observed.
conclusionThe permanent maxillary central incisor and canine yielded promising results in predicting age. The predicted age derived by mid-sagittal sections was closer to the chronological age than the axial sections, which had the least predictability.
