Age estimation from morphometric features of maxillary central incisors using CBCT images.

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
backgroundForensic dentistry is crucial in human identification, with dental age estimation being a key component of this process. The deposition of secondary dentin over an individual's lifetime, along with the resulting changes in tooth anatomy, serves as an important factor in age estimation. The objective of this study was to develop regression equations for estimating age in adults based on linear measurements and ratios obtained from axial, sagittal, and coronal planes of the maxillary central incisors in the Iraqi subpopulation using cone beam computed tomography (CBCT).
methodsIn this retrospective cross-sectional study, Multiplanar measurements of 400 maxillary central incisors from subjects ranging in age from 18 to 84 years were taken for a sample of 200 CBCTs. The data were analyzed using independent Student's t-test, Mann-Whitney test, and Spearman's and Pearson's correlation coefficients to determine the strength of correlations. Multiple regression analysis was performed to predict age, and a p-value of ≤ 0.05 was considered statistically significant.
resultsThe age range of the participants was 18-84 years. The results revealed a statistically significant difference in age between male and female samples (p = 0.018). Consequently, separate age estimation equations were developed for each sex. In males, the equation derived from multiplanar linear measurements demonstrated a standard error of estimate (SEE) of ± 10.84 years, with a coefficient of determination (R²) of 0.49. In contrast, the equation for females, based on multiplanar measurements, yielded a SEE of ± 11.11 years and an R² value of 0.393.
conclusionsBased on the findings of this study, dental morphometric measurement of maxillary central incisors using CBCT was found to be an acceptable method for age estimation especially for identification of unknow human remains. Horizontal measurements improve the accuracy of age estimate equations.
