Assessment of the Pulp/Tooth Ratio and Third Molar Root Completion Status for Forensic Age Estimation in an Iraqi Population.
Article in Cureus, 2025. 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
objectivesThis retrospective cross-sectional study evaluates the effectiveness of using the pulp/tooth area ratio of mandibular second molars for identifying minors (<18 years) in an Iraqi population and compares its diagnostic performance to the third molar root completion status.
methodsA total of 216 panoramic radiographs were analyzed. Pulp/tooth area ratios were measured using ImageJ (National Institutes of Health, Bethesda, MD), and third molar root completion was recorded as a binary variable. Three logistic regression models were constructed and evaluated using sensitivity, specificity, and area under the ROC curve (AUC).
resultsIncomplete third molar root development showed high sensitivity (0.90), while the second molar pulp/tooth ratio demonstrated superior specificity (0.99). The combined model (ratio + third molar) yielded the highest overall performance (AUC = 0.96), outperforming individual predictors (third molar only: AUC = 0.90; ratio only: AUC = 0.84).
conclusionWhile the pulp/tooth ratio alone is less sensitive, it provides excellent specificity and enhances overall model performance when combined with third molar status. These findings support the combined use of both variables for accurate age estimation in forensic settings lacking reliable documentation.
