This retrospective multicenter study analyzed 3885 periapical radiographs paired with DEXA\u2010derived\n                    <jats:italic>T<\/jats:italic>\n                    \u2010scores from postmenopausal women. Clinical, handcrafted radiomic, and deep features were extracted, resulting in a fused feature set. Radiomic features (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u2009215) followed Image Biomarker Standardization Initiative (IBSI) guidelines, and deep features (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u2009128) were derived from a novel attention\u2010based autoencoder. Feature harmonization used ComBat adjustment; reliability was ensured by intra\u2010class correlation coefficient (ICC) filtering (ICC \u2265\u20090.80). Dimensionality was reduced via Pearson correlation and LASSO regression. Four classifiers\u2014logistic regression, random forest, multilayer perceptron, and XGBoost\u2014were trained and evaluated across stratified training, internal, and external test sets. A logistic regression model was selected for clinical translation and nomogram development. Decision curve analysis assessed clinical utility. XGBoost achieved the highest classification performance using the fused feature set, with an internal AUC of 94.6% and external AUC of 93.7%. Logistic regression maintained strong performance (external AUC\u2009=\u200991.3%) and facilitated nomogram construction. Deep and radiomic features independently outperformed clinical\u2010only models, confirming their predictive strength. SHAP analysis identified DEXA\n                    <jats:italic>T<\/jats:italic>\n                    \u2010score, age, vitamin D, and selected radiomic\/deep features as key contributors. Calibration curves and Hosmer\u2013Lemeshow test (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.492) confirmed model reliability. Decision curve analysis showed meaningful net clinical benefit across decision thresholds. Dental periapical radiographs can be leveraged for accurate, non\u2010invasive osteoporosis screening in postmenopausal women. The proposed model demonstrates high accuracy, generalizability, and interpretability, offering a scalable solution for integration into dental practice.\n
