(1) Background: Microcracks and structural fragility in teeth, often undetected by traditional methods until severe complications like fractures or pulp exposure occur, are evaluated this study using electrical impedance analysis (EIA) as a non-invasive tool for early detection assessment. (2) Methods: A total of 57 patients were recruited, including individuals with bruxism (n = 20), dental restorations 18), no significant history (control group, n 19). Electrical measurements performed on all teeth portable device, data collected from occlusal proximal surfaces. Patients abnormal values underwent additional imaging (standard radiographs) to confirm the presence microcracks. Statistical analyses included ANOVA compare between groups logistic regression assess predictors fragility. (3) Results: Teeth microcracks confirmed standard radiographs exhibited significantly lower (mean 50 kΩ) compared healthy 120 kΩ, p < 0.01). showed highest proportion (45%). Logistic identified predictor reduced (p 0.05). (4) Conclusions: demonstrates promise method detecting assessing teeth. Its application routine check-ups could enable interventions, particularly high-risk restorations.

The study aimed to combine an X-ray micro-computed tomography (μCT) with photoluminescence (PL) and convolutional neural network (CNN) assisted voxel classification volume segmentation for tooth structural integrity assessment at the microcrack site verify this approach extracted human teeth. samples were first examined using μCT segmented CNN identify enamel, dentin, cracks. A new image model was trained based on "Multiclass semantic DeepLabV3+" example implemented "TensorFlow". Secondly, buccal palatal teeth surfaces microcracks sound areas selected obtain fluorescence spectra illuminated wavelengths of 325 nm (cw) 266 (0.5 ns pulsed). proposed – in combination PL reveals possibilities crack area distinct precision versatility can be applied all microstructure surface mapping analysis.
