Pain severity was classified using the visual analogue scale (VAS). Demographic variables (age, sex) and MRI features—including lesion side, disc position, disc morphology, disc signal, disc perforation, bilaminar zone tear, joint space, joint effusion, condylar movement, bony changes and morphology/signal of the lateral pterygoid muscle—were collected. Eleven ML models based on demographic and MRI features were developed: logistic regression (LR), support vector machine (SVM), random forest (RF), extreme gradient boosting (XGBoost), light gradient boosting machine (LightGBM), adaptive boosting (AdaBoost), gradient boosting classifier (GBC), bagging classifier (BC), extremely randomised trees (ETC), decision tree classifier (DTC) and multilayer perceptron (MLP). Model performance was evaluated using multiple metrics, including the area under the receiver operating characteristic curve (AUC), accuracy, sensitivity, specificity and F1 score. Precision–recall (PR) curves and calibration curves were plotted to assess discrimination and model calibration. Decision curve analysis (DCA) was conducted to evaluate the clinical net benefit across a range of threshold probabilities. Model interpretability was enhanced using Shapley Additive Explanations (SHAP), which quantified the contribution of each feature to individual predictions.

Participants were classified into AB and control groups based on self-report and Ecological Momentary Assessment (EMA). Surface electromyography (sEMG) of the masseter muscle was recorded during five conditions: rest, maximal voluntary clenching, self-report questionnaires, mathematical tasks of different complexity, and an electronic memory game (Genius). Episodes were analysed at thresholds of 10%, 20%, and 30% of maximal voluntary contraction (Ap10, Ap20, Ap30), extracting frequency, duration, and amplitude. Dispositional mindfulness was assessed using the Five Facet Mindfulness Questionnaire (FFMQ). Statistical analyses included Friedman tests, Mann–Whitney &lt;i&gt;U&lt;/i&gt; tests, Generalised Estimating Equations (GEE), and Spearman correlations.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Controls showed increased episode frequency at lower thresholds (Ap10) as task complexity rose, whereas AB individuals maintained elevated frequencies across all tasks. Significant between-group differences were observed at higher thresholds (Ap20, Ap30). Duration and amplitude showed no significant differences, except for a trend of greater amplitude in controls during the Genius task. Within the AB group, higher dispositional mindfulness was associated with fewer and shorter contraction episodes, a pattern consistent with previous research indicating a potential protective association.

This condition, including attrition, abrasion and erosion, can result in sensitivity, aesthetic decline and functional impairment. Although dental caries prevention has improved, tooth wear remains a complex, multifactorial problem requiring early detection and effective management.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Objectives&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;This paper is a literature survey that provides an overview and compares three diagnostic systems for tooth wear assessment—the Smith and Knight Index (TWI), Basic Erosive Wear Examination (BEWE) and Tooth Wear Evaluation System (TWES 2.0)—as recommended by the European Consensus Statement (2017). BEWE is primarily designed to assess erosive tooth wear, whereas TWI and TWES 2.0 provide a more comprehensive evaluation that also encompasses attrition and abrasion. This paper evaluates the suitability of all three indices for both population-level screening and individual patient assessment, focusing on efficiency, detail and ease of use. All three indices can be applied for screening purposes and for detailed evaluation of patients, although their primary applications may differ: BEWE is primarily used for screening populations, whereas TWI and TWES 2.0 are more often employed for assessing individual patients requiring treatment. It should be noted, however, that the TWI is not a screening tool but a diagnostic index intended for detailed clinical evaluation. The article also examines limitations, especially regarding the assessment of wear on restorative materials, and explores emerging technologies.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;A literature review was conducted to assess the clinical relevance, diagnostic performance and practical application of the TWI, BEWE and TWES 2.0, based on a literature search performed using PubMed, Embase, ScienceDirect and Web of Science databases. Key outcome parameters compared for each index included scoring system, focus area, simplicity, level of detail, sensitivity to early wear, inclusion of restorations, ease of standardisation, application, advantages and limitations.
