All teeth underwent standardised chemomechanical preparation and were obturated using the THTCT with EndoFill sealer. Immediately after thermomechanical compaction, patients were asked to rate their intraoperative pain intensity using a normalised pain scale. Demographic and clinical variables, including biological sex, tooth type, periapical diagnosis, and sealer extrusion, were also analysed. Intraoperative pain intensity was generally low and was not significantly associated with biological sex (p = 0.251), tooth type (p = 0.211), periapical diagnosis (p = 0.733), or sealer extrusion (p = 0.934). The THTCT was associated with minimal intraoperative pain, supporting its clinical safety, patient comfort, and cost-effectiveness.","PeriodicalId":55581,"journal":{"name":"Australian Endodontic Journal","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148820377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study developed stacked deep learning ensembles for automated detection and radiographic size stratification of periapical lesions. In total, 146 radiographs comprising normal cases and three lesion-size categories were cropped around the root apex and augmented using predefined transformations. Five convolutional neural network backbones were trained, and their probability outputs were combined using multinomial logistic regression (MLR) and gradient boosting (XGBoost) meta-learners. On the internal hold-out test set, both ensembles performed better than the individual backbones. MLR achieved an accuracy of 0.96 and a macro-averaged ROC-AUC of 1.00, while XGBoost achieved an accuracy of 0.95 with a similar AUC. Both ensembles also achieved a sensitivity of 0.94 for lesions < 2 mm. These findings support further investigation of stacking for radiographic decision support, but optimistic estimates from this small, single-centre internal study require prospective multicentre external validation.","PeriodicalId":55581,"journal":{"name":"Australian Endodontic Journal","volume":" ","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148815013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mature teeth had higher fracture strengths than simulated immature teeth. Access cavities reduced fracture strength of simulated immature teeth but not mature teeth.

Patients were grouped according to Periapical Index (PAI) scores.

Severe AP (PAI scores 4–5) was associated with significantly higher SII, NLR, and PIV values (p < 0.05). The number of teeth with PAI score 5 correlated positively with SII, NLR and PIV, whereas PLR showed no significant association. Greater severity of AP was associated with elevated systemic inflammatory indices.
