Solubility was examined according to ISO guidelines in deionised water and phosphate buffer saline (PBS) for 3 months. Surface characteristics and elemental analysis were conducted with scanning electron microscopy and energy-dispersive X-ray spectroscopy, while ion release was determined with ICP-OES. In PBS, solubility values were significantly lower than those recorded in deionised water for both materials (p < 0.05). Upon the AHPB sealer surface, crystalline structures developed that differed in composition, dependent on the immersion solution, whereas no crystal formations were observed on AHP. Calcium ion release of AHPB was significantly higher than AHP throughout the whole study period (p = 0.028). Immersion solution significantly affected solubility and superficial characteristics of materials, highlighting the need to modify experimental protocols to resemble clinical conditions.","PeriodicalId":55581,"journal":{"name":"Australian Endodontic Journal","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144152918","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}

The Student's t-test and Mann-Whitney test were used for statistical analysis (α = 5%). Results showed that both instruments had similar design and composition. Procodile Q had a slightly higher austenitic start temperature and superior cyclic fatigue resistance at 20°C and 35°C (p < 0.001), along with higher surface roughness (p = 0.041).

EF-XR is a newly introduced retreatment file for removal of gutta-percha that has not been evaluated before. Sixteen anatomically matched mesial roots of mandibular molars with mild to moderate curvature were allotted into two groups (n = 8), ProTaper Universal Retreatment files (PTU-RE) and EF-XR. Root canal instrumentation and single cone obturation with BioRoot RCS sealer was performed. Following this, retreatment was done. Pre-and post-Micro-CT analysis was performed to determine the volume of remaining obturating material and root dentin removed and statistically analysed. Within the limitations of the present study, it can be concluded that PTU-RE retreatment files are better than EF-XR files for retrieval of gutta-percha and BioRoot RCS sealer.","PeriodicalId":55581,"journal":{"name":"Australian Endodontic Journal","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144121584","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}

Each main group was further subdivided into three sub-groups (n = 15): nano-hybrid composite resin, short fibre-reinforced composite resin (SFRC) and a CAD/CAM nano-ceramic composite block. After chewing simulation, the specimens were examined using SEM; a quantitative marginal adaptation analysis and fracture resistance test were performed. MOD preparations exhibited the highest marginal deterioration (p < 0.001). Gingival marginal deterioration in nano-hybrid composite restorations was significantly higher than in CAD/CAM restorations (p = 0.023), though the difference between nano-hybrid and SFRC restorations was not significant (p = 0.447).

Accordingly, 24 single-rooted teeth were endodontically prepared using gutta-percha, fibreglass, or metal. Root fractures were caused in 50% of the samples. The teeth were included in a dry jaw and scanned using two tomographic units: OP300 and 3D Veraview. These tomographs respectively achieved an accuracy of 0.88 and 0.83 and a sensitivity of 0.78 and 0.83. The OP300 Maxio device had a high specificity of 0.98 compared to the 3D Veraview's 0.83. Thus, the two devices tested were both adequate for the identification of root fractures. However, the 3D Veraview demonstrated greater accuracy in the detection of root fractures in roots containing metal posts, while the OP300 showed greater accuracy with the use of fibreglass posts. The presence of gutta-percha compromised the identification of fractures with both devices.","PeriodicalId":55581,"journal":{"name":"Australian Endodontic Journal","volume":" ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143996478","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}
