This study aimed to assess preschool and primary school teachers' knowledge of emergency TDI management and their awareness of the ToothSOS mobile application, a resource providing evidence-based guidance.Methods: A descriptive cross-sectional study was conducted among 427 preschool and primary school teachers in Turkey between May and June 2025. An online questionnaire, based on international guidelines and validated by expert review, collected data on demographics, TDI management knowledge, and ToothSOS awareness. Statistical analyses were performed using non-parametric tests (P < 0.05).Results: The median knowledge score was 3 (range: 0-8). Few teachers correctly identified immediate replantation or storage in milk as appropriate actions for avulsed permanent teeth. Although awareness of the ToothSOS was extremely low, over half of the participants expressed willingness to use it. Significantly higher knowledge scores were observed among teachers with prior trauma education.Conclusion: Teachers demonstrated insufficient knowledge of emergency management of TDIs and limited awareness of digital support tools.

This study investigated the forces and torsional moments exerted on abutment teeth during removal of thermoplastic resin clasps and compared them with those generated by conventional cobalt-chromium (Co-Cr) alloy clasps.Methods: Clasps fabricated from Co-Cr alloy and thermoplastic resin with different undercut depths were examined. Fitness accuracy was evaluated, and tensile tests were performed using a miniature six-axis force/torque sensor. Removal forces and torsional moments acting on the abutment tooth were analyzed along the buccolingual (X-axis), mesiodistal (Y-axis), and vertical (Z-axis) directions. Statistical analyses were conducted to compare materials and undercut conditions.Results: Fitness accuracy ranged from 85 to 130 µm for both clasp types. The thermoplastic resin clasp with a 0.25 mm undercut demonstrated significantly better fitness than the Co-Cr alloy clasp (P < 0.05). Resin clasps with a 0.5 mm proximal undercut generated greater removal forces and torsional moments than metal clasps and resin clasps with smaller undercuts. Increasing the proximal undercut depth in resin clasps resulted in increased retention forces, lateral forces, and torsional moments.Conclusion: Thermoplastic resin clasps with larger proximal undercuts exert greater lateral forces and torsional moments on abutment teeth during removal. Therefore, appropriate selection of undercut depth is essential to reduce potentially harmful stresses while maintaining adequate retention in NMCDs.","PeriodicalId":16646,"journal":{"name":"Journal of oral science","volume":" ","pages":"77-81"},"PeriodicalIF":1.7,"publicationDate":"2026-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147326301","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 fracture modes were analyzed microscopically.

After thermocycling, airborne-particle abrasion maintained the highest bond durability, while hydrofluoric acid etching showed a marked decrease. SEM revealed that airborne-particle abrasion produced a rough surface favorable for micromechanical retention, whereas hydrofluoric acid etching resulted in smoother morphology.Conclusion: Airborne-particle abrasion effectively enhanced and preserved the bond strength between the resin luting agent and feldspathic porcelain-coated zirconia, regardless of the coating sequence.
