Determining the Failure Rate of Direct Restorations-Chart Review versus Electronic Health Record Reports.

Amalgam and composite restorations are used to treat minor dental issues. University of Michigan, School of Dentistry Electronic Health Record (EHR) reports show a 2.31% failure rate for amalgam and 1.14% for composite. Our study aims to determine the true failure rates through manual EHR chart reviews. Patient data from the University of Michigan School of Dentistry were utilized-216 amalgam restorations from 2020 to 2022 and 350 composite restorations in 2021 were searched. We defined failure and retreatment as replacing a restoration with the same material and failure and alternate treatment as replacing restoration with an alternative treatment within one year. The failure rate refers to a combination of replacement with the same and alternative treatment material within one year. For Amalgam: 1.85% failed and were retreated; 7.87% failed and were received an alternate treatment. Composite: 9.71% failed and retreated; 2.86% failed and received alternate treatment. In total anterior composite: 10.5% retreated, 2.6% failed; posterior composite: 9.1% retreated, 3.0% failed. Our study revealed higher restoration failure rates than the reports extracted in the EHR. This highlights the need to foster a culture of precise documentation to align EHR reports with hand-search findings.

Evaluation of Sealing Ability of MTA Flow, Biodentine and Pro-Root MTA to Seal the Furcal Perforation with and without Internal Matrix- An In vitro Study.

Introduction: Endodontic mistakes, also known as procedural accidents, are those bad events that occur during treatment, some of which are attributable to a lack of attention to detail and others of which are completely unforeseeable. The second most frequent reason for root canal failure is perforation. Aims and Objective: The current in vitro study's objective was to assess the furcal perforation's potential to be sealed with and without internal matrix by MTA flow, Biodentine, and pro-root MTA. Materials and Methods: 60 samples were allocated into six groups at random (10 each). In intact permanent mandibular first and second teeth, furcal perforation sites were made and sealed with various materials. Following perforation sealing, the specimens' capacity for sealing was evaluated using the dye penetration method. Result: The current study's findings indicated that Group 2 has the least amount of microleakage and Group 5 has the most. Conclusion: Biodentine has excellent sealing capabilities and can be utilised to heal furcation perforations with or without internal matrix.
