Dental restoration failure rates are higher than reported in electronic health records (EHRs). Manual chart reviews reveal discrepancies, emphasizing the need for accurate dental documentation.
Area of Science:
- Dental Materials Science
- Evidence-Based Dentistry
- Health Informatics
Background:
- Amalgam and composite restorations are common for minor dental issues.
- Electronic Health Record (EHR) data suggest low failure rates: 2.31% for amalgam and 1.14% for composite.
- Discrepancies between EHR data and actual clinical outcomes necessitate further investigation.
Purpose of the Study:
- To determine the true failure rates of amalgam and composite dental restorations.
- To compare manual chart review findings with existing EHR data.
- To identify documentation gaps in dental EHR systems.
Main Methods:
- Manual review of 216 amalgam restorations (2020-2022) and 350 composite restorations (2021) from University of Michigan School of Dentistry patient data.
- Defined restoration failure as replacement with the same or alternative material within one year.
- Calculated failure rates based on retreatment and alternate treatment data.
Main Results:
- Amalgam failures: 1.85% retreated, 7.87% alternate treatment.
- Composite failures: 9.71% retreated, 2.86% alternate treatment.
- Overall failure rates identified through manual review exceeded those reported in EHRs.
Conclusions:
- Manual chart review indicates higher dental restoration failure rates than initially reported in EHRs.
- Accurate and precise documentation practices are crucial for aligning EHR data with clinical reality.
- Improving EHR data integrity is essential for reliable dental research and practice management.
