Hypothesis
The mechanical performance of partially replaced coronal fillings is equivalent to that of completely replaced restorations in root canal-treated teeth.
Conclusion
Partially replaced restorations presented higher fracture strength and led to fewer irreparable fractures compared to totally replaced restorations.
Supporting Evidence
- The average failure load of the TR group was 1115.13 N and 1330.23 N in the PR group.
- The TR group exhibited eight irreparable fractures, while the PR group had four.
- Statistical analysis showed significant differences in mechanical resistance between the two groups.
Takeaway
This study found that fixing a tooth without removing the whole filling is often stronger and better than replacing everything.
Methodology
Thirty maxillary second premolars were tested for fracture strength after being restored with either totally or partially replaced restorations.
Potential Biases
Potential bias due to the in vitro nature of the study and the use of a single type of resin composite.
Limitations
The study was conducted in vitro and used the same type of resin composite for repairs, which may not reflect real clinical situations.
Participant Demographics
Freshly extracted human intact mature maxillary second premolars.
