Hypothesis
The study aims to compare the efficacy of three placement techniques in marginal sealing of Class V composite restorations extending onto the root.
Conclusion
None of the placement techniques produced gap-free margins, but the split-increment technique showed reduced microleakage compared to the others.
Supporting Evidence
- The oblique and occlusogingival techniques showed higher degrees of microleakage.
- The split-increment technique preserved the bonded gingival margin integrity.
- Dye penetration was larger at gingival margins than at occlusal margins.
Takeaway
The study tested three ways to fill cavities in teeth, and while none completely stopped leaks, one method worked better than the others.
Methodology
Thirty extracted human molars were restored using three different composite placement techniques and assessed for microleakage.
Limitations
The study was conducted in vitro, which may not fully replicate clinical conditions.
Participant Demographics
Thirty sound, freshly extracted human molars were used.
