Summary
C & B Metabond cement demonstrated superior retention for preformed posts compared to Panavia, All-Bond 2, and Ketac-Cem. This finding is crucial for dental post cementation success.
Area of Science:
- Dental Materials Science
- Prosthodontics
- Biomaterials Engineering
Background:
- Post-endodontic restorations require reliable cementation for long-term success.
- The choice of cement significantly impacts the retention of prefabricated posts in endodontically treated teeth.
Purpose of the Study:
- To compare the retention strength of four different dental cements used for cementing prefabricated posts.
- To identify the most retentive cement among C & B Metabond, Panavia, All-Bond 2, and Ketac-Cem.
Main Methods:
- Sixty maxillary canine teeth underwent endodontic treatment and preparation for prefabricated posts.
- Posts were cemented using one of the four tested cements (C & B Metabond, Panavia, All-Bond 2, Ketac-Cem) in four groups of 15.
- A universal testing machine (Instron) measured the forces required to dislodge the cemented posts.
Main Results:
- C & B Metabond exhibited the highest post retention (p < 0.05).
- No significant difference in retention was found between Ketac-Cem and Panavia cements.
- All-Bond 2 showed the lowest retention among the evaluated cements.
Conclusions:
- C & B Metabond is the most retentive cement for prefabricated posts based on this study.
- Clinicians should consider cement retentiveness when selecting materials for post-endodontic restorations.
- Further research may explore the long-term clinical performance of these cements in vivo.
