Summary
Reinforced zinc oxide eugenol (EBA) cement and amalgam show similar clinical success rates as retrograde root filling materials. Both demonstrated comparable outcomes in healing and bone regeneration over a 3-year follow-up period.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Retrograde root filling is crucial for endodontic surgery success.
- Amalgam has been a traditional material, but concerns exist.
- Reinforced zinc oxide eugenol (EBA) cement offers an alternative.
Purpose of the Study:
- To compare the clinical and radiographic outcomes of EBA cement versus amalgam as retrograde filling materials.
- To evaluate the long-term success rates of these materials over a minimum of 3 years.
Main Methods:
- A comparative clinical study design was employed.
- Patients received either EBA cement or amalgam for retrograde root filling.
- Clinical and radiographic evaluations were conducted post-surgery with a minimum 3-year follow-up.
Main Results:
- Successful healing with complete bone regeneration was observed in 57% of EBA cases and 52% of amalgam cases.
- Uncertain healing occurred in 24% (EBA) and 19% (amalgam) of patients.
- Unsuccessful healing was noted in 20% (EBA) and 29% (amalgam) of patients.
- Statistical analysis revealed no significant difference in healing outcomes between the two materials.
Conclusions:
- Reinforced zinc oxide eugenol cement demonstrates a similar prognosis to amalgam for retrograde root fillings.
- Both materials provide comparable long-term success rates in endodontic surgery.
- EBA cement is a viable alternative to amalgam for retrograde root canal obturation.
