Summary
This study compared Lysanda (zinc oxide-eugenol paste) with different additives and mineral trioxide aggregate (MTA) for root-end filling. All tested materials demonstrated acceptable apical sealing, with Lysanda paste with iodoform showing minimal leakage.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Effective apical sealing is crucial for the success of root-end fillings in endodontic therapy.
- Lysanda, a zinc oxide-eugenol based paste, is used as a root-end filling material, often with radiopacifiers.
Purpose of the Study:
- To compare the apical sealing ability of Lysanda paste, modified with iodoform, zinc oxide, or calcium hydroxide, against mineral trioxide aggregate (MTA).
Main Methods:
- Root-end cavities were prepared and filled with five different materials: Lysanda with iodoform, Lysanda with iodoform and calcium hydroxide, Lysanda with iodoform and zinc oxide, Lysanda with zinc oxide, and MTA.
- Marginal leakage was assessed using 2% methylene blue dye immersion.
Main Results:
- Marginal leakage was observed in all experimental groups.
- Lysanda paste with iodoform exhibited the least amount of leakage.
- No statistically significant differences in leakage were found between the groups.
Conclusions:
- All tested materials, including Lysanda formulations and MTA, are viable options for root-end filling.
- Lysanda paste with iodoform demonstrated comparable apical sealing performance to MTA.
