Summary
Bonded amalgams show comparable two-year retention to resin sealants for pit and fissure treatment without mechanical preparation. This suggests bonded amalgam is a viable option for preventive restorations.
Area of Science:
- Dental Materials Science
- Preventive Dentistry
Background:
- Pit and fissure sealants are crucial for preventing dental caries.
- Traditional sealants often require mechanical preparation, which can be invasive.
Purpose of the Study:
- To evaluate the two-year retention of bonded amalgams used as pit and fissure sealants without mechanical preparation.
- To compare bonded amalgam retention with that of resin-based sealants.
Main Methods:
- Bonded amalgams were applied as pit and fissure sealants without prior mechanical preparation.
- Resin-based pit and fissure sealants served as the control group.
- Clinical examinations were conducted at six months, one year, and two years post-application.
Main Results:
- No statistically significant difference in sealant retention was observed between bonded amalgams and resin-based sealants at all follow-up points.
- Both sealant types demonstrated comparable durability over the two-year study period.
Conclusions:
- Bonded amalgams can be effectively used as pit and fissure sealants without mechanical preparation.
- This technique offers a promising alternative for preventive amalgam restorations, especially in conservative preparations.
