Summary
GC Fuji Triage glass-ionomer and Delton FS+ with bonding agent showed 100% retention after two years of aging and abrasion. Triage offers advantages in fluoride release and technique simplicity for pediatric dental sealants.
Area of Science:
- Dental Materials Science
- Pediatric Dentistry
- Preventive Dentistry
Background:
- Dental sealants are crucial for preventing pit and fissure caries.
- Evaluating sealant retention under challenging clinical conditions, such as saliva contamination, is essential.
- Glass-ionomer and resin-based sealants have different properties and clinical performance characteristics.
Purpose of the Study:
- To compare the retention of GC Fuji Triage (glass-ionomer) versus Delton FS+ (resin-based sealant) on saliva-contaminated enamel.
- To assess sealant durability after simulated aging and mechanical abrasion.
- To determine the clinical applicability of these sealants in a contaminated environment.
Main Methods:
- Seventy-two extracted human molars were divided into three groups: Triage, Delton FS+ with bonding agent, and Delton FS+ alone.
- Sealants were applied to saliva-contaminated occlusal surfaces.
- Samples underwent thermocycling and toothbrush abrasion simulating 2 years of clinical use.
- Retention was evaluated clinically and via scanning electron microscopy (SEM).
Main Results:
- Delton FS+ alone showed a 37.5% failure rate after 2 years, confirmed by SEM.
- GC Fuji Triage and Delton FS+ with bonding agent demonstrated 100% retention throughout the study period.
- Both successful groups exhibited comparable wear rates.
Conclusions:
- GC Fuji Triage and Delton FS+ with bonding agent offer superior retention compared to Delton FS+ alone, even on contaminated surfaces.
- GC Fuji Triage presents advantages in fluoride release and ease of application, particularly for newly erupted molars.
- Both Triage and Delton FS+ with bonding agent are effective sealant options for caries prevention.
