Summary
This study found that two single-bottle bonding systems, PQ1 and Prime & Bond NT, showed similar effectiveness in preventing microleakage for both compomer and composite restorations in Class V cavities.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
- Clinical Research
Background:
- Microleakage is a significant concern in dental restorations, potentially leading to secondary caries and pulpal issues.
- Compomer materials offer a blend of properties from composites and glass ionomers.
- Single-bottle bonding systems aim to simplify the adhesive application process.
Purpose of the Study:
- To evaluate and compare the microleakage of Class V cavities restored with a compomer material (Dyractflow) using two different single-bottle bonding systems (PQ1 and Prime & Bond NT).
Main Methods:
- Sixty-four Class V preparations on human premolars were restored using either a resin composite or Dyractflow compomer with either the PQ1 or Prime & Bond NT bonding system.
- Specimens underwent 24-hour water storage followed by thermocycling.
- Dye penetration was assessed after sectioning to evaluate microleakage at enamel and cementum margins.
Main Results:
- No statistically significant differences in microleakage were observed between the compomer restorations and the resin composite restorations.
- Both the PQ1 and Prime & Bond NT single-bottle bonding systems exhibited comparable performance in minimizing microleakage.
Conclusions:
- PQ1 and Prime & Bond NT single-bottle bonding systems are equally effective in reducing marginal microleakage when used with compomer or composite restorative materials.
- The choice between these bonding systems does not appear to influence the sealing ability in Class V restorations.
