Overview

In vitro study evaluates microleakage in Class II restorations, showing variable effects of composite types and fiber reinforcement.

Key Points

  • This study aims to assess the impact of composite type and polyethylene fiber reinforcement on microleakage in Class II resin composite restorations.
  • In vitro study on 40 extracted human premolars randomly assigned to five groups (n = 8).
  • Restorations evaluated included conventional composite, bulk-fill composite, and short fiber-reinforced composite.
  • Microleakage assessed post-thermocycling using 2% methylene blue dye and analyzed with Kruskal–Wallis test.
  • Bulk-fill composite group exhibited the highest microleakage scores (P < 0.001).
  • Short fiber-reinforced composite group showed the lowest microleakage scores with superior marginal sealing performance.
  • Polyethylene fiber reinforcement was associated with reduced microleakage in conventional and bulk-fill composites.
