Long-term performance of flowable bulk-fill restorative systems in Class II restorations: a 7-year randomized clinical trial.

After 7 years, flowable bulk-fill and conventional composite systems showed similar survival rates in Class II restorations, though bulk-fill materials demonstrated more marginal discoloration without affecting restoration longevity.
