Description
Shikha Ahirwal and six co-authors race four ways to fill deep back-tooth cavities and see which leaks least, in a 2025 lab study. Fillings that end below the gumline's enamel border are notorious for gaps, shrinkage, and failure.
Eighty restorations in extracted premolars were split among two liner strategies, layer-by-layer filling, and a bulk fill. After heat cycling and dye soaking, slices were scored under a microscope. Every group leaked somewhat. The glass ionomer and flowable liner groups leaked most, with scores near 3.7 of 4. Layered and bulk fills scored near 2, significantly better. The authors conclude the liner approaches, at this tricky margin, underperform simpler ones.
