Background
The immediate microtensile bond strength (µTBS) of self‐etch (SE) adhesives to primary dentine is promising, but evidence about the durability is scarce.
Aim
To assess the long‐term µTBS of SE adhesives to primary dentine and to examine the effect of 7‐s etching on µTBS of a 3‐step etch‐and‐rinse (ER) adhesive.
Design
The enamel of 115 caries‐free human primary teeth was ground flat,...
