Dentin Bonding Performance of Universal Adhesives in Primary Teeth In Vitro.

(1) Background: The aim of this in vitro study was to evaluate the micro-tensile bond strength (µ-TBS) of universal adhesives to primary tooth dentin after different storage periods. (2) Methods: Dentin of 100 extracted primary molars was exposed. Dentin surfaces were bonded with six universal adhesives (AdheseUniversal [AU], All-Bond Universal [ABU], G-Premio Bond [GPB], iBondUniversal [IBU], Prime&Bond active™ [PBa], and Prime&BondNT as control [PBN]) and restored with a resin composite build-up (Filtek™ Z250).
