Objective: Multi-mode universal adhesives offer clinicians the choice of using the etch-and-rinse technique, selective enamel etch technique or self-etch technique to bond to tooth substrates. The present study examined the short-term in vitro performance of five universal adhesives bonded to human coronal dentine.Methods: Two hundred non-carious human third molars were assigned to five groups based on the type of the universal adhesives (Prime&Bond Elect, Scotchbond Universal, All-Bond Universal, Clearfil Universal Bond and Futurabond U). Two bonding modes (etch-and-rinse and self-etch) were employed for each adhesive group. Bonded specimens were stored in deionized water for 24 h or underwent a 10,000-cycle thermocycling ageing process prior to testing (N = 10). Microtensile bond testing (mu TBS), transmission electron microscopy (TEM) of resin-dentine interfaces in non-thermocycled specimens and scanning electron microscopy (SEM) of tracer-infused water-rich zones within hybrid layers of thermocycled specimens were performed.Results: Both adhesive type and testing condition (with/without thermocycling) have significant influences on mu TBS. The use of each adhesive in either the etch-and-rinse or self-etch application mode did not result in significantly different mu TBS to dentine. Hybrid layers created by these adhesives in the etch-andrinse bonding mode and self-etch bonding mode were similar to 5 mu m and
