Abstract
Background The immediate microtensile bond strength (mu TBS) of self-etch (SE) adhesives to primary dentine is promising, but evidence about the durability is scarce. Aim To assess the long-term mu TBS of SE adhesives to primary dentine and to examine the effect of 7-s etching on mu TBS of a 3-step etch-and-rinse (ER) adhesive. Design The enamel of 115 caries-free human primary teeth was ground flat, and bonding was performed according to group assignment: G-aenial (TM) Bond/GC [GB], Clearfil (TM) SE Bond/Kuraray [CS], OptiBond (TM) XTR/Kerr [OX], Scotchbond (TM) Universal/3M (TM) [SU], Prime&Bond(R) NT (TM)/Dentsply [PB], and OptiBond (TM) FL/Kerr [OF]. After storage (24 h, 6 mos., 12 mos.), 1,762 beams were cut for mu TBS testing. Fracture analysis was performed using light/fluorescence microscopy. Resin-dentine interfaces were exemplarily analyzed using SEM. Results After 24 h, OX and SU showed significantly higher estimated mean mu TBS than GB, which exhibited the lowest mu TBS at all stages (p < .05). mu TBS within each adhesive group showed slight variations over time (p > .05). OF_SE produced acceptable mu TBS. Etching increased the mean immediate mu TBS for OF (p > .05) and the percentage of cohesive fractures. Conclusions SE adhesives achieved durable mu TBS to primary dentine. 7-s etching may improve the immediate mu TBS of a 3-step ER adhesive.
