Abstract
Biodentine? is currently and regularly used as a direct/indirect capping material and dentine substitute under a resin composite direct restoration. The present study investigated the influence of Biodentine? maturation time on its shear bond strength to a resin-based composite restorative material.
One hundred fifty PTFE tubes were divided into 2 groups (n?=?75), and each group of tubes was filled with a different substrate material (Biodentine? or GC Fuji IX glass ionomer cement). The tubes were subsequently divided into subgroups (n?=?25) that were used to test different substrate maturation times (early, 12?min; medium, 72?h; and delayed, 2?weeks). A resin-based composite restorative material was bonded to the substrates using a 3-step etch and rinse adhesive system (Optibond FL, Kerr), and the bond was tested for shear bond strength.
The Biodentine?/12-min group showed a very low shear bond strength of 2.796?±?2.704?MPa. The values for the Biodentine?/72-h and Biodentine?/2-weeks groups increased as the maturation time interval increased and were 7.986?±?2.100?MPa and 10.553?±?3.281?MPa, respectively. The differences between the Biodentine?/12-min group and the Biodentine?/72-h and Biodentine?/2-weeks groups are statistically highly significant (p?<?.001). The difference between the Biodentine?/72-h group and the Biodentine?/2-weeks group is statistically significant (p?<?.05).
Bonding with Biodentine? that has matured for 72?h results in a statistically significant increase in shear bond strength and yields a more clinically acceptable bond between the two materials.
