Abstract :
Cyanoacrylate adhesive material is known to be used as superglue material in fields of dentistry and medicine for years. Moisture insensitivity has rendered the adhesive material useful as orthodontic bonding agent in cases where isolation is difficult. This study was undertaken to measure Shear Bond Strength with Smartbond first bonding and after debonding and repeated bonding twice. 30 test specimens were prepared from extracted maxillary and mandibular premolar teeth, which were subjected to repeat bonding (2 repetitions) using Smartbond and Shear Bond Strength was measured for each of them. Mean Shear Bond Strength of 6.13 MPa ± 2.30 was obtained after first bonding. Mean Shear Bond Strength of 4.17 MPa ± 2.44 and 4.18 MPa ± 1.49 was obtained after first and second rebonding respectively. Smartbond shows optimal Shear Bond Strength at initial bonding but shows Shear Bond Strength to be inadequate after first and second debonding rebonding procedures.
