Abstract: Aim: To evaluate the effect of simulated intraoral hydraulic, thermal, and mechanical stresses on the debonding characteristics of orthodontic brackets under different adhesive regimes. Materials and methods: Groups of pre-coated (G1) and non-coated (G2) orthodontic metal brackets were bonded onto the buccal surfaces of 96 premolars using etch-and-rinse (SG1, n = 24) and self-etch (SG2, n = 24) primers. Twelve specimens (C1) from each subgroup were subjected to early debonding resistance tests, while the other… Show more

“…25,26 Previously, it was declared that the minimum required bond strength value for clinically successful bracket bonding is 5.9-7.8 MPa. 11,27 Results of the present work showed insignificant difference in bond strength of the adhesive junction between the bracket and the tooth substrate when dentin was treated with SDF in comparison to the untreated dentin. This was in agreement with previous study stated that application of SDF had no effect on the bond strength between the resin composite materials and sound dentin.…”

“…Easier debonding of orthodontic brackets is more favorable and resulting in lower adhesive remnant indices (ARIs). 27,32 The low ARI score was validated by the adhesive mode of failure which indicates a relatively lower bond strength of the adhesive to the sound dentin in comparison to its bond strength to orthodontic brackets.…”

“…There was a nonsignificant effect of the different ageing models on SBS for both the control and nHAp-SEP groups. The TSEP group survived all artificial ageing protocols recording the highest mean SBS values [ 27 , 30 ]. However, bracket bonding with TSEP yielded significantly higher ARI scores with traumatic debonding after ageing (18 cracked or damaged enamel surfaces).…”

“…[ 1 16 17 ] In the present study, all these methods were employed to achieve varying DoL in the LDI model. Teflon tape was used to simulate periodontal ligaments[ 10 ] because of its resiliency and ease of application over the root surface in contrast to autopolymerizing silicon used in previous studies. [ 18 ] Three coatings of 0.075 mm thick Teflon tape were used to reproduce the average dimensions of PDL.…”
