“…Our fi ndings that groups II and IV showed no signifi cant differences in the distribution of ARI scores, but signifi cant differences in mean shear bond strength supported results found by some investigators 10,[18][19][20] who reported that the amount of residual adhesive on the enamel might not be related to shear bond strength.…”

The purposes of this study were to evaluate the effects of different degrees of water contamination on the shear bond strength of orthodontic brackets bonded to dental enamel with a moisture-insensitive primer (MIP) adhesive system and to compare the modes of bracket/adhesive failure. A total of 68 human premolars were divided into four groups by primers and enamel surface conditions (desiccated, blot dry, and overwet). In group I, the hydrophobic Transbond XT primer adhesive system was used under desiccated conditions for bonding the brackets; in group II, the hydrophilic Transbond MIP adhesive system was used under desiccated conditions; in group III, the hydrophilic Transbond MIP adhesive system was used under blot dry conditions; and in group IV, the hydrophilic Transbond MIP adhesive system was used under overwet conditions. Shear bond strength was measured with a universal testing machine, and the mode of bracket/adhesive failure was determined according to the adhesive remnant index. The mean shear bond strengths were not significantly different among groups I, II, and III, and were higher than the clinically required range of 6 to 8 MPa. The mean shear bond strength achieved in group IV was significantly lower than that achieved in groups I, II, and III, and also lower than the clinically required values. Bond failure occurred at the enamel-adhesive interface more frequently in group IV than in groups I and III. To achieve clinically sufficient bond strengths with the hydrophilic MIP adhesive system, excess water should be blotted from the water-contaminated enamel surface.

“…In the present study we found significant differences in the shear bond strengths of brackets bonded with phosphoric acid-etching between deciduous and permanent teeth after enamel treatment with both systems, which agrees with previous result [26] . The significantly lower shear bond strength in the deciduous teeth might be explained by the outer prismless enamel layer and the adhesive thickness between the bracket base and the enamel surface.…”

“…Bond strengths between 6 and 8 MPa are clinically sufficient for successfully bonding orthodontic brackets to enamel [24][25][26][27][28] . Our findings showed that the shear bond strengths of all the 4 groups were higher than the clinically required range of 6 to 8 MPa.…”

Egyptian Orthodontic Journal 78 Volume 39 -June 2011with the sulphated polyacrylic acid were left clean with no or minimal adhesive remnants, after brackets debonding. The deciduous enamel treated with the sulphated polyacrylic acid revealed formation of less abundant crystals than that appeared on permanent teeth enamel as shown by the SEM. Thus it is concluded that, 40% sulphated polyacrylic acid can be used for bonding metallic brackets to deciduous and permanent teeth.

“…11,12 The pH of Transbond Plus self-etching primer worked out at 0.4 and increased little within 10 minutes (pH 0.4 to 0.5); that of Beauty Ortho Bond self-etching primer was 1.5 and did not increase at all. Although self-etching primers generally produce less demineralization of enamel than is produced by phosphoric acid etchants, 14 the pH of Transbond Plus self-etching primer might be too acidic to yield a satisfactory bond strength for attaching brackets to enamel.…”

“…10 Some researchers reported no significant differences in mean bond strength between self-etching and acid-etching adhesive systems. 11,12 Others showed that the selfetching adhesive system had a significantly lower bond strength than the acid-etching adhesive system. 13,14 Bracket failure due to uncontrollable impact forces or the inevitable removal of brackets to replace them in an ideal position is not a rare experience for clinicians during orthodontic treatment.…”

Objective: To ascertain the effects of repeated bonding on the shear bond strength of orthodontic brackets bonded with a fluoride-releasing and -recharging adhesive system with a self-etching primer in comparison with two other types of adhesive system. Materials and Methods: A total of 48 premolars were collected and divided equally into three groups of 16. Each group was assigned one of three adhesive systems: Transbond XT, Transbond Plus, or a fluoride-releasing and -recharging adhesive system, Beauty Ortho Bond. Shear bond strength was measured 24 hours after bracket bonding, with the bonding/debonding procedures repeated twice after the first debonding. A universal testing machine was used to determine shear bond strengths, and bracket/adhesive failure modes were evaluated with the adhesive remnant index after each debonding. Results: At every debonding sequence, all of these three adhesive systems had a shear bond strength of 6 MPa, which is a minimum requirement for clinical use. Transbond XT and Transbond Plus had significantly higher mean shear bond strengths than did Beauty Ortho Bond at each debonding. No significant differences in mean bond strength were observed between the three debondings in each adhesive system. Bond failure at the enamel/adhesive interface occurred more frequently in Beauty Ortho Bond than in Transbond XT or Transbond Plus. Conclusions:The fluoride-releasing and -recharging adhesive system with the self-etching primer (Beauty Ortho Bond) had clinically sufficient shear bond strength in repeated bracket bonding; this finding can help orthodontists to decrease the risk of damage to enamel at debonding.
