Evaluation of Shear Bond Strength of Various Orthodontic Bracket Bonding Agents

Due to the development of properties adhesive materials currently used in dentistry, bonding ability between brackets and tooth enamel has been greatly improved. In general, situations where cooperation can be obtained, adhesion orthodontic bracket through conventional three-step process show excellent strength. However, if it is difficult expect patient cooperation, as pediatric dentistry area, or moisture isolation not properly performed, binding strength that does reach expected effect. As a result, various products simplify for are being developed. The aim this study was evaluate compare shear 3-step system, self-etching primer system one-step reduces priming process. A total 60 human maxillary, mandibular premolars were prepared. Group I (control group) followed II conditioned with primer. III etched 37% phosphoric acid bonded self-priming adhesive. resultant bond each group measured an remnant index (ARI) recorded. mean I, II, 14.69 MPa, 11.21 MPa 12.21 respectively. Significant differences could only found (p < 0.05). ARI indicated no significant difference among all groups.
