摘要

Abstract Background . Many adhesive systems have been investigated as alternatives to conventional bonding methods. Selfetching primers and resin modified glass ionomer cement have been introduced to overcome the disadvantages of acid etching Objectives . To assess the effect of using either a self etching primer (SEP) or a resin modified glass ionomer (RMGI) on shear bond strength and failure type in comparison with conventional methods (CM). Material and Methods . Eighty metal brackets were bonded to buccal surfaces of human upper premolars by the same clinician according to 1of 4 protocols. Group 1, Transbond XT was used with self-etching primer (SEP) Transbond Plus (3M Untiek, Monrovia, Calif). Group 2, resin modified glass ionomer (RMGI) Fuji Ortho LC (GC Crop, Japan). Group 3, light cure resin (LC) Transbond XT (3M Unitek, Monrovia, Calif) were used with 37% phosphoric acid. Group 4, Chemically cure resin (CC) Unite (3M Unitek, Monrovia, Calif) were used with 37% phosphoric acid. The premolars were stored in distilled water for 24 hours at 4oC. Brackets were loaded to failure in Instron machine. Descriptive statistics were calculated. ANOVA, Bonferroni, Kruskal-Wallis tests and MannWhitney U were used. Results . The present study indicated that the SEP provided no significantly higher shear bond (10.01 ± 5.46 MPa) than LC adhesive (8.59 ± 4.07 MPa) while RMGI showed the lowest (5.08 MPa). A comparison of the adhesive remnant index (ARI) scores indicated that there was significantly difference between the groups with less residual adhesive remaining on the teeth with SEP and RMGI. Conclusion . SEP produced bond strength clinically accepted with less amount of residual adhesive left on the enamel while RMGI produced unacceptable bond strength. SEP can use successfully in bond orthodontic brackets.
