Shear Bond Strength Of Metal Brackets To Temporary Crowns With Different Dental Adhesives And Bond Failure, Sirima Charoenpone
Chulalongkorn University Dental Journal
Objectives The purposes of the current study were to compare the mean shear bond strengths of brackets to temporary crowns with and without sandblasting when used by chemical-cured (self-cured) and light-cured composite resin, to self-cured and light-cured glass ionomer, and to evaluate bond failure of all samples. Materials and methods Three hundred temporary crowns were divided into 10 groups with 30 samples in each group to bond metal brackets with sandblasting (SB) or non-sandblasting (NSB). Five kinds of adhesives: one-paste (O), two-paste self-cured (T), light-cured (LC) composite resin, glass ionomer (1) and light-cured glass ionomer (LI) were used. The surface …
