The purpose of this in vitro study was to evaluate the efficacy of self-etching primer which was developed to simplify the bonding procedures by measuring the shear bond strength and observing the interfacial morphology.
90 flat dentinal surfaces were prepared by grinding the buccal and lingual areas of caries-free human deciduous molars. After bonding of composite resin to sample surfaces according to the manufacturer¢¥ s direction and thermocycling, shear bond strengths were measured using Universal testing machine(Instron). Another groups of specimens were treated by hydrochloric acid to secure the resin only and those tags were evaluated under SEM for their length and forms and the morphology of the bonding sites were also observed
The result as follows.
1. Group )Q showed higher shear bond strength than group I and If but no statistically significant difference was founded between group I and 11 (p>.05).
2. Adhesive failure was predominant in group 11 whereas dentin detachment was the main failure pattern in group I and II[ .
3. Relating long resin tags of 100 - 200um were observed in samples of all groups under SEM.
In group I , homogeneously long resin tags were arranged rather tight whereas rather loosely arranged resin tags of various length were found in group II Lateral branching of resin tags was the characteristic finding observed in group 2 .
