Effects of some important parameters like impactor effects, plug geometry and initiation points on bonding aluminum tubes to aluminum plugs were studied. The impact velocity and dynamic angle between tube and plug should be precisely managed to achieve an optimum bonding condition. A new explosive bonding technique with the use of two material impactors was proposed. Results are especially suit...

objective: the use of presently available dentin bonding systems has greatly reduced mi-croleakage; however, the ideal situation where the adhesive resin completely penetrates the demineralized dentin is not yet achieved. the purpose was to compare the microleak-age of fifth and sixth generation bonding agents at enamel and dentinal margins. materials and methods: class v cavities were prepared...

objectives : this experimental study evaluated the effect of bonding application time on the microshear bond strength of composite resin to different types of glass ionomer cements (gics). materials and methods: one-hundred and sixty specimens (two conventional and two resin-modified gics) were prepared and divided into 16 groups. the surface of all specimens was prepared using two different bo...

introdouction: esthetic demands of patients have led to the introduction of tooth-colored restorations wherecomposite resins are bonded to the enamel using acid etch techniques. total etch adhesion systems are still considered as the gold standard among bonding systems. however, clinicians have a tendency to use adhesive systems with simpler application procedures. the aim of the present study ...
