objectives: the aim of the study was to compare the effect of fifth and seventh generation bonding agent on sealant success. materials and methods: sixty-four school children aged six to nine years received sealants in four permanent molars in a split mouth design, such that each patient received sealant in the first permanent molar with fifth generation bonding agent in one arch and seventh ge...

• T g of the epoxy adhesive increased when was cured or post-cured at 50 °C. The increase in testing temperature produced a decrease mechanical properties. Compressive strength differently affected if curing below beyond . Tensile non-monotonic way for temperatures 20 Structural cold-curing adhesives are widely used to strengthen Reinforced Concrete (RC) structures with Fibre Polymers (FRPs). p...

Dental chair lights have been known to rapidly polymerize lightcured composites beyond the point of workability. Often in our dental clinics we are advised to switch off the dental chair light while light curing of dental composites. The purpose of this study was to determine whether the dental chair light causes any effect on the degree of polymerization of light cured composites using the qua...

objectives: this study aimed to compare the durability of four adhesive systems by assessing their microtensile bond strength (mtbs) and microleakage during six months of water storage. materials and methods: a total of 128 human third molars were used. the adhesives tested were scotch bond multipurpose (sbmp), single bond (sb), clearfil-se bond (cseb), and all-bond se (abse). after sample prep...

We describe the fabrication of a meatus obturator prosthesis made with visible light-cured (VLC) resin. The fabrication technique is relatively easy and saves time by eliminating some laboratory procedures for both the patient and the practitioner. The meatus obturator results in a more stable maxillary prosthesis and permits acceptable speech for patients using it.

The purpose of this study was to evaluate the Knoop hardness of a dual-cured resin-based luting cement irradiated with different light sources as well energy density through a ceramic sample. Three light-curing unit (LCUs) were tested: tungsten halogen light (HAL), light-emitting diode (LED) and xenon plasma-arc (PAC) lamp. Disc-shaped specimens were fabricated from a resin-based cement (Enforc...
