Influence of shade and light-curing distance on the degree of conversion and flexural strength of a dual-cure core build-up resin composite.

Purpose: To investigate the influence of shade and light-curing distance on the degree of conversion (DC) and flexural strength (FS) of a dual-cure core build-up resin composite.

Methods: 135 specimens were prepared and divided into three main groups according to the shade of the composite core material; dentin, blue and white shades. Each group was further subdivided into three subgroups according to the light-curing distance; 0 mm, 3 mm and 5 mm.

Immediate vs delayed repair bond strength of a nanohybrid resin composite.

Purpose: To evaluate both the immediate and water-stored repair tensile bond strength (TBS) of a nanohybrid resin composite using different bonding protocols.

Materials And Methods: One hundred sixty half hourglass-shaped slabs were prepared. Eighty half-slabs were wet ground immediately after light curing using high-speed abrasive burs, while the other half-slabs were stored in water for one month (delayed) and then wet ground for repair.

Effect of air-drying pressure and distance on microtensile bond strength of a self-etching adhesive.

Purpose: To investigate the effect of pressure and distance during air drying on the microtensile bond strength (μTBS) of a single-step self-etching adhesive to bovine dentin.

Materials And Methods: A total of 36 bovine molars was used in this study. Twenty-seven teeth were used for μTBS testing and 9 teeth for the evaluation of the resin/dentin interface.

The effect of the pre-conditioning step on the shear bond strength of nano-filled resin-modified glass-ionomer to dentin.

Objectives: The purpose of this study was to evaluate the effect of the pre-conditioning step using different dentin conditioners on the shear bond strength (SBS) of the nano-filled resin-modified glass ionomer (RMGI) to dentin.

Methods: Twenty-four human molars were used in this study. Subsequent to teeth sectioning in the mesio-distal direction and creation of the smear layer, the teeth were divided into six groups with and without the pre-conditioning step.

The outcome of immediate or delayed application of a single-step self-etch adhesive to coronal dentin following the application of different endodontic irrigants.

Objectives: The aim of this study was to evaluate the outcome of immediate or delayed bonding of a single-step self-etch adhesive to coronal dentin after the application of different endodontic irrigants.

Methods: Thirty five human molars were used. The coronal dentin was irrigated with either 0.

Tensile bond strength of immediately repaired anterior microfine hybrid restorative composite using nontrimmed hourglass specimens.

Purpose: To investigate the effect of different surface treatments on the tensile bond strength (TBS) of immediately repaired anterior microfine hybrid restorative composite using nontrimmed hourglass-shaped specimens.

Materials And Methods: Fifty-six nontrimmed hourglass composite specimens were prepared in this study. Eight specimens were used for the evaluation of the cohesive tensile strength as the control group.

Shear bond strength of glass-ionomer adhesive to dentin: effect of smear layer thickness and different dentin conditioners.

Purpose: To investigate the effect of two different smear layer thicknesses treated with different dentin conditioners on the bond strength of glass-ionomer adhesive to dentin.

Materials And Methods: Fifty human molars were used. Each tooth was sectioned in a mesiodistal direction into halves, using a low-speed diamond disk.

Effect acidic and alkaline/heat treatments on the bond strength of different luting cements to commercially pure titanium.

Objective: The purpose of this study was to characterize the effects of either acidic or combined alkaline/heat treatments on the surface of grit-blasted commercially pure (cp) titanium. The effects of the previous treatments on the shear bond strength (SBS) of cp titanium to conventional glass ionomer, resin-reinforced glass ionomer and self-adhesive resin luting cements were evaluated.

Methods: Titanium discs were machined and received one of the following treatments; grit-blasting (GB), grit-blasting followed either by etching in HNO(3)/HF solution (GB/Ac) or by combined 5M NaOH treatment/heat treatment at 600 degrees C for 1h, then immersed for 24h in SBF solution before cementation (GB/Ak).

Effect of surface treatments on the tensile bond strength of repaired water-aged anterior restorative micro-fine hybrid resin composite.

Objectives: The purpose of this study was to characterize changes in surface topography associated with different surface treatments and their effect on tensile bond strength (TBS) of repaired water-aged anterior restorative micro-fine hybrid resin composite.

Methods: The TBS of repaired resin-based composite slabs either non-treated or exposed to different mechanical and/or chemical surface treatment procedures were measured. The cohesive tensile strength of non-repaired intact slabs was used as a control group.

Sodium hypochlorite as dentin pretreatment for etch-and-rinse single-bottle and two-step self-etching adhesives: atomic force microscope and tensile bond strength evaluation.

Purpose: The aim of this study was to evaluate the effect of using 5.25% commercial sodium hypochlorite treatment prior to the application of etch-and-rinse and self-etching adhesives on dentin surface microtopography and tensile bond strength.

Materials And Methods: Thirty-two noncarious, nonrestored human third molars were collected.

Reattachment of a severely traumatized maxillary central incisor, one-year clinical evaluation: a case report.

Traumatic fracture of anterior teeth is one of the common dilemmas facing the dentist during daily practice. Classical treatment of a fractured tooth involving the pulp includes the use of post and core with or without a crown, or extraction of the remaining part of the fractured tooth and replacement with a three-unit fixed partial denture or an implant. With the improvement of adhesive systems, reattachment of the fractured tooth fragment became possible as a mode of treatment that immediately improves the esthetic quality of the restored tooth.
