Shear bond strength of luting cements to fixed superstructure metal surfaces under various seating forces.

Purpose: In this study, the shear bond strengths (SBS) of luting cements to fixed superstructure metal surfaces under various seating forces were investigated.

Materials And Methods: Seven different cements [Polycarboxylate (PCC), Glass-Ionomer (GIC), Zinc phospahate (ZPC), Self-adhesive resin (RXU), Resin (C&B), and Temporary cements ((RXT) and (TCS))] were bonded to a total number of 224 square blocks (5×5×3 mm) made of one pure metal [Titanium (CP Ti) and two metal alloys [Gold-Platinum (Au-Pt) and Cobalt-Chrome (Co-Cr)] under 10 N and 50 N seating forces. SBS values were determined and data were analyzed with 3-way ANOVA.

Curing efficiency of dual-cure resin cement under zirconia with two different light curing units.

Purpose: Adequate polymerization is a crucial factor in obtaining optimal physical properties and a satisfying clinical performance from composite resin materials. The aim of this study was to evaluate the polymerization efficiency of dual-cure resin cement cured with two different light curing units under zirconia structures having differing thicknesses.

Materials And Methods: 4 zirconia discs framework in 4 mm diameter and in 0.

Polymerization efficiency of two dual-cure cements through dental ceramics.

Purpose: The aim of this study was to evaluate the effect of thickness of zirconia on curing efficiency of resin cements.

Materials And Methods: Four discs with 4.0 mm in diameter were prepared from non-HIP translucent zirconia blocks using a CAD/CAM system and feldspathic ceramic was layered onto discs.

Finite element analysis of heat generation from different light-polymerization sources during cementation of all-ceramic crowns.

Statement Of Problem: Exothermic composite resin chemical reactions and visible light generators can produce heat during a restorative polymerization process. These thermal changes in restored teeth may cause pain and irreversible pulpitis.

Purpose: The purpose of this study was to analyze the temperature distribution and heat flow patterns of a crowned mandibular second premolar tooth model using 3 different light-polymerization technologies and a finite element technique.

Dental anxiety among adults in Turkey.

Aim: This aim of this study was to investigate the prevalence of dental anxiety and related factors in a Turkish population.

Methods And Materials: The Turkish translation of the Dental Fear Scale (DFS) and the Modified Dental Anxiety Scale (MDAS) were administered to 115 dental patients consisting of 21 subjects who had dental phobia and of 94 patients who did not. The scales were also administered to a non-clinical general population (N=183).

Reliability and validity of the Modified Dental Anxiety Scale (MDAS) in a Turkish population.

Objectives: Fear of dentistry is a common obstacle to obtaining dental care in Turkey. The aim of this study was to assess the reliability, validity and psychometric characteristics of the Turkish translation of the Modified Dental Anxiety Scale (MDAS) and compare it to the Dental Fear Survey (DFS) scores obtained in the same population.

Methods: The Turkish translated version of the MDAS was administered to 115 dental patients; 21 subjects who suffered from dental phobia, requiring general anesthesia for dental procedures, and 94 who did not have dental anxiety, in addition to 442 subjects from the general population.

ITI implants and Dolder bars in the treatment of large traumatic defect of mandible: a clinical report.

The development of more sophisticated implant techniques to produce satisfying results improves the precise planning of both the surgical phase of the implantation and the following prosthetic rehabilitation. Ball and bar attachments are the main retainer systems for implant-bearing overdentures to achieve a successful treatment in the partial or full edentulism. In this clinical report, a 23-year-old male patient, presented with a large traumatic defect in the anterior mandible, was treated with ITI implant and ITI Dolder bar combinations.
