Bond strength of ceramic or resin CAD-CAM laminate veneers.

Purpose: To compare the bond strength of ceramic or resin laminate veneers produced using computer assisted design/computer assisted machining (CAD-CAM).

Methods: 80 teeth were prepared for laminate veneer, and divided into eight groups of different CAD-CAM blocks in each group. Each group was restored with the manufacturers' recommended procedures.

Comparative Evaluation of Antimicrobial Efficacy and Fluoride Release of Seven Different Glass-Ionomer-Based Restorative Materials.

Purpose: The aim of this study was to evaluate one high-viscosity glass-ionomer cement (EQUIA/GC), two resin-modified glass ionomers (Fuji II LC/GC, Photac Fil Quick Aplicap/3M Oral Care), two traditional glass ionomers (Ketac Molar Easymix/3M, Fuji II/GC), and two compomers (Freedom/SDI, Dyract XP/Dentsply Sirona) through a comparison of fluoride release and antimicrobial effects.

Materials And Methods: A total of 210 samples were prepared, as 10 for each of the 7 materials for fluoride release and 20 for each material for the antimicrobial effect tests. To measure fluoride release, 5 ml distilled water and 5 ml TISAB II were added to the samples, which were then incubated at 37˚C.

The evaluation of the colour changes of traditional composites, ceramic blocks and cad/cam composites in different solutions.

Aims: The aim of this study is to investigate the color changes of three different traditional composites, one ceramic and two resin-based composites CAD/CAM blocks in different solutions.

Methods: The materials used in the study were CAD/CAM block containing lithium disilicate glass ceramic (Ivoclar), Vita Enamic containing resin (VITA), Lava Ultimate Block containing resin (3M ESPE), G-aenial anterior composite (GC,), Filtek™ Ultimate Universal composite (3M ESPE) and Clearfil Majesty Esthetic composite (Kuaray). As colouring solutions, red wine (Buzbaǧ), black tea (Lipton), coffee (Nescafe) and distilled water (EAU distillee) were used.

The evaluation of microleakage and fluoride release of different types of glass ionomer cements.

Background: The aim of this study was to evaluate six different glass ionomer cement (GIC)-based restorative materials through comparisons of microleakage and fluoride release.

Materials And Methods: For microleakage, 30 teeth were randomly separated into 6 groups of 5: Group 1 (Dyract: compomer), Group 2 (Freedom: compomer), Group 3 (Equia: high-viscosity glass ionomer cements), Group 4 (Fuji IX: resin-modified glass ionomer cement), Group 5 (Ketac Molar: traditional glass ionomer cement [TGIC]) and Group 6 (Voco: TGIC). For fluoride release of six different GIC-based restorative materials, standard samples were prepared of 4 mm thickness and 7 mm diameter.

Effect of the different finishing and polishing procedures on the surface roughness of three different posterior composite resins.

Finishing and polishing techniques have great importance on the long term success and aesthetics of the composite restorations. In this study it was aimed to examine the effect of three different posterior composites on surface texture with various finishing and polishing procedures. Three different posterior composites, Filtek P60, Clearfil Majesty Posterior and Cavex Quadent Posterior Dense, and three different finishing and polishing procedures diamond finishing burs, tungsten carbide burs and Sof-Lex discs were used in the study.

The reliability of microleakage studies using dog and bovine primary teeth instead of human primary teeth.

Aim: This was to investigate if dental restorations on human, dog and bovine primary teeth are equitable for microleakage analysis, and the respective marginal adaptation deficiency in in vitro conditions.

Materials And Methods: In order to determine the level of microleakage in Class V poly acid-modified composite restorations of human, dog and bovine primary teeth, samples were evaluated by dye-leakage method in sections of the inner area of the restorations.

Results: We found no leakage in 6 out of 10 (60%) human restorations, in 7 out of 10 (70%) of dog and in 7 out of 10 (70%) of bovine teeth.

Can exposure to manganese and extremely low frequency magnetic fields affect some important elements in the rat teeth?

Background: Length and level of exposure to electromagnetic fields (EMFs) is increasing in association with the widespread use of electrical and electronic devices and technological progress. The undesirable effects of extremely low frequency magnetic fields (ELF-MFs) on health have attracted considerable interest.

Materials And Methods: Sixty-four four-month-old male Wistar rats divided into eight groups of eight rats each were used.

An analysis of the aetiology, prevalence and clinical features of dentine hypersensitivity in a general dental population.

Aim: Dentine hypersensitivity may be defined as pain arising from exposed dentine typically in response to chemical, thermal or osmotic stimuli that cannot be explained as a rising from any other form of dental defect or pathology. The aim to this cross-sectional study was to determine prevalence of dentine hypersensitivity (DH) and to examine some associated etiological factors in a study of patients visiting general dental practitioners in Turkey.

Patients And Methods: A total of 1368 patients were examined for the presence of cervical dentine hypersensitivity by means of a questionnaire and intraoral tests by (air and probe stimuli).

Treatment of an amelogenesis imperfecta with restorations prepared using a modified clear matrix technique.

The rehabilitation of a patient with amelogenesis imperfecta (AI) from both functional and esthetic standpoints represents a challenge. A number of treatment options have been proposed. Recently, the use of adhesive restorations has gained popularity because of the improved physical properties of these materials.
