Abstract Introduction Some colorant foods and beverages cause undesired discoloration on dental restorations. The aim of this study was to investigate the effect whitening kinds toothpaste with different active ingredients color change resin‐based CAD/CAM blocks. Material methods In study, block samples sized 1.5 × 7 12 mm, were prepared. Then, simulate time‐dependent change, immersed in coffee (Nescafe Classic, Nestlé) for 14 days. After values colored measured by spectrophotometer, brushed...

Abstract Background Information on the current status of oral health and related risk factors is lacking in Turkiye. This study aimed to evaluate dental caries associated among Turkish population using findings third national survey. Methods cross‐sectional epidemiological survey was carried out between March September 2018 including five index ages age groups (5‐, 12‐, 15‐year‐olds, 35–44 65–74 groups). A multistage cluster sampling design used obtain a representative sample these groups....

3D-printed permanent resins have recently been introduced to produce restorations. The aim of this study is evaluate the effect surface treatment methods on shear-bond strength (SBS) between and adhesive cement.

The purpose of this study was to evaluate the effectiveness several surface protectors for a glass-ionomer, resin-modified and polyacid-modified resin cement by determining dye uptake spectrophotometrically. 378 samples, made up Ionofil U, Vitremer, Dyract, were prepared divided into groups seven each. Positive negative control specimens remained unprotected while experimental protected with Finishing Gloss, Protect-It, LC Varnish, Adper Single Bond, or nail varnish. positive controls...

The aim of our study is to assess the dose enhancement from scattered radiation due dental restorative materials used for occlusal and mesio-occlusal-distal (MOD) cavity filling during simulated head neck radiotherapy.We have studied ratio (DER) conventional amalgam, high-copper resin composite at cadaver mandible teeth using 2 therapeutic photon energies 1.25 MeV (Co-60 gamma ray) 6 MV (Linac X-ray) irradiation.DER values buccal position Co-60 X-ray were 1.250 ± 0.013 1.151 0.012,...

The aim of this study is to evaluate the amount microleakage resulting from application self-etch, selective etch, etch-and-rinse adhesive systems in class II cavities.Four with etch-and-rinse, etch and self methods were used on extracted teeth. All groups restored G-aenial A'CHORD (Nanohybrid) (GC, Tokyo, Japan) A2 composite. After 1000 thermal cycles applied teeth after restoration, samples kept 0.5% basic fuchsin for 24 hours. Microleakage values formed dye penetration determined...
