These studies claim that a certain waiting period is needed prior to restoration to reach the original bond strength values prior to bleaching. This study determined the effect of anti-oxidant applications on the bond strength values of resin composites to bleached dentin. Ninety human teeth extracted for orthodontic purposes were used in this study. The labial surface of each tooth was ground and flattened until dentin appeared. The polished surfaces were subjected to nine different treatments: 1) bleaching with gel (35% Rembrandt Virtuoso); 2) bleaching with gel + 10% sodium ascorbate (SA); 3) bleaching with gel + 10% butylhydroxyanisole (BHA); 4) bleaching with sol (35% hydrogen peroxide); 5) bleaching with sol + 10% sodium ascorbate; 6) bleaching with sol + 10% BHA; 7) bleaching with gel + immersed in arti...

Material and Method: Sixty specimens were prepared standard metallic mold (25x2x2 mm) prepared according to ISO 4049 for flexural strength. The specimens were divided into four groups (n: 15) as follows; Flowable (Filtek Flow) + nanofil composite (Filtek Supreme) (Gr I), nanofil composite (Gr II), Flowable +woven glass fiber (EverStick Net) + nanofil composite (Gr III), woven glass fiber + nanofil composite (Gr IV).The specimens were stored in distilled water at 370 C for 24 hour, thenevaluated with three-point bending test using Universal Testing Machine. Data were analysed using Kruskall Wallis and Mann Whitney U tests. Three samples from each group were examined by SEM. Result:The mean flexural strength values of the groups I, II, III and IV were 93.6±4, 85.5±6, 107±9 and 101±5 respectively. Glass fiber-reinforced nanofil composite applied with flowable composite (Gr III) exhibited higher flexural strength values in comparison to the other groups (p<0.05 While control group (Gr II) exhibited the lowest). Significant differences were found between flexural strength of control and the other groups (p<0.05). In SEM evaluation, it was detected that in fiber-reinforced groups (Groups III and IV) fractured area was limited by the fiber in the stressed region. Conclusion: Within the limitations of this in vitro study it is concluded that glass fiber reinforcement improves the flexural strength of the nanofill composite. In SEM evaluation after fracturing, glassfiber reinforcement prevented crack propagation. Key Words: Composite resin, fiberreinforcement, flexural strength, scanning electron microscope

Yöntem: Çalışmada 20 adet yeni çekilmiş insan dişi kullanıldı. Kuartz tungsten halojen ışık kaynağı, LED ışık kaynağı ve diode Lazer ışık kaynağı kullanılarak beyazlatma ajanı (%36 H2O2) varlığında ve yokluğunda olmak üzere dişler 15 dakika boyunca ışığa maruz bırakıldı ve oluşan pulpa odası sıcaklık artışları kaydedildi. Veriler Paired Simple test, Univariate Analysis of Varianca (ANOVA), Dependet Variable Test ve Tukey ' s honestly significant difference (HSD) ile istatistiksel olarak analiz edildi. Bulgular: Diode lazer ışık kaynağı en yüksek ışı artışına neden oldu. LED ışık kaynağı ise en düşük ısı artışına neden oldu. İstatistiksel analizler ışık kaynakları arasında, sıcaklık artışında istatistiksel olarak anlamlı derecede farklılık olduğunu gösterdi (P=.000). Sonuç: Araştırmamıza göre, LED ve halojen ışık kaynakları pulpada ısı artışına neden olmuştur fakat bu artış pulpa dokusunda geri dönüşümsüz zararlı değişikliğe neden olacak seviyede değildir. Fakat, diode lazer ışık kaynağı kullanıldığında fazla ısı artışı olabilmesi nedeniyle dikkatli olunması gerekir. Bu sonuçlar, diş tiplerinden ve beyazlatma ajanı varlığından etkilememiştir.

The main clinical characteristics are extensive loss of tooth tissue, poor esthetics, and tooth sensitivity. Transmission of the gene takes place by either autosomal, dominant X-linked, or recessive modes. This clinical report describes a treatment sequence based on a multidisciplinary approach. A 21-year-old girl with hypoplastic amelogenesis imperfecta was referred to the Ege University School of Dentistry clinic. She was concerned about the poor appearance and sensitivity of her teeth. The patient presented with an anterior open bite, although orthodontic treatment had been completed previously. Periodontal gingivectomy of her posterior teeth followed by endodontic treatment where indicated was proposed. The prosthodontic treatment consisted of metal ceramic fixed partial dentures of precious alloy. At the end of treatment, function and esthetics were impr...

New and used gloves were included. All of the gloves were examined visually and then subjected to an air leakage test, an electrical test, and a microbiologic test. Permeability was evaluated independently by two researchers in a blind manner. Statistical analysis showed that there were no significant differences among the three brands of gloves or with respect to the usage periods, according to visual inspection and the air leakage test. Conversely, there were significant differences among each of the three brands of gloves and with respect to usage periods, according to the electrical and microbiologic tests.

Yöntem: Çalışmada 20 adet yeni çekilmiş insan dişi kullanıldı. Kuartz tungsten halojen ışık kaynağı, LED ışık kaynağı ve diode Lazer ışık kaynağı kullanılarak beyazlatma ajanı (%36 H2O2) varlığında ve yokluğunda olmak üzere dişler 15 dakika boyunca ışığa maruz bırakıldı ve oluşan pulpa odası sıcaklık artışları kaydedildi. Veriler Paired Simple test, Univariate Analysis of Varianca (ANOVA), Dependet Variable Test ve Tukey ' s honestly significant difference (HSD) ile istatistiksel olarak analiz edildi. Bulgular: Diode lazer ışık kaynağı en yüksek ışı artışına neden oldu. LED ışık kaynağı ise en düşük ısı artışına neden oldu. İstatistiksel analizler ışık kaynakları arasında, sıcaklık artışında istatistiksel olarak anlamlı derecede farklılık olduğunu gösterdi (P=.000). Sonuç: Araştırmamıza göre, LED ve halojen ışık kaynakları pulpada ısı artışına neden olmuştur fakat bu artış pulpa dokusunda geri dönüşümsüz zararlı değişikliğe neden olacak seviyede değildir. Fakat, diode lazer ışık kaynağı kullanıldığında fazla ısı artışı olabilmesi nedeniyle dikkatli olunması gerekir. Bu sonuçlar, diş tiplerinden ve beyazlatma ajanı varlığından etkilememiştir.
