Effect of different surface treatment protocols on the bond strength between lithium disilicate and resin cements.

Because the use of hydrofluoric acid (HF) poses health risks if handled improperly, many clinicians prefer to have the ceramic restorations pre-etched in dental laboratories. However, during the try-in procedure, the pre-etched glass-ceramic restorations may be contaminated with saliva resulting in reduced bond strength. This in-vitro study aimed to investigate the effect of different surface treatments on the bond strength of lithium disilicate (LD) glass-ceramic restorations (IPS e.max Press, Ivoclar Vivadent) to two resin cements. One-hundred eighty blocks (4X4X3mm) of LD glass-ceramic were divided into twelve groups (n = 15), of which six received Variolink Esthetic DC (VE) cement and six received RelyX Ultimate (RU) cement, following the surface treatments: G1) Control: Hydrofluoric Acid + Silane (HF + Sil); G2) Hydrofluoric Acid + Saliva + Silane (HF + S + Sil); G3) Hydrofluoric Acid + Saliva + Ivoclean + Silane (HF + S + IC + Sil); G4) Hydrofluoric Acid + Saliva + Phosphoric Acid + Silane (HF + S + P + Sil); G5) Hydrofluoric Acid + Saliva + Monobond Etch & Prime (HF + S + EP); G6) Monobond Etch & Prime (EP). Following treatment, a resin-cement cylinder (2.3 mm diameter) was built on the glass-ceramic surface, photocured (20 s), stored in distilled water (37 °C, 24 h) and submitted to the shear bond strength test. Bond strength data (MPa) were subjected to two-way ANOVA and Tukey (α = 0.01). Cement type and surface treatment had a significant effect on the bond strength (p < 0.001) (Table 4). Single-step Monobond Etch & Prime (EP) significantly improved the bond strength of resin-cements to glass-ceramic with and without saliva contamination.

Evaluation of the Mechanical Properties of Three Resin-Modified Glass-Ionomer Materials.

This study is aimed at evaluating the flexural strength (FS), fracture toughness (FT), and diametral tensile strength (DTS) of three resin-modified glass-ionomer cements (RMGICs): Ketac Nano, Riva Light Cure, and Fuji II LC. One hundred twenty specimens were prepared from the RMGIC materials (n = 10). The cements were mixed and inserted into different mould sizes according to the test performed: FS: rectangular Teflon mould (32 mm × 3.15 mm × 2 mm); FT: notchless triangular prism (NTP) Teflon mould (6 mm × 6 mm × 6 mm × 12 mm); and DTS: ring road stainless steel mould (6 mm × 3 mm). Specimens were light cured for 20 seconds on each surface and stored in distilled water at 37°C ± 2°C for seven days prior to tests. To evaluate the influence of storage in the mechanical properties of the RMGIs, specimens tested for DTS were stored in distilled water at 37°C ± 2°C for 32 days prior to test. Data were analyzed by ANOVA and Tukey's test (α = 0.05). Fuji II LC presented significantly higher values for all tests employed when compared to Ketac Nano and Riva LC RMGIs. There was no significant difference on DTS before and after the 32-day storage for each material. Fuji II LC presented superior mechanical properties when compared to Ketac Nano, and Riva LC storage showed no influence on the mechanical properties of the RMGI materials tested.

Surface Roughness of Methacrylate- and Silorane-Based Composites After Finishing and Polishing Procedures.

OBJECTIVE: To compare the effect of surface finishing and polishing protocols on the surface roughness (Ra) of methacrylate-based and silorane-based resin composites. METHODS AND MATERIALS: Fifty specimens (5 mm x 2 mm) of each composite material were prepared using a split mold: Filtek™ Supreme Ultra (3M ESPE), Tetric EvoCeram® (Ivoclar Vivadent), Tetric Ceram™ HB (Ivoclar Vivadent), and Filtek™ LS Low Shrink (3M ESPE). Specimens were divided into five groups (n = 10) according to the following procedures: G1 - 15-µm fine diamond bur (FDB); G2 - 15-µm FDB followed by a 20-fluted tungsten carbide bur; G3 - 15-µm FDB followed by diamond-impregnated micropolishing points (D-FINE Double Diamond Polishing System, Clinician's Choice); G4 - 15-µm FDB followed by diamond-impregnated micropolishing points (Flame Point Pre-polisher and Shine, Brassseler USA); and G5 - 15-µm FDB followed by the application of a surface sealer (PermaSeal®, Ultradent Products, Inc.). Ra was measured in three different regions using a surface profilometer (Mitutoyo Surfest SJ-210, Mitutoyo America). RESULTS: Multiple comparisons were obtained using a one-way ANOVA with Tukey's B rank order test ( = 0.05). No significant differences in Ra were observed among the resin composites tested in the same condition. The use of a FDB generated the highest roughness values, while the use of a surface sealer resulted in the lowest roughness values for all resin composites tested (P < .05). No significant difference in Ra was observed between the use of a multi-fluted carbide bur and the rubber point D-FINE Double Diamond Polishing System for all resin composites tested.

Effect of surface treatments on the bond strength of self-etching adhesive agents to dentin.

The aim of this study was to investigate the influence of different surface treatments on the shear bond strength (SBS) of self-etching adhesive systems to dentin. Ninety freshly extracted noncarious human molars were sectioned mesiodistally and embedded in chemically cured resin with the buccal or lingual surfaces facing upward. Superficial dentin was exposed, and specimens were randomly assigned to 3 groups, according to the self-etching adhesive system utilized: Clearfil SE Bond (2-step), Scotchbond Universal (1-step), and Clearfil S³ Bond Plus (1-step). These groups were assigned to 5 subgroups (n = 12), according to the following treatments: G1, distilled water (control); G2, 35% phosphoric acid gel; G3, ultrasonic vibration; G4, sandblasting; G5, pumice slurry. For the 1-step self-etching adhesives, no significant differences in SBS values were observed between the different surface treatment groups and their control subgroup (P > 0.05). For the 2-step adhesive, mean values were significantly higher in the ultrasonic vibration and pumice-treated groups than in the control subgroup (P < 0.05). Overall, the use of vibration resulted in superior mean SBS values to dentin for all adhesives tested, although the values were not always significantly higher.

Effect of artificial aging on the surface roughness and microhardness of resin-based materials.

This study sought to verify the effects of aging on the surface roughness (Ra) and microhardness (Knoop hardness number [KHN]) of resin-based restorative materials protected with a surface sealer. Disc specimens of 2 resin-modified glass ionomers (RMGIs) and 1 composite resin (CR) were fabricated in a metal mold. Specimens of each material were divided into 1 group that was covered with surface sealer and 1 group that was not. Both groups of each material were then subdivided according to whether they were stored (aged) in cola or distilled water. Surface roughness and KHN values were obtained from each specimen before and after storage. After aging of the specimens, significantly higher Ra values were observed in the 2 RMGIs when they were not covered with a surface sealer, while the CR was not affected. The KHN values varied by materials and storage conditions (with and without a surface sealer). All the groups with a surface sealer exhibited increased Ra values after aging.

A split-mouth randomized clinical trial of conventional and heavy flowable composites in class II restorations.

OBJECTIVE: The aim of this study was to evaluate the 2-year clinical performance of class II restorations made with a composite resin with two different viscosities. METHODS: 47 patients received two class II restorations (n=94), one made with GrandioSO (conventional viscosity - CV), and the other with GrandioSO Heavy Flow (flowable viscosity - FV), subjecting both materials to the same clinical conditions. The self-etching adhesive Futurabond M was used for all restorations. The composites were inserted using the incremental technique. The restorations were evaluated using the modified USPHS criteria according to the periods: baseline, 6 months, 1 year and 2 years after restorative procedures. RESULTS: After 24 months, 40 patients attended the recall and 78 restorations were evaluated. In all periods, no secondary caries was observed. After 6 months, there were slightly overall changes of scores for most parameters. After 24 months, the higher number of changes from score Alfa to Bravo was observed for marginal discolouration (32.5% - CV and 39.5% - FV) and colour match (15% - CV and 31.6% - FV), followed by proximal contact (25% - CV and 23.7% - FV) and marginal adaptation (20% - CV and 21.1% - FV). For wear, surface texture and postoperative sensitivity the changes were very small. Just two restorations were lost during the 24-month follow up. Less than 5% of all restorations showed postoperative sensitivity. Chi-square test showed no significant differences between the two materials for all parameters analysed. CONCLUSION: After 2 years of clinical service, no significant differences were observed between GrandioSO conventional and GrandioSO Heavy Flow for the parameters analysed. Both materials provided acceptable clinical behaviour in class II restorations. CLINICAL SIGNIFICANCE: This study presents the possibility of using a flowable composite with high filler content, for performing class II restorations.

A Metodologia da Problematização como uma alternativa de abordagem de ensino aprendizagem na disciplina de didática aplicada ao ensino superior do programa de pós-graduação em odontologia restauradora: Arco de Maguerez / A The Methodology of Problematization as an alternative learning approach to teaching in the Department of Applied Teaching Higher Education's graduate program in Restorative Dentistry: Arch Maguerez

Avaliou-se a Metodologia da Problematização (Arco de Maguerez) como alternativa de abordagem de ensino aprendizagem na Disciplina de Didática Aplicada ao Ensino Superior do Programa de Pós-graduação em Odontologia Restauradora. Para isto, contou-se com a participação dos alunos mestrandos e doutorandos do Programa de Odontologia Restauradora da Faculdade de Odontologia de São José dos Campos. Em seguida foi selecionado os temas que deveriam fazer parte do conteúdo curricular e do cotidiano do futuro docente de odontologia. Após a seleção dos temas foram montadas duas abordagens de metodologia de ensino-aprendizagem: uma baseada na metodologia de ensino aplicada atualmente na disciplina (dita tradicional); outra baseada na Metodologia da Problematização (MP) (Arco de Maguerez), que foram passadas para os alunos em dois momentos. Simultaneamente foi formulado um questionário para que os alunos respondessem sobre suas percepções acerca das duas abordagens didáticas, com o objetivo de avaliar o grau de significância dos métodos de ensino aplicados, realizando, posteriormente, uma análise comparativa entre os dois métodos. Os questionários foram então avaliados e suas respostas foram utilizadas para registrar a efetividade e falhas destas metodologias. O resultado mostrou que a Metodologia da Problematização baseada no Arco de Charles Maguerez se apresentou válida na formação dos alunos da pós-graduação e que as duas metodologias se complementam na transmissão do conhecimento, sendo a MP uma ferramenta inovadora nesse processo
