Long-term fracture load of all-ceramic crowns: Effects of veneering ceramic thickness, application techniques, and cooling protocol.

BACKGROUND: To evaluate, in vitro, the effects of the cooling protocol, application technique, and veneering ceramic thickness on the fracture resistance of ceramic crowns with Y-TZP frameworks. MATERIAL AND METHODS: 80 frameworks were made from zirconia by the CAD/CAM technique and divided into 8 groups (n = 10) according to the factors: "application technique" (stratified-L and pressed -P), "thickness" (1 mm and 2 mm), and "cooling protocol" (slow-S and fast-F) of the feldspathic veneering ceramic. After, all crowns were cemented over G10 preparations with resin cement (Panavia F, Kuraray), mechanically cycled (2x106 cycles, 200 N, 3Hz), and subjected to the axial compression resistance test (0.5 mm/min, 10 kN). The data (N) underwent descriptive statistical analysis by 3-way ANOVA and Tukey's test (5%). Fracture analysis was performed to determine the possible origin of failure. RESULTS: The factors "cooling protocol" (P=0.0058) and "application" technique (P=0.0001) influenced the fracture resistance of the crowns. For pressed veneer technique, the P2S (4608.9±464.5). A presented significantly higher results than that P2F(3621.1±523.0)BCD (Tukey's test). For the stratified technique, this difference was not observed (P>0.05). The thickness of the veneering ceramic was not significant regardless of the cooling protocol and technique (P>0.05). The predominant failure mode was chipping of the ceramic veneer originating in the subsurface. CONCLUSIONS: The pressed technique, used with a slow-cooling protocol, leads to the best outcome for the veneering of all-ceramic crowns. Key words:Zirconia, ceramics, cooling protocol, thickness, application technique.

Influence of alveolar bone level on the pull-out bond strength of fiber-reinforced composite posts to root dentin.

This in vitro study evaluated the influence of alveolar bone level and type of cement on pull-out bond strength between different fiber-reinforced composite (FRC) posts and root dentin. Sixty bovine teeth were sectioned, and their root canals were prepared. The specimens were divided into 6 groups (n = 10) according to 2 factors: alveolar bone level and type of cement. Each root was embedded in acrylic resin to the depth of 7, 10, or 14 mm, simulating different alveolar bone levels. After the FRC posts were treated with 37% phosphoric acid and silane was applied, they were cemented with either a conventional resin cement or a self-adhesive resin cement and subjected to mechanical cycling. The results indicated that neither the alveolar bone level nor the type of cement played a significant role in the pull-out bond strength of the FRC posts to root dentin. Therefore, it is concluded that conventional and self-adhesive resin cements can be used to lute FRC posts to tooth roots, even in the presence of significant alveolar bone resorption.

Objective: To evaluate the prevalence of temporomandibular disorder in non-institutionalized elderly. Methods: A cross sectional analytical study, developed with non-institutionalized elderly, aged over 60 years, registered in the Family’s Health Program of Areia, Paraiba, Brazil for the period January to June 2013, when the study was conducted. The Anamnesic Index of Fonseca (DMF) was used as a tool for collecting the data. Results: Most seniors were female (63.0%) aged between 60 and 69 years (46.3%) and married (53.6%). 59.7 % were illiterate, and the most of them retired (87.6%) with incomes up to minimum wage (86.3%). There was a significant association between the prevalence of TMD and the variables of gender, education and income. The TMD was more prevalent in females (49%), among the illiterates (49.9%) and among those who had an income of a minimum wage (49.1%). The degree of severity of dysfunction had a significant association with marital status (p = 0.011) and income (p = 0.036). The percentage of elderly with mild TMD was higher among unmarried (78.4 %) and among those who had income above the minimum wage (85.2%). It was also observed that the percentage of seniors with moderate TMD was higher among those who were divorced (37.9%) and among those who had an income up to the minimum wage (21.1%) happening similarly on the observed about severe TMD (6.6%). Conclusion: It can be seen that, in elderly patients studied, the prevalence of TMD with mild degree of severity was high, reaching more often women. (AU)

Finite element analysis of the influence of geometry and design of zirconia crowns on stress distribution.

PURPOSE: To evaluate the influence of the geometry and design of prosthetic crown preparations on stress distribution in compression tests, using finite element analysis (FEA). MATERIALS AND METHODS: Six combinations of 3D drawings of all-ceramic crowns (yttria-stabilized zirconia framework and porcelain veneer) were evaluated: F, flat preparation and simplified crown; FC, flat preparation and crown with contact point; FCM, flat preparation and modified crown; A, anatomical preparation and simplified anatomical crown framework; AC, anatomical preparation and crown with contact point; and ACM, anatomical preparation and modified crown. Bonded contact types at all interfaces with the mesh were assigned, and the material properties used were according to the literature. A 200 N vertical load was applied at the center of each model. The maximum principal stresses were quantitatively and qualitatively analyzed. RESULTS: The highest values of tensile stress were observed at the interface between the ceramics in the region under the load application for the simplified models (F and A). Reductions in stress values were observed for the model with the anatomical preparation and modified infrastructure (ACM). The stress distribution in the flat models was similar to that of their respective anatomical models. CONCLUSIONS: The modified design of the zirconia coping reduces the stress concentration at the interface with the veneer ceramic, and the simplified preparation can exert a stress distribution similar to that of the anatomical preparation at and near the load point, when load is applied to the center of the crown.

Efeito de diferentes espessuras, técnicas de aplicação e protocolos de resfriamento na resistência à fratura da cerâmica de cobertura aplicada sobre infraestrutura de y-tzp / Effects of different thicknesses, application techniques, and cooling protocols on fracture resistance of a veneering ceramic applied to Y-TZP infrastructures

O objetivo desta pesquisa foi avaliar, in vitro, a influência do resfriamento, da técnica de aplicação e do efeito da espessura da cerâmica de cobertura na carga de fratura de coroas totalmente cerâmicas com infraestrutura de zircônia. Foram confeccionadas 100 infraestruturas de zircônia (Y-TZP) com 1,0 mm de espessura. 80 infraestruturas foram divididas em 8 grupos (n = 10) para confecção de 80 coroas de acordo com os fatores “técnica de aplicação” (estratificada e prensada), “espessura” (1 mm e 2 mm) e “protocolo de resfriamento” (lento e rápido) da cerâmica de cobertura. Com as outras 20 infraestruturas foram confeccionadas 20 coroas pela técnica CAD/CAM/Rapid Layer e divididas em 2 grupos (n = 10) de acordo com o fator “espessura da cerâmica de cobertura” (1 mm e 2 mm) e foi realizada Análise de Elementos Finitos. Todos os espécimes foram ciclados mecanicamente (200 N; 2 x 106 ciclos; 3,0 Hz; água/ 37 °C). A presença de chipping foi avaliada através de análise em estereomicroscópio após a ciclagem mecânica. Em seguida, todos os espécimes foram submetidos ao teste de resistência à fratura em compressão axial (0,5 mm/minuto; 10 kN). As coroas foram analisadas para determinar a possível origem da falha. Os dados (N) obtidos foram submetidos à análise estatística, com o Teste de Dunnett, teste t-Student, para a técnica CAD/CAM/Rapid Layer, e ANOVA 3-fatores e teste de Tukey para as demais técnicas. A carga de fratura das coroas confeccionadas pela técnica CAD/CAM/Rapid Layer, independente da espessura, foi menor em relação às outras duas técnicas (p < 0,05), mas houve diferença significativa entre as duas espessuras das coroas confeccionadas por esta técnica. Houve influência dos fatores resfriamento (p = 0,0058) e técnica de aplicação (p = 0,0001) na análise das técnicas estratificada e prensada. O resfriamento lento diferiu do resfriamento rápido na técnica prensada de aplicação da cerâmica, porém, esta diferença não foi ..

The aim of this study was to evaluate the in vitro influence of cooling protocols and application techniques and the effect of the thickness of veneering ceramics on the fracture resistance of prosthetic crowns. For this purpose, 100 ‘zirconia partially stabilized by yttrium oxide’ frameworks (1 mm thick) were made. Eighty frameworks were divided into 8 groups (n = 10) according to the application technique (stratified or pressed), thickness (1 or 2 mm), and the cooling protocol (slow or fast) of the veneering ceramic. With the remaining 20 frameworks, 20 crowns were prepared by the CAD/CAM/Rapid Layer technique and were divided into 2 groups (n = 10) according to the veneering ceramic thickness (1 or 2 mm); these were also evaluated by Finite Element Analysis. All specimens were mechanically cycled (200 N, 2 x 106 cycles; 3.0 Hz; water at 37 °C). Chipping presence was evaluated by stereomicroscopy after mechanical cycling. All specimens were tested for compressive strength (0.5 mm/minute; 10 kN). We analyzed crowns to determine the possible beginning of the failures. Data, in N, were statistically analyzed with Dunnett’s, t-test, 3-way ANOVA, and Tukey's tests. The fracture load of the CAD/CAM/Rapid Layer crowns was lower, regardless of ceramic thickness, when compared with the other two application techniques tested (p < 0.05). We observed an influence of the cooling protocol (p = 0.0058) and the application technique (p = 0.0001) in the analysis of stratified and pressed techniques. Slow cooling differed from rapid cooling in the pressed ceramic crowns; however, this difference was not observed for the stratified crowns, regardless of the thickness of the veneering ceramic. Failures in the CAD/CAM/Rapid Layer crowns began predominantly at the interface between the resin cement and veneering ceramic, resulting in delaminations of the veneering ceramic, while the other techniques showed chipping of the veneering ceramic beginning ..

Análisis in vitro de la micro dureza del esmalte dental humano expuesto al peróxido carbamida y sometido a la acción del flureto / In vitro analysis of the micro hardness of human enamel exposed to carbamide peroxide under the action of flureto

Este estudio analizó la micro dureza del esmalte dental humano expuesto al agente blanqueador peróxido de carbamida a 16%, con posterior aplicación, o no, de fluoreto de sodio a 2%. La muestra fue constituida por 20 dientes humanos, terceros molares inclusos de los cuales fueron confeccionados 20 especímenes divididos en 2 grupos: Grupo A compuesto por 10 especímenes que fueron clareados, Grupo B compuesto por 10 especímenes clareados y sometidos a la aplicación de fluoreto. Fueron tomadas las medidas iniciales y finales de micro dureza para los dos grupos. Después del análisis estadístico, los resultados demostraron que, para el Grupo A, el agente blanqueador no presentó una reducción estadísticamente significativa (p < 0,05) en la micro dureza del esmalte dental, ya para el Grupo B, el uso de fluoreto de sodio a 2% restauró completamente la micro dureza del esmalte. Se concluye que la técnica de blanqueamiento vital mediato con peróxido de carbamida a 16% es un tratamiento recomendado, pues aunque altere la micro dureza del esmalte, esa pérdida es revertida probablemente debido al efecto tapón de la saliva y al uso de fluoretos pos blanqueamiento

This study analyzed the microhardness of the human dental enamel exposed the brighten agent 16% carbamide peroxide, with and without application of 2% sodium flouride. The sample was established by twenty human tooth, intact third molars from which have been obtained twenty fractions of enamel and were made the specimens, these have been divided in two groups : Group A - composed by 10 specimens which were only brighten, Group B - composed by ten specimens brighten and submitted on the application of flouride. After the initial results of microhardness of the dental enamel, were made the final measures of microhardness from the specimens from the Groups A and B. After statistical analysis, the results demonstrating that to the Group A, the brighten agent it didn´t present a reduction significant estatistical (p < 0,05) on microhardness of the dental enamel, about the group B the use of 2% sodium flouride revamped entirely the microhardness of the enamel. We concluded that the technique of mediate vital bleaching with 16% carbamide peroxide is a recommended treatment, because even it affects the microhardness of the enamel, this waste is probably reverted due the tampon effect from saliva and the use of flouride after bleaching

Objetivos: Determinar e correlacionar o fluxo salivar total, xerostomia e sintomas de ansiedade e depressão em pacientes com Síndrome da Ardência Bucal (SAB), comparando com um Grupo controle igualado em idade e sexo. Métodos: Foram selecionadas 25 mulheres com SAB e25 sem SAB, no Serviço de Estomatologia - UFPB. Determinou-se o Fluxo Salivar em Repouso (FSR) e o Fluxo Salivar Estimulado (FSE), presença de xerostomia e aplicou-se Inventário de Depressão de Beck (IDB) e Inventário de Ansiedade Traço-Estado (IDATE). Foi realizada análise estatística descritiva e aplicados testes de Mann-Whitney, qui-quadrado e coeficiente de correlação de Pearson, considerando p < 0,05. Resultados: A média de idade no Grupo SAB foi 59 ± 13 anos e no controle 56 ± 11 anos. A média do FSR no Grupo SAB foi de 0,41 ± 0,27 mL.min elevado a -1 e, nocontrole, de 0,45 ± 0,35 mL.min elevado a 1, sem diferença estatisticamente significante (p = 0,907). A xerostomia foi referida por 64% das pacientes SAB e por 32% do Grupo controle, com diferença estatisticamente significante (p = 0,011). Quanto à intensidade dos sintomas analisados, no Grupo SAB, 32% das pacientes apresentavam depressão e, no controle, apenas 12%, com diferença estatisticamente significante (p = 0,001). A ansiedade elevada ou muito elevada foi observada em 40% das pacientes com SAB e em 16% do Grupo controle, havendo diferença estatisticamente significante (p = 0,048). Conclusão: Considerando-se os resultados, pôde-se concluir que: a taxa de fluxo salivar do Grupo SAB foi normal; a xerostomia foi mais prevalente no Grupo SAB e não teve relação com o fluxo nem com a condição psicológica; as pacientes com SAB apresentaram maior prevalência de sintomas de depressão e ansiedade do que as do Grupo controle.

Objective: The aim of this study was to determine and correlate salivary flow rate, xerostomia and symptoms of anxiety and depression in patients with Burning Mouth Syndrome (BMS), comparing with matched control Group. Methods: It was selected 25 women with BMS and 25 without, on the Oral Medicine Service/UFPB. Unstimulated salivary flow rate(USFR), stimulated salivary flow rate (SSFR) and xerostomia presence were determined. The Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI) were applied. Mann-Whitney, chi-square tests and Pearson's correlation coefficient were used to analyze thedata and were considered significant with P < 0.05. Results: The mean age of BMS Group was 59.2 ± 13.5 years old and 56.6 ± 11.7 years old on the control Group. The USFR average for the BMS Group was 0.41 ± 0.27 mL.min to the -1 power and control Group was 0.45 ± 0.35 mL.min to the -1 power, no statistically significant difference was found (p = 0.907). The xerostomia was reported by 64% of the BMS patients and 32% on the control Group, with a statistically significant difference (p = 0.011). 32% ofthe patients with BMS and 12% of controls showed depression, with a statistically significant difference (p = 0.001). The high anxiety level was observed on 40% of patients with BMS and 16% on control Group, occurring a statistically significant difference (p = 0.048). Conclusions: Considering the results it is possible to conclude: the xerostomia was most prevailed on the BMS Group, and had no relationship with the salivary flow rate neither with the psychological conditions; BMS patients show more prevalence of depression symptoms and anxiety than control's Group patients.
