    Abstract: Aim: Although bulk fill composites have been widely used as restorative material, there is no consensus regarding the best clinical protocol in terms of composite technique and adhesive system. Therefore, this clinical trial evaluated the clinical performance of bulk fill composites for class I restorations under different protocols. Methods: A randomized clinical trial including 155 class I restorations was conducted using different adhesive systems: conventional technique (phosphoric acid + conventional three-step adhesive system) (Group 1, 2 and 3); or self-etching adhesive system (Groups 4, 5 and 6). Control groups 1 and 4 were restored with conventional composite; groups 2 and 5 with low viscosity bulk fill and conventional composite as occlusal coverage; groups 3 and 6 with high viscosity bulk fill. The FDI criteria was used for clinical evaluation at baseline and after 6 months. Results: All groups showed good clinical performance. At baseline, the adhesive system did not affect postoperative hypersensitivity. After 6 months, group 5 showed a significant reduction in color and translucency; group 6 a reduction in terms of anatomical form and for postoperative sensitivity and an improvement in patient satisfaction (p 〈 0.05). Considering the same restorative technique, the use of the self-etching adhesive system showed a significant decrease in color and translucency (p 〈 0.05). Conclusion: All groups showed favorable clinical performance, and promising results were found for the conventional adhesive system and high viscosity bulk fill protocol.

    Abstract: To evaluate the microtensile bond strength (µTBS) of two resin cements to 3D printed and milled CAD/CAM resins used for provisional fixed partial dentures. Blocks (5 x 5 x 5 mm) of three 3D-printed resins (Cosmos3DTemp / Yller; Resilab3D Temp / Wilcos and SmartPrint BioTemp, / MMTech) were printed (Photon, Anycubic Technology Co.). A milled material (VitaCAD-Temp, VITA) was used as control. Half the specimens were sandblasted and the rest were untreated. Two blocks were bonded with the corresponding resin cement: PanaviaV5 (Kuraray Noritake) and RelyX Ultimate (3M Oral Care). After 24 hours, the bonded blocks were sectioned into 1 x 1 mm side sticks. Half the beams were tested for µTBS and the other half was thermocycled (5000 cycles, 30s dwell-time, 5s transfer time) before µTBS testing. A four way Generalized Linear Model (material*sandblasting*cement*aging) analysis was applied. VITA exhibited the lowest µTBS, regardless of the cement, sandblasting and thermocycling. Sandblasting significantly improved the µTBS of VIT, especially after aging, but did not improve the µTBS of 3D printed resins. Sandblasting was not beneficial for 3D printed resins, although is crucial for adhesive cementation of milled temporary resins. Airborne particle abrasion affects the integrity of 3D-printed resins, without producing a benefit on the microtensile bond strength of these materials. However, sandblasting is crucial to achieve a high bond strength on milled temporary resins.

    Abstract: Os laminados cerâmicos são restaurações indiretas ultraconservadoras, que requerem mínimo ou nenhum preparo (espessuras entre 0,2 e 0,5mm). Eles são capazes de reproduzir os aspectos naturais dos dentes e a longevidade clínica é determinada pela força de adesão formada entre superfície dental, cimento resinoso fotoativado e material cerâmico. Assim, o presente caso clínico relata a substituição de laminados cerâmicos insatisfatórios após 7 anos de uso. Inicialmente, foi realizada documentação fotográfica, moldagem inicial, enceramento diagnóstico e mock-up, para um correto planejamento. Após o consentimento e aprovação do paciente sobre o tratamento proposto, os laminados cerâmicos antigos foram removidos e preparos dentais com técnicas minimamente invasivas foram realizados, seguidos de moldagem definitiva com silicone por adição. Laminados cerâmicos à base de dissilicato de lítio injetado foram confeccionados em laboratório dos dentes 13, 12, 11, 21, 22 e 23. Na sessão seguinte, as adaptações proximais e cervicais foram checadas previamente, bem como a relação com os tecidos periodontais, assimetrias e a cor do cimento resinoso fotoativado. As superfícies dos dentes e laminados cerâmicos foram tratadas, antes da cimentação, de acordo com as recomendações dos fabricantes dos materiais. O cimento foi inserido na face interna dos laminados cerâmicos que, em seguida, foram posicionados e os excessos de material, removidos com pincel e fio dental. Ao final, cada superfície foi fotoativada por 40 segundos, usando um fotoativador LED. Após a cimentação de todos os laminados cerâmicos, foram realizados os ajustes oclusais, acabamento e polimento necessários. Portanto, o conhecimento, observação e aplicação de critérios estéticos, funcionais e biológicos são essenciais para adquirir o sucesso e a longevidade de uma reabilitação.

    Abstract: Abstract The scope of this study was to evaluate dissatisfaction with dental services among dentate and edentulous elderly Brazilians and its association with contextual and individual variables. The data from the National Oral Health Survey conducted in 2010 and contextual variables related to cities were used. Descriptive, bivariate and multilevel analysis was conducted among 1,989 elderly individuals. Of these, 11.2% of dentate and 22.1% of edentulous elderly people were dissatisfied. Among the dentate individuals, dissatisfaction was associated with contextual variables (location of municipality, human development index, GINI Index, the presence of Dental Specialty Centers and the coverage of oral health in public service) and persons related to health care and oral health conditions. For the edentulous individuals, no associated contextual variables were identified. Only the motive for the use of the service and satisfaction with teeth and mouth were associated with dissatisfaction with dental services. A considerable prevalence of dissatisfaction with the services was identified, being higher among edentulous elderly Brazilians. Among dentate elderly Brazilians, an association with contextual variables was detected.

    Abstract: Resumo O fluoreto presente em dentifrícios de 1,100 µg/g é considerado efetivo no controle de cárie dental. No entanto, sob alto desafio cariogênico devido ao aumento da exposição ao açúcar, maior concentração de fluoreto (5.000 µg/g) poderia ser necessária para compensar o desequilíbrio no processo de cárie. Isso foi testado em um modelo de ciclagens de pH, que avaliou o efeito da concentração do fluoreto, relacionada ao dentifrício, na redução da desmineralização do esmalte dental sob condição de dois níveis de desafio cariogênico. Blocos de esmalte (n=20) foram submetidos a dois regimes de ciclagens de pH, simulando 8 e 16 exposições diárias ao açúcar, e foram tratados com soluções contendo: 0 (sem flúor), 275 ou 1.250 µg F/mL, resultando em 6 grupos de tratamento: 4-h/0-F; 8-h/0-F; 4-h/275-F; 8-h/275-F; 4-h/1.250-F e 8-h/1.250-F. As concentrações de 275 e 1.250 µg F/mL simularam uma diluição salivar na cavidade bucal quando dentifrícios de 1100 e 5000 µg F/g são usados. A desmineralização do esmalte foi avaliada na superfície (%PDS) e dureza em corte. Fluoreto incorporado pelo esmalte também foi determinado. Os dados foram analisados por Análise de Variância e teste de Tukey. O tratamento com 1.250 µg F/mL reduziu significativamente %PDS comparado ao de 275 µg F/mL (p 〈 0,05), independente do nível do desafio cariogênico (comparações 4-h/1,250-F x 4-h/275-F e 8-h/1,250-F x 8-h/275-F, respectivamente). Esses resultados foram suportados pela concentração de fluoreto encontrada no esmalte. Os resultados sugerem que maior concentração de fluoreto pode parcialmente compensar um maior risco de cárie sob um maior desafio cariogênico provocado pelo aumento de exposição ao açúcar.

    Abstract: Abstract Introduction The absence of functional dentition compromises people´s quality of life, reflecting on their perceptions, including the self-perceived need for dental treatment in adults. However, this relation is not very clear in literature. Objective To evaluate if the absence of functional dentition is associated to the self-perceived need for dental treatment in adults. Method Analytical cross-sectional study was performed, in which data of the National Oral Health Survey conducted in 2010 was used. The age group evaluated was 35 to 44 years. After bivariate and multivariate analyzes, the association between the absence of functional dentition and other variables as the self-perceived need for dental treatment, sociodemographic conditions and health endpoints was verified. Results From the 9.564 adults, approximately 20% of the individuals did not show functional dentition. The absence of functional dentition was lower in adults who were aware of the self-perceived need for dental treatment (OR:0.55; IC95%:0.39-0.75). The female gender (OR:1.76; IC95%:1.39-2.22), older age (OR:2.53; IC95%:2.01-3.18) and lower schooling (OR:0.82; IC95%:0.79-0.85) were associated with the absence of functional dentition. Conclusion The absence of functional dentition is greater in adults who do not have self-perceived need for dental treatment.

    Abstract: To evaluate the influence of the thickness and type of computer‐aided design and computer‐aided manufacturing (CAD‐CAM) material on the fatigue resistance and failure mode of endodontically treated teeth (ETT) restored with occlusal veneers (OV). Materials and methods Seventy‐five (N = 75) ETT were restored with Herculite XRV in the endodontic access. Five experimental groups (n = 15) were tested. Four groups had two different thicknesses (0.6‐0.7 mm or 1.4‐1.6 mm) and two different CAD‐CAM materials: zirconia‐reinforced lithium‐silicate (LS/Celtra Duo) and composite resin (RC/Cerasmart). The fifth group (control) did not have occlusal veneers. All the specimens were subjected to accelerated fatigue (5 Hz frequency) with an occlusal load increasing up to 1800 N and 131,000 cycles. The number of cycles was recorded when the machine stopped or at the completion of the test. Fatigue resistance was analyzed using the Kaplan‐Meier survival test (95% significance level, log‐rank post hoc pairwise comparisons). The samples were categorized according to failure mode. The CAD‐CAM materials were examined through scanning electron microscopy (SEM) and energy dispersive X‐ray spectroscopy (EDS). Results No differences were found between the thicknesses, regardless of the type of the CAD‐CAM material. The thick LS OV outperformed the RC and control groups. The thin RC OV and control groups showed a higher percentage of repairable and possibly repairable failures than the other groups. LS was more homogeneous under SEM, and the EDS analysis detected Si and Zr, but not Li. Conclusions A larger thickness did not improve the resistance of the CAD‐CAM materials. Thick LS showed a higher cumulative survival rate to fatigue than the RC and control groups. The direct composite alone (control) survived similarly to the experimental groups, except for the thick LS.

    Abstract: To evaluate the effects of human saliva decontamination protocols on bond strength of resin cement to zirconia (Y‐PSZ), wettability, and microbial decontamination. Materials and methods Zirconia plates were sandblasted and divided into (a) not contaminated, (b) contaminated with human saliva and: (c) not cleaned, (d) cleaned with air‐water spray, (e) cleaned with 70% ethanol, (f) cleaned with Ivoclean, or (g) cleaned with nonthermal atmospheric plasma (NTAP). The wettability and microbial decontamination of the surfaces were determined after saliva contamination or cleaning. Monobond Plus (Ivoclar Vivadent) was applied after cleaning, followed by Variolink LC (Ivoclar Vivadent). The samples were stored 1 week before shear bond strength (SBS) testing, and data (SBS and wettability) were analyzed by one‐way analysis of variance and Tukey test ( α = .05). Results Saliva contamination reduced SBS to zirconia compared to not contaminated. Both Ivoclean and NTAP produced higher SBS compared to not cleaned and were not significantly different from the not contaminated. Ivoclean produced the highest contact angle, and NTAP the lowest. With the exception of using just water‐spray, all cleaning protocols decontaminated the specimens. Conclusions Both Ivoclean and NTAP overcame the effects of saliva contamination, producing an SBS to zirconia comparable to the positive control. Clinical significance Dental ceramics should be cleaned prior to resin cementation to eliminate the effects of human saliva contamination, and Ivoclean and NTAP are considered suitable materials for this purpose.
