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

Aim: This study aimed to evaluate the decision-making by patients to replace temporary restorations with permanent restorations after endodontic treatment and to verify the associated factors and evaluate the quality/integrity of the temporary restorative material within one month. Methods: This is a cross-sectional study using non-probabilistic sampling which analyzed patients after one month of endodontic treatment. The self-administered questionnaire contained sociodemographic, treatment decision-making and endodontic treatment questions. The restoration present in the mouth was evaluated in the clinical oral examination. The Poisson Regression test was used to verify the prevalence ratio. Results: The prevalence failure to perform permanent restorations was 61.1% of patients, and 42.7% reported not having adhered. The reasons are lack of time and not knowing the importance of replacing the restoration with a definitive one. The glass ionomer temporary restorative frequency was higher among those who chose not to replace the temporary restoration with a permanent one (PR=5.19; 95%CI 2.10-12.33). In addition, there was an association between the quality of the restorative material and the type of material, and the best clinical quality of the restoration was statistically associated with glass ionomer and composite resin. Conclusions: The findings show the importance of guidance by the dental surgeon in helping patients decide to replace their temporary restoration

ABSTRACT

Aim: A retrospective, cross-sectional study was carried out to evaluate the performance of resin composite restorations placed by undergraduate dental students with 1 to 15 years of placement based on dental records. Methods: Four calibrated operators evaluated 498 restorations (anterior and posterior) of 120 patients according to Ryge's validated criteria (USPHS). Results: The criteria that showed the smallest changes between the types of failures were color matching, marginal discoloration and surface texture. Regarding the longevity, the surface texture showed an increase in the frequency of failures from the second time interval (3.1 to 6 years). Higher prevalence of failure was found in class II and III restorations, with secondary caries being the main reason. No significant differences were found for anatomic form, marginal adaptation, and color matching. Class V restorations showed a higher fracture rate with total displacement of the restoration, with no increase in the frequency of fracture over time. Conclusion: High rate of restoration failure was observed, possibly due to the lack of experience and skills of the students. This outcome highlight the need for continuous revision and improvements of teaching practice regarding the development of clinical competences and skills by dental students

ABSTRACT

O presente trabalho tem como objetivo realizar uma revisão de literatura e discutir os mais atuais conceitos sobre abordagem conservadora de lesões cariosas profundas, facilitando o manejo clínico. Para que essa abordagem conservadora seja implementada, é imprescindível que se conheça a composição estrutural e funcional do biofilme para, assim, entender a evolução da doença cárie que acomete a estrutura dentária. No entanto, quando se trata de um dente com lesão de cárie ativa com grande comprometimento de esmalte e dentina, procedimentos operatórios mais invasivos e restauradores podem ser necessários, mesmo que fundamentados na maior preservação possível de estrutura dentária. As evidências mais atuais encontradas na literatura recomendam a remoção seletiva do tecido cariado que consiste na dentina infectada, ou seja, clinicamente amolecida, e restauração definitiva na mesma sessão. Portanto, desde que o dente apresente vitalidade pulpar clinicamente confirmada, acredita-se que a preservação estratégica da dentina, poderá aumentar as chances de sucesso no tratamento, evitando possível exposição da polpa dentária. Adicionalmente, ao optar por práticas conservadoras no contexto da Odontologia de mínima intervenção, resultará em um significativo aumento na longevidade das restaurações sempre associando promoção de saúde ao paciente(AU)


This paper aims to conduct a literature review and discuss the most current concepts on conservative approach to deep carious lesions in permanent posterior teeth, facilitating clinical management. For this conservative approach to be implemented, it is essential to know the structural and functional composition of the biofilm in order to understand the evolution of the caries disease that affects the dental structure. However, when it comes to a tooth with an active caries lesion with major enamel and dentin compromise, more invasive and restorative surgical procedures may be necessary, even if based on the greatest possible preservation of the dental structure. The most current findings in the literature recommend the selective removal of carious tissue consisting of infected dentin, that is, clinically softened, and definitive restoration in the same session. Therefore, as long as the tooth has clinically confirmed pulp vitality, it is believed that the strategic preservation of dentin may increase the chances of successful treatment, avoiding possible exposure of the dental pulp. Additionally, when opting for conservative practices in the context of Minimally Invasive Dentistry, it will result in a significant increase in the longevity of restorations, always associating health promotion to the patient(AU)

ABSTRACT

O objetivo deste relato de caso foi descrever em detalhes a técnica de transfixação de pino de fibra de vidro no sentido horizontal e restauração de resina composta em um dente molar tratado endodonticamete. Paciente, sexo feminino, 51 anos de idade, buscou o Centro Universitário da Serra Gaúcha (FSG ­ Caxias do Sul ­ Rio Grande do Sul) com a necessidade de realizar tratamento endodôntico do elemento molar número 26. Após a avaliação inicial, foi realizada a endodontia. O elemento havia pouca sustentação das paredes vestibular e palatina, então foi proposto a colocação de pino intrarradicular seguido de coroa, entretanto, por questões financeiras a paciente não aceitou. Logo, foi proposto a técnica de transfixação horizontal de pino de fibra de vidro associado a uma restauração de resina composta de forma direta. O procedimento foi realizado em sessão única e foi utilizado um pino de fibra de vidro número 1 disposto transversalmente entre as paredes mesiopalatina e distovestibular. A restauração foi realizada com resina composta Filtek Z350, devolvendo estética e função ao elemento dentário. Pode-se concluir que a técnica de transfixação horizontal de pino de fibra de vidro associado à resina composta é uma alternativa restauradora que possibilita maior resistência aos dentes tratados endodonticamente, apresenta resultados funcionais e estéticos satisfatórios, além de possibilitar uma maior sobrevida aos mesmos(AU)


The purpose of this case report was to describe in detail the technique of horizontal transfixion of a fiberglass post into an endodontically treated tooth. Female patient, 51 years old, sought the University Center of Serra Gaúcha (FSG - Caxias do Sul ­ Rio Grande do Sul) with the need to perform the endodontic treatment of molar element number 26. After the initial evaluation, endodontics was performed. The element had little support for the buccal and palatal walls, so an intraradicular postplacement followed by a crown was proposed, for financial reasons the patient did not accept it. Therefore, the technique of horizontal transfixion of a fiberglass pin was proposed, associated with a restoration of direct composite resin. The procedure was performed in a single session and a number 1 fiberglass post was fixed crosswise between the mesiopalatal and distobuccal walls. The restoration was carried out with composite resin Filtek Z350, restoring aesthetics and function. It can be concluded that the horizontal transfixion of a fiberglass post associated with composite resin technique is a restorative alternative that allows greater resistance to endodontically treated teeth, provides satisfactory esthetics and better survival rates(AU)

ABSTRACT

Para el adecuado ejercicio de la odontología, los procedimientos realizados deben ejecutarse apegándose en todo momento a las normas y principios éticos propios de la profesión. Cuando un odontólogo decide, por voluntad propia, ejercer la profesión sin apegarse a dichos principios, se considera que actúa con negligencia. La negligencia se caracteriza por ser un acto indebido, en el cual el profesional ejecuta por voluntad propia acciones injustificables capaces de producir daños en la salud de los pacientes o en el pronóstico de un tratamiento. Los actos negligentes, además de atentar contra la integridad del paciente, ponen en riesgo a los profesionales de la salud que los cometen de sufrir consecuencias legales derivadas de dichos actos. El objetivo del presente artículo consiste en definir el concepto de negligencia, describir las formas más comunes en las que ésta se comete durante la consulta odontológica así como sus posibles consecuencias legales, ilustrándolas a su vez con la breve presentación de algunos casos (AU)


For the proper practice of dentistry, the procedures performed must be carried out adhering at all times to the standards and ethical principles of the profession. When a dentist voluntarily decides to practice the profession without adhering to these principles, he is considered to be acting negligently. Negligence is characterized as an improper act, in which the professional voluntarily executes unjustifiable actions capable of causing damage to the health of patients or the prognosis of a treatment. Negligent acts, in addition to threatening the integrity of the patient, put health professionals at risk who commit legal consequences derived from these acts. The aim of this article is to define the concept of negligence, to describe the most common ways in which it is committed during the dental practice as well as its legal consequences, illustrating them in turn with a brief presentation of some cases (AU)

ABSTRACT

Los cambios en la vida, así como también en el campo de la Odontología, deben ser para mejorar siempre en todos los aspectos posibles. Y muchos de los cambios recientes en la Odontología Restauradora están encaminados a la utilización de materiales estéticos para remplazo de restauraciones metálicas previas, sin generar certeza total de ser mejores opciones. Esto ha generado un marcado incremento en la tendencia a practicar, más enfáticamente, el remplazo de restauraciones previas (AU)


Changes in life, as so in the field of Dentistry, should always be for the improvement on most possible aspects. Many of the recent changes in Restorative Dentistry are focus on the use of cosmetic materials to replace previous metallic restorations, without total certainty of being better options. This has generated a marked increase in the tendency to practice, more emphatically, the replacement of previous restorations (AU)

ABSTRACT

Na Odontologia, o tratamento adequado depende da condição clínica de cada paciente, do conhecimento do profissional e dos materiais empregados. As coroas com sistemas cerâmicos puros se apresentam como excelente alternativa restauradora, demonstrando potencial estético superior ao das coroas metalocerâmicas. Este presente estudo teve como objetivo, relatar um caso clínico onde se realizou uma reabilitação estética de dentes anteriores com coroas de cerâmica pura à base de dissilicato de lítio. O paciente apresentava falta de harmonia e estética entre os dentes anteriores 12,11,21 e 22, na qual foi planejado e executado a reabilitação com coroas E-max desses elementos, bem como a substituição das restaurações dos dentes inferiores anteriores, e também foi realizado a confecção de coroa E-max do dente 35. Concluímos que as reabilitações estéticas de dentes anteriores com coroas de sistemas cerâmicos puros à base de dissilicato de lítio se apresentam como uma excelente alternativa reabilitadora, na qual o tratamento multidisciplinar é um fator considerado essencial, possibilitando restabelecer a estética e a funcionalidade do sorriso do paciente, a fim de alcançar o êxito do tratamento reabilitador(AU)


In dentistry, the appropriate treatment depends on the clinical condition of each patient, the knowledge of the professional and the materials used. Crowns with pure ceramic systems are an excellent restorative alternative, demonstrating an aesthetic potential superior to that of metalloceramic crowns. This present study aimed to report a clinical case where an aesthetic rehabilitation of anterior teeth was performed with crowns of pure ceramic based on lithium disilicate. The patient had a lack of harmony and aesthetics between the anterior teeth 12,11,21 and 22, in which the rehabilitation with E-max crowns of these elements was planned and performed, as well as the replacement of the anterior lower teeth restorations, and was also made the E-max crown of tooth 35. We conclude that the aesthetic rehabilitation of anterior teeth with crowns of pure ceramic systems based on lithium disilicate is an excellent alternative for rehabilitation, in which multidisciplinary treatment is considered an essential factor, making it possible to restore the aesthetics and functionality of the patient's smile, in order to achieve the success of the rehabilitation treatment(AU)

ABSTRACT

Objetivo: Comparar clínicamente el comportamiento, el tiempo operatorio requerido, el costo y la dificultad de diferentes técnicas de restauración en piezas primarias, empleando ionómero vítreo fotoactivado (IVF) polvo/líquido, con y sin uso de acondicionamiento dentinario, y en cápsulas, con acondicionamiento. Materiales y métodos: El diseño de este estudio fue experimental y comparativo. Se realizaron, en 18 pacientes de 7±2 años, 33 restauraciones con IVF de una o más piezas primarias vitales con lesiones amelodentinarias en 1 o 2 superficies. Según su día de concurrencia a la Cátedra de Odontología Integral Niños, se empleó: A) IVF polvo/líquido, con acondicionamiento (3M™ VitremerTM); B) IVF polvo/líquido, sin acondicionamiento (3M™ VitremerTM); y C) IVF en cápsulas, con acondicionamiento (Riva Light Cure). Las restauraciones fueron evaluadas clínicamente al inicio y a los 12 meses según los siguientes criterios: pérdida total, pérdida total con caries, requerimiento de reemplazo por pérdida parcial, requerimiento de reemplazo por caries, aceptable con deterioro, en condiciones. El grado de dificultad se analizó utilizando una planilla diseñada para tal fin. El tiempo operatorio requerido se midió sin considerar el tiempo de inserción. Resultados: El tiempo operatorio requerido fue de 2 minutos, 15 segundos en A; 1 minuto, 25 segundos en B; y 1 minuto, 10 segundos en C, sin considerar el tiempo de inserción. El costo fue 61,11% mayor para C. La dificultad fue de 3,2±0,6 para A y B, y de 1,5±0,7 para C (ANOVA; P<0,001). El comportamiento clínico no registró diferencias significativas entre los grupos (Fisher; P=0,339). Conclusión: Los ionómeros de restauración fotoactivados encapsulados utilizados en este estudio presentaron menor dificultad de manipulación, mayor costo y similar comportamiento clínico a un año que las presentaciones polvo-líquido, con o sin uso de acondicionamiento previo en piezas primarias (AU)


Aim: To assess the clinical performance, operative time required, cost and technical difficulties of different restorative techniques in primary teeth, using light cured glass ionomers (LCG), powder/liquid, with and without dentin conditioning and light cured glass ionomer in capsules with conditioning. Materials and methods: The design of this study was experimental and comparative. 33 restorations with LCG were performed in 18 patients, 7 ± 2-years-old, in one or more vital primary teeth with carious lesions involving one or more tooth surfaces. Patients were assigned to one of the three groups according to the day of the week in which they attended to the Pediatric Department of the Dental School: A) LCG powder/liquid, with conditioning (3M™ VitremerTM); B) LCG powder/liquid without conditioning (3M™ VitremerTM); and C) LCG in capsules with conditioning (Riva Light Cure). The restorations were clinically evaluated at baseline and after 12 months according to the following criteria: complete loss of the restoration, complete loss with caries, need of replacement because of partial loss, need of replacement because of caries, good condition with some wear and good condition. Technical difficulties were analyzed using a data sheet designed for that purpose. The operative time required was evaluated without considering the insertion time. Results: Time operative time required was 2 minutes 15 seconds in A, 1 minute 25 seconds in B and 1 minute 10 seconds in C. Cost was 61.11% higher for C. Difficulty was 3.2±0.6 for A and B and 1.5±0.7 for C (ANOVA; P<0.001). No significant differences were observed among the three groups in relation to the clinical performance (Fisher; P=0.339). Conclusions: In these 12 months, study in primary teeth, the light cured glass ionomers used dispensed in capsules showed to be the easiest to handle, had higher cost and similar clinical performance than the powder liquid presentations with and without dentin conditioner (AU)

ABSTRACT

La restauración ideal en los dientes tratados endodónticamente (DTE) ha sido un tema controversial y ampliamente discutido en la literatura odontológica. El alto índice de fracasos en los dientes endodónticos se asocia principalmente a la falta de un adecuado sellado coronario, motivo por el cual la restauración post endodóntica cumple un papel fundamental. Los propios tejidos del DTE constituyen el refuerzo más importante de la pieza dentaria. La odontología considerada hoy en día como ideal es la mínimamente invasiva. A su vez la restauración de elección deberá ser aquella que respete mayor cantidad de tejido remanente a la hora de seleccionar la restauración coronaria. Se deberá considerar la cantidad y la calidad del remanente dentario sano, como los requisitos funcionales de cada pieza en particular. Si bien existen diversos tipos de restauraciones que podrían rehabilitar un DTE, en este trabajo sólo nos referiremos a las de inserción rígida, específicamente a las endo-onlays, también denominadas endocrowns (AU)

ABSTRACT

Al momento de realizar una preparación dental existen diferentes alternativas. Dentro del instrumental rotatorio hay dos opciones: la turbina dental (ultra-velocidad) y el micromotor acoplado a un contra-ángulo multiplicador (alta velocidad). El propósito de este estudio fue evaluar cualitativamente la diferencia en la lisura superficial sobre esmalte, que se genera al desgastarlo, utilizando para esto, una turbina dental y un micromotor eléctrico acoplado a un contra-ángulo multiplicador 1:5 (anillo rojo). Se realizó un análisis cualitativo sobre una muestra de 24 superficies de esmalte obtenidas de 12 premolares extraídos por indicación ortodóntica, los cuales fueron preparados y observados al microscopio óptico. Luego de observar las 24 superficies al microscopio se pudo constatar una mayor lisura superficial sobre el esmalte al utilizar micromotor eléctrico acoplado a contraángulo multiplicador en comparación con turbina (AU)

ABSTRACT

El objetivo de este artículo es presentar una alternativa de tratamiento rehabilitador para pacientes jóvenes con gran pérdida de estructura dental vinculada a lesiones de origen no bacteriano. Se presenta el caso clínico de un paciente de 36 años de edad, con reflujo gastroesofágico crónico bajo tratamiento médico, que concurrió a la Cátedra de Odontología Integral Adultos de la Facultad de Odontología de la Universidad de Buenos Aires (FOUBA), en busca de un cambio estético en su sonrisa y relatando sensibilidad al calor, al frío y dolor al masticar. No manifestó sintomatología dolorosa a nivel muscular ni articular. En función de sus posibilidades económicas y de la etiología erosiva de las lesiones existentes en sus piezas dentarias, se llevó a cabo una rehabilitación oral adhesiva con resinas compuestas utilizando la sistematización de atención que sugiere la Cátedra. Las resinas compuestas actuales, en combinación con las técnicas y procedimientos desarrollados en este artículo han demostrado un adecuado comportamiento al ser utilizadas como restauraciones definitivas en pacientes que necesitan rehabilitación oral total debido a la gran pérdida de estructura dental por erosión ácida (AU)

ABSTRACT

Abstract Caries management at the lesion level is dependent on the lesion activity, the presence of a cavitation (either cleanable or non-cleanable), and lesion depth as evaluated via radiographic examination. A variety of non-invasive, micro-invasive, and minimally invasive treatment (with or without restoration) options are available for primary and permanent teeth. Non-invasive strategies include oral hygiene instructions, dietary counseling, and personal as well as professional use of fluoridated products that reduce demineralization and increase re-mineralization. Micro-invasive procedures include the use of occlusal resin sealants and resin infiltrants, while minimally invasive strategies comprise those related to selective removal of caries tissues and placement of restorations. Deep caries management includes indirect pulp capping, while exposed pulp may be treated using direct pulp capping and partial or complete pulpotomy. The aim of the present study was to review available evidence on recommended preventive and restorative strategies for caries lesions in Latin American/Caribbean countries, and subsequently develop evidence-based recommendations for treatment options that take into consideration material availability, emphasize ways to adapt available treatments to the local context, and suggest ways in which dentists and health systems can adopt these treatments.

ABSTRACT

Abstract Objective To compare the effectiveness of ART restorations using High Viscosity Glass-ionomer cement (HVGIC) with conventional restorations using resin composite in Class II cavities of permanent teeth, in a 2-year follow-up. Methodology Seventy-seven restorations were made with each restorative material, Equia Fil-GC Corporation (ART restorations) and Z350-3M (conventional restoration), in 54 participants in this parallel and randomized clinical trial. Restorations were evaluated at 6 months, 1 and 2 years using the ART and the modified United States Public Health Service (USPHS) criteria. Chi-square test and Survival Analysis (p<0.05) were used for statistical analysis. Results The success rates for ART restorations were 98.7% (6 months) and 95.8% (1 year) for both criteria. At 2 years, success rate was 92% and 90.3% when scored by the modified USPHS and ART criteria (p=0.466), respectively. The success rates for conventional restorations were 100% (6 months), 98.7% (1 year) and 91.5% (2 years) for both assessment criteria. ART restorations presented a lower survival rate by the criterion of ART (83.7%) when compared to the modified USPHS criterion of (87.8%), after 2 years (p=0.051). The survival of conventional restorations was 90.7% for both evaluation criteria. Conclusion At the 2-years follow-up evaluation, no statistically significant difference was observed between the success rate of ART restorations with HVGIC compared to conventional restorations with resin composite in Class II cavities of permanent teeth.

ABSTRACT

A pesar de los avances e innovaciones de los materiales dentales, la microfiltración marginal y la contracción durante la polimerización continúan siendo una de las causas principales del fracaso de los tratamientos en odontología restauradora. Un sellado marginal correcto será posible cuando las fuerzas de adhesión superen las fuerzas generadas por la contracción de polimerización y las fuerzas generadas por los cambios dimensionales térmicos posteriores a la polimerización, por lo que investigaciones previas demostraron que estas limitaciones pueden ser superadas con el uso de resinas Bulk Fill como material de relleno de cavidades extensas y profundas de dientes posteriores. Estas resinas. de relleno masivo, están recibiendo atención, principalmente porque se pueden colocar, a diferencia de las resinas convencionales, en incrementos de 4 mm sin afectar la contracción de la polimerización, la adaptación de la cavidad o el grado de conversión. El objetivo de la presente revisión bibliográfica es describir la contracción de polimerización y la consecuente filtración marginal que sufren las resinas compuestas para el sector posterior Bulk Fill con base de datos de la literatura (AU)


Despite advances and innovations in dental materials, marginal microfiltration and shrinkage during polymerization continue to be one of the main causes of treatment failure in Restorative Dentistry. A correct marginal seal will be possible when the adhesion forces exceed the forces generated by polymerization contraction and the forces generated by post-polymerization thermal dimensional changes, for which previous research has shown that these limitations can be overcome with the use of Bulk Fill resins as filling material for large and deep posterior tooth cavities, these massive filling resins are receiving attention mainly because they can be placed, unlike conventional resins, in 4 mm increments without affecting polymerization shrinkage. , cavity adaptation or degree of conversion. The objective of the present bibliographic review is to describe the polymerization contraction and consequent marginal filtration suffered by Composite Resins for the Bulk Fill posterior sector with a literature database (AU)

ABSTRACT

Objetivo: Este ensaio clínico randomizado avaliou o comportamento de restaurações com resina composta bulk-fill flow em dentes posteriores após três anos do tratamento restaurador. Métodos: Dezessete pacientes (12 mulheres, 5 homens, idade 23-59) foram selecionados para ter pelo menos duas restaurações de amálgama ou de resina composta substituídas, ou receber tratamento restaurador para lesão cariosa. As cavidades foram aleatoriamente alocadas para receberem o compósito bulk-fill flow Suferil SDR Flow, oclusamente coberto por uma resina composta convencional nano-híbrida Esthet-X HD (técnica bulk and body), ou serem preenchidas exclusivamente com Esthet-X HD, inseridas em incrementos de 2mm cada técnica incremental). Um adesivo convencional de dois passos foi aplicado em todas as cavidades. Trinta e quatro restaurações Classes I ou II foram realizados em dentes posteriores (n=17) no início do estudo (baseline). Após 03 anos, os critérios do USPHS modificado e FDI foram utilizados para avaliar as restaurações. Os dados foram submetidos à análise estatística Mann-Whitney (p<0,05). Resultados: No acompanhamento de 3 anos, vinte e quatro restaurações (17 Classes I e 7 Classes II) foram avaliadas. Não foram detectadas diferenças entre as técnicas restauradoras (p>0,05). Não houve falha em nenhuma restauração ao longo do tempo. Conclusão: Após 03 anos de serviço clínico, todas restaurações utilizando um compósito bulk-fill flow em dentes posteriores demonstraram uma performance satisfatória. Significância Clínica: A qualidade geral das restaurações em dentes posteriores realizadas com a técnica bulk and body foi similar ao das restaurações incrementais utilizando um compósito nano-híbrido.

Objective: This randomized clinical trial evaluated the behavior of restorations with flowable bulk-fill resin composite in posterior teeth three years after the restorative treatment. Methods: Seventeen patients (12 women, 5 men, age 23-59) were selected to have at least two failing amalgam or resin restorations replaced and/or to have a carious lesion restored. The cavities were randomly allocated to receive either the flowable bulk-fill composite Surefil SDR Flow occlusally covered with the conventional nano-hybrid composite Esthet-X HD (bulk and body technique) or filled exclusively with Esthet-X HD placed in 2 mm increments (incremental technique). A two-step etch-and-rinse adhesive was applied in all cavities. Thirty-four Class I or II restorations were performed in posterior teeth (n=17) during baseline. After 03 years, modified USPHS and FDI criteria were used to evaluate the restorations. Data were subjected to Mann-Whitney statistical analysis (p<0.05). Results: At the 3-year follow-up, twenty-four restorations (17 Class I and 7 Class II) were evaluated. No diff erences were detected between the bulk and body and the incremental restorations (p>0.05). No restoration failures were observed over time. Conclusion: After 03 years of clinical service, all restorations using a flowable bulk-fill composite in posterior teeth showed an acceptable performance. Clinical Significance: The overall quality of posterior restorations made with the bulk and body technique was similar to that of restorations made with a nano-hybrid composite incrementally placed.

ABSTRACT

Purpose: Two important factors in dental prosthesis are making an accurate impression and producing a suitable cast which represents the exact relationship between prepared tooth and oral structures. This study, aimed to investigate the effects of different combinations of impression and pouring materials on marginal and internal adaptation of premolar zirconia crowns. Material and Methods: Forty maxillary premolars were prepared considering round shoulder finish line. The impressions were made either by additional (Panasil) or condensation (Speedex) silicon, and poured by two different types of gypsum materials (Siladent or GC gypsum) (N=10). Zirconia crowns were fabricated using a CAD-CAM system. The crowns were cemented, and the samples were cut in bucco-lingual direction. Marginal and internal gaps were measured by stereomicroscope (×25). Results: The mean marginal gaps for Pansil-Siladent, Panasil-GC, Speedex-Siladent, and Speedex-GC were 141 µm, 143 µm, 131 µm, and 137 µm respectively. The internal gaps were 334 µm, 292 µm, 278 µm, and 257 µm respectively. The independent T-Student test showed no significant differences in average marginal or internal gap among various impression and gypsum materials or their interactions (p>0.05). Two-way ANOVA test showed no significant differences in maximum marginal or internal gap among various impression and gypsum materials and their interactions (p>0.05). Conclusion: The present study revealed no statistically significant difference in marginal/internal gap among crowns prepared using different combinations of impression-pouring materials evaluated.


Introducción: Dos factores importantes en la prótesis dental son hacer una impresión precisa y la producción de un modelo adecuado que represente la relación exacta entre el diente preparado y las estructuras orales. Este estudio, tuvo como objetivo investigar los efectos de diferentes combinaciones de materiales de impresión y vertido sobre la adaptación marginal e interna de coronas de zirconio premolar. Material y Métodos: Se prepararon cuarenta premolares maxilares considerando la línea de meta del hombro redondo. Las impresiones se realizaron con silicio adicional (Panasil) o de condensación (Speedex) y se vertieron con dos tipos diferentes de materiales de yeso (yeso Siladent o GC) (N = 10). Las coronas de zirconio se fabricaron utilizando el sistema CAD-CAM. Las coronas se cementaron y las muestras se cortaron en dirección buco-lingual. La brecha marginal e interna se midió con estereomicroscopio (×25). Resultados: Las brechas marginales medias para Pansil-Siladent, Panasil-GC, Speedex-Siladent y Speedex-GC fueron de 141µm, 143µm, 131µm y 137µm, respectivamente. Las brechas internas fueron 334µm, 292µm, 278µm y 257µm, respectivamente. La prueba de T-Student independiente no mostró diferencias significativas en la brecha marginal o interna promedio entre varios materiales de impresión y yeso o sus interacciones (p>0.05). La prueba ANOVA bidireccional no mostró diferencias significativas en el espacio marginal o interno máximo entre varios materiales de yeso y de impresión y sus interacciones (p>0.05). Conclusión: El presente estudio no reveló diferencias estadísticamente significativas en la brecha marginal/interna entre las coronas preparadas con diferentes combinaciones de materiales de impresión y vertido evaluados.

ABSTRACT

Abstract The aim was to evaluate the microtensile bond strength (mTBS) to dentin and interfacial stress in a class II cavity restored with bulk-fill or conventional composite resins and the margin interfaces. Vertical slot class II cavities in the mesial face, with the gingival end in dentin, were prepared in 72 third molars, being divided into groups (n=24): G1-Tetric N-Ceram; G2-Tetric N-Ceram Bulk-Fill; G3-SonicFill. Clearfil SE Bond adhesive system was used in all groups. Half of the teeth in each group (n=12) were submitted to thermo-mechanical cycling (TMC). Restored teeth (n=9) were cut perpendicular to obtain beams, which were submitted to a mTBS test in an EMIC machine. The cervical margins in dentin of the restored teeth (n=3) were assessed using SEM through epoxy resin replicas as well as the section of the restoration. Interfacial stresses after load application were calculated by 2D finite element analysis. The mTBS means-MPa followed by different letters represent statistical difference by ANOVA and Games-Howell's test (p<0.05): Without TMC: G1-15.68±6.10a; G2-10.08±5.21ab; G3-7.98±3.76b. With TMC: G1-9.70±5.52a; G2-5.79±1.42a; G3-4.37±1.87a. Interfacial stress (MPa) was 4.4 for SonicFill, 3.9 for Tetric N-Ceram, and 3.5 for Tetric N-Ceram Bulk-Fill. SEM images showed continuous margins for all composite resin restorations. It was possible to conclude that SonicFill obtained a slightly higher interfacial stress and lower bond strength to dentin in comparison with Tetric N-Ceram and Tetric N-Ceram Bulk-Fill. Continuous margin interfaces were obtained for Tetric N-Ceram, Tetric N-Ceram Bulk-Fill, and SonicFill. However, voids were observed in the SonicFill restorations.


Resumo O objetivo foi avaliar a resistência de união à microtração (RUμT) à dentina e o estresse interfacial em cavidades classe II restauradas com resina composta de incremento único ou convencional e as interfaces marginais. Cavidades classe II na face mesial, com margem gengival em dentina, foram confeccionadas em 72 terceiros molares, sendo divididos em grupos (n=24): Grupo 1-Tetric N-Ceram; Grupo 2- Tetric N-Ceram Bulk-Fill; Grupo 3- SonicFill. O Sistema adesivo Clearfil SE Bond foi usado em todos os grupos. Metade dos dentes de cada grupo (n=12) foram submetidos à ciclagem termo-mecânica (CTM). Os dentes restaurados (n=9) foram cortados perpendicularmente para obter palitos que foram submetidos ao teste de RµT na máquina-EMIC. As margens cervicais em dentina dos dentes restaurados (n=3) foram observados em microscopia eletrônica de varredura (MEV) por meio de réplicas em resina epoxy, assim como os cortes das restaurações. O estresse interfacial após a aplicação da carga foram calculadas por análise de elementos finitos 2D. As médias de RUμT-MPa seguidas de letras distintas apresentam diferença estatística de acordo com ANOVA e teste de Games-Howell (p<0,05): Antes da CTM: G1-15.68±6.10a; G2-10.08±5.21ab; G3-7.98±3.76b. Após CTM: G1-9.70±5.52a; G2-5.79±1.42a; G3-4.37±1.87a. O estresse interfacial (MPa) foi 4,4 para SonicFill, 3,9 para Tetric N-Ceram e 3,5 para Tetric N-Ceram Bulk-Fill. Imagens em MEV mostraram margens contínuas para todas as restaurações em resina composta. Foi possível concluir que o SonicFill obteve um estresse interfacial ligeiramente mais alto e menor resistência de união à dentina em comparação com o Tetric N-Ceram e o Tetric N-Ceram Bulk-Fill. Interfaces de margem contínua foram obtidas para Tetric N-Ceram, Tetric N-Ceram Bulk-Fill e SonicFill. Entretanto, espaços vazios foram observados nas restaurações do SonicFill.
