“…Some studies have demonstrated that the sonic application of adhesive materials may be an excellent alternative for improving the interaction of these materials with the mineral structure of dentin [11,13,14,23,24]. The present study demonstrated that the use of the ultrasonic technique improved the performance of the self-adhesive resin cements RelyX U200 and Bifix SE.…”

“…An oscillating wave across the cement increases the fluidity, leading to a reduction in viscosity and consequently providing a greater power of diffusion [25]. Recently, one study showed that sonic devices resulted in films with fewer defects and that the use of sonic vibrations during the post accommodation process enhanced the cement flow [23]. Most authors investigating the effect of sonically applied dental material used ultrasonic devices.…”

The aim of this study was to evaluate the influence of a sonic application of self-adhesive resin cements on the bond strength of glass fiber posts to root dentin. Eighty bovine incisors were randomly divided into eight groups (n = 10). Four self-adhesive resin cements were used—RelyX U200 (3M/ESPE), Bifix SE (Voco), seT PP (SDI), and Panavia SA (Kuraray). The cements were inserted into the root canal in two different modes—Centrix syringe (control) or with a sonic device (Sonic Smart). The roots were sectioned and taken to a universal test machine (Instron 3342) to perform the push-out test. The fracture pattern was evaluated by stereomicroscope and scanning electron microscope. The bond strength data were analyzed by two-way ANOVA and Tukey tests (α = 0.05). The interaction between the main factors was significant (p = 0.002). The sonic application increased the bond strength in comparison with the conventional application for the RelyX U200 (p < 0.001) and Bifix SE (p < 0.017) cements. However, for the seT PP and Panavia SA cements, the bond strength values did not differ significantly (p > 0.05). The fracture pattern showed adhesive at the interface between the luting cement and the dentin. Using a sonic device in the application of self-adhesive resin cement helpedpromote an increase in the bond strength for RelyX U200 and Bifix SE.

“…The use of sonic vibration has also been proposed to improve the bond of the resin cement to fiberglass posts, favoring the flow of the cement and post accommodation. 6 Studies have suggested that sonic application of etch-and-rinse adhesives can increase the bond strength to coronal dentin because sonic devices sónica durante la acomodación posterior y las condiciones de envejecimiento (24 horas agua destilada o 5.000 ciclos térmicos). Los postes de fibra de vidrio (White Post DC1, FGM) se limpiaron con alcohol, se trataron con silano y se cementaron con cemento de curado dual (Allcem Core, FGM) o con cemento de resina autoadhesivo (seT, SDI).…”

“…Few studies reported the effect of sonic application directly on the post to improve the bond strength when compared with manual accommodation. 6,13 It has been reported that a sonic device for accommodating posts during the luting procedure resulted in more homogeneous films, with less defects and bubbles. 6 The Smart Sonic Device is a vibrating sonic energygenerating device that would be able to improve the diffusion and accommodation of different dental materials used in direct and indirect restorations.…”

Introduction: This study evaluated the influence of sonic vibration and thermocycling on the bond strength of fiberglass posts using conventional dual-cured and self-adhesive resin cements. Material and Methods: Ninety-six single-rooted endodontically treated teeth were divided randomly into eight groups according to the cement used (dual-cured or self-adhesive resin cement), use of sonic vibration during post accommodation, and aging conditions (24h in distilled water or 5,000 thermal cycles). The fiberglass posts (White Post DC1, FGM) were cleaned with alcohol, treated with silane and cemented with dual-cured (Allcem Core, FGM) or with self-adhesive resin cement (seT, SDI). For groups in which sonic vibration was used, the posts were accommodated, and sonic vibration was applied for 10 s using a special tip placed on top of the post (Sonic Smart Device, FGM). Pull-out tests were performed after storage in distilled water for 24h at 37°C or after thermocycling (5000 cycles, at 5°C and 55°C). The results were evaluated using three-way ANOVA and Tukey’s test (α=0.05). Results: Significant differences were not observed between the bond strengths of dual-cured (87.93±41.81 N) and self-adhesive cement (82.53±41.43 N). Bond strength for the sonic vibration groups (100.36±42.35 N) was significantly higher than for groups without sonic vibration (70.13±34.90 N). There were significant differences between specimens subjected to thermocycling (98.33±39.42 N) and those stored for 24h in distilled water (72.16±39.67 N). Conclusion: It can be concluded that both sonic vibration and thermocycling significantly improved bond strength of fiberglass posts with the two evaluated resin cements.

“…A pesar de que estos tres cementos son duales se requieren de una luz de fotocurado para completar su polimerización. El cemento adhesivo será fotocurado a una profundidad de 2mm con una lámpara LED y polimerizado de forma química en una profundidad mayor a 2 mm (28)(29)(30) .…”

A nuestros padres por su gran apoyo incondicional. A nuestra asesora de tesis la Dra. Leslie Casas por su comprensión, paciencia y apoyo. III RESUMEN Objetivo: El presente estudio in vitro compara la resistencia al cizallamiento de los cementos resinosos RelyX U200 (3M ESPE), MultilinkAutomix (IvoclarVivadent) y Allcem dual (FGM) en la interfase cerómero/dentina erosionada con la bebida carbonatada Coca Cola ®. Materiales y métodos: El diseño del estudio fue de tipo experimental in vitro. El tamaño muestral fue de 66 dientes bovinos, los cuales fueron seleccionados y cortados. Se expuso la dentina con lijas de diferentes granos y se confeccionó las bases de acrílico transparente. Se distribuyó en 3 grupos (n=22): RelyX U200 (3M ESPE), MultilinkAutomix (Ivoclar Vivadent) y Allcem dual (FGM). Se confeccionó cilindros de cerómero (4mm de diámetro y 6mm de altura) SR NEXCO (Ivoclar Vivadent), seguidamente fueron arenados. El desafío erosivo consistió en sumergir los especímenes en la bebida carbonatada Coca Cola ® durante tres ciclos de inmersión de 5 minutos al día durante5 días. La cementación de los bloques de cerómero a la dentina erosionada se realizaron según la indicación de cada fabricante. Las muestras se almacenaron en una estufa a 37°Ccon suero fisiológico al 0.09% por 24 horas. El análisis de los valores de cizallamiento se realizó con la máquina de ensayo universal (Instrom ®) en MPa (a una velocidad de 5mm/1min).Los resultados (media, desviación estándar) fueron realizados mediante estadística descriptiva y la comparación de la resistencia al cizallamiento fue analizada con la prueba Kruskal-Wallis seguida por una prueba de post-hoc con ayuda del comando Kruskal Wallis 2 en Stata ®. Resultados: Las medias y desviación estándar encontradas fueron cemento MultilinkAutomix (2,7±0,59), cemento RelyX U200(1,41±0,26) y el cemento Allcem dual (0,92±1,17). Se encontraron diferencias estadísticamente significativas (p=0.0001) al comparar la resistencia adhesiva de los tres cementos resinosos. En la prueba de post hoc de los tres cementos resinosos se encontraron que las tres diferencias son estadísticamente significativas (p
