“…This study, while still correlating with those researching the effects of microleakage is very novel in its purpose not only to analyze the adhesive or bonding strength in vitro, as was the original goal of other researchers and/or manufacturers of such materials, but also to study the microleakage of the adhesive materials, which is one of the less-trialed factors, directly concerning long-term reliability, often leading to multiple dental diseases [14]. It is important to note that other dye-leakage studies have mostly evaluated the leakage level by degrees only [15][16][17][18], while Phanombualert et al [19] also offered measurements in micrometers. This study combines both.…”

Introduction: There are several methods of reducing a microleakage, and one of them is choosing appropriate adhesive material. The aim of the work was the in vitro analysis of 4 bonds: 3M ESPE “Single bond”, Dentsply “Prime and Bond Active”, Coltene “One Coat 7 Universal”, and Kuraray “Clearfil Universal Bond Quick”. Material and methods: 136 healthy molar teeth were collected and randomly split into 4 groups and Vth Class cavities were prepared. Chosen adhesives were used in four groups of teeth with the same composite. Teeth were the thermocycled, sealed, covered with lacquer, and submerged in 1% methylene blue solution for 24 h. After the thermocycling, the vertices of each tooth were sealed using dental wax. Each tooth was then fully covered with lacquer. All teeth were then submerged into 1% methylene blue solution for 24 h in room temperature. In the next step they were transversely cut through a center of restoration. The Olympus BX43 microscope was used to photograph each cut tooth. With the usage of Olympus stream software, measurement of the dye’s leakage was performed. Results. The statistical analysis proved that the most effective material when applied to ideally prepared cavity surface was Dentsply “Prime and Bond Active”. The second material was 3M ESPE “Single Bond”, third—Coltene “One Coat 7 Universal” and fourth—Kuraray “Clearfil Universal Bond Quick”. The most effective material applied to a too-dry surface was Dentsply “Prime and Bond Active”, second—3M ESPE “Single Bond”, third—Coltene “One Coat 7 Universal” and fourth—Kuraray “Clearfil Universal Bond Quick”. When it comes to too damp surfaces the best results were obtained with Dentsply “Prime and Bond Active” then Coltene “One Coat 7 Universal”, 3M ESPE “Single Bond” and Kuraray “Clearfil Universal Bond Quick”. Conclusion: The level of cavity dampness influences the quality of adhesives. Better results are obtained with over-dried surfaces than over-damp, which is connected with the dilution of the material.

“…It is then converted into heat that results in melting or burning, and vaporization of the affected area in the dentin. Melting and recrystallization of dentin results in obstruction of dentinal tubules and dentin hypersensitivity may be relieved (Mozaffari et al, 2016). It was reported that the highest bond strength results during the microtensile evaluation were found in laser followed by acid phosphoric usage.…”

Objective: Effective bond strength of composite resin restoration leads to its durability, so evaluation of dentin surface treatment with enzymes and laser for higher bond strength is an important factor.Materials and Methods: Sixty human molar teeth were cut at a depth of 2 mm of occlusal part and divided into six groups (n = 10). G1: etched with 37% phosphoric, G2 and G3: 10% papain or bromelain enzymes were used on the dentinal surface, G4: 10% papain and bromelain enzyme mixture were used for. Then, the specimens were washed with distilled water. In G5 and G6: Er:YAG or Co2 lasers were used on the dentin surface. An adhesive system was applied and then nanohybrid composite was placed in teflon mold and light cured. Samples were subjected to a shear bond strength (SBS) test by universal testing machines. Statistical analysis was performed, using one-way analysis of variance and Tukey HSD tests (p < .05). Results:The mean SBS in G1 was significantly higher in comparison with the other groups (p < .0001). On the other hand, a comparison of mean SBS between groups 2, 3, 4, and 5 shows no significant differences (p = .221). The mean SBS in group 6 (Co2 laser) was significantly lower in comparison with the other groups (p < .0001). Conclusion:Results showed that SBS of composite resin to dentin was not significantly affected, using either bromelain or papain 10% enzymes or erbium laser. Co2 laser had a negative effect on dentin and decreased the SBS. Phosphoric acid has the best result.

No se han establecido estándares para el tratamiento de cavidades cervicales no cariosas; un biomaterial adecuado permitirá buena adaptación y longevidad de la restauración. Objetivo: Determinar la microfiltración en cavidades clase V no cariosas restauradas con ionómero de vidrio y resina nanoparticulada. Materiales y métodos: Cavidades clase V realizadas en la superficie vestibular de 80 premolares sanos (1,5 mm de profundidad x 3 mm de altura en sentido ocluso-gingival x 2 mm de ancho en sentido mesio-distal) se restauraron aleatoriamente con dos biomateriales (n = 40): 1) ionómero de vidrio y 2) resina de nano relleno. Después, los especímenes fueron aislados con barniz y sumergidos en azul de metileno por 24 horas. Posteriormente, las muestras se sometieron 500 ciclos de termociclado por 8 horas y 45 minutos con cambios térmicos de 37°, 72° y 75°C, cada ciclo con una duración de 17 segundos. Las muestras fueron lavadas con agua destilada y seccionadas longitudinalmente para determinar el grado de microfiltración utilizando un estereoscopio (Leica M60, Biosystems). Los datos categóricos se analizaron con el test Chi2 en SPSS 24®. Resultados: Se pudo apreciar que la filtración es significativamente menor en resina que con ionómeros de vidrio (p < 0,001). Sin embargo, ninguno de los materiales de restauración probados fue capaz de sellar los márgenes o las paredes de los dientes completamente. Conclusión: Como resultado del presente experimento se determina que las restauraciones de clase V obturadas con resina de nano relleno presentan menor microfiltración marginal que las restauradas con ionómero de vidrio. Palabras clave: Filtración dental, adaptación marginal dental, resinas compuestas, cemento de ionómero vítreo, recubrimiento de la cavidad dental.
