“…The coloring method used to generate images and identify the fracture patterns herein was recently published. 13 The contrast of the stained areas makes it possible to identify the different interface components (bonding agent, composite and dental structure) present on the fractured area. The observed mixed fractured pattern occurred more frequently within the adhesive interface, and sometimes involved the restorative material ( Fig.…”

“…The fractured specimens were washed with distilled water and immersed in a solution of 4% methylene blue for 10 minutes to improve visualization with a Leica stereomicroscope (Leica Microsystems GmbH, Wetzlar, Germany) at 35× magnification. 13 The obtained images were examined using software (Leica Microsystems GmbH, Wetzlar, Germany) and the fracture pattern classified as adhesive, cohesive (in enamel or composite) or mixed.…”

Aims:To assess the influence of different bleaching protocols on the bond strength to enamel. Materials and methods:In this laboratory experiment were used forty sound bovine incisors were divided into five groups. G1: No bleaching (control). G2: 14 days bleaching with 4% hydrogen peroxide containing calcium (4% HP+Ca 2+ ) (2 hours/ day) and 24 hours of artificial saliva (AS) storage. G3: 14 days bleaching with 4% HP+Ca 2+ (2 hours/day) and 7 days storage in AS. G4: 28 days bleaching with 4% HP+Ca 2+ (2 hours/day) and 24 hours storage in AS. G5: 28 days bleaching with 4% HP+Ca 2+ (2 hours/day) and 7 days storage in AS. Following storage times, composite resin cylinders were built upon the enamel surfaces and tested for micros hearing. For statistical analysis, two-way ANOVA and Tukey's test was applied to the data (p ≤0.05), for it was evaluated different times of bleaching and stored in artificial saliva. Results:The highest mean was observed in G1 (14.61 MPa), and the lowest in G4 (9.22 MPa). Compared to the negative control (G1), no differences were found in 14 days bleaching and the same between G2 and G3 (p ≥0.01). However, in 28 days bleaching, the effects of the storage periods (24 hours and 7 days) were significantly different (p ≤0.05), besides G4 and G5 were statistically different from G1. Conclusions:Extended bleaching time (28 days) decreased the bond strength, independently of storage time in AS.Clinical significance: If adhesive procedures are required after extended at-home bleaching they may need to be delayed for at least for 7 days for the enamel adhesion ability to recover.

“…The method used in this study to capture the images of the predominant adhesive fracture pattern was previously used to describe the internal anatomy of deciduous swine teeth 6. It has become possible to identify different components (bonding agent, composite, and dental structure) in the area of the fracture using this type of microscopy by observing the contrast obtained through the use of pigment agents on the enamel surface.…”

“…The use of animal teeth in dental studies has become increasingly necessary due to the difficulty in collecting the required numbers of sound teeth in specific age ranges and tooth types. The animal processing industry may provide standardized biological materials on a large scale and in adequate quantities for research projects 6. Bovine, swine, and sheep teeth are among the animal teeth mostly used in dental research 7,8…”

Aim The aim of this study was to compare the bonding strength of dental materials in buffalo ( Bubalus bubalis var. kerebau ), bovine, and human enamel and the susceptibility of these substrates in acid etching. Materials and methods A total of 20 human third molars, 20 bovine incisors, and 20 buffalo incisors were used in a mechanical assay of microshear. The substrates were demineralized via conditioning with 37% phosphoric acid, and the ultra-morphological pattern of each substrate was analyzed by scanning electron microscopy. Results The results showed that there was no significant difference in adhesive bonding strength values between buffalo and human enamel ( P ≥0.05), with a fracture pattern of mixed type for all experimental groups. Conclusion The results indicate that buffalo enamel is similar to human dental substrate in tests of adhesive bonding strength and also show a similar behavior in the acid conditioning of the enamel.

“…Brillo: El esmalte dental tiene un alto grado de capacidad para reflejar la luz que se irradia sobre él, lo que le da un alto grado de valor, su brillo superficial es debido al grado de mineralización de su contenido y la regularidad perfectamente pulida de su superficie, este brillo disminuye con el tiempo por uso y el efecto de los ácidos existentes en la boca. 28 Luminiscencia: El esmalte dental armoniza dos fenómenos ópticos, fluorescencia y fosforescencia, los mismos son producidos cuando son irradiados con una luz de onda corta. 31 Radio opacidad: Es muy alta en el esmalte, dado que es la estructura "más radiopaca" del organismo humano dado su elevado nivel de mineralización.…”
