“…Researchers proposed a relationship between resindentin bond strength and quantity of nanoleakage expression because high bonding strength corresponds to low nanoleakage with the following characteristics: adequate adhesive infiltration; few residual solvent; and complete polymerization of resin monomers 16) . However, this relationship is complex and remains controversial.…”

“…Depending on various high-resolving power microscopes, nanoleakage can be observed. Light microscope (LM) [13][14][15] , fieldemission scanning electron microscope (FESEM) 8,16,17) , and transmission electron microscope (TEM) 13,18) are the most commonly used qualitative or quantitative nanoleakage observation methods. However, under different approaches, whether the bonding interfaces from the same tooth could produce similar images and statistical results is still unknown.…”

The purpose of this study was to evaluate the capability and characteristics of different nanoleakage observation methods, including light microscope (LM), field-emission scanning electron microscope (FESEM), transmission electron microscope (TEM), and confocal laser scanning microscope (CLSM). Dentin specimens were bonded with either an etch-and-rinse adhesive (SBMP) or a self-etch adhesive (GB), and prepared for nanoleakge evaluation according to different observation methods. LM, FESEM and CLSM results demonstrated that the SBMP group showed more interfacial nanoleakage than the GB group (p<0.05); by contrast, no significant difference was found in TEM results (p>0.05), however, TEM illustrated concrete nanoleakage forms or patterns. The results suggested that different observation methods might exhibit distinct images and a certain degree of variations in nanoleakage statistical results. Researchers should carefully design and calculate the optimum assembly in combination with qualitative and quantitative approaches to obtain objective and accurate nanoleakage evaluation.

“…A progressive decrease in degree of conversion of composites is observed by increasing the silica particle size as a result of an increase in filler percentage in the composites and light scattering during curing 35) . We used micro-Raman in situ to determine the CD of dentin adhesives 40) . Our results are slightly greater than reported in other studies with FTIR spectroscopy [41][42][43] .…”

The aim of the study is to determine the influence of the type of bracket, on bond strength, microhardness and conversion degree (CD) of four resin orthodontic cements. Micro-tensile bond strength (µTBS) test between the bracket base and the cement was carried out on glass-hour-shaped specimens (n=20). Vickers Hardness Number (VHN) and micro-Raman spectra were recorded in situ under the bracket base. Weibull distribution, ANOVA and non-parametric test were applied for data analysis (p<0.05). The highest values of ή as well as the β Weibull parameter were obtained for metallic brackets with Transbond™ plastic brackets with the self-curing cement showing the worst performance. The CD was from 80% to 62.5%.

“…Hass et al [31] was recently able to demonstrate that there is a strong correlation between the degree of conversion of adhesive systems and μTBS values. Another way, a good performance of an adhesive system to bond with the dentin depends on countless factors.…”

ObstractThis study evaluated microtensile bond strength (µTBS), degree of conversion, modulus of elasticity and ultramicrohardness of three etch-and-rinse adhesives systems. The materials evaluated were: Ambar (FGM), Optibond (Kerr) and Magic Bond (Vigodent). The degree of conversion was analyzed by FTIR/ATR. To evaluate bond strength (μTBS) in dentin, 15 teeth (n = 5) were restored and sliced to obtain the specimens (0.8mm 2 ). The dynamic ultra microhardness tester was used to evaluate the hardness and modulus of elasticity. The Magic Bond adhesive system showed lower µTBS than Ambar and Optibond (p <0.001). For degree of conversion, comparisons between groups of adhesive systems evaluated showed statistically significant difference (p<0.001), with higher values for Ambar and Optibond when compared a Magic Bond. For modulus of elasticity and ultramicrohardness, Ambar and Magic Bond showed lower values than Optibond. The best results in all properties evaluated were obtained by the Optibond adhesive system.
