“…Resin cements chemically bond to both the ceramic substrate as well as the tooth substance, and thereby reinforce the tooth-reconstruction complex [5,6,[9][10][11][12][13]. Furthermore, their high translucency and tooth-resembling color improve the esthetic result [13].…”

This study tested the impact of Gluma Desensitizer on the tensile strength of zirconia crowns bonded to dentin. Human teeth were prepared and randomly divided into six groups (N = 144, n = 24 per group). For each tooth, a zirconia crown was manufactured. The zirconia crowns were cemented with: (1) Panavia21 (PAN), (2) Panavia21 combined with Gluma Desensitizer (PAN-G), (3) RelyX Unicem (RXU), (4) RelyX Unicem combined with Gluma Desensitizer (RXU-G), (5) G-Cem (GCM) and (6) GCem combined with Gluma Desensitizer (GCM-G). The initial tensile strength was measured in half (n = 12) of each group and the other half (n = 12) subjected to a chewing machine (1.2 Mio, 49 N, 5°C/50°C). The cemented crowns were pulled in a Universal Testing Machine (1 mm/min, Zwick Z010) until failure occurred and tensile strength was calculated. Data were analyzed with one-way and two-way ANOVA followed by a post hoc Scheffé test, t test and Kaplan-Meier analysis with a Breslow-Gehan analysis test ( = 0.05). After the chewing simulation, the self-adhesive resin cements combined with Gluma Desensitizer showed significantly higher tensile strength (RXU-G, 12.8 ± 4.3 MPa; GCM-G, 13.4 ± 6.2 MPa) than PAN (7.3 ± 1.7 MPa) and PAN-G (0.9 ± 0.6). Within the groups, PAN, PAN-G and RXU resulted in significantly lower values when compared to the initial tensile strength; the values of all other test groups were stable. In this study, self-adhesive resin cements combined with Gluma Desensitizer reached better long-term stability compared to PAN and PAN-G after chewing simulation.

“…Moreover, their useful properties of minimal solubility, stability, and biocompatibility greatly contribute to the formation of strong and durable tooth-restoration interfaces, with minimal removal of adjacent tooth tissue 3,4) . However, adhesion of luting resin cements to processed composites has been difficult to achieve.…”

Evaluation of Physical Properties and Surface Degradation of Self-adhesive Resin Cements

This study sought to evaluate the pH value, film thickness, filler particle percentage, and morphological changes of selfadhesive resin luting cements. Products tested were G-Cem, Maxcem, Smart Cem, and RelyX™ Unicem. Cement pH was measured with pH test paper. Filler particle percentage was calculated after cement samples were incinerated at 750℃. To test film thickness, mixed cements were placed between two glass plates and compressed using a loading device. For morphological changes, specimen surfaces were observed by SEM after treatment with various media. There were significant differences among the cement pH values measured at 20 seconds after light curing, and at 90 seconds and 48 hours after mixing. Filler particle percentage was directly proportional to film thickness. Degradation of cement surfaces was also detected after surface polishing and immersion in water, acetic acid, and acetone. In conclusion, significant differences were found in the surface properties of the materials tested, and these differences might lead to differences in their clinical performance.

“…Besides the formation of complex compounds with calcium ions, different kinds of physical interactions such as hydrogen bonding or dipole-to-dipole interactions were supposed to favorably affect the adhesion of this self-adhesive cement. 33 The different microleakage results of the selfadhesive cements may be explained by their different functional monomers and different chemical compositions. Differences in pH values may affect the etching ability of these cements to enamel and dentin, resulting in less than ideal adhesion with subsequent microleakage.…”

Although self-adhesive resin cements reduce the duration of the luting process, their universal practice requires caution because the microleakage performance of some brands is very poor. SUMMARYObjective: To assess the microleakage of three self-adhesive and one etch-and-rinse resin cements when luting IPS Empress 2 (Ivoclar Vivadent, Liechtenstein) all-ceramic inlay restorations to the prepared cavities in extracted human molars.Methods: The cylindrical Class V cavities were prepared on the buccal surfaces of 40 extracted human third molars using diamond burs. The IPS Empress 2 ceramic inlays were placed with Multilink Sprint (Ivoclar Vivadent), RelyX Unicem (3M ESPE, USA), G-Cem (GC, Japan), or Variolink II (Ivoclar Vivadent) as the control group. After storage in distilled water at 378C for 24 hours, samples were subjected to 1000 thermal cycles between baths of 58C and 558C, with a dwell time of 30 seconds. The microleakage scores were examined on the occlusal and gingival margins at 303 magnification after each sample was stained with 0.5% basic fuchsin and sectioned into three parts using a thin diamond blade (Isomet, Buehler, USA) (n=40). The extent of microleakage on both occlusal and gingival margins of the restorations was scored and recorded. The
