“…The ideal dental cement material is biocompatible, inhibits plaque formation, has a proper film thickness, is insoluble in oral fluids, and possesses good mechanical properties. − Although a variety of dental cement compositions are available on the market, no current standard has been established to help with dental cement selection. In fact, dental cement selection is usually done out of familiarity with a particular cement, ease of mixing and delivery processes, physical material properties, cost, and current trends in conventional restorations. ,,, However, some cement compositions might be unknowingly advantageous for the inhibition of biofilm formation while ensuring minimal adverse dental tissue reaction. Therefore, these cements could reduce the risk of developing peri-implant disease and could consequently prolong the lifetime of the restoration.…”

Cement-retained restorations on dental implants are a well-established method to replace missing teeth. However, undetected residual cement left during crown cementation procedures encourages microorganism growth, and it has been identified as a risk factor for peri-implant disease. Currently, there is no official guidance for dental cement selection, and the increasing variety of available compositions intensifies the complexity of the clinicians’ decision process. The present study aimed to evaluate the in vitro host and bacterial cellular response to four different commercial dental cements as well as their effects on cement surface morphology. Disk specimens (n = 3) of bioceramic, zinc phosphate, resin-modified glass ionomer, and resin cements were exposed to host (murine pre-osteoblasts, human gingival fibroblasts, and undifferentiated human macrophages) and oral bacterial (Streptococcus mutans, Streptococcus salivarius, Streptococcus sanguinis, and Aggregatibacter actinomycetemcomitans) cells. Results indicated that oral bacteria degraded the cement surface, but bacterial viability was not significantly affected by the presence of dental cement. Conversely, the biocompatibility and morphology of host cells were severely impacted by the cement composition. Only the bioceramic cement achieved >70% viability for all cell lines investigated. Within the limitations of this study, the results indicated the importance of considering the biological interactions of a dental cement composition during selection as it played a significant role in the host cellular response and the degree of surface degradation due to bacterial attack.

“…Lack of adhesion between the resin matrix and the particles, incomplete wetting of the surface of the particles, or unevenly distributed particles in the matrix may reduce the strength. The base and catalyst of Panavia are deposited on a mixing pad and mixed by hand for 20 s. Compared to auto‐mixed cements, Panavia might have a greater risk of an inhomogeneous mixture, which affects both laboratory testing and clinical performance [7].…”

“…Their major advantage is greater adhesion between cement and ceramic and between cement and dental tissue compared to water‐based cements [3–5]. Resin‐based cements are easy to handle, have a fast and regulated setting, and the potential for both mechanical and chemical adhesion [6,7]. Resin cements with different setting modes are available.…”

The purpose of the study was to measure the cement thickness obtained when ceramic rods were luted to dentin and to analyze the relation between cement thickness and the previously published tensile bond strength of similar test specimens. In addition, the ISO standard 4049:2019 method was used to determine the film thickness of the used cements. Zirconia (n = 100) and lithium disilicate (n = 50) rods were cemented to bovine dentin using one of five different resin‐based cements. The ceramic‐dentin test specimens were cut into two slices and the cement thickness was measured using a scanning electron microscope and compared to the bond strength values of similar specimens already published. The mean cement thickness recorded for ceramic rods cemented to dentin was in the range 20–40 μm, which was larger than the cement film thickness found by the ISO method. The cement film thickness determined according to ISO standard methods did not concur with the results obtained when cementing ceramic rods to dentin. For cementing ceramic restorations, a cement thickness in the range 25–35 μm seems to be favorable for the bond strength.

“…The automix versions for both cements were used in this study. It has been reported that automixed resin composite cements demonstrate significantly higher mechanical properties (in particular, compressive strength) than their hand-mixed variants [10]. The use of self-etching and self-adhesive resin composite cements is clinically advantageous as it shortens the chairside time, and also eliminates the guesswork on the substrate characteristics, specifically in terms of moisture [11].…”

The aim of this in vitro study was to evaluate the adhesion strength of two new fiber post systems (FiberSite™ Post and Cytec™ Blanco Post) cemented with two different adhesive resin cements (Panavia™ SA and Maxcem™ Elite). Root canals of sixty extracted human mandibular premolars were prepared using ProTaper Universal™ rotary files (Dentsply Sirona Endodontics, York, PA, USA). The root canals were irrigated with 5.25% sodium hypochlorite (NaOCl) during instrumentation. After root canal preparation, the canals were irrigated with 2 mL of 17% EDTA (1 min), followed by 2 mL of 5.25% (5 min) NaOCI, and 2 mL saline. The root canals were dried with paper points and divided randomly into two study groups (n = 30) according to the type of post system: Group 1, FiberSite™ Post (MegaDental, Partanna, Italy); and group 2, Cytec™ Blanco Post (Hahnenkratt, Königsbach-Stein, Germany), with one of the two adhesive resin cements: Subgroup A, Panavia™ SA Cement Plus Automix (Kuraray, Osaka, Japan); subgroup B, Maxcem™ Elite (Kerr, Orange, CA, USA). Following thermocycling, the adhesion strength was evaluated using the push-out adhesion (bond) strength test. Fractographic analysis was performed using stereomicroscope. The data were analyzed using two-way analysis of variance (p = 0.05). The adhesion strength values of both the posts were significantly higher when cemented with subgroup B (Maxcem™ Elite). The highest adhesion strength value was demonstrated by group 1B (FiberSite™ post cemented with Maxcem™ Elite cement). The type of post did not have a significant impact on the bond strength values for either cement material.
