“…Furthermore, applying a glass ionomer cement resulted in a higher fracture resistance and not in a less advantageous fracture mode, though other authors did not recommend conventional cementation of FRC posts, Table 3 Mean force at fracture with standard deviations in Newton (N) Table 4 Frequencies of failure modes in the six tested groups due to low bond strength values to post and root dentin 39,40) . Though not statistically significant, there was a decrease of fracture load evident in the groups with adhesively luted posts only.…”

The aim of the study was to evaluate the influence of fatigue and cementation mode on the fracture behaviour of endodontically treated bovine incisors restored with fiber-reinforced-composite (FRC) posts and crowns. Forty-eight endodontically treated incisors were restored with FRC posts, composite build-ups, and cast crowns. In 16 teeth, each of the posts were cemented conventionally with KetacCem (3M Espe) or adhesively with Panavia F (Kuraray) or RelyXUniCem (3M Espe). One-half of the specimens in each group were subjected to thermal cycling with 10,000 cycles at 5-55°C and mechanical aging, loading the specimens in 1,200,000 cycles with 50 N. Fracture resistance was determined by loading the specimens until fracture at an angle of 45°. The loading test showed that cementation mode and fatigue testing had an influence on the load bearing capability. Before fatigue testing no statistically significant differences between the different cementation modes could be detected. After fatigue testing, conventionally cemented FRC posts lead to statistically significant higher fracture loads compared to adhesively luted posts. Most specimens fractured in a favourable way, independent from the type of cementation.

“…There are reports that thinning of the root canal wall due to inserti on of the post reduces fracture resistance (15), and that bonding the post to the root canal wall (16,17) or the presence of a ferrule (18) increase fracture resistance. There have recently been numerous reports of fiber posts in relation to root fracture, but in vitro findings are inconclusive, for example, one study observed that fiber posts increase fracture resistance (19) and another reported deterioration resulting from fiber posts (20).…”

“…The use of resinous cement, possibly due to adhesion, has been demonstrated to have a slight superiority compared to other types of cements [12][13][14][15]31,33], being indicated in all cases and cementing with correct cavity cleaning, aiming to eliminate eugenol from endodontic cements, which could alter the adhesive properties of resin cements [34]. In this study, the results obtained with resin cement were similar to glass ionomer cement.…”

“…Studies in literature have assessed the adhesion of intraradicular posts cemented with different cements [12][13][14][15], as well as the fracture resistance of bovine roots restored with different prefabricated posts [16]. Coronal microleakage was assessed by dye ink, comparing posts and cores cemented with permanent and temporary cements, showing that teeth restored with permanent cements had better sealing [17].…”

Objective: To assess the sealing capacity of different dental cements regarding apical microleakage on teeth with prefabricated posts. Material and Methods: Forty-eight single-rooted teeth were selected and, after having their coronal part removed at 10mm standard, underwent endodontic cleaning and preparation. The space for the post was prepared with # 3 Largo bur at 7 mm standard value. The study included the following groups: Group I, post prefabricated with # 1 intracanal glass fiber cemented with zinc phosphate cement (n = 12); Group II, post prefabricated with # 1 intracanal glass fiber cemented with conventional glass ionomer cement, Vidrion C (n = 12); Group III, post prefabricated with # 1 intracanal glass fiber cemented with chemical action resin cement, Multilink (n = 12). Two groups of six teeth each were also included, one as negative control group and the other as positive control. After cementing, teeth were tested through a dual-chamber experimental model, using Enterococcus Faecalis for apical contamination. Results: The control groups behaved as expected: positive control group with total contamination in 11 days and negative control group without any contaminated specimen within observation time of 60 days. Group I showed microleakage in all specimens for up to 29 days (100%). Group II and Group III showed microleakage in 50 and 49 specimens (83.33% and 75%) respectively along the research time of 60 days. Group 1 showed microleakage in all specimens for up to 29 days (100%). Group 2 and Group 3 showed microleakage in 50 and 49 specimens (83.33% and 75%) respectively along the research time of 60 days. The Log-Rank test showed differences between Groups 1 and 2 (p<0.05) and between Groups 1 and 3 (p<0.05). However, there was no difference between Groups 2 and 3 (p> 0.05). The results showed higher delay in bacterial infiltration in Groups 2 and 3 when compared to Group 1. Conclusion: No cement completely prevented infiltration during the experimental period. Zinc phosphate cement had the lowest apical sealing capacity while glass ionomer cement and resin cement showed similar results.
