“…A recent study by Ishwarya et al compared the bond strength and mode of failure of glass fiber posts luted using two different adhesives and concluded that superior bond strength was seen in two-step etch and rinse adhesives rather than self-etch adhesives due to enhanced resin cement penetration into the dentinal substrate [ 26 ].…”

This study aims to evaluate the retention of fiber posts in the coronal, middle, and apical dentin regions with various bonding techniques by using fifth, sixth, and eighth-generation bonding agents and self-etch adhesive cement. Materials and methodsFor this study, 96 freshly extracted human incisors with straight roots were selected. Endodontic treatment of the specimens was performed. The post spaces were created immediately after obturation and the posts were luted with three different bonding agents and self-adhesive resin cement and the specimens were divided into four groups. Approximately 3 mm thick sections were made from different dentin regions of the post space and were tested for three subgroups: Subgroup I: Coronal, Subgroup II: Middle, Subgroup III: Apical. The specimens were tested on a universal testing machine. ResultsStatistical analysis was done using one-way analysis of variance (ANOVA) and Tukey's post hoc test using SPSS software version 17.0 (SPSS Inc., Chicago ). The intra-group comparison showed that the bond strength was more in the fifth-generation bonding agent (

“…The type of failure was assessed using Stereomicroscopy (10x). Failures were classified as:  Type 1: Adhesive failure between post and luting cement  Type 2: Adhesive failure between dentin and luting cement  Type 3: Cohesive failure of post system  Type 4: Cohesive failure of luting cement  Type 5: Mixed type; combination of any two of the above-mentioned types [6] .…”

The aim of this study was to assess the fracture resistance of endodontically treated maxillary premolars with mesioocclusodistal (MOD) cavities supported by horizontal glass fiber posts. Methodology: Thirty three extracted maxillary premolars were collected and grouped into three. MOD cavities were prepared and all of them were endodontically treated. Teeth were supported with horizontal glass fiber posts; vertical glass fiber posts and composite restoration alone in the three groups respectively. Fracture resistance assessed using Universal testing machine. Type of fracture was assessed using visual examination. Type of failure was assessed using Stereomicroscope. Results: Highest fracture resistance was shown by samples supported by horizontal fiber post (Group C). Group B had higher chances of Type 1 failure (Adhesive failure between post and luting cement) compared to other groups. Group A had higher chances of Type 4 failure (Cohesive failure) and Group C had higher chances of Type 5 failures (Mixed type; combination of any two of the above-mentioned types).There was no statistically significant association between groups and fracture mode (repairable and unrepairable). Majority of samples from Group A and Group C underwent repairable fractures. Conclusion: Fracture resistance of horizontal fiber post group was significantly higher compared to the other two groups.

BACKGROUND Endodontically treated teeth have higher fracture rate due to pronounced coronal destruction. The minimally invasive approach of associating adhesive techniques and posts seems to contribute to a better clinical prognosis for endodontically treated teeth. The purpose of this study was to evaluate the push out bond strength and mode of failure of fiber post using one self-etch resin cement and two selfadhesive resin cements. METHODS Sixty single rooted teeth were selected and decoronated 2 mm coronal to cementoenamel junction (CEJ). The teeth were prepared and obturated, then divided into three groups of 20 samples each. The post spaces were prepared and relyX fiber posts were cemented in group I with multilink N, in group II with relyX U200 and in group III with Maxcem elite luting cements. The specimens were sectioned into three slices of 2 ± 0.1 mm thickness to perform the push out test using universal testing machine. Failure modes were evaluated using scanning electron microscope. Thus, collected data was statistically analysed using one-way analysis of variance test. RESULTS The push out bond strength of group I was significantly higher than that of group II and group III (P < 0.05). No statistically significant difference was found between group II and group III. There was significant difference between coronal, middle and apical thirds in each group. The mode of failures showed 78 % of the samples had adhesive failure while 22 % of the samples had mixed failure. CONCLUSIONS Multilink N was found to be significantly more effective than RelyX U200 and Maxcem elite. Most common type of failure observed was adhesive failure between dentine-cement interface.
