“…From this study we found that maximum fracture resistance was observed with zirconia posts. Pruthi et al (2018) assessed the fracture resistance of different fiber reinforced posts and concluded that, parallel posts to have better retention than tapered and double tapered posts [ 1 ]. Saritha et al (2017) evaluated the fracture resistance of carbon, zirconia and glass fiber post and found that zirconia had good fracture resitance similar to our results [ 5 ].…”

Teeth with crown structure less than 50% can be restored. Therefore, it is of interest to evaluate an in vitro efficacy of Zirconia post, Glass fiber post, polyethylene-woven fiber posts, and Quartz posts. Forty eight recently extracted mandibular first premolar teeth were randomly grouped in to 4 different groups with 12 samples in each group. After endodontic treatment samples in all groups underwent post preparation followed by restoration with respective posts. The mean fracture resistance (Newton) were 463.5 ą 14.3 (Group I) 425.2ą 23.5 (group II), 410.4ą 18.6 (Group 3) and 385.2 ą 14.2 (group 4). Data shows that Zirconia post had highest fracture resistance compared to other tested groups.

“…Esthetics and structural durability plays a major role in treatment outcome of endodontically treated teeth. There has been an increased demand for endodontic post and core materials for destructed endodotically treated teeth [ 1 ]. Teeth with crown structure less than 50% can be restored with post and core.…”

A BSTRACT Aim: The aim of this study was to determine if there is any difference in fracture resistance between different post sizes and lengths when more than one post is involved. Materials and Methods: Thirty extracted maxillary first premolars were endodontically treated and divided into three groups: In Group 1 (control group), no post space preparation was conducted and access cavities were restored with composite; in Group 2 (single post), post space preparation of 10 mm was carried out only in one of the canals; and in Group 3 (double post), post space preparation of 5 mm was conducted in both the canals. Appropriately sized glass fiber posts were cemented in Groups 2 and 3 followed by core buildup. The fracture resistance of the specimen was measured using a universal testing machine and the data analyzed. The mean fracture resistance values of the three groups were compared applying one-way analysis of variance (ANOVA) followed by post hoc Tukey’s test. The data were analyzed using Statistical Package for the Social Sciences software program, version 15.0. South Asia, Bangalore. Results: The control group had a significantly lower fracture resistance value as compared to Groups 2 and 3. No statistically significant difference was observed in the fracture resistance between Groups 2 and 3. Conclusions: No significant difference was observed between the fracture resistance of endodontically treated maxillary first premolars restored with size 3 single post of longer length and size 1 double posts of shorter lengths.

“…In the present study, for standardization, parallel posts space was prepared which probably deprived additional mechanical retention provided by small undercuts present in the canal therefore, prefabricated serrated parallel side posts (both carbon and glass fiber post) were used, which provided additional retentive features, as they get embedded into the resin luting cement and resist dislodging forces on pulling.

Aims:The aim of this study is to determine the mean failure load for each postsystem and the relationship between post lengths with the mean failure loads.Materials and Methods:Ninety single-rooted decoronated mandibular premolar teeth were endodontically treated and randomly assigned to three groups with respect to their post length (2/3rd and ½ of the root length). The first two groups were randomly divided into four subgroups, restored with the following postsystem: polyethylene-woven fiber posts, glass fiber tape, prefabricated carbon, and glass fiber posts. A composite core with no post served as control. All posts were cemented using dual-cure resin cement, and the same was used for core buildup. The standard cores were formed in each group. All the specimens were tested in a universal testing machine, and the load was calculated.Results:One-way analysis of variance (ANOVA) showed that prefabricated glass fiber post had significantly highest fracture resistance when compared to other prefabricated and custom fiber-reinforced composite posts. Two-way ANOVA demonstrated no significant difference among the post lengths.Conclusion:The results of this study showed that glass fiber posts showed higher fracture load, but post length did not significantly increase the fracture resistance of endodontically treated teeth.
