Abstract
Recently, conservative approach for restoration of endodontically treated tooth in order to reinforce the tooth structure is being widely accepted due to improvement of reliable bonding systems. However, there are a few studies that evaluated the fracture resistance of endodontically treated lower premolar with ideal access opening restoring different types of bulk-fill resin composites in comparison to the use of other resin-based materials. The objective of this study was to compare the fracture resistance among endodontically treated lower premolars restored with different core build-up materials. Seventy-five human single-rooted mandibular premolar were randomly divided into five groups (n=15): Group I (control group) was sound teeth while Groups II-V were endodontically treated teeth restored with the following resin-based materials after removal of gutta percha 3 mm below the cementoenamel junction (CEJ): Group II, dual-cured composite core build-up material; Group III, nanohybrid resin composite; Group IV, high viscosity bulk-fill resin composite; and Group V, low viscosity bulk-fill resin composite and nanohybrid resin composite. All the specimens were subjected to compressive loading at a 45° angle to the long axis of the tooth until fracture occurred. The data were statistically analyzed using a one-way analysis of variance and Chi square test. The description of the reliability and probability of failure of fracture strength was analyzed by Weibull statistics. Sound tooth had statistically significant difference from the endodontically treated groups (p<0.05) while the endodontically treated groups were found no significant differences in fracture resistance values and the Weibull modulus (p>0.05). All the five groups exhibited a higher percentage of unfavourable failures than favourable failures. In conclusion, the different types of resin-based materials that restored the endodontically treated lower premolar exhibited similar fracture resistance and failure patterns. Consequently, endodontically treated lower premolars with ideal access openings could be restored using any type of resin-based materials.
