“…As done by Vineet et al, fibres were positioned differently on the gingival and pupal floor in this study. 2 In totalling, fracture resistance upsurges when fibres are placed close to point where force is exerted as it leads to a shorter working arm according to levers principle. 18,19 In a study conducted by Jafari Navimipour et al 6 over and under the restoration with glass fibre greatly boosts fracture resistance.…”

“…An optimal dental restoration can maintain a tooth's appearance and functionality, protect remaining tooth structure & prevent micro leakage. 1,2 The dental structure has been strengthened significantly by modern adhesive techniques and composite resins. Higher clinical performance with lower polymerization shrinkage & enhanced resistance to withstand stresses of mastication has been made possible by the emergence of newer dental composites with improved qualities as a result of considerable research and molecularlevel advancements.…”

“…Higher clinical performance with lower polymerization shrinkage & enhanced resistance to withstand stresses of mastication has been made possible by the emergence of newer dental composites with improved qualities as a result of considerable research and molecularlevel advancements. 2,3 While this, the composite resin lacks toughness rather than strength or stiffness despite being a rigid material. Toughness is interpreted as ability of material to captivate energy to rapid propagation of cracks.…”

To examine & assess how varied InterligTM glass fibre placement & orientation affect fracture resistance of large class II cavities in maxillary premolars -An In Vitro study. Class II (MOD) cavities were organized with uniform dimensions on 50 extracted human maxillary premolars, and samples were erratically distributed into 5 groups (n = 10 each) as follows: Group I contains composite materials; Group II contains composite + horizontal Interlig placement on the gingival & pulpal floors; Group III contains composite + horizontal Interlig placement only on the pulpal floors; Group IV contains composite + vertical Interlig placement on the gingival & pulpal floors; and Group V contains composite + Interlig chips. Fracture resistance of all samples was tested using universal testing machine following restorations and the thermocycling process. Under a stereomicroscope, the fracture modes were examined. One-way ANOVA & Tukey test were used to analyse data, with significance values of P 0.05. The fracture strength of control group was 736.8640 N while it was 1233.4480 N for group 2, 1223.2260 N for group 3, 1185.0440 N for group 4 and 797.5600 N for group 5. Fracture strength of group 5 was more than other groups except for group 1, there was no statistically substantial modifications. Fortification of composite with fiber does upsurge fracture resistance of wide Class II mesio-occluso-distal premolars cavities significantly.

“…Teeth with more intact coronal tooth structure tend to have better resistance to fractures. Some studies have explored the utilization of fiber posts and other reinforcement materials to increase the FR of the obturated teeth [ 24 , 25 ]. These reinforcement techniques can provide additional support to the tooth and improve its resistance to fractures.…”

Introduction The utilization of endodontic sealers is of paramount importance in ensuring the sustained efficacy and resilience of endodontic treatment. The primary objective of the research was to appraise and contrast the fracture resistance (FR) of three distinct categories of endodontic sealing materials that are frequently employed in the context of endodontic therapy. Materials and methods This research used an in vitro experimental design. Sixty single-rooted human teeth indicated for extraction were utilized according to established protocols. These teeth were then arbitrarily divided into four piles, one for each of the four possible sealants. All specimens were put through a standardized thermal cycling procedure to simulate clinical conditions after the root canals were obturated. The subsequent step involved testing the FR of each group by utilizing a universal testing machine up until failure. Any statistically significant difference in FR among the three sealing materials was identified through appropriate statistical analysis. Results Group 1, which utilized a particular sealing material, exhibited the highest mean fracture resistance, measuring at an impressive 1198.33 ± 321.4 Newtons (N). A post hoc analysis was done to see the exact differences between each group and statistically significant differences between Groups 1 and 2 (p<0.05), Groups 1 and 4 (p<0.05), and Groups 3 and 4 (p<0.001) were observed. Conclusion The FR of Group 1 specimens were noticeably greater than those of Group 2 and Group 4 while the FR of Group 3 specimens was more than that of the Group 4 specimens. This study provides important insights into the fracture resistance of various endodontic sealing materials.

“…The fibres are placed such that its (composite material) longitudinal axis is aligned perpendicular to the compressive forces to increase the strength of restoration. However, if the longitudinal axis of fibre is parallel to compressive forces, no enhancement will occur in restoration [ 16 – 18 ].…”

The objective of this study was to compare the effects of using short and continuous fibres for repairing compression-induced tooth crown damage. Human teeth were used for the study. They were upper medial incisors and maxillary first premolars lost due to periodontal causes. The teeth were divided into two groups with Hahnenkratt and short glass fibres. Teeth compressive strength tests were carried out. Then micro-CT imaging of the teeth and their fractures obtained after compression was performed. The teeth restored with Hahnenkratt’s glass fibre posts showed higher compressive strength than the teeth restored using the EverX Posterior material. The tooth’s most weakened and sensitive point after endodontic treatment was the cervical area of the tooth. All cracks were parallel to the root canal.
