Aim: Comparative assessment of fracture resistance of roots obturated with three hydrophilic systems - novel CPoint system, Resilon/Epiphany system, and EndoSequence BC sealer; and one hydrophobic gold standard gutta-percha/AHPlus system. Materials and Methods: Ninety freshly extracted, human, single-rooted mandibular premolars were selected. The specimens were decoronated and standardized to a working length of 13 mm. The teeth were randomly divided into six groups (n = 15). In Group A, teeth were left unprepared and unfilled (negative control). Rest of the groups were prepared by using ProTaper system up to a master apical file F3; followed by which Group B was left unobturated (positive control); Group C, novel CPoint System; group D, Resilon/Epiphany system, Group E EndoSequence BC sealer, and Group F gutta-percha and AH Plus. Specimens were stored for 2 weeks at 100% humidity. Each group was then subjected to fracture testing by using a universal testing machine. The force required to fracture each specimen was recorded and the data was analyzed statistically using analysis of variance (ANOVA) test and Tukey's post-hoc test. Results: The hydrophilic obturation systems have shown to exhibit significantly higher fracture resistance as shown by the values in Groups C, D, and E (P < 0.05) when compared with Group F. Within hydrophilic groups there was significant difference between Group D and Groups C and E (P < 0.05), while Groups C and E had no significant difference (P > 0.05). Conclusion: In contrast to hydrophobic systems, hydrophilic systems showed higher fracture resistance in a single-rooted premolar.
