    Abstract

    This study was conducted to evaluate the influence of the C-factor on the bond strength of a 6th generation self-etching system by measuring the microtensile bond strength of four types of restorations classified by different C-factors with an identical depth of dentin.

    Eighty human molars were divided into four experimental groups, each of which had a C-factor of 0.25, 2, 3 or 4. Each group was then further divided into four subgroups based on the adhesive and composite resin used. The adhesives used for this study were AQ Bond Plus (Sun Medical, Japan) and Xeno III (DENTSPLY, Germany). And composite resins used were Fantasista (Sun Medical, Japan) and Ceram-X mono (DENTSPLY, Germany).

    The results were then analyzed using one-way ANOVA, a Tukey's test, and a Pearson's correlation test and were as follows.

    1. There was no significant difference among C-factor groups with the exception of groups of Xeno III and Ceram-X mono (p < 0.05).

    2. There was no significant difference between any of the adhesives and composite resins in groups with C-factor 0.25, 2 and 4.

    3. There was no correlation between the change in C-factor and microtensile bond strength in the Fantasista groups.

    It was concluded that the C-factor of cavities does not have a significant effect on the microtensile bond strength of the restorations when cavities of the same depth of dentin are restored using composite resin in conjunction with the 6th generation self-etching system.

    Groups with C-factor 0.25 were prepared on the flat ground dentin surfaces. For the other experimental groups, the cavities were prepared below the ground dentin surfaces.
