There are two objectives of this experiment. The first objective is to investigate the deformation properties of cyanoacrylate used as a topical bridge adhesive rather than a contact adhesive. The second objective is to examine the differences of cyanoacrylate compared to traditional stitches in terms of their suture performance. For the purposes of this study, suture performance is defined as the vertical deformation of the “suture region” (the band including and surrounding the incision in which either the glue or the stitches reside). A one-tail t-test assuming unequal variances will be performed to compare the reference line-gap strains of stitched and cyanoacrylate-cured samples. The proposed hypothesis of the study is that cyanoacrylate will increase the suture performance by decreasing the deformation of the “suture region”, due to the uniform contact of the adhesive with the sides of the material.

In addition to the main hypothesis, an additional objective is to investigate whether the strain of both halves of the sample are equal. It is hypothesized that the strain will be symmetric for both halves of the sample. A two-tailed t-test assuming equal variances will be performed comparing the strains of reference line gap 1-2 to gap 5-6. Symmetric strain will be investigated for all 10 samples.
