Evaluation of Laser Speckle Contrast Imaging for the Assessment of Oral Mucosal Blood Flow following Periodontal Plastic Surgery: An Exploratory Study

Figure 2

Time-course of the changes of gingival blood flow (BF) in zone A, expressed in Laser Speckle Perfusion Unit (LSPU). Time points include preoperative data (bsl.) and postoperative days (1 to 180). Data are presented as means ± SE. In (a, b), statistically significant differences in the postoperative values versus bsl. are indicated by × in Geistlich Mucograft () and by + in CTG (). The differences between grafts at the respective time points are indicated by #. In (c, d), the same data are shown in a different grouping as gender differences are depicted separately for Geistlich Mucograft and for CTG. indicates significantly different time points between the genders. ×, +, #, and mark significance levels of after being adjusted by the Benjamini and Hochberg method.
