Figure 1. Low-power photomicrograph of the measured periodontal tissues. (a) Hematoxylin-eosin-stained tissue section, 20X. Three measurements of the gingival width were done for each case, considering the distance from the periosteum of the alveolar bone up to the basal membrane underlying the squamous epithelium, as indicated by black arrows. (b) The graph shows an increase in mean width of the nifedipine group (n = 17) and cyclosporin group tissue (n = 7), compared with the control group (n = 8), but only statistical significance for the cyclosporin group vs. the control group (*p < 0.05). The data are expressed as the mean ± SD.
