Fig. 6. Collagen score on gingival histopathology using the MT method. *Data are presented as mean ± standard deviation. For each treatment, testing was carried out in four repetitions. * NC: Negative control, PC: Positive control (Bacterial induced rats), BC: BC control (1 × oral BC applied), CC: Comparative Control (1× kenalog cream applied), SWC1: Sappan Cream 1 (PC + 1 times cream applied), SWC2: Sappan Cream 2 (PC + 2 times cream applied). Different superscripts (a,b,c,d) mark significant differences among treatment based on Tukey HSD post hoc test (p < 0.05). The black arrows indicate the collagen site on the gingival tissue. SC: stratun corneum; C: collagen; SB: stratum basalis.
