Development of palatal inflammation, erythema, and edema. (A) Clinical score: 0, no signs of disease; 1, pinpoint erythema/edema; 2, diffuse erythema/edema. Results represent the averages of 3 independent experiments. (B) Uninoculated control rat palate. (C) Inoculated rat palate tissue underlying denture at week 4 postinoculation. The arrow points to an area of pinpoint erythema and edema (clinical score, 1). (D) Inoculated rat palate tissue underlying denture at week 6 postinoculation. Arrows point to areas of diffuse erythema and edema; note that the palatal ridges are not visible due to swelling (clinical score, 2). Images are representative of 3 independent repeats.
