Scoring systems used for evaluation of lesions.

Caudal stomatitis intensity score
The investigator scores the intensity of the inflammatory lesions on both sides, ie, the right and the left separately.
Score	Description
0	Absence of lesion
1	Slight inflammation, no ulceration, no proliferation, no spontaneous bleeding, no bleeding induced by gentle pressure
2	Mild inflammation, no ulceration, no or slight proliferation, no spontaneous bleeding, no bleeding induced by gentle pressure
3	Moderate inflammation, ulcerative or ulcero-proliferative lesion may be observed, no spontaneous bleeding but bleeding induced by gentle pressure on the lesions
4	Severe inflammation, ulcerative or ulcero-proliferative lesion may be observed, spontaneous bleeding
Alveolar/buccal mucositis score
Score	Description
0	Absence of lesion
1	Slight inflammation, no ulceration, no proliferation, no spontaneous bleeding, no bleeding induced by gentle pressure
2	Mild inflammation, no ulceration, no or slight proliferation, no spontaneous bleeding, no bleeding induced by gentle pressure
3	Moderate inflammation, ulcerative or ulcero-proliferative lesion may be observed, no spontaneous bleeding but bleeding induced by gentle pressure on the lesions
4	Severe inflammation, ulcerative or ulcero-proliferative lesion may be observed, spontaneous bleeding
Area of the caudal stomatitis lesions
The investigator will score the area of the inflammatory lesions on both sides, ie, the right and the left separately.
Score	Description *
0	No lesion area
1	Total area from 0 up to 0.5 cm2
2	Total area from 0.5 up to 1 cm2
3	Total area from 1 up to 2 cm2
4	Total area from 2 up to 3 cm2
5	Total area from 3 up to 4 cm2
6	Total area >4 cm2
