Embodiment 6
Under narcotism, select bacterial plaque scoring 2-4(bacterial plaque area dress computer more than 25% ~ 75% buccal side dental surface), gingivitis scoring at the slight or medium gingivitis of 1-3() beasle dog 12, be divided into experimental group and matched group at random, often organize 6.After Animal Anesthesia, to gingivitis and the calculus scores at its third molar place, with after dental plaque fluid colour developing, bacterial plaque is marked.
The gingival tissues simultaneously cutting 3mm in the vestibule region of the 3rd premolar teeth of its upper left side carries out HE dyeing, marks under light microscopic to inflammatory infiltrate.
The grading system of gingivitis is:
0: there is no gingivitis
1: very minimal gingival inflammation (red and swollen, to touch not hemorrhage),
2: minimal gingival inflammation (red and swollen, to touch delayed bleeding),
3: medium gingivitis (red and swollen, hemorrhage immediately after touching),
4: serious gum inflammation (ulcer, hematostaxis).
The grading system of dental calculus accounts for the area classification of buccal side dental surface according to dental calculus,
0:0%
1：＜25%，
2:25~49%，
3:50~74%，
4：＞75%。
Inflammatory infiltrate is marked:
0: what have the single or rickle of the chronic inflammation cell be dispersed in is arranged in surface epithelial cell,
1: have on epithelial side sparse but connect into band inflammatory cell assemble,
2: around epithelial cell, the inflammatory cell of a large amount of infiltration instead of normal gingival fiber,
3: extensive in the tissue, a large amount of inflammatory cell assembled instead of most gingival fiber.
Then respectively with infiltrating the tooth and the gums that have the cotton balls for the treatment of gingivitis medicine in embodiment 5 to cover animal lip side and area ace, normal saline contrasts, each 10 seconds, twice daily, continues 14 days.Within 15th day, again by Animal Anesthesia, and to its bacterial plaque, gingivitis and calculus scores, the gingival tissues simultaneously cutting 3mm in the vestibule region of the 3rd premolar teeth of its upper right side carries out HE dyeing, marks under light microscopic to inflammatory infiltrate.
Result shows that bacterial plaque and gingivitis symptom score significantly reduce at experimental group, p < 0.05, and matched group is without significant difference, and p > 0.1, concrete outcome is in table 3 after treatment.
