[0017]
[Table 1]
Figure 0004944309
[0018]
Effect on periodontal disease 0.5 g of the periodontal disease preventive and therapeutic agent shown in Table 1 was applied to the gums of five men with periodontal disease every morning and evening. The state of gums was diagnosed by palpation and visual inspection and indexed according to the following evaluation criteria.
Evaluation criteria 0: No inflammation 1: Mild inflammation-slight changes in gingival color and surface morphology 2: Moderate inflammation-moderate gingival surface gloss, redness, edema and swelling. Hemorrhage due to compression 3: Severe inflammation-prominent redness and swelling, tendency of sudden bleeding, and average ulcer score 6 representative teeth of the oral cavity (upper left first molar, left incisor, right first premolar, And the lower left first premolar, right incisor, right first premolar of the lower jaw), and diagnose a total of 24 sites per tooth (buccal, lingual, mesial, distal), The average value of all five evaluation points was used as an index of the effect on periodontal disease.
[0019]
Table 1 shows the average evaluation points. All of the products of the present invention recognized a remarkable periodontal disease improving effect in a short period of time. Further, in the product 1 of the present invention, 15 sites where inflammation with a score of 2 or more was observed before the start of the test were all improved to a score of 1 or less on the 7th day from the start of application. Also, the same 14 and 15 sites were all improved to a score of 1 or less on the 7th day, and thus a remarkable periodontal disease improving effect was recognized particularly for moderate and severe inflammation.
[0020]
Example 2
A gum massage cream having the following composition was produced.
Cedrol 0.2% by weight
Gelled hydrocarbon 56
Glycerin 20
Sucrose fatty acid ester 5
Fragrance 0.7
Saccharin sodium 0.1
This gum massage cream had a remarkable periodontal disease improving effect.
[0021]
【Effect of the invention】
The preventive / therapeutic agent for periodontal disease of the present invention can reduce and improve the periodontal disease in a short period of time, and is excellent in the effect of preventing and treating periodontal disease. Moreover, the oral composition containing it is also excellent in the periodontal disease prevention effect.
