1. In case of bad breath
A) Caused by oral origin
There are several causes of bad breath. In my clinical experience, 90% of bad breath is caused by dental caries or gingivitis. In this situation, a substantial effect can be achieved by appropriate brushing for 1 week to 1 month after caries treatment and scaling.

B) Endocrine disturbance
In adolescence, there are some cases causing intolerable bad breath. After that period it becomes less, but in case of using the two stripe toothpaste for 15 days it will lessen and disappear completely after 1 month use.

C) Empyema or other disease
If there is a continuation of bad breath after over 1 month using the two stripe toothpaste with appropriate brushing, you should consult ENT doctor first.
2. In case of redness of gum and easily bleeding
It is the result of the reaction for bacterial infection. A substantial effect can be achieved by appropriate brushing for 1 week to 1 month after caries treatment and scaling. There is frequent redness in the gingival after delivery of prosthetics. The two stripe toothpaste will relieve the symptoms.
3. Frequent ulcer development
Regular use of the two stripe toothpaste can prevent development of stomatitis. Even when it is developed, one or two minute application of the toothpaste on the site and brushing would relieve pain, maintain the size and disappear within 1-2 weeks.
4. Swollen tonsil at the turning of seasons
It was informed by the patient who used the two stripe toothpaste regularly that easily swollen tonsils do not get swollen. It could be help to th0e patients with same symptoms.
£µ. When mucogingival surgery needed after scaling
In my clinical experience, I could find some cases as followed. When gingival inflammation is severe, it is recommended that scaling and gingival incision to remove deeper inflammation. After scaling and regular use of the two stripe toothpaste usually lessen the symptoms. Therefore, patients do not have to fear the operation, pain, and extra expense.
6. To someone who has Intestinal trouble and does not go well with beer or milk
Some patients who used the two stripe toothpaste said their stomachache due to the diarrhea after the consumption of milk or beer. We could notice this effect by the patients who used the two stripe toothpaste regularly. It leaded us to perform a study on lactobacillus. The result of the experiment told us that lactobacillus grows five hundred times more after 14 hour culture.
