蔗糖を含む Soft Food による実験的歯肉炎

カニクイザルでの観察

抄録

It has been reported that the physical character of the diet influences on the periodontium, and soft food has a tendency to cause gingivitis more than hard food. On the other hand, sucrose has an important role for plaque formation, and so it seems logical to consider that sucrose may also have an influence to cause gingivitis, but very few study has performed to clarify the relationship betwees sucrose and gingivitis.
The aim of the present study was to investigate the effect of the soft food containing sucrose on the gingiva and to establish an experimental method to cause gingivitis quickly with food control.
One adult male Macaca irus monkey was used and the schedule of this experiment was as follows:
1. Preliminaly period (12 days, Hard food, Scaling and Brushing on every 2 days)
2. Control period (30 days, Soft food without sucrose)
3. Preliminaly period (12 days, Hard food, Scaling and Brushing on every 2 days)
4. Experimental period (30 days, Soft food with 20% sucrose)
The result of this study indicated that the gingival inflammation during the experimental period was developed more severly and more fast than that of the control period.
