Abstract
|
|
|
This clinical study was performed for the purpose of investigating the effect of gingival index and simplified oral hygiene index of two dentifrices containing different abrasive agents. 40 dental collage students of age 2 "i-26 were divided 20 members of control group with using dentifrices containing colloidal silicone dioxide(SiO?), and others as experimental group with using dentifrices containing aluminum hydroxide(Al(OH)3) as abrasives. The gingival index and simplified oral hygiene index were analyzed before the experimental and the control dentifrices were supplied and there after 6 weeks.
The results were as follows
1. Mean SOW was reduced 20.7% by control group and 31.6% by experimental group stastistical difference was observed:
2. Mean GI was reduced 49.1% by control group and 55.0% by expenmental dentifrices group, but significant difference was not observed.
3. Significant difference in GI and SOW by tooth brushing method was not observed.
4. Factual knowledge about the abrasives, brushing method and pharmacy is scarce and further research on relevant topics seems to be indicated.
