다국어 초록 (Multilingual Abstract)

Two-part experiment was conducted to elucidate the effects of several trace elements, rice and spices on caries rate in Korean albino rats. Rats were selected into two large groups according to their weight ; one group (for part I experiment) consists of rats weighing 140-200gm and the other group (for part II experiment) consists of rats weighing 76-109gm, and the same experiment was conducted independently for both groups. Rats were fed standard cariogenic diet supplemented with rice (21, 53%), capsicum (1, 10%), garlic (0.5, 5 or 10%), phosphorus (2%), sodium chloride (3%, reagent grade), or table salt. Drinking water was tap water containing cold water extract of capsicum (0.1%) alcoholic extract of capsicum (0.1%), water extract of ginseng (2%), fluoride (10, 50 or 100ppm) or 50ppm of Mg, Zn, Mo, Sr, Mn of Fe. The results were as follows.
1. 24.9%, 51.0% and 54.3% decrease in caries score were recorded for rats which drank water containing 10, 50 and 100ppm of fluoride in part I experiment. In part II experiment caries score decreases 51.8% and 56.9% for 10ppm and 50ppm fluoride content.
2. Capsicum-fed rats showed 51.7% (capsicum 1%) and 58.1% (capsicum 10%) decrease in caries score in part I experiment. 21.5% and 33.6% decrcase were recorded for part II experiment.
3. Garlic-fed rats showed 44.5% (garlic 0.5%), 23.0% (garlic 5%) and 53.7% (garlic 10%) decrease in caries score.
4. Sodium chloride-fed rats showed 122.6% (NaCl 3%) increase in caries score.
5. Rats which were fed diet containing 2% Na_2HPO_4 showed 26.7% decrease in caries score and further 41.6% decrease when 10ppm fluoride was given simultaneously.
6. 28.4% and 31.5% decrease in caries score were recorded for rats which drank water containing 50ppm of Mg and Zn.
