Abstract
결 론
우유, 모유, 시판 가당 두유의 치아 법랑질 탈회력을 생체외에서 영구치 시편을 이용하여
비교 연구하였다. 우유, 모유, 두유 및 각 원유에 타액과 자당을 혼합한 용액에
Streptococcus sobrinus와 우식 상아질에서 채취한 내산성 산 생성균의 배양액을 접종하고
표면을 고도로 연마한 영구치 법랑질 시편을 넣은 다음 37℃에서 25시간 배양하였고, 배양
전후의 실험용액의 pH와 영구치 법랑질 시편의 표면 미소경도의 차이를 측정하여 산 생성
과 탈회의 양을 평가하여 다음의 결론을 얻었다.
1. 두유가 우유및 모유보다 탈회력이 더 컸다 (p<0.01).
2. 모유가 우유보다 탈회력이 약간 더 큰 경향이 있었으나 그 차이가 유의하지는 않았다
(P>0.05).
3. 자당의 첨가는 우유와 모유의 탈회력을 증가시켰고 두유에서는 감소시켰다.
#초록#
The purpose of this study was to compare the tooth enamel demineralizing potential of
bovine milk, human milk, and soy milk in vitro. Sucrose and saliva were added to each
kind of milk separately or together. Therefore, there were twelve experimental solutions
in total. Tooth enamel specimens which were cut from extracted permanent teeth were
embedded in the resin blocks and polished. The surface microhardness of specimens was
measured by the microhardness tester, and the specimens which have the surface
microhardness from 300 VHN to 370 VHN selected for the study.
Streptococcus sobrinus and the bacteria which were sampled from the caries dentin
were inoculated to the experimental solutions and the solutions were incubated at 37℃
for 24 hours. After the incubation the surface hardness was measured again, and the
difference between before and after incubation was regarded as demineralizing potential.
The obtained results were as follows :
1. The demineralizing potential of the soy milk was greater than that of the bovine
milk or of the human milk (P<0.01).
2. The demineralizing potential of the human milk was slightly greater than that of the
bovine milk but the difference was not significant.
3. Sucrose increased the demineralizing potential of the bovine milk and the human
milk but decreased that of the soy milk.
4. Among the all experimental solutions, the soy milk with no sucrose or saliva
showed the highest demineralizing potential, and the soy milk with surose and saliva
showed the highest acid production.
5. Among the all experimental solutions, the bovine milk with no sucrose or saliva
showed the lowest demineralizing potential and acid production.
