Abstract

An in vitro study on cariogenic potential of four over-the-counter nutritional supplements for children was performed. The experimental groups were four over-the-counter nutritional supplements. The positive control group was 10% sucrose solution (S), and the negative control group was artificial saliva (T). The pH of each group, the buffering capacities, acid production, the microhardness changes of the bovine teeth specimens were measured. The pH of all experimental groups were lower than critical pH 5.5 where enamel demineralization starts. The buffering capacity of the Hama Vitamin Pharm (Hamsoa Pharm Co., Korea) was highest, and the Smart Chewable Vitamin A (JW Pharm Co., Korea) had the lowest buffering capacity. The reduction rates of the pH of the experimental groups were significantly higher than that of the negative control group (p < 0.05). The microhardness of enamel of all experimental groups and the positive control group significantly decreased. In contrast, the microhardness of enamel of the negative control group significantly increased after experiment (p < 0.05). The reduction rate of the microhardness of enamel of the Hama Vitamin Pharm (Hamsoa Pharm Co., Korea) was significantly higher and Hikid Plus (Sanga Pharm Co., Korea) was significantly lower than the other experimental groups.

어린이용 영양제의 우식 유발능에 관해 알아보기 위하여 국내에서 시판 중인 건강기능식품 어린이용 영양제 4종에 대한 생체외 연구를 시행하였다. 어린이용 영양제 4종을 실험군으로, 10% 자당을 양성 대조군, 인공 타액을 음성 대조군으로 하였다. 실험군 및 대조군의 pH, 완충능, 산생성능, 우치 법랑질 침식능을 검사하였다. 실험군 4종의 pH 모두 탈회 임계 pH인 5.5보다 낮았다. 완충능은 Hama Vitamin Pharm이 가장 크고, Smart Chewable Vitamin A가 가장 작았다. 4개의 실험군은 음성 대조군보다 유의하게 높은 산생성능을 보였다(p < 0.05). 우치 법랑질 침식능 검사 결과, 4종의 실험군과 양성 대조군에서 표면미세경도가 유의하게 감소하였다(p < 0.05). 표면미세경도 감소율은 실험군 중에서 Hama Vitamin Pharm이 유의하게 높았고, Hikid Plus는 유의하게 낮았다(p < 0.05).
