초록
본 연구의 목적은 어린이들이 섭취하는 비타민 제제들의 우식원성을 치아우식 유발지수와 Streptococcus mutans 의 활성정도 및 산생성능을 통해 분석하는 것이다. 4가지 비타민, 노마(NM), 세노비스 키즈(CK), 애니멀 퍼레이드(AP), 캐릭터 비타민(CV)를 대상으로 진행하였다. 치아우식 유발지수를 산출한 결과 AP, CV, CK, NM 순으로 작아졌다. pH 측정 시 모든 실험군들의 초기 값은 산성을 나타내었다. S. mutans 의 군집 형성 단위를 분석한 결과 NM, CV은 대조군에 비해 더 높은 증식률을 보였고(p < 0.05), CK와 AP (p < 0.05)는 대조군에비해 더 낮은 증식률을 보였다. 공초점 현미경으로 관찰하였을 때 실험군들은 대조군에 비해 높은 세균 활성도를 보였다. 비타민 제제들의 세균 활성도와 산도를 고려해 볼 때, 어린이의 구강 건강을 위해서는 세심하게 고려하여 섭취해야 할 것이다.
Abstract
The purpose of this study is to analyze the cariogenicity of vitamin supplements for children by the Caries Potentiality Index (CPI), pH drop capacity, proliferation rate of Streptococcus mutans . Four vitamin supplements were selected - Noma (NM), Cenovis Kids (CK), Animal Parade (AP), and Character Vitamin (CV). CPI value decreased in the order of AP, CV, CK, and NM. Initial values of all experimental groups showed acidity below pH 7.0. Analysis of the colony forming units of Streptococcus mutans showed that NM and CV resulted a higher proliferation rate (p < 0.05) than CK and AP (p < 0.05). Bacterial activity of the control group was lower than other groups when observed with a confocal laser scanning microscope. Considering the bacterial activity and acidity of vitamin supplements, it is necessary to pay close attention when children taken the vitamin supplements for their oral health.
