Cariogenicity of Vitamin Supplements for Children / 대한소아치과학회지

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.

Study on the ability of acidogenicity and aciduricity of Streptococcus mutans isolated from children with different caries susceptibility / 实用口腔医学杂志

Objective: To investigate the acidogenicity and aciduric ability of Streptococcus mutans isolated from the children with different caries susceptibility.Methods: The acidogenic and aciduric ability of Streptococcus mutans strains isolated from children was investigated.Acidogenicity ability was compared among high caries-susceptible group,middle caries-susceptible group and caries-free group.Results: The acidogenicity and aciduric ability of Streptococcus mutans isolated from the high caries-susceptible children and middle caries-susceptible group were significantly higher than that isolated from caries-free group(P
