Effect of Streptococcal IgY on Quantity of Streptococcus mutans in High Caries Risk Children

Abstract

Early childhood caries (ECC) is defined as a condition of one or more of decayed, missing, and filling in teeth (dmft) of children aging less than 71 months or even younger. Prevalence and severity of ECC is still high in some countries. Aim of this study to evaluate the effect of streptococcal IgY on the quantity of Streptococcus mutans in high caries risk children. 20 children aged 3-5 years were selected from the Department of Pedodontics of which 10 children were with high caries experience and 10 were controls who were caries free. Saliva swabs were taken from the occlusal surface of primary second molars and microbial count was counted using mitis salivarius bactaracinagar. High risk caries were given one No decayTM tablet morning and evening for 15 days. Swabs were taken before intervention and than 1 month, 2 months and 3 months post intervention. Streptococcus mutans count was significantly reduced in patients who have taken no decay tablets. Within the limits of the study, we found that streptococcal IgY was able to reduced streptococcus mutans count after 2 months. There was no statistically significant difference in Streptococcus mutans count between high caries risk children and caries free children after 3 months.
