Effects of soybean milk, chitosan, and anti-Streptococcus mutans IgY in malnourished rats' dental biofilm and the IgY persistency in saliva.

Objective: This study aims to evaluate the eff ect of soybean milk containing a combination of anti-Streptococcus mutans IgY and chitosan to the colonization of S. mutans in the saliva and to the IgY persistency in the saliva.

Materials And Methods: Experimental malnourished Sprague-Dawley rats were fed with soybean milk that is enriched with anti-S.
