Dental erosion protection by fermented shrimp paste in acidic food.

Caries Research 44(1):20 (2010) PMID 20068304

The aim of this study was to determine the extent to which fermented shrimp paste (which has a high calcium concentration) reduces dental erosion in vitro. In experiment 1, enamel specimens were exposed to various concentrations of shrimp paste in tamarind juice for 15 min, once a day, for a total of 29 days. In experiment 2, pre-softened enamel specimens were exposed to different concentrations of shrimp paste in water, using an exposure method similar to experiment 1. Profilometry and a microhardness test were used to assess changes in enamel loss and softening. The results showed that shrimp paste can reduce the erosive potential of tamarind juice and re-harden softened enamel. Copyright 2009 S. Karger AG, Basel.
