Galla chinensis Compounds Remineralize Enamel Caries Lesions in a Rat Model.

Objectives: To investigate the effect of Galla chinensis chemical compounds on enamel caries remineralization in rats.

Methods: A total of 40 rats were inoculated with Streptococcus sobrinus 6715 and fed a cariogenic diet (Keyes 2000). The rats were randomly divided into 4 groups and treated topically twice a day with each of the following extracts (or control) for 5 weeks: distilled and deionized water (DDW, negative control); 1,000 ppm NaF (positive control); 4,000 ppm G.

[The effect of coaggregation of A.viscosus and P.gingivalis on the adherence of A.viscosus to hydroxyapatite].

Purpose: To examine the effect of coaggregation of A.viscosus and P.gingivalis on the adherence of A.

[Effect of chemical compounds of Galla chinensis on enamel surface rehardening in vitro].

Objective: To evaluate the effect of chemical compounds extracted from Galla chinensis on enamel surface rehardening in vitro.

Methods: Sixty bovine enamel blocks with early carious lesions were randomly divided into six groups: group1 treated NaF (positive control); group2 with GCE; group3 with GCE-B; group4 with GCE-B1; group5 with GCE-B2 and group6 with deionized water (negative control). The lesions were subjected to a pH-cycling regime for 12 days.
