The qualitative assay with the 3-week biofilm on the canal portion
showed complete inhibition of bacterial growth when treated with Triphala,
MTAD, and NaOCl, but the samples treated with GTP and saline
showed the presence of bacterial growth. In quantitative analysis, GTPand
saline-treated tooth samples showed 1,516 17.2 CFU/mL and
156.4 109 3.1 109 CFU/mL (mean standard deviation),
respectively.
