(1) −ve control = S. mutans in MHB; +ve control = Gentamicin (7.5 µg/ml MIC and 15 µg/ml MBC); Plant extract Shih (2.5 mg/ml MIC and 4 mg/ml MBC).
(2) Values are mean ± Standard error.
(3) Values in the same row and same time period bearing the same superscript do not differ significantly (P < 0.05).
