Comparative evaluation of trace elements and residual bacterial contents of different brands of bottled waters.
The present study was conducted to evaluate the comparative levels of cariostatic and caries potentiating trace elements and to detect residual coliform bacteria in six different bottled waters. Trace elements and fluoride were estimated using Inductively Coupled Plasma Optical Emission Spectrometer and fluoride ion electrode respectively. Coliform bacteria were detected by multiple tube method. It was found that, trace elements were below the significant caries potentiating or cariostatic levels and none of the samples showed coliform bacterial growth. It can be concluded from the present study that these water samples can be safely consumed without any dental ill effects.
