Based on PROP test children were categorized into tasters and non-tasters. Caries experience and 2D:4D ratio of left hand were recorded using Decayed Filled Missing teeth (DMFT) index and Vernier Calipers respectively. <span style="color:black">The categorical data was compared using Chi square test.</span><o:p></o:p></span></p> <p class="MsoNormal" style="text-align:justify;line-height:200%"><b style="mso-bidi-font-weight:normal"><span lang="EN-GB" style="color:black">Results:</span></b><span lang="EN-GB" style="color:black"> </span><span lang="EN-GB">The percentage of caries free children (DMFT=0) was significantly higher (p=0.017) among tasters (58.8%) compared to non-tasters (44.6%). There was no significant association between taste sensitivity and 2D:4D ratio (p=0.98) and caries experience and 2D:4D ratio (p=0.84).<b style="mso-bidi-font-weight:normal"> <o:p></o:p></b></span></p> <p class="MsoNormal" style="text-align:justify;line-height:200%"><b style="mso-bidi-font-weight:normal"><span lang="EN-GB" style="color:black">Conclusions: </span></b><span lang="EN-GB">Majority of tasters were caries free compared to non-tasters.
