Abstract :

Aims: To compare the caries experience and 2D:4D ratio of 14-16 year old school going students in Davangere city with different genetic sensitivity to bitter taste of 6-n propylthiouracil.

Methods and Material: A cross sectional survey was conducted among 350 school children aged 14-16 years. 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. The categorical data was compared using Chi square test.

Results: 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).

Conclusions: Majority of tasters were caries free compared to non-tasters. There was no significant association between taste sensitivity and 2D:4D ratio and caries experience and 2D:4D ratio.
