Data was arranged in to 2 × 2 table and odd ratio was calculated for each symptom.

RESULTS

Odds ratio for dentine hypersensitivity, stomatitis, halitosis, heartburn, urticaria, papule and joint inflammation with 95% confidence interval were found 1.95 (0.97-3.93), 2.45 (1.12-5.40), 2.76 (0.96-7.98), 2.21 (1.09-4.53), 0.86 (0.32-2.32), 2.28 (1.02-5.05) and 4.85 (1.09-10.24) respectively.
