OBJECTIVE To determine and correlate the effect of clomiphene citrate, Letrozole in women undergoing infertility treatment on the gingival inflammatory status. METHODS The present study is a randomized controlled clinical trial which consisted of 26 women using CC for three menstrual cycles, 26 women using CC for more than three cycles, 26 women using Letrozole. All subjects were clinically examined for plaque levels (Plaque Index), gingival inflammation, bleeding on probing (Gingival Index, Sulcus Bleeding Index). Scaling was done to all patients and all periodontal parameters were reassessed 1 month after scaling. The results were compared with a control group of 26 women matched for age, educational status and professional level, and oral habits and who had never used ovulation drugs. RESULTS Baseline scores of all the test groups showed higher amount of plaque levels and inflammation compared to control. (p < 0.05). After scaling a significant reduction in inflammation was observed in all the test groups along with the control group (p < 0.0001), but women using the drugs showed persistence of inflammation compared to control (p < 0.01). CONCLUSIONS It can be concluded from the present study that the presence of elevated levels of hormones due to the effect of ovulation induction drugs may be the reason for the gingival inflammation in test groups.
