Background: In dentistry, Thyme oil is studied in researches for its effectiveness in dental caries and dental plaque. Efficacy of Thyme oil was investigated in dentinal hypersensitivity (DH) based on the proposed role of essential oils in hypersensitivity.

Aim: It was to compare effectiveness of Thyme oil with a desensitizing tooth paste in DH.

Methods: Each group included 20 patients with DH. Group I was given Desensitizing Tooth Paste and Group II were advised to apply Thyme Oil. Patients with two or more sensitive teeth and in good general health were included. Fractured restorations, pregnancy, lactation, allergy to thyme and patients with bleeding disorders were excluded. A Visual Analogue Scale of 10 cm in length was used to assess sensitivity scores for response to cold air (using a dental air syringe) at baseline and 8th week post-treatment.

Statistical Test: Wilcoxon signed rank test was applied at 95% CI for intra group comparison and Mann-Whitney test for inter group comparison.

Results: Oil group was shown to have significant reduction of moderate pain /hypersensitivity in post treatment when compared with post treatment VAS scores of Paste group. There was no correlation between teeth related variable and intervention outcome in two study groups.

Conclusion: Studies with increased sample size with varying time periods need to be carried out to establish the efficacy. Toxicological assessments are often deficient for traditional medicines. Further clinical trials are obligatory to exclude the possibility of side effect. If used properly, they may prove very beneficial in dental treatment.
