Aim: The aim of this study is to comparatively evaluate the topical application and iontophoresis of 8% proarginine for the treatment of dentinal hypersensitivity
The objectives of the study are
1. To evaluate the efficacy of a desensitizing toothpaste containing 8% proarginine for hypersensitive dentin
2. To evaluate the efficacy of iontophoresis with a desensitizing toothpaste containing arginine (Colgate sensitive pro-relief)
3. To compare the efficacy of the above methods.
Material and method: Two groups of 40 patients each having dentinal hypersensitivity were treated using 8% proarginine and iontophoresis. The patients were recalled after 1 week, 2 weeks and 4 weeks. The scores were tabulated and the results were analyzed using SPSS statistical software.
Result: While comparing the visual analog scale between the two groups we could see that there was significant difference at 1st week till 4th week. But when we compare immediately after treatment 12.5 % of people are in the score 3 in Iontophoresis group, whereas only 5% in the Proarginine group. But the difference is not found to be significant. At the time of 4 weeks we could see the difference between two groups in which nearly 52.5% of people are having the score of 1 in Proarginine where as in Iontophoresis group nearly 77.5 % of people are having score 1 and this is found to be very highly statistically significant .(P<0.001)
Conclusion: Iontophoresis when used along with Colgate sensitive pro relief toothpaste can provide additional benefit when we treat severe cases of dentinal hypersensitivity when used for a longer period of time.
