Comparison of Cyanoacrylate Glue and Fluoride Iontophoresis in the Treatment of Dentine Hypersensitivity

Aim: To evaluate and compare the efficacy of two treatment modalities Cyanoacrylate agent and Iontophoresis with acidulated phosphate gel (APF) application for dentinal hypersensitivity,. Materials and Methods: The subjects recruited in this randomized clinical study gave a history of tooth hypersensitivity and verified by light strokes with dental explorer. The patients were subjected to a tactile test, air blast and cold water stimuli and their responses were recorded on a verbal discomfort scale. A total of 40 sites were divided into Group A— Cyanoacrylate agent; and Group B—1.23% APF gel iontophoresis. The teeth were evaluated immediately after the treatment and at the end of 1 week. Results: The differences in the reduction in dentinal hypersensitivity in both the groups at 15 mins after the desensitization procedure and 1 week follow up were statistically non-significant suggesting that both the treatment modalities are equally effective for dentinal hypersensitivity. Conclusion:Both the treatment modalities were equally effective and can be effectively used for the treatment of dentinal hypersensitivity.
