Background: Dentinal hypersensitivity is an exaggerated response to non noxious stimuli such as thermal, chemical, evaporative and tactile. Pain is characterized by short sharp pain from exposed dentinal tubules. There are various treatment modalities available such as conventional methods like iontophoresis, desensitizing agents in the form dentifrices, dental varnishes, bonding agents and nowadays concept of laser therapy is being popularized.
Materials and Methods: In the present study, 90 sites were divided into three groups as group1 (Iontophoresis with NaF), group 2 (Low level laser therapy) and group 3 (control group- saline solution). Pain scores were measured by Visual analogue scale given by Plagmann et al in 1997 by air blast method, tactile examination and cold water test at baseline and at 14th day.
Results: After intragroup and intergroup analysis, it has been shown that iontophoresis and LLLT has shown reduction in VAS scores from baseline to 14th day postoperatively but at the same time iontophoresis has shown comparatively more reduction in VAS scores than LLLT group and control group.
Conclusion: Fluoride iontophoresis can be used as a first line treatment, before other therapeutic steps like resin primers and low level laser treatment are considered for the treatment of dentine hypersensitivity.
