A Randomised Control Trial For Evaluation Of Post-Operative Pain Following Application Of Resin Modified Glass Ionomer-based Varnish And Ormocer-based Varnish As A Treatment For Dentinal Hypersensitivity

Primary Hypothesis: There is a significant difference between the post-operative pain following application of Resin- modified Glass Ionomer-based Varnish And Ormocer-based Varnish as a treatment for Dentinal Hypersensitivity.

Null Hypothesis: There is no significant difference between the post-operative pain following application of Resin- modified Glass Ionomer-based Varnish And Ormocer-based Varnish as a treatment for Dentinal Hypersensitivity.

Double blinding will be done because the patient and the evaluator do not know the type of intervention being used. Then patients fulfilling the inclusion criteria will be recruited for this study. The treatment and the study design will be  explained to the qualifying patients, and informed consent will be obtained from the voluntary patients who were willing to participate in the study. Eleven patients with cervical defects  and having dentinal hypersensitivity reporting to OPD of Department of Conservative Dentistry and Endodontics under age group of 18-50 years will be selected for this study. Each selected patient had minimum two cavities in different  quadrants. A Visual Analog Scale(VAS) will be used to record the pre-operative sensitivity levels using air blast and cold test (ethyl chloride spray). Sequential randomisation will be done and patients were assigned into two experimental groups. (Group A:Resin- modified Glass Ionomer-based Varnish Group B: Ormocer-based Varnish).The application of varnish will be done according to manufacture’s instructions.The sensitivity score will be recorded using the pre-operative protocol immediately after application of experimental varnishes.The patient was recalled after 1 week and 1 month and similar protocol will be followed to evaluate postoperative dentinal hypersensitivity using VAS scale.
