ABSTRACT

Introduction Patients frequently complain about the sensitivity of the teeth after teeth preparation of the abutment teeth for the fabrication of a fixed prosthesis. This sensitivity is generally observed during the temporization period and after the final cementation of the full coverage restorations. This sensitivity can be reduced by using desensitizing agents. These de sensitizing agents are not easily available and are expensive. The aim of this study was to evaluate the effectiveness of a commercially available inexpensive material based on Casein phosphopeptide–amorphous calcium phosphate (CPP-ACP) varnish on reduction of sensitivity following tooth preparation. Materials and method This prospective study consisted of 15 patients who had missing teeth and desired replacement with fixed partial dentures. CPP-ACP Varnish (Mi Varnish, GC, Japan) was applied over the prepared tooth surfaces using an applicator brush. Patient evaluation was done immediately after tooth preparation and after a 3 day follow up. At both these appointments a 10 point VAS score was provided and the participants indicated their levels of sensitivity on the scale. The VAS score data was statistically analyzed using the Wilcoxon Signed ranks test in IBM SPSS software version 20. Results The MI varnish application post tooth preparation resulted in a statistically significant (p<0.05) reduction in the sensitivity following immediate application of the varnish after tooth preparation. There was no significant difference observed in the reduction of sensitivity after a 3 day follow-up. Conclusion Application of MI varnish following tooth preparation is recommended to manage postpreparation sensitivity.
