Evaluation of Post-Cementation Sensitivity After Cementation with Bio-Active Luting Cement - A Randomized Clinical Control Trial

Abstract

Background The most common complaint following cementation is the occurrence of post cementation sensitivity. The sensitivity to cold stimulus after cementation can be indicative of a gap present below the crown or a marginal gap connecting to opened tubules which emerge into the pulp. A pulp fluid outflow occurs as a result of the contraction of dentinal fluid in this gap which causes postoperative sensitivity. Thus luting agents should form complete seal between fabricated restoration and prepared tooth.Objectives The current study was conducted to clinically evaluate post-cementation hypersensitivity of bioactive luting cement in a randomized clinical control trial using resin modified glass ionomer cement RMGIC as the control.Methods According to standard tooth preparation protocol the teeth were prepared to receive Porcelain fused to metal PFM bridges on both sides of the mouth. PFM final restorations were cemented using Bioactive and RMGIC luting cement. Sensitivity was tested by using compressed airbiting pressure tests and cold water and was evaluated by using Schiff scale with 0-3 scores before cementation soon after cementation one week and three months post cementation.Results Almost all the patients responded to hypersensitivity at pre-cementation and baseline with compressed airbiting pressure tests and cold water. The sensitivity scores reduced over time one week and three months for both the luting agents.Conclusion Based on the results it can be concluded that the bioactive luting cement exhibited lesser sensitivity scores when compared to resin modified GIC luting cement.
