Six Months Evaluation of Post-Operative Sensitivity in IFPDs

Objectives:This prospective clinical trial evaluated the post-operative sensitivity in inlay fixed partial dentures (IFPDs) using two different adhesive bonding systems and provided 6 months results. Methods:Twenty-three inlay bridges made with Adoro-Vectris (Ivoclar-Vivadent) were placed in 23 patients (ages 19-50) and evaluated using the US Public Health Service criteria. Eleven restorations were luted with Syntac Classic (Ivoclar-Vivadent) and the others with Excite DSC (Ivoclar-Vivadent) and randomly cemented with Variolink II or Tetric Ceram and ultrasonic system. Restorations were evaluated in six categories (color match, marginal adaptation, secondary caries, anatomic form, marginal discoloration, postoperative sensitivity) and as the percentage receiving Alfa (ideal), Bravo (clinically acceptable), Charlie (clinically unacceptable) scores. Results: All restorations received score of Alfa at the following rates: color match, 97%; marginal discoloration, 100%; secondary caries, 100%; anatomic form, 100%; marginal integrity, 100%; postoperative sensitivity, 70%. Except for the post-operative, statistical analysis (McNemar test) indicated no significant differences in any categories at baseline and after 6 months. IFPDs luted with Excite DSC showed 58% of post-operative sensitivity while Syntac Classic 0%. Significant difference (P<0.05) was observed between the two bonding systems. Conclusion: After 6 months in vivo IFPDs luted with 3 steps bonding system showed better clinical service than 2 steps. monacocarl@libero.it
