XP Bond in Self-Cure Mode Used for Luting Porcelain Restorations: 4-year Recall

Abstract

ABSTRACT Purpose The aim of this clinical study was to evaluate some clinical parameters of Empress II restorations luted under clinical conditions with XP Bond in combination with SCA and Calibra cured in self-cure mode after 4 years of clinical service. Materials and methods Fifty-three restorations were placed in 38 patients from March 2006 until April 2006. No patient received more than two restorations. Luting procedures were performed following manufacturers’ instructions. The restorations were evaluated for postoperative sensitivity, marginal discoloration, marginal integrity, secondary caries, maintenance of interproximal contact and fracture at baseline, after 2 weeks, 6 months, 1, 2, 3 and 4 years of clinical service. Results At the 4-year recall 49 restorations were reevaluated. The clinical examination showed that postoperative sensitivity did not affect any restoration. Only 5 restorations of 49 showed bravo score and 2 charlie for marginal integrity/stain.1 restoration showed bravo score at vitality test and another restoration for interproximal contact. Secondary caries, retention and fracture parameters showed alpha scores. Conclusion All the evaluated restorations were in place and acceptable. The postoperative sensitivity recorded after using XP BOND with SCA and Calibra in self-cure mode was clinically acceptable after 4 years of clinical service and no serious endodontic complications were recorded.
