Clinical comparison of postoperative sensitivity for an adhesive resin cement containing 4-META and a conventional glass-lonomer cement.

摘要: Purpose The aim of this clinical 2-year follow-up study was to compare the postoperative sensitivity abutment teeth restored with full coverage restorations retained either conventional glass-ionomer cement or a new adhesive resin containing 4-methacrylolyloxyethyl trimellitate anhydride (4-META). Materials and methods Sixty patients received 120 full-coverage on vital teeth, cemented (Ketac-Cem) (Chemiace II). A randomized split-mouth design patient double-blind data acquisition protocol were used. examined before cementation, after 1 week, 6, 12, 24 months. Results With regard postcementation sensitivity, low incidence observed for both groups. cement, little hypersensitivity week (13.3%), 6 months (5.9%), 12 (2.1%), (none); results similar Ketac-Cem (6.4%), (none). After months, 2 Chemiace II group showed no sensitivity. Endodontic treatment carried out these teeth. cases recorded group. Conclusion In study, cementation full-crown similar.
