Abstract:
Objective To compare the clinical results of endodontic mandibular first molar by different restoration methods.Methods From January 2011 to February 2013,96 patients in our hospital dental visits with 110 defective teeth who accepted the dental restoration were randomly selected in this clinical research.The repairing of defective teeth were divided into 3 groups randomly:36 were fabricated with CAD/CAM zirconia all -ceramic crowns,35 were CAD/CAMzirconia all -ceramic onlays,39 were direct filling and repairing with composite resins. The clinical effects of 3 groups were evaluated and compared at baseline,and 1,6,12 months after restoration using modified USPHS criteria.The results were analyzed statistically by SPSS 13.0.Results It was not found that 110 defective teeth were debonded at 12 months after restoration.There were significant differences in assessment results of secondary caries,marginal fitness,appearance and color matching at 12 months after restoration by different restoration methods (χ2 =6.705,7.768,6.910,11.624,all P <0.05).Conclusion The dental restorations with CAD/CAMzirconia all -ceramic crowns and CAD/CAM zirconia all -ceramic onlays show satisfactory clinical performance in short time.
