Restoration of endodontically treated teeth has always been challenging for
clinicians, in particular in situations where there is not excessive loss of tooth
structure. A retrospective cohort study has recommended crown coverage for
the restoration of endodontically treated teeth1; however, the preparation of a
crown requires an additional significant loss of tooth structure. A clinical
pseudo-randomized trial on endodontically treated premolars with class II
cavities found no difference in restoration with composite and full-coverage
metal-ceramic crown at the end of 3-year follow-up.
There were more root fractures with the amalgam buildup
compared to the fiber post and composite buildup and more caries with the fiber
post and composite buildup than with the amalgam buildup.
