OBJECTIVE
To investigate the effect of cast post-core porcelain fused to metal crown on the restoration of residual root and crown of molars.


METHODS
One hundred and sixty-four residual roots and crowns of molars were treated with root canal therapy and restored by cast core porcelain fused to metal crown. The restoration effect was assessed at the 3rd, 6th, 12th and 24th month.


RESULTS
The strength of dental prosthesis retention, marginal fitness, and strength of crowns were satisfactory. The effective rate reached 95.12% during the 2 year follow-up.
