**29. Conclusion**

The rational for the post placement is two folds that is,

1.To retain the restoration, and.

2.To protect the remaining tooth structure.

The success rate will be high if the rationales for the results are understood, appreciated and propagated accordingly. A technique with more advantages and fewer disadvantages in the given restoration should be chosen. It is important to preserve as much tooth structure as possible, particularly in the root canal. The post should be adequate length for good stress distribution but not as long as to jeopardize the apical seal. In the final analysis the quality of the root canal thereby combined with the quality of its final restoration determines the clinical success of pulpless tooth with post and core.
