All about Dowels - A Review Part I. Considerations before Cementation
Journal Title: Journal of Clinical and Diagnostic Research - Year 2017, Vol 11, Issue 8
Abstract
The optimal way of restoring a non vital tooth with dowel-core technique has long been a controversial matter. The purpose of this review was to assess the factors that may influence the successful restoration of root filled teeth with root canal dowels. The first part of the review discusses indications and physical parameters of dowel. Searches were performed in PubMed/Medline database using single or combined key words to obtain the most relevant list of references. Articles selected in the search process were obtained from the journals and reviewed with every aspect of dowel system for reconstruction of endodontically treated teeth. Medline search showed 228 articles for dowels but after applying exclusion criteria, only 51 articles remained to be included in Part I of this review. Out of which, 49 were in vitro studies and two were clinical studies. Reviewing the literature revealed that clinical data is still missing. Literature emphasizes that dowels should only be used for the retention of core material and not in view of reinforcing the remaining tooth structure. The dowel length is limited by the apical seal of four mm to six mm. Dowel width should be as small as possible. Canal configuration determines the selection between prefabricated and custom cast dowel. Fiber based dowel may be clinically appropriate for restoration of endodontically treated anterior tooth, although clinical studies are lacking.
