Case Report: Split To Strengthen: Modified Cast Post To Rehabilitate The Multirooted Teeth

Abstract

The replacement of missing tooth structure and rehabilitate the destructed part of teeth has been practiced by various cultures for thousands of years. Restoring grossly decayed teeth are always challenging for endodontist, especially in case of multi rooted teeth with or without divergent roots. A tooth with extensive coronal destruction due to carious process, sometime poses difficulty in fabrication of FDP, The post core is often required to gain support from the remaining tooth structure. In a multirooted tooth where more then one root were used as support the path of insertion of post is difficult, those cases can be saved by using split cast post and core. Endodontically treated tooth with total loss of coronal tooth structure and loss of cavity walls, multiple posts in both the roots appear necessary so as to achieve proper retention for the core material. This is a simple and scientific multidisciplinary approach towards management of grossly decayed tooth. Cast post and cores have many advantages, especially the retention and resistance they provide and strength to already weakened tooth structure. Cast post with cores should not bind within the root canal. This technique has been used for a long time and with positive results recognized by many authors. In this clinical case report restoration of an root canal treated carious mandibular first molar, directly restored and rehabilitated with split-cast post and core.
