Summary

Background: A real challenge faces practitioners in dealing with permanent molars in young patients starting from proper selection of endodontic treatment system till the type of final coronal restoration. For permanent molars in young age patients, which system should be followed to guarantee better performance and enhance the integrity of such weakened teeth? The question most commonly asked. Purpose: To evaluate two-year clinical performance of endocrowns as permanent restorations for endodontically treated molars in young age.

Detailed description

Endodontic treatment will be done for all patients using ProTaper Next rotary files and iRoot SP sealer. Then patients were randomly divided into two groups; Gr 1: Conventional group (CG), the coronal cavity will be restored directly with bulk-fill nanohybrid composite restorations. Gr 2: Endocrown group (EG), the coronal cavity will be restored with IPS e.max CAD endocrown restorations. * First step: Endodontic treatment protocol will be used as the following: 1. Biomechanical preparation using; 2.6% NaOCl for irrigation, ProTaper Next rotary files for instrumentation and 17% EDTA gel for lubrication. 2. Obturation of root canal using; ProTaper gutta-percha and iRoot SP sealer. * Second step: Endocrown restoration protocol will be used as the following: 1. Occlusal Butt joint design for Endocrown preparation. 2. Putty-wash technique for taking impression. 3. IPS e.max CAD for Endocrown construction. 4. G-CEM self-adhesive resin cement for Endocrown cementation. * Follow up visits: The patients will be recalled every 6 months for evaluation. * Evaluation methods: * Endodontic treatment evaluation: The outcome will be evaluated clinically and radiographically. * Endocrown restoration evaluation: The outcome will be evaluated clinically in terms of; marginal adaptation, marginal discoloration and surface alteration.
