Statement of the problem For permanent molars in young age, which treatment planning guarantees better performance of such weakened teeth should be followed starting from the endodontic therapy till the final coronal restoration? Purpose The aim was to evaluate the performance of endocrowns as permanent restorations for endodontically treated molars (ETMs) in young age in a 2-year period. Materials and methods Inclusion and exclusion criteria were established. Ten patients of 9–12 years old were selected at random, in accordance with Research Ethics Committee (REC) of Faculty of Dental Medicine for Girls, Al-Azhar University and in conjunction with Departments of Pedodontics, Endodontics, and Crowns and Bridges. For endodontic treatment, Protaper Next system and iRoot SP sealer were used. According to the coronal restoration type, the patients were divided into two groups. Group 1: the patient received direct composite resin restorations, and Group 2: the patient received endocrown restorations. Due to the small sample size, statistical descriptive methods were applied. Results After 2-year follow up, all endocrowns were in function while two composite restorations failed. Conclusions In young age, ETMs restored with Protaper Next system, iRoot SP sealer, and IPS e.max CAD endocrowns have excellent clinical performance. Clinical significance In young age, whenever indicated, endocrowns are highly recommended for ETMs as permanent, esthetic and conservative type of restorations.
