Introduction and Objective: In the restoration of Devital teeth, the hopeful performance of fiber-supported materials, especially on break-resistance and polymerization thinning, has been demonstrated by various in vitro studies. However, the number of clinical studies published on this subject is quite small compared to the importance of the subject. The aim of this study is to investigate the clinical performance of composite resin restorations supported by short glass fiber. Method and Requirements: This study included 30 patients with channel-treated and temporary-filled small teeth. Half of the shortened glass fiber is restored with composite restorations, while the other half is only restored with nanohydrate resin composites. To evaluate clinical performance, the Modified USPHS (US Public Health Service) criteria were used 3 times by two restorative dental specialists in the initial, 6th month and 12th month check sessions. For statistical analysis of the difference between the scores, the Mc-Nemar test was used. The restorations showed small changes according to the criteria for marginal integrity, marginal coloring and anatomical shape, but these changes did not make a significant difference between the groups (p> 0.05). IN THE LIMITES OF THIS STUDY, all restorations, regardless of the fiber supplement, have been provided with sufficient aesthetics and function for a 12-month follow-up period.
