<p><strong>Background</strong>: Cuspal fractures are more concentrated in maxillary premolars after root canal treatment. It has narrower mesiodistal dimension leading to longitudinal root fractures. To cut down multiple visits and burgeoning&nbsp; crown expenditures, prevent mishaps of using posts in narrow roots, microleakage and bacterial contamination with temporary restorations, this study uses adhesive procedures which intend to save maximum tooth structure with fiber reinforcement in composite core for its increased durability, esthetics, and damage tolerance as permanent restoration. <strong>Materials and Method</strong>: Forty extracted maxillary first premolars were randomly divided into four experimental groups (n=10) : Group A - comprising sound/unprepared teeth (control). Group B, C, and D were root filled and restored with nanohybrid composite resin. Group C &ndash; were restored with fiber in base of cavity, and Group D &ndash; were restored with fibre in occlusal aspect. Fracture resistance was evaluated using&nbsp; MECMESIN10i universal testing machine. <strong>Result</strong>: No statistically significant difference was observed between control group and others. However Group C closely resembled the fracture strength to Group A (control group). Group D showed lowest fracture resistance among all. <strong>Conclusion</strong>:&nbsp; Fibre reinforcement in base of cavity can prove an alternate technique as a permanent restoration after root canal treatment.<br>
<strong>Key words</strong> : fibre reinforced composite (FRC);&nbsp; fracture resistance; maxillary premolar; polyethylene fibre.</p>
