Aim: To evaluate and compare the fracture resistance and microleakage of tooth fragment reattachment using light-cure and dual-cure flowable composites under different pretreatment conditions. Materials and methods: The present in vitro study was conducted on 64 extracted caries-free premolars that were divided into eight groups depending upon the pretreatment condition and the composite material used for reattachment. Fracture resistance and microleakage following reattachment were evaluated. Data was analyzed using Statistical Package for the Social Sciences (SPSS) 16.0 for Windows (SPSS Inc., Chicago, Illinois, United States of America, 2001). Student t-test and analysis of variance (ANOVA)/Kruskal–Wallis test were. The level of significance was set at p ≤ 0.05. Results: Fracture resistance was significantly greater, and microleakage was significantly lesser when rehydrated fracture fragments were preconditioned with ethylenediaminetetraacetic acid (EDTA) before reattachment. Conclusion: Dual-cure composite resin (Fill-Up, Coltene) proved to be a better material for increasing the fracture resistance of reattached fracture fragments. Clinical significance: Fragment reattachment has been recommended to restore uncomplicated crown fractures if the fracture fragment is available since it serves as an esthetic and biological restoration that is quick and easy to place, cost-effective, and conservative. Fragment bonding is affected by the restorative material used for reattachment as well as the condition of the fractured dentin. Rehydration of dentin and pretreating it with EDTA, as well as using dual-cure composites to reattach fractured fragments, can significantly improve the strength and decrease microleakage following fragment reattachment.
