Aim: To evaluate and compare the fracture resistance of reattached teeth using four different materials. Materials and Methods: 150 extracted human permanent maxillary incisors were randomly divided into five groups of 30 teeth each of one control and four experimental groups. Teeth in experimental groups were sectioned 2.5 mm from incisal edge and reattached using four different materials. The reattached teeth were subjected to evaluate fracture resistance. Results: The mean fracture resistance of reattached teeth using resin modified glass ionomer cement, compomer, composite resin and dual curing resin cement was 8.10 ± 2.34, 11.15 ± 3.36, 17.11 ± 3.99 and 14.13 ± 3.71 kg respectively. Results showed highly significant difference between the groups ( P < 0.001). Conclusion: Fracture resistance of reattached teeth in the different groups varied from 24-51% of that for an intact tooth. Reattachment with composite resin provides highest fracture resistance ( P < 0.05). Reattachment with resin-modified glass ionomer cement was the weakest ( P < 0.05).
