Fragment reattachment using a technique with no preparation and an adhesive system associated with an intermediate composite with good mechanical properties can restore part of the resistance of the fractured tooth
BACKGROUND / AIMS Fragment reattachment is a procedure that offers advantages , such as preservation of tooth structure and maintenance of color , shape , and translucency of the original tooth .
The aim of this study was to analyze the reattachment techniques used to restore anterior teeth fractured by trauma .
Comparison of the fracture resistance of reattached incisor tooth fragments using 4 different materials.
AIM To evaluate and compare the fracture resistance of reattached teeth using four different material s. MATERIAL S AND METHODS 150 extracted human permanent maxillary incisors were r and omly 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 material s. 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 )
