Endodontic therapy, today, forms an integral part of everyday dental practice. The large number of teeth being treated endodontically makes it imperative for the dentists to provide satisfactory restoration for those teeth to remain intact within the dental arch as an integral functioning component. So this study was carried out to check the reinforcement of composite with polyethylene fibers placed in two different technique in root filled mandibular molar teeth with mesio-occlusodistal tooth preparation. Fifty freshly extracted molars were divided into five groups of ten teeth each. Group I: Intact teeth (positive control). Group II: Unrestored MOD prepared tooth (negative control). Group III: MOD tooth preparation restored with posterior composite resin. Group IV: Ribbond fiber was placed over the composite resin restoration and exposed fiber was covered with composite resin. Group V: Ribbond fiber was placed on the floor of the tooth preparation and the remaining prepared tooth was restored with composite resin restoration. The samples were subjected to compressive loading on Hounsfield tensometer until failure. The data were recorded and subjected to statistical analysis. Group-IV showed significantly higher fracture resistance than Group-V.
