THE NEW BEST RESIN COMPOSITE FOR ROOT CANAL TREATMENT IS FOUND.
Following an endodontic treatment, if the remaining tooth structure
is not adequate for the stable retention of a direct core build-up material,
insertion of post into the canal is a treatment option to retain the core. The
post can be metal, fiber, or ceramic. Metallic posts have poor stress distribution
due to differences in the elastic modulus of metal and dentin, which can
occasionally cause root fracture and the potential discoloration of surrounding
soft tissue. The use of glass fiber posts has advantages, such as more rapid
treatment and better biocompatibility, aesthetics, corrosion resistance, and similar
biomechanical properties to dentin.
When loaded, adhesively luted
endodonticreinforced with glass or quartzlead to better homogeneous tension
distribution than rigid metal or zirconium oxide ceramic. Moreover, it has been
reported that, compared with traditional metallic cast posts, glass fiber posts
decrease the likelihood of irreparable root fracturesTo prevent cohesive
failure of the material that enhances the retention of root dentin, the use of
resin composites should be evaluated. Low elastic modulus (with respect to
fiber posts) and direct bonding to the root dentin are advantages of resin
composites. PDF LINK.......
