A vivo study on dowel crown with more aesthetic and healthy Fiber Reinforced Composite post system

Abstract

Statement of problem. Patients having grossly carious teeth with broken down crown are needed to be restored with post & core after endodontic treatment. Root canal posts are widely used & come in a variety of metals & forms. However, cast metal posts, although better than other post & core systems, still possess some disadvantages, like corrosion & discoloration at the gingival margin of the treated tooth & cause aesthetic problem. These problems are overcome with the recently introduced post & core material. The fiber reinforced composite post & core material is a superior & efficient alternative to cast post. Purpose. The purpose of this study was to investigate the success of fiber reinforced composite post & core system over conventional metallic system in regards of corrosion & discoloration resistance with periodontal condition on post treated tooth. Materials & Methods. This was a prospective study, conducted in the department of Conservative Dentistry & Endodontics, B.S.M.M.U. 40 patients were purposively selected who attended in this department with grossly carious teeth with badly broken crown without apical infection as the subject of this study & divided in two groups. 20 patients were included in group A as case subjects & they were treated with fiber reinforced post & core system. 20 patients were included in group B as control subjects. They were treated with conventional cast metallic post & core system. After twelve months, recorded data were compiled on a master chart and statistically analyzed. Chisquare test and t-test (unpaired) were done for statistical significance (P<0.05). Results. Very highly significant difference (p<.001) was observed between the groups in the evaluation of resistance to corrosion & discoloration, there were no significant difference (p>.05) in periodontal evaluation Conclusion. This study revealed that fiber reinforced composite post & core system can overcome the problems faced by the metallic post & core system. So it can be concluded that fiber reinforced composite post & core system can be a promising alternative in comparison to metallic post & core system.DOI: http://dx.doi.org/10.3329/cdcj.v9i1.11832 City Dental College Journal Vol.9(1) 2012 15-18
