Abstract
Back ground: Fiber reinforcement was introduced to clinical dentistry for the first time in the 1960s when investigators attempted to reinforce polymethyl- methacrylate dentures with glass or carbon fibers. It has recently been shown that crowns, bridges and posts made of FRC can be used successfully in dental practice and they are esthetically more acceptable than conventional metal ceramic crown. Aims: A prospective comparative cross-sectional study was performed involving 60 patients who attended in the out patients department of Prosthodontics, Faculty of Dentistry, BSMMU during the period of January 2007 to December 2008. Objective: Compare fiber-reinforced composite crowns and metal ceramic crowns according to attrition of opposing teeth. Methods: Clinical data were recorded from the randomly selected 60 patients divided in to tow groups experimental and control. Attrition of opposing teeth was indexed after California Dental Associations quality evaluation system. Results: In group A patients, 12(40.0%) were male and 18(60.0%) female. In group B patients 14(46.7%) were male and 16(53.3%) were female. All the patients were in grade I in both groups after 4 months. After 8 months all patients were in grade I in group A and 29(96.7%) patients were in grade I in group B. After 12 months all patients were in grade I in group A and 28(93.3%) patients were in grade I in group B. The difference was not statistically significant (p>0.05) in chi square test. Conclusion: The Fiber Reinforced Composite crown represents a valuable development in field of Prosthetic Dentistry. DOI: http://dx.doi.org/10.3329/updcj.v4i1.21161 Update Dent.

Highlights
Metal–ceramic crowns are clinically successful[1]
The observational study was done after 4 months, 8 months and 12 months interval of the cementation of crowns and data were collected according to selected parameters of esthetic status of opposing teeth
The percentage of attrition of opposing natural teeth of metal ceramic crown was higher than Fiber Reinforced Composite crown
Summary
Metal–ceramic crowns are clinically successful[1]. But the visibility of metal and the change in natural tooth translucency is aesthetically unfavorable. There have been several in vitro[4,5,6] and in vivo studies[7,8] of the properties of these composites and promising results have been reported for crowns,[9] and for fixed partial dentures.[10] these materials seem to provide excellent aesthetics,[11] some authors do not recommend composite materials for permanent restorations,[12,13] because of their unstable aesthetics, their increased wear[14] and their liability to plaque accumulation.[15] With the introduction of fiber reinforced composites, it seemed to be possible to eliminate these disadvantages of composites and to exploit their advantages, including the simple laboratory procedure, the lower costs and the possibility of repair This new generation of composites has given promising in vitro results with respect to color change,[16] wear[17] and fracture resistance.[18] The objective of this present prospective clinical study was the assessment of the attrition of the opposing teeth due to experimental fiber reinforced composite anterior crowns, compared with a metal–ceramic control group
