Table 6: Advantages, disadvantages, and indications of different dowel systems used in this study.

Dowel Systems Glass Fiber Dowel Indirect Resin Dowel Prefabricated Metal Dowel
Advantages   • Esthetic
  • Moderate fracture resistance
  • Removability
  • Moderate esthetic
  • Better fitting
  • High strength
  • Maximum fracture resistance
  • Removability
Disadvantages   • Mostly radiopaque   • Least indirect resin dowel and post   • Least esthetic
  • Radiopaque
Indications   • Indicated when high esthetic is required   • Useful teeth without loss of tooth structure   • Useful for grossly decayed teeth and high strength is required
