Efficacy of Reverse Metal vs Glass Fiber and Polyethylene Fiber Posts in Esthetic Rehabilitation of Severely Decayed Primary Anterior Teeth: A Randomized-controlled Clinical Trial

to intraradicular dentin is challenging due to the complexity and sensitivity of the technique.6 A new fiber system called Ribbond Triaxial has been introduced as a result of further advancements in these systems.The benefits of Ribbond fiber include its visual appeal, 7 higher strength, IntroductIonThe esthetically restoring severely decayed primary anterior teeth has been a challenge for pediatric dentists, not only due to the scarcity of materials but also because the children who require such restorations are typically the youngest and least manageable group of children. 1 The objective of restoring lost tooth structure is to maintain function, prevent psychological difficulties that influence the child's self-esteem, and ensure the child's positive attitude, lowering anxiety. 2 Many types of root canal posts are there to restore severely damaged primary teeth, including priory manufactured orthodontic wire in alpha/gamma/omega forms, metallic posts with macro retention, composite resin in the form of short post, and biologic posts using direct or indirect techniques. 2 However, the optimal post and core in pediatric dentistry should provide appropriate retention and resistance without impeding the eruption course.The adaptation of the post and core to the inner dentinal wall, which is dictated by adhesive and cohesive forces, 3 has resulted in the development of newer fiber reinforced composites.4 Glass fiber posts (GFP) are made up of unidirectional glass fibers embedded in a resin matrix that reinforces the dowels without reducing their modulus of elasticity.5 GFP has stronger flexural strength, fracture resistance, and cement interfacial adhesion, but it is more difficult to utilize for an inexperienced clinician because of fibers propensity to separation.Furthermore, bonding
