Abstract
An evaluation of the effect of the chemical and mechanical surface treatment of the glass fibre posts on the retention of the composite resin core material: An in-vitro study - APRD- Print ISSN No: - 2581-4796 Online ISSN No:- 2581-480X Article DOI No:- 10.18231/j.aprd.2019.025, IP Annals of Prosthodontics and Restorat
Highlights
To study the effect of the chemical and mechanical surface treatment of the glass fiber posts on the retention of the composite resin core material Aims & 0bjectives: To evaluate the influence of glass fibre post surface treatment with hydrofluoric acid [HF], hydrogen peroxide [H2O2] air abrasion via Al2O3 and chemical treatment with Silane coupling agent on tensile bond strength with composite resin core material
Owing to the fact that much of all of the coronal tooth fiber posts are ready to use whereas the structure, which normally would have been used in the construction of a cast post and core is more time retention of a restoration, has been destroyed by caries, consuming and demands extra clinic and laboratory previous restorations, trauma and the endodontic time
Tensile Strength of Group II (Hydrofluoric Acid (60 sec.) and Silane Coupling Agent): Tensile strength of specimens of Group II ranged from 15.2915.98 MPa
Summary
To study the effect of the chemical and mechanical surface treatment of the glass fiber posts on the retention of the composite resin core material Aims & 0bjectives: To evaluate the influence of glass fibre post surface treatment with hydrofluoric acid [HF], hydrogen peroxide [H2O2] air abrasion via Al2O3 and chemical treatment with Silane coupling agent on tensile bond strength with composite resin core material. Elastic modulus to dentine, producing a stress field This objective applies to each tooth in the dentition similar to that of natural teeth, whereas metal posts and more importantly to the dentition itself. Owing to the fact that much of all of the coronal tooth fiber posts are ready to use whereas the structure, which normally would have been used in the construction of a cast post and core is more time retention of a restoration, has been destroyed by caries, consuming and demands extra clinic and laboratory previous restorations, trauma and the endodontic time. M. Vano, et al(2006) conducted a study on the restorative or prosthetic rehabilitations of adhesion between fibre posts and composite resin endodonticallly treated teeth depends on the quality of cores: and concluded that retention increased on the restoration, on its clinical adaptation and on the various surface treatment as compared to the normal to health of the supporting tissue.
