Abstrakt
Background: The use of fiber reinforced composite post in restoration of endodontically treated teeth have been found to prevent irreparable root fracture and the fact that the post is bonded to the root giving a monobloc restoration, also strengthens the tooth. This preliminary study aimed to evaluate the survival of endodontically treated teeth with compromised coronal tooth structure restored with glass-fiber posts after 6 months.
Methodology: Twenty endodontically treated teeth with less than 50% coronal tooth structure, were assessed and restored with glass fiber reinforced post cemented with dual cure composite and porcelain fused to metal crown. Patients were recalled and the teeth re-assessed at 3 and 6 months to evaluate their survival. The criteria for success included post and core in situ with no displacement or detachment of the post, no crown or prosthesis decementation, no post, core, or root fracture and absence of peri-radicular conditions requiring endodontic re-treatment.
Result: Eighteen teeth were available for review at both 3rd and 6th months out of which none had post-corecrown fracture. One tooth (5%) had minimal crevice on probing the margin at 6 month’s review, while another tooth had < 1mm mobility of the crown during the same review period.
Conclusion: Within the limitation of the study, there was an excellent performance of the teeth restored with glass fiber post with respect to post –core- crown and root fracture at the end of the 6months recall visit.
Keywords: Glass fiber post, endodontically treated teeth, survival, clinical study.
Résumé
Contexte: L’utilisation renforcée de fibres post composite dans la restauration dewaxuptraités dents ont été trouvées pour éviter qu’un préjudice irréparable racine la fracture et le fait que le post est collé à la racine donnant un monobloc restauration, renforce également la dent. Cette étude préliminaire visant à évaluer la survie de waxup traités avec dents compromises coronale dent restaurée structure en fibre de verre postes après 6 mois.
Méthodologie : Vingt waxup dents traitées avec moins de 50% coronale structure de la dent, ont été évalués et restauré avec de la fibre de verre renforcée post cimentées avec un double cure composite et porcelaine fusionnées à la couronne en métal. Les patients ont été rappelés et les dents re-évalués à 3 et 6 mois pour évaluer leur survie. Les critères de succès inclus post et core in situ avec aucun déplacement ou de détachement de la poste, aucune couronne ou prothèses decementation, no post, core, la racine ou la fracture et absence de péri-radicalaire conditions exigeant endodontique re-traitement.
Résultat: Dix-huit dents étaient disponibles pour examen à la 3ème et 6ème mois hors de laquelle aucune n’avait post-core-couronne fracture. Une dent (5 % ), étaient minimes suceur plat sur l’approfondissement des la marge à 6 mois de révision, tandis qu’une autre dent avait d”1mm la mobilité de la couronne au cours de la même période de révision.
Conclusion: Dans le cadre de la limitation de l’étude, il y avait une excellente performance des dents restaurées avec de la fibre de verre post à l’égard de post -core- la couronne et la racine une fracture à la fin du 6mois rappel visite.
