Abstract

Objective: The purpose of this study was to assess patient satisfaction, gross fracture and marginal adaptation of e.max press endocrowns versus e.max press crowns retained with Fiber reinforced composite post (FRCP) and core in upper anterior teeth. Material and methods: The present study included 24 patients seeking root canal treatment in anterior upper arch. The patients received root canal treatment (RCT) then they were randomly assigned into two groups (n=12). The first group received preparation for the IPS e.max crowns retained with FRCP and core and the second group received preparation for the IPS e.max endocrowns. Press technique was used for the fabrication of both restorations using IPS e.max press ingots. Marginal integrity and gross fracture were evaluated using USPHS criteria and a questionnaire was conducted to evaluate patient satisfaction. Data were analyzed using IBM SPSS Statistics for Windows, Version 23.0. Armonk, NY: IBM Corp. Results: There was no statistical significant difference regarding gross fracture of both groups after 12 months (p-value = 0.093, Effect size = 0.447), meanwhile; group 1 was statistically significantly higher than group 2 regarding marginal integrity (p-value = 0.037, Effect size = 0.513). Regarding patient satisfaction FRCP and core group showed statistical significant higher satisfaction than endocrown group (p-value = 0.047, Effect size = 0.447). Conclusion: E.max press endocrowns revealed successful performance similar to e.max press crowns retained with FRCP in terms of gross fracture, however better marginal adaptation and patient satisfaction was obtained with e.max press crowns retained with FRC post and core group.

Highlights

Restoring endodontically treated teeth (ETT) continues to be a challenge in reconstructive dentistry
The loss of water and collagen cross-linking after root canal treatment (RCT) make ETT more brittle, due to structural change in the dentin. opposite to common belief there is no difference in moisture content between vital teeth and ETT, many studies support the hypothesis that loss of structural integrity associated with the access preparation results in increased cuspal deflection during function, which leads to a higher occurrence of fractures
The null hypothesis of this study was that there would be no significant difference between IPS e.max press endocrowns and IPS e.max press crowns retained with Fiber reinforced composite post (FRCP) and core system in terms of gross fracture, patient satisfaction and marginal integrity

Summary

Introduction

Restoring endodontically treated teeth (ETT) continues to be a challenge in reconstructive dentistry. There are challenges related to the use of FRCP and core system these challenges include; when the post space is too wide in the coronal aspect of the ETT, the cemented post may only contact the tooth in the most apical portion of the post space. Under these conditions, post retention depends primarily upon the cement. Adhesion ensures sufficient material retention without the use of aggressive macro-retentive technique [9, 10]
