Filter by:In patients with endodontically treated teeth, will the Indirect Milled composite Endo-crown restorations have a better clinical performance and more wear resistance than the Direct Bulk-Fill resin composite restorations over one year? Primary Objective: To evaluate clinical performance of different Techniques of Composite Restorations (Indirect restorations using a CAD/CAM grinding process, BRILLIANT Crios, Coltène/Whaledent AG, Switzerland or Direct a light-cured, bulk-fill nanocomposite restorative material, Filtek™ One Bulk Fill Restorative, 3M ESPE Dental Products, USA) in Endodontically treated posterior teeth.
Background: A real challenge faces practitioners in dealing with permanent molars in young patients starting from proper selection of endodontic treatment system till the type of final coronal restoration. For permanent molars in young age patients, which system should be followed to guarantee better performance and enhance the integrity of such weakened teeth? The question most commonly asked. Purpose: To evaluate two-year clinical performance of endocrowns as permanent restorations for endodontically treated molars in young age.
The aim of this study was to evaluate the survival rate and healing time of compromised teeth and seriously compromised teeth that were endodontically treated in patients which received bisphosphonate therapy . Clinical complications, success and survival rate was reported. Mean clinical parameters, clinical symptoms and presence of periapical radilucency were recorded.
The purpose of this randomized clinical trial is to evaluate the incidence of postoperative pain after retreatment after apical enlargement and sonic activation assisted irrigation. The presence of postoperative pain will assess after retreatment cases at 12, 24, 48, 72 hrs and 1 week.
The purpose of this randomized clinical trial was to evaluate the incidence of postoperative pain after root canal treatment using different final irrigation protocols. Patients whom need root canal treatment for first time were included. The presence of postoperative pain was assessed after root canal treatment cases at 12, 24, 48, 72 hrs and 1 week.
Clinical performance of indirect adhesive restorations - onlays, overlays- luted with light-cured composite resin will be evaluated over three years.
In fixed prosthodontic treatment, deflection of gingival tissues for diagnosis or making an impression is one of the important phases. Gingival displacement is defined as "displacement of gingival tissues both in vertical and lateral dimensions". Lateral retraction displaces the tissues so that an adequate bulk of impression material can be interfaced with the prepared tooth. Vertical retraction exposes the uncut portion of the tooth apical to the finish line Conventional gingival retraction cord technique may injure the healthy epithelial lining and result in postoperative gingival recession The diode laser has been used for displacing gingiva to make a definitive impression. Rather than displacing gingival tissue, it removes the epithelial lining from the sulcus. The aim of the Study is to compare between the Ultrapak retraction cord and diode laser regarding the amount of vertical and lateral retraction and patient comfort.
The use of full cuspal coverage restoration for the management root treated teeth was advocated by many clinical studies and supported by systematic reviews. However, most of the studies did not take into account the amount of tooth structure remaining before providing cuspal coverage. The strength and fracture resistance of the tooth has been shown to be positively correlated with the amount of tooth structure remaining. A more conservative treatment option could be selected for a root treated tooth with good amount of remaining tooth structure such as direct restorations. The aims of this randomized clinical trial is to compare the survival and success of root treated teeth with occlusal cavities and at least three intact axial walls, when restored through the use of indirect full cuspal coverage restorations vs direct composite resin restorations.
A short fiber reinforced composite base filling material has been shown to improve the strength of a direct composite filling significantly. It prevents fracture propagation and reduces shrinkage strain. These features are needed especially in endodontically treated molars, as root-canal treated teeth are structurally compromised and their restoration is associated with technical failures such as debonding and vertical root fractures. Application on this core fiber-reinforced composite (FRC) material is simplified when compared to post and core techniques commonly used to restore endodontically treated teeth. Clinically, the use of core FRC offers a cost-effective way to restore endodontically treated molars without root canal involvement. The purpose of this study is to compare the clinical performance of endodontically treated molars restored with either direct composite restorations with a FRC substructure, or with indirect full-ceramic onlay restorations, i.e. endo-crowns.
The aim of this study is to evaluate the clinical performance of lithium disilicate crowns restoring endodontically treated teeth with two occlusal preparation schemes.
