Multicenter RCT 6‐Year Survival of Zirconia‐Reinforced Lithium Silicate Endocrowns: 90° Shoulder Versus Butt‐Joint Margins

International Endodontic Journal, EarlyView.
ABSTRACT Objectives Margin design significantly influences endocrown biomechanical performance. Nevertheless, long‐term clinical data comparing margin designs within a singular zirconia‐reinforced lithium silicate (ZLS) system remain scarce. This study reports the 6‐year follow‐up results of a multicenter, prospective, randomized, assessor‐blinded ...

Degradation of Luting Cements Measured in vitro and in vivo

, 1983
The degradation of luting cements was quantified when these cements were held as a 20-μ m cement layer. The degradation process, which is mostly a sequence of absorption, disintegration, and solution, was expressed by a time-constant (τ ).

Prevention and Management of Tooth Discolouration of Endodontic Origin (DEO): A State‐of‐the‐Art Review

International Endodontic Journal, EarlyView.
ABSTRACT Background Tooth discolouration of endodontic origin (DEO) refers to an undesirable change in tooth colour arising from the pulp space as a result of reactive physiological processes, pathological processes or endodontic procedures and materials. As DEO frequently affects teeth in the aesthetic zone, it may substantially impair self‐esteem and

A Prospective Study on the Effect of Coronal Tooth Structure Loss on the Survival of Root Canal‐Retreated Posterior Teeth Restored With Metal Ceramic Crowns With up to 10‐Year Follow‐Up

International Endodontic Journal, EarlyView.
ABSTRACT Aim The primary aim of this study was to evaluate whether the volume of residual coronal tooth structure influences the survival of root canal‐retreated posterior teeth with up to 10‐year follow‐up. Secondary aims were to assess whether 12‐month radiographic findings and the Dental Practicality Index (DPI) could predict long‐term survival ...
