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 ...

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

Making Art or Studying Art? Routes to Ecological Thinking in the Secondary School Classroom

International Journal of Art &Design Education, EarlyView.
Abstract Art education scholarship has increasingly turned towards relational, ecological ways of thinking about the subject. This article asks whether that turn is reflected in how Art education is experienced and justified in the classroom. Drawing on interviews with students and an Art teacher in a rural state secondary school in England, it finds ...

Management of Periodontal Abscesses and Endodontic‐Periodontal Lesions—A Systematic Review

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Aim To evaluate the management of periodontal abscesses and endodontic‐periodontal lesions (EPLs). Methods Seven focused questions addressed outcomes such as pocket depth (PD), bleeding on probing (BOP), tooth loss or ovoid elevation. The literature search covered three electronic databases and manual sources for intervention studies.

Ultra‐High‐Speed Sintering of 3.5Y‐TZP Zirconia: Time Reduction Without Compromising Translucency

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To assess, firstly, the impact of three sintering speeds on translucency and grain size of 3.5Y‐TZP zirconia (Katana HT) across clinically relevant thicknesses, and secondly, the effect of thermocycling on translucency. Materials and Methods Disc specimens were fabricated at six thicknesses (0.7–2.0 mm) and sintered using SLOW (7 h),
