Apicectomy and retrograde endodontic treatment for an unerupted mandibular cheek tooth

Equine Veterinary Education, EarlyView.
Summary Apicectomy combined with retrograde endodontic therapy is well documented in human and small animal dentistry, but its application in horses remains limited. This report describes the technique in a 2‐year‐old Warmblood mare with an unerupted, infected mandibular cheek tooth (307) that could not be accessed orally. Clinical examination revealed

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 ...
