Changes in the Location of the Second Mesiobuccal Canal Orifice After Canal Preparation in Maxillary First Molars

Australian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated angular and linear positional changes of the second mesiobuccal (MB2) canal orifice in maxillary first molars and proposed a guideline for its localization. Twenty‐eight extracted maxillary first molars with four canals were analysed. After access cavity preparation, all canals except MB2 were instrumented. The initial and

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

Archaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

The Materiality of the Cloggs Cave Rockshelter's Painting, GunaiKurnai Country (East Gipplsland), Southeastern Australia

Archaeometry, EarlyView.
ABSTRACT The materiality of the white pigment motif at the Cloggs Cave rockshelter, near Buchan in GunaiKurnai Country (southeastern Australia), contains details about the cultural and environmental contexts in which the art was created and preserved. Here, we (1) present physicochemical analyses of the pigment composition; (2) explore implications for

Patch Test Results With Dental Series: An 18‐Year Retrospective Study

Contact Dermatitis, EarlyView.
Patch testing with dental series is recommended for patients with oral symptoms and/or a history of allergic contact dermatitis ‐ particularly before dental procedures. Routine pre‐implantation patch testing should be considered only on an individual basis rather than as a standard practice.

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
