Domination Versus Sisterhoods in the Blood Microbiota of Migrating Birds: Patterns of Within‐ and Between‐Individual Blood Parasite Diversity Revealed Through Metabarcoding

open access: yesIntegrative Zoology, EarlyView.
Avian haemosporidian blood parasites are typically identified through Sanger sequencing of a partial cytochrome b fragment, the MalAvi barcoding region. Next‐generation sequencing is seldom used for avian blood parasite identification; this study demonstrates a higher detection rate of co‐infections via metabarcoding and its possible implications ...

Effect of Kinematics and Speed on Filling Material Removal, Canal Transportation, and Apical Extrusion During Retreatment of Curved Canals

open access: yesAustralian Endodontic Journal, EarlyView.
ABSTRACT This study evaluated the effects of kinematics (reciprocating vs. continuous rotation) and rotational speed (350 vs. 1200 rpm) on filling removal, canal transportation, and apical extrusion during retreatment of curved root canals. Vertucci type II mesial roots of mandibular molars were prepared, filled, and scanned by micro‐computed ...

Horizontal Ridge Augmentation Using an rhBMP‐2 Loaded Volume‐Stable Collagen Matrix Compared to Guided Bone Regeneration: A Preclinical In Vivo Study

open access: yesJournal of Clinical Periodontology, EarlyView.
ABSTRACT Aim To investigate whether incorporation of recombinant human bone morphogenetic protein‐2 (rhBMP‐2) into a volume‐stable collagen matrix (VCMX) enhances horizontal ridge augmentation compared with VCMX alone or guided bone regeneration (GBR). Methods Chronic horizontal ridge defects were created in five canines.
