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

Proteomic Sex Estimation From Embedded Tooth Enamel

Archaeometry, EarlyView.
ABSTRACT Teeth hold insights into childhood diet, health and demography—including chromosomal sex. Proteomic analysis can detect peptide biomarkers from amelogenin genes encoded on X and Y chromosomes, allowing sex estimation. Embedding resins, necessary for thin sectioning teeth, can damage analytical systems, preventing proteomic analysis. We present

Ecological variability of Hippopotamus antiquus from the late Early–Middle Pleistocene of Megalopolis Basin (Greece): Evidence for dynamic habitats in a glacial microrefugium

Boreas, EarlyView.
This study investigates the ecology of the extinct European Hippopotamus from the late Early–Middle Pleistocene (c. 900–400 ka) sequence of the Megalopolis Basin, a glacial microrefugium for temperate taxa in southern Greece. Using stable carbon (δ13C) and oxygen (δ18O) isotope analyses and microwear analyses of Hippopotamus dental elements, we ...

Short Dental Implants as Strategic Support for Removable Partial Dentures in Mandibular Free‐End Situations: A 3‐Year Prospective Cohort Study

Clinical Oral Implants Research, EarlyView.
ABSTRACT Objectives This study aimed to assess the mid‐term clinical performance of short implants as strategic support for mandibular removable partial dentures (RPDs) with free‐end situations. Methods Subjects wearing lower RPDs in Kennedy Class I situations received two supporting posterior implants.

Premature Occlusal Contacts Induce MRONJ in Osseointegrated Dental Implants: An Experimental In Vivo Study

Clinical Oral Implants Research, EarlyView.
ABSTRACT Objectives Medication‐related osteonecrosis of the jaw (MRONJ) is a debilitating condition associated with antiresorptive agents (ARAs) and can occur around well‐osseointegrated dental implants. Although implant presence–triggered osteonecrosis (IPTO) has been primarily linked to bacteria‐related peri‐implantitis, whether occlusal trauma ...

Adhesion of Newly Developed Composite Resin Splinting Materials to Enamel: Effect of Enamel Surface Treatment

Dental Traumatology, EarlyView.
ABSTRACT Background/Aim To evaluate the shear bond strength (SBS) of newly developed composite resin materials intended for dental splinting to enamel and to determine whether phosphoric acid etching alone provides reliable adhesion. Material and Methods Four experimental materials (G‐Fix, Light Fix, Ortho Connect, and Ortho Connect Flow) were compared
