Assessment of periodontal dehiscence and fenestration using ultrasonography and cone-beam computed tomography: an in vitro study.

Objectives: This study sought to assess the diagnostic value of ultrasonography (USG) and cone-beam computed tomography (CBCT) for the visibility of periodontal defects.

Materials And Methods: We created 37 periodontal defects (dehiscence and fenestration) in fresh sheep mandibles. Two dentomaxillofacial radiologists assessed the CBCT and ultrasonographic images for the presence of defects.

Expression of sirtuins 1 in placenta, umbilical cord, and maternal serum of patients diagnosed with placenta accreta spectrum.

Objective: Placenta accreta spectrum (PAS) is defined as the attachment of the placenta to the uterine wall in varying degrees. However, the studies have explored that the underlying molecular mechanisms of the PAS are very limited. Sirtuins 1 (SIRT1) is associated with placental development by controlling trophoblast cell invasion and remodeling of spiral arteries.

The relationship between primary ovarian insufficiency and gene variations: a prospective case-control study.

Around 70 percent of cases of Primary Ovarian Insufficiency (POI) etiology remain unexplained. The aim of our study is to contribute to the etiology and genetic background of POI. A total of 37 POI patients and 30 women in the reproductive period were included in this prospective, case-control study between August 2020 and December 2021.

Preventive effects of systemic Pistacia eurycarpa Yalt. administration on alveolar bone loss and oxidative stress in rats with experimental periodontitis.

Objective: This study aimed to investigate the effects of systemic administration of P. eurycarpa Yalt. plant extract on alveolar bone loss and oxidative stress biomarkers in gingival tissue in a rat model of experimental periodontitis.

Assessing the reliability of CBCT-based AI-generated STL files in diagnosing osseous changes of the mandibular condyle: a comparative study with ground truth diagnosis.

Objectives: This study aims to evaluate the reliability of AI-generated STL files in diagnosing osseous changes of the mandibular condyle and compare them to a ground truth (GT) diagnosis made by six radiologists.

Methods: A total of 432 retrospective CBCT images from four universities were evaluated by six dentomaxillofacial radiologists who identified osseous changes such as flattening, erosion, osteophyte formation, bifid condyle formation, and osteosclerosis. All images were evaluated by each radiologist blindly and recorded on a spreadsheet.
