ViSTooth: A Visualization Framework for Tooth Segmentation on Panoramic Radiograph [PDF]

open access: yesarXiv
Tooth segmentation is a key step for computer aided diagnosis of dental diseases. Numerous machine learning models have been employed for tooth segmentation on dental panoramic radiograph. However, it is a difficult task to achieve accurate tooth segmentation due to complex tooth shapes, diverse tooth categories and incomplete sample set for machine ...

Exploring developmental changes in femoral midneck cross‐sectional properties

open access: yesThe Anatomical Record, EarlyView.
The properties of femoral midneck cross‐sections exhibit a unique growth pattern that is characterized by shape changes during adolescence. Abstract This research delves deeper into previous works on femoral cross‐sectional properties during ontogeny by focusing for the first time on the human femoral midneck. The ontogenetic pattern of cross‐sectional

Exposed weapons: A revised reconstruction of the facial anatomy and life appearance of the saber‐toothed cat Megantereon (Felidae, Machairodontinae)

open access: yesThe Anatomical Record, EarlyView.
Abstract Megantereon was a widespread saber‐toothed felid from the Pliocene and Pleistocene of the Old World and North America, but its rarity in the fossil record makes it complicated to restore its life appearance. Lack of complete specimens makes it necessary to combine information from fossils of different individuals to reconstruct their facial ...

Fermented lingonberry juice's effects on active MMP‐8 (aMMP‐8), bleeding on probing (BOP), and visible plaque index (VPI) in dental implants—A clinical pilot mouthwash study

open access: yesClinical and Experimental Dental Research, Volume 8, Issue 6, Page 1322-1330, December 2022., 2022
Abstract Objectives We aimed to study the effects of fermented lingonberry juice (FLJ) as a mouthwash on the levels of active matrix metalloproteinase‐8 (aMMP‐8) in peri‐implant sulcular fluid (PISF), bleeding on probing (BOP), and visible plaque index (VPI). We hypothesized that FLJ rinsing could reduce inflammation (aMMP‐8 and BOP) and microbial load

Histochemical indications for a chemically complex signal produced by the cervical gill slit gland of the pygmy sperm whale (Kogia breviceps)

open access: yesThe Anatomical Record, EarlyView.
Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland

Diagnostic value of routine dental radiographs for predicting the mandibular canal localization validated by cone‐beam computed tomogram measurements

open access: yesClinical and Experimental Dental Research, Volume 8, Issue 6, Page 1440-1448, December 2022., 2022
Abstract Objectives To test the hypothesis that routine dental radiographs can be used to draw conclusions regarding the mandibular canal (MC) localization. Material and Methods A total of 108 radiographs (36 orthopantomograms [OPTs], 36 lateral cephalograms [LCs], and 36 cone‐beam computed tomograms [CBCTs]) of 36 patients were analyzed.

Is cranial anatomy indicative of fossoriality? A case study of the mammaliaform Hadrocodium wui

open access: yesThe Anatomical Record, EarlyView.
Abstract Determining the ecology of fossil species presents considerable challenges due to the often fragmentary preservation of specimens. The mammaliaform Hadrocodium wui from the Jurassic of China is known only from the cranium and mandible but may have had a fossorial lifestyle.
