Supernumerary teeth in patients with cleft lip and palate: the tooth germs do not separate

open access: yesDental Press Journal of Orthodontics, 2021
Introduction: Supernumerary teeth in cases of cleft lip and palate do not result from the division of normal germs before the formation of hard tissue. Deciduous and permanent teeth odontogenesis begins after the face has formed, either with or without ...

Molecular genetics of supernumerary tooth formation [PDF]

open access: yesgenesis, 2011
AbstractDespite advances in the knowledge of tooth morphogenesis and differentiation, relatively little is known about the aetiology and molecular mechanisms underlying supernumerary tooth formation. A small number of supernumerary teeth may be a common developmental dental anomaly, while multiple supernumerary teeth usually have a genetic component ...

Small Stokes Shift Induced Highly Efficient and Thermally Stable Broadband Near‐Infrared Antimonite Double Perovskite Emitters for Spectroscopy Applications

open access: yesAdvanced Science, EarlyView.
Highly efficient and thermally stable NIR photonic materials with emission over 830 nm are designed. A cation site substitution strategy is proposed to regulate the Stokes shift of the NIR emitters. The phosphors exhibit a full visible‐spectrum conversion ability from 400 to 800 nm, showing great promise for NIR spectroscopy applications in solar ...

An International ASXL3 Natural History Study: Deep Phenotypic Analyses Including Detailed Reports of a Milder Phenotype, Novel Associations, and Clinical Recommendations

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Natural History Studies can help inform clinician and caregiver expectations, form the basis of management guidelines, and provide a comparator for therapeutic intervention. In rare conditions, where collection of prospective longitudinal data is untimely and impractical, quasi‐natural history data—from multiple individuals of different ages ...

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

open access: yesThe Anatomical Record, EarlyView.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Discovery of sexual dimorphism of the laryngeal sac in the common minke whale Balaenoptera acutorostrata

open access: yesThe Anatomical Record, EarlyView.
Abstract Mysticetes, or baleen whales, have an air sac on the ventral surface of the larynx known as the “laryngeal sac.” The primary hypothesis regarding this structure's function is that it is involved in sound production. However, several other functions have been proposed, including air recycling, air storage, and even buoyancy control.

Removal of a supernumerary tooth displaced into the infratemporal fossa during extraction

open access: yesEuropean Oral Research, 2017
Accidental displacement of an impacted tooth into the infratemporal fossa (ITF) is a rare but serious complication because of the vulnerability of the surrounding anatomical structures.

Integrating mandibular evidence to assess morphological variation of the Australopithecus afarensis maxilla

open access: yesThe Anatomical Record, EarlyView.
Abstract Geometric morphometric analyses are used to explore variation of maxillary dental arcades of Australopithecus afarensis, expanding on the work of Hanegraef and Spoor, 2025 (Morphological variation of the Australopithecus afarensis maxilla.
