A rare case of impacted mandibular premolar associated to dentigerous cyst and periodontal lesion clinical management and histological analysis

Oral & Implantology
Background: Dental cysts, particularly dentigerous cysts (DCs), are a common pathological condition affecting the jawbone. The literature categorizes DCs based on histology and associates them with impacted teeth, often leading to complications. However,

Genotypes and Phenotypes of Patients With TSPEAR‐Related Disorder: Evidence of a Predominant Dental Phenotype

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT TSPEAR (chr. 21q22.3) encodes a protein involved in tooth development and is predominantly expressed in the enamel knot. Biallelic loss of function variants in TSPEAR cause ectodermal dysplasia, tooth agenesis and sensorineural hearing loss. However, the role of TSPEAR in auditory processes is unclear.

Modeling chronic periodontitis in rats: Persistent alveolar bone loss mediated by periodontal pathogens

Animal Models and Experimental Medicine, EarlyView.
Irrigation of periodontal pockets with human periopathogens, in combination with a 14‐day ligature‐induced periodontitis protocol, significantly enhances alveolar bone loss and sustains bacterial colonization for up to 28 days following ligature removal, thereby more closely replicating the chronic nature of human periodontitis compared to the ligature

Surgical management of complex odontoma associated with agenesis of a molar

Contemporary Clinical Dentistry, 2018
Odontomas are mixed odontogenic tumors composed of mineralized tissue of ectomesenchymal origin. These are usually detected in routine radiographs and may have a variable etiology such as local trauma, genetic mutation, or infection.

Recombinant Human Neuregulin1‐β1 Significantly Reduces Schwannoma Growth in Mice

Annals of Neurology, EarlyView.
rhNRGβ1‐Replacement‐Therapy: Under physiological conditions, NRGβ1 is expressed on axons (in orange), where it activates ERBB2 receptors, facilitating successful nerve regeneration following injury. However, loss of NF2 leads to a reduction in NRGβ1‐expression and increased ErbB2 levels on Schwann cells (in green), which contributes to schwannoma ...

Diagnostic accuracy of conventional orthodontic radiographic modalities and cone-beam computed tomography for localization of impacted maxillary canine teeth

Science in progress
Background: Orthodontic treatment planning for an impacted canine tooth requires accurate information about its position. The aim of this study was to compare the diagnostic accuracy of two conventional orthodontic radiographic modalities with cone-beam ...

Small RNAs and tooth development: The role of microRNAs in tooth agenesis and impaction

Journal of Dental Sciences
Tooth development, or odontogenesis, is a complex process in which several molecular pathways play a key role. Recently, microRNAs, a class of approximately 20-nucleotide small RNA molecules that regulate gene expression, have been implicated in the odontogenesis process.

Antibacterial Applications of Black and Violet Phosphorus‐Based Biomaterials

Advanced NanoBiomed Research, EarlyView.
Black and violet phosphorus‐based biomaterials exhibit broad‐spectrum antibacterial efficacy in various infections, including bone, skin, ocular, dental, lung, and sepsis cases. Their antibacterial mechanisms include physical disruption, light‐driven effects, targeted drug delivery, and enhanced composite strategies.

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

The 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 ...

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

The Anatomical Record, EarlyView.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...
