Refractory apical periodontitis associated with a calculus-like deposit at the root apex

Journal of Dental Sciences, 2010
In this case report, we describe a refractory case in which a calculus-like deposit was found at the apical root surfaces of two adjacent teeth. This case involved a 45-year-old male with a sinus tract at the labial mucosa of the maxillary left central ...

Immediate anterior tooth replacement by using an esthetic fixed bridge: A case report

Medicina Clínica Práctica, 2020
Introduction: Loss of teeth due to extraction is often found in some cases. Preserving interproximal soft tissue and preventing alveolar bone from collapse due to tooth extraction is the most challenging issue. Ovate pontic design can give a natural look

Identification of a Force‐Induced Sox9+Acan+ Transitional Subpopulation Linked to FGF2–FGFR2–ERK Signaling in Orthodontic Bone Remodeling

Advanced Science, EarlyView.
Mechanical loading induces a previously unrecognized Sox9+Acan+ transitional mesenchymal cell population in the periodontal ligament that promotes osteoclastogenesis via the FGF2–FGFR2–ERK axis. Targeting this mechanoresponsive stromal population using a localized GelMA@siRNA delivery strategy attenuates pathological osteoclast overactivation and root ...

Nance‐Horan Syndrome: Further Delineation of the Affected Male and the Female Carrier Phenotypes

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Nance‐Horan syndrome (NHS; OMIM 302350) is a rare, X‐linked syndrome characterized by bilateral congenital cataracts leading to profound vision loss, specific dental anomalies including characteristic screwdriver blade‐shaped incisors, facial anomalies, and intellectual disability.

Non‐RASopathy Genetic Syndromes Identified as the Molecular Cause of Disease in Patients Previously Diagnosed With Noonan Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Noonan Syndrome (NS) is a clinically and genetically heterogeneous condition characterized by typical facial dysmorphisms, short stature, congenital heart defects, and developmental delays. While variants in genes such as PTPN11, SOS1, and RAF1 account for most genetically confirmed cases, diagnosis is challenging due to phenotypic overlap ...

A novel inhaled anesthesia technique for concurrent direct laryngoscopy in rats

Animal Models and Experimental Medicine, EarlyView.
Our novel nose cone anesthetic technique allows the use of gas anesthesia during concurrent direct laryngoscopy. Inhaled anesthesia not only has a better safety profile for rats, but also increases lab efficiency when compared to injectable anesthesia. Abstract The current anesthetic standard for laryngoscopy in rats utilizes injectable intraperitoneal

Mandible composition and properties in two selected praying mantises (Insecta, Mantodea)

The Anatomical Record, EarlyView.
Abstract Insects process their food with their cuticle‐based mouthparts. These feeding structures reflect their diversity and can, in some cases, showcase adaptations in material composition, mechanical properties, and shape to suit their specific dietary preferences.

Synapsids and sensitivity: Broad survey of tetrapod trigeminal canal morphology supports an evolutionary trend of increasing facial tactile specialization in the mammal lineage

The Anatomical Record, EarlyView.
Abstract The trigeminus nerve (cranial nerve V) is a large and significant conduit of sensory information from the face to the brain, with its three branches extending over the head to innervate a wide variety of integumentary sensory receptors, primarily tactile.
