Surface hardness of CEM cement and cold ceramic cement across different pH settings [PDF]

Journal of Dental Materials and Techniques
Objective: This study aimed to assess the surface microhardness of calcium-enriched mixture cement (CEM) and cold ceramic (CC) cement after being cured in environments with different pH values.Methods: Sixty maxillary canines were obtained.

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Dental Cements

Scientific Bulletin of Valahia University - Materials and Mechanics, 2017
Abstract Calcium-phosphate cements is one of the most popular types of biomaterials, both due to their specific properties of self - setting and of their superior biocompatibility. Although in general the phosphocalcic cements, which are the subject of the present paper, have somewhat lower mechanical properties than other

Anterior cingulate cortex neuron subtypes differentially regulate seizures

Epilepsia, EarlyView.
Abstract Objective This study aimed to investigate the regulatory roles of distinct neuronal subtypes within the anterior cingulate cortex (ACC) in acute seizures and to identify cell type‐specific mechanisms underlying seizure modulation in this region. Methods Acute seizure models were established in mice via pentylenetetrazol injection.

β‐Hydroxybutyrate reduces neuronal excitability via GIRK channels

Epilepsia, EarlyView.
β‐Hydroxybutyrate decreases neuronal excitability by activating GIRK channels through HCAR2 signaling, providing a cellular mechanism that may contribute to the antiseizure effects of the ketogenic diet. Abstract Objective The ketogenic diet is used to treat drug‐resistant epilepsy, yet the molecular mechanisms coupling metabolic state to seizure ...

Abnormal KCC2 expression and function in a mouse model of epilepsy and tuberous sclerosis complex

Epilepsia, EarlyView.
Abstract Objective Drug‐resistant epilepsy is a common, severe manifestation of the genetic disorder tuberous sclerosis complex (TSC). Although significant mechanistic and therapeutic advances have been made in TSC, treatments for seizures remain largely ineffective.

Epilepsy surgery: From bench to the clinics

Epilepsia Open, EarlyView.
Abstract Objective Recent advances in epilepsy surgery in patients with intractable epilepsy make it possible to study the mechanism of epilepsy in human brains. However, the true extent and propagation of each epileptogenic area from the epileptogenic focus in each patient is still difficult to perform “epilepsy cure” by surgery.

Comparative evaluation of calcium ion release from three bioceramic cements in simulated immature teeth with open apices [PDF]

Journal of Dental Materials and Techniques
Objective: This study aimed to evaluate the calcium ion (Ca2+) release from apical plugs formed by three different bioceramic cements in simulated immature teeth with open apices.Methods: In this in-vitro study, 66 single-rooted lower premolar teeth were

Effect of grain size of dental zirconia on shear bond strength of composite resin cement

Journal of Applied Biomaterials & Functional Materials, 2020
The effect of grain size of dental zirconia on the shear bond strength of composite resin cement was newly studied. Disc-shaped dental zirconia with small (sample S) and large (sample L) grains were made by sintering of pre-sintered dental zirconia at ...
