Combination of autogenous dentin graft and allograft for horizontal ridge augmentation: A case report

Clinical Advances in Periodontics, EarlyView.
Abstract Background Autogenous particulate dentin has emerged as one of the promising biocompatible alternatives to traditional bone graft materials in alveolar ridge augmentation. Although its clinical success is documented, comprehensive studies combining histological and radiographic evaluations remain limited. This case report addresses this gap by

Impact of Hydroxyapatite Tooth Paste on Enamel Surface Roughness of Artificially Demineralized Permanent Teeth (An in vitro study). [PDF]

Al-Rafidain Dental Journal
Aims: The current study aimed to evaluate the impact of hydroxyapatite (HA) toothpaste, synthesized from chicken eggshell powder (CESP) on the surface roughness of artificially demineralized enamel, in comparison to sodium fluoride paste via profile ...

Application of Ultrasonic Sensors for Determining the Height of Dynamic Two‐Phase Layers in Tray Columns

Chemie Ingenieur Technik, EarlyView.
Ultrasonic sensors are evaluated for their applicability in dynamic gas–liquid systems. By comparing sensor data with two independent optical reference methods, their robustness and reliability are demonstrated under varying flow conditions and tray geometries in column systems.

In-vitro Thermal Maps to Characterize Human Dental Enamel and Dentin

Frontiers in Physiology, 2017
The crown of a human tooth has an outer layer of highly-mineralized tissue called enamel, beneath which is dentin, a less-mineralized tissue which forms the bulk of the tooth-crown and root.

Modelling of continuous low‐temperature emulsion co‐polymerization in 3D‐printed reactor

The Canadian Journal of Chemical Engineering, EarlyView.
A kinetic model for the emulsion copolymerization of butyl acrylate/styrene at low temperatures is proposed and validated against experiments with a redox initiator system. The model was successfully transferred to a 3D‐printed tubular reactor and conversions of more than 80% and small particles sizes below 40 nm were observed.

Effect of fluoride varnish and dentifrices and its combination on deciduous enamel demineralization: An In vitro study

Journal of Pharmacy and Bioallied Sciences, 2017
Introduction: Dental caries remains the most important dental health problem in developing countries. Application of varnish on tooth surfaces is shown to promote the uptake of firmly bound fluoride by enamel, which is considered important.

Bioactivation and Metabolism of Amino Acid MDMA Prodrugs in Zebrafish Embryos, Human Liver S9, Whole Blood, and Microdosed Human Urine

Drug Testing and Analysis, EarlyView.
Bioactivation and metabolism of MDMA prodrugs: MDMA‐Trp, MDMA‐Lys, MDMA‐Gly showed unique urine screening targets only for MDMA‐Trp, while biomarkers for MDMA‐Lys and MDMA‐Gly consisted of MDMA and known MDMA metabolites. Conversion of amino acid prodrugs to MDMA in pHLS9, zebrafish embryos, and humans. ABSTRACT 3,4‐Methylenedioxymethamphetamine (MDMA)

Comparison of the Effect of Three Cements on Prevention of Enamel Demineralization Adjacent to Orthodontic Bands

Journal of Dental Research, Dental Clinics, Dental Prospects, 2012
Background and aims. This in vitro study was designed to compare enamel demineralization depths adjacent to bands cemented with zinc polycarboxylate, glass ionomer (GI) and resin-modified glass ionomer (RMGI), in order to achieve minimal enamel ...

Streptozotocin induced hyperglycemia in the axolotl

Developmental Dynamics, EarlyView.
Abstract Background Diabetes is a group of diseases characterized by loss of β cell mass and/or function, resulting in hyperglycemia. With no established curative treatment, this has initiated research in β cell regeneration. Current animal models have either limited regenerative capacity (mice) or small size and evolutionary distance from humans ...

Fish Scales: A Multifunctional Biomaterial from Nature

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...
