In situ biomimetic materials for dentin repair

open access: yesBMEMat, EarlyView.
This review primarily discusses the role and clinical application of key biomimetic materials for in situ dentin repair, providing a feasible foundation for future material and performance optimization in situ dentin regeneration. Abstract Dental defects, ranking among the most prevalent diseases globally, pose a serious threat to human health, with ...

In Vitro Evaluation of Surface Roughness and Color Variation after Two Brushing Protocols with Toothpastes Containing Different Whitening Technologies

open access: yesApplied Sciences
The aim was to evaluate the effect of different whitening toothpastes on the enamel surface roughness and color variation. Twenty-four molars were sectioned and divided into eight groups (n = 3) considering the following two factors under study ...

Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

open access: yesBiological Reviews, EarlyView.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Comparison of the mechanical properties of dentin and enamel determined by different nanoindentation techniques: conventional method and continuous stiffness measurement

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2010
The obtaining of mechanical properties as elastic modulus and hardness of enamel and dentin has been an important topic of study in material science. Due to the small size of the samples, nanoindentation test becomes an ideal technique for determining ...

Microhardness and chemical composition of human tooth

open access: yesMaterials Research, 2003
Hardness of human tooth, both in enamel and dentin, has been measured at different sites using a Vicker's diamond. In this work we show that these values are almost constant all along the enamel and dentin thicknesses.

The influence of process gas type on the enamel surface condition of a high power diode laser generated single-stage ceramic tile grout seal [PDF]

open access: yes, 2002
Almost all laser materials processing operations require the simultaneous use of an process or assist gas. This paper examines the use of O2, Ar, N2 and He as process gasses during the firing of a vitreous enamel to form a single-stage ceramic tile grout

Diet of bird‐like troodontid dinosaurs: synthesis of a contentious clade

open access: yesBiological Reviews, EarlyView.
ABSTRACT Troodontidae is a clade of small‐to medium‐sized maniraptoran theropods that mainly lived in Laurasia (modern Asia, North America and Europe) during the Jurassic and Cretaceous periods and are believed to have had a variety of diets. The uniqueness of troodontid teeth suggests that they diverged from the typical flesh‐based diet of non‐avian ...

Deciduous enamel 3D microwear texture analysis as an indicator of childhood diet in medieval Canterbury, England [PDF]

open access: yes, 2016
This study conducted the first three dimensional microwear texture analysis of human deciduous teeth to reconstruct the physical properties of medieval childhood diet (age 1-8yrs) at St Gregory's Priory and Cemetery (11th to 16th century AD) in ...

Double‐vestibular incision subperiosteal tunnel access (double‐VISTA) with connective tissue graft for treating multiple gingival recessions: 2‐year follow‐up

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Gingival recession has a multifactorial etiology, involving various predisposing and precipitating factors. Non‐carious cervical lesions (NCCLs) are often associated with gingival recession and pose challenges due to their complex pathodynamics.
