Vegetable ash as raw material in the production of glasses and enamels, for example the contemporary vegetable ashes from Burgundy, France [PDF]

open access: yesarXiv, 2010
The powdery nature and high alkali content of vegetable ashes make them ideal raw materials to be used as modifiers of silicate compositions (glasses, enamels and ceramics). Their utilisation since ancient times is described in the literature of the history of glasses, but studies on the analyses of their composition are still limited.

Experimental Combat-Stress Model in Rats: Histological Examination of Effects of Amelogenesis-A Possible Measure of Diminished Vagal Tone Episodes [PDF]

open access: yes, 2004
Developmental defects of enamel-stress histomarker rings (accentuated striae) may be a potential measure of diminished vagal tone in research on extreme stress such as exposure to combat.

Design of quantum correlation based automatic focus detection system during dental laser operation [PDF]

open access: yesarXiv, 2019
Dental laser has been developed recently and gradually replaced the conventional dental treatment methods, especially in dental caries removal. The utility of laser in dentistry contributes to reduce the pain during surgery and decrease the risk of sequelae after surgery.

How do children with amelogenesis imperfecta feel about their teeth? [PDF]

open access: yes, 2014
Amelogenesis imperfecta (AI) is an inherited dental condition affecting enamel, which can result in significant tooth discolouration and enamel breakdown, requiring lifelong dental care.

ToF-SIMS Investigations on Dental Implant Materials and Adsorbed Protein Films [PDF]

open access: yesarXiv, 2011
In this work the two experimental dental implant materials FAT and FAW, made of fluoroapatite particles embedded in polymer matrices, and films of the proteins lysozyme, amylase and bovine serum albumin (BSA), adsorbed to the two dental implant materials, were investigated with time-of-flight secondary ion mass spectrometry (ToF-SIMS) and the ...

Near-infrared imaging of demineralization on the occlusal surfaces of teeth without the interference of stains. [PDF]

open access: yes, 2019
Most new caries lesions are found in the pits and fissures of the occlusal surface. Radiographs have extremely low sensitivity for early occlusal decay, and by the time the lesion is severe enough to appear on a radiograph, it typically has penetrated ...

Survival analysis of fragment reattachments and direct composite restorations in permanent teeth after dental traumatic injuries

open access: yesDental Traumatology, Volume 39, Issue 1, Page 49-56, February 2023., 2023
Abstract Background/Aim In case of crown fractures after traumatic dental injuries, the affected teeth can be restored either with reattachment of the fractured fragment or with a direct composite restoration. So far, longevity data for reattachments and direct composite restorations with regard to different failure types (pulp necrosis and infection ...
