Angesichts des wachsenden Populismus und Rechtsradikalismus ist der Kampf gegen Geschichtsvergessenheit im Denken Handeln wieder höchst aktuell. Auf den ersten Blick scheint - zumindest in Bezug auf die Vormoderne aber kaum vorzuliegen: Mittelalter, Renaissance Frühe Neuzeit erfahren Romanen, Dramen populären Medien einen Boom. Doch auch gerade hier ein aktives An-Denken Simplifizierungen, Myth...

AIM To evaluate the bond strength of one etch-and-rinse adhesive system and one resin-modified glass ionomer cement to sound and eroded enamel. MATERIALS AND METHODS Forty-eight bovine incisors were embedded in acrylic resin and ground to obtain flat buccal enamel surfaces. Half of the specimens were submitted to erosion challenge with pH-cycling model (3x/cola drink for 7 days) to induce ero...

The present study assessed the effects of abrasion, salivary proteins, and measurement angle on the quantification of early dental erosion by the analysis of reflection intensities from enamel. Enamel from 184 caries-free human molars was used for in vitro erosion in citric acid (pH 3.6). Abrasion of the eroded enamel resulted in a 6% to 14% increase in the specular reflection intensity compare...

It is an established assumption that eroded dental hard tissues are particularly prone to toothbrush abrasion. Only a few studies have aimed to show this for dentine and, if so, disregarded the complex histological structure of this tissue. Therefore, the present study sought (i) to investigate the effects of toothbrushing on eroded dentine and (ii) to analyze how the organic matrix influences ...

OBJECTIVE To evaluate the necessity of reconstructing the eroded bony boundaries after mucocele marsupialization when the mucoperiosteum has been spared. STUDY DESIGN Retrospective review of 308 patients treated for a sinonasal mucocele. Of these, 116 showed areas of bone reabsorption in their preoperative computed tomography (CT) scan. METHODS Of 116 patients showing one or more areas of b...
