Dentine dysplasia type II is an autosomal dominant disorder in which mineralization of the dentine of the primary teeth is abnormal. On the basis of the phenotypic overlap between, and shared chromosomal location with, dentinogenesis imperfecta type II, a second disorder of dentine mineralization, it has been proposed that the two conditions are allelic. As recent studies have shown that dentin...

background: candida albicans (c. albicans) may have cariogenic potential but its role in caries etiology has not been established. the aim of this study was to determine c. albicans in supragingival dental plaque and infected dentine of cervical and proximal in early childhood caries (ecc). methods: this cross-sectional study was carried out on 6o children aged 2-5 years, which were divided int...

Introduction: Effect of zinc oxide-eugenol (ZO-E) on bond strength of composite is equivocal. The aim of the present study was to determine if ZO-E affects shear bond strength. Methods: For the purposes of the study, extracted human molar teeth were ground so thatcomposite rods could be bonded to dentine. In group 1, dentine was not exposed to ZO-E. In group 2,...

The effects of different doses of Ukrain and/or strontium on the rat teeth intertubular dentine were analysed in cuts perpendicular to the dentinal tubes. To the dentine elemental analysis, scanning electron microscopy (SEM) equipped in XRF (X-ray fluorescence) microprobe was used. Strontium concentration increased from 4.1% in the control group to 5.0% and 6.3% for the groups administered with...

Abstract Fissure caries in a form of brown spot lesion is serious problem for patients. Having passed the dentine-enamel junction, cariogenic bacteria cause demineralization dentine its vicinity. Over time, area spreads deeper towards pulp tooth, creating gradient strength characteristics dentine. The aim this work was to determine mechanical properties and mineral density direction from juncti...

OBJECTIVE This study tested the hypothesis that the use of ethylenediamine tetraacetic acid (EDTA) as a final irrigant causes canal wall erosion only after prolonged use of 5.25% sodium hypochlorite (NaOCl) as the initial irrigant. METHODS Two irrigation protocols were employed: (1) 5.25% NaOCl as the initial irrigant for 10 min and 17% EDTA as the final irrigant for 2 min; and (2) 5.25% NaOC...

Several reports have indicated that resin bond strengths to noncarious sclerotic cervical dentine are lower than bonds made to normal dentine. This is thought to be due to tubule occlusion by mineral salts, preventing resin tag formation. The purpose of this review was to critically examine what is known about the structure of this type of dentine. Recent transmission electron microscopy reveal...

This study aimed to review the laboratory methods on biomimetic remineralization of demineralized human dentine. A systematic search of the publications in the PubMed, TRIP, and Web of Science databases was performed. Titles and abstracts of initially identified publications were screened. Clinical trials, reviews, non-English articles, resin-dentine interface studies, hybrid layer studies, hyb...

OBJECTIVES To evaluate the influence of dentine on the pH of different medications in standardized simulated canals. MATERIALS AND METHODS Forty resin blocks were divided into groups with and without dentine powder, as follows: 2% chlorhexidine gel; 2% chlorhexidine gel associated with calcium hydroxide PA; calcium hydroxide PA delivered in propylene glycol 600; and NPG delivered in distilled...
