OBJECTIVES Since hemostatic agents can induce changes on enamel and dentin surfaces and influence composite resin adhesion, the aim of the present study was to evaluate the effect of the aluminum chloride hemostatic agent on the gingival margin microleakage of class V (Cl V) composite resin restorations bonded with all-in-one adhesive. STUDY DESIGN Cl V cavities were prepared on the buccal su...

Epidermal cell migration is critical for restoration of tissue structure and function after damage. However, the mechanisms by which differentiated cells neighboring the wound sense the wound and assume a motile phenotype remain unclear. Here, we show that Pvr, a receptor tyrosine kinase (RTK) related to platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF) recepto...

High-resolution sedimentological and micropaleontological studies of several deep-sea cores retrieved from the levees of the Celtic and Armorican turbidite systems (Bay of Biscay — North Atlantic Ocean) allow the detection of the major oscillations of the British–Irish Ice Sheet (BIIS) and ‘Fleuve Manche’ palaeoriver discharges over the last 30,000 years, which were mainly triggered by climate ...

Dental materials are essential for most of dental treatment modalities. Understanding the science and chemistry behind their properties can enable operator to employ material its maximum advantage. Contemporary have evolved significantly from conventional variety, but there is always room refinement since inadequacies current in function recognized only with advent advanced testing methods. As ...

Purpose: This qualitative systematic review had two aims: (1) evaluation of the impact of restorative treatment on tooth contour, and (2) investigation of the effect of altered tooth contour on biological health. Methods: An electronic search was conducted using PubMed (MEDLINE), Cochrane Library and Google Scholar. A combination of relevant key words was applied. The search was completed in Oc...

Background—Various factors aVect gastric wound healing. The influence of physical stimulation on gastric mucosal cells during the process of gastric wound healing is not completely understood. Aims—To assess the role of a physical stimulant, in this case mechanical strain, on gastric mucosal restoration. Methods—Mechanical strain was applied to adherent rat gastric mucosal cells (RGM1) cultured...

AIM The aim of this in vitro study was to evaluate and compare the microleakage of restorations using low shrinkage silorane-based dental composite and methacrylate-based dental composites in Class II cavity at the occlusal and gingival margins. MATERIALS AND METHODS Sixty mandibular molars were collected and divided into three experimental groups and one negative control group. Class II slot...

BACKGROUND Pulpal reaction to restorative materials depends on marginal microleakage, which is a dynamic phenomenon that allows bacteria and fluids to traverse across the tooth-restoration interface. Glass-ionomer cement (GIC) exhibits low microleakage due to direct bonding to tooth structures. Hydroxyapatite (HAP) based on the similarity with tooth structure may decrease the microleakage. The ...

BACKGROUND This study aimed to evaluate the microleakage, when flowable composite is used as a restorative material and a liner. MATERIALS AND METHODS Forty, non-carious, extracted human premolar teeth were used and they were divided into five groups according to the type of composite material used. Group I: Hybrid composite was inserted and cured for 40 s. Group II: Flowable resin composite ...
