Ariston is a new composite material of white colour indicated for posterior restorations and providing active caries protection. The aim of the present study was to assess the surface appearance of Ariston fillings, marginal adaptation to cavity walls, homogeneity of the filling and the quality of the surface of restorations both clinically and by scanning electron microscopy. A total of 106 re...

OBJECTIVE This experimental in vitro study compared marginal adaptation of indirect composite, glass-ceramic inlays and direct composite. MATERIALS AND METHODS Seventy-five recently extracted human molars were randomly divided into three groups (n=25) and mesio-occluso-distal cavities with the same dimensions were prepared in the teeth. Indirect composite and glass-ceramic inlays were fabrica...

ABSTRACT Purpose: This study evaluated the marginal adaptation and microleakage of ?n-Ceram Alumina, In-Ceram Zirconia Finesse press all-ceramic porcelain systems. Material methods: Thirty maxillary Central teeth extracted for periodontal reasons without caries cracks were divided equally into three group there was no control group; only systems compared. Sample cemented stored in distile water...

Clinical learning in restorative dentistry is principally centred around the provision of patient care, yet we know very little about the learning processes occurring within the clinical environment. A study of undergraduate dental student clinical practice used a combination of group interview and questionnaire techniques to explore some of the characteristics of student/teacher interaction th...

OBJECTIVE The purpose of this study was to determine the effect of two extraoral computer-aided design (CAD) and computer-aided manufacturing (CAM) systems, in comparison with conventional techniques, on the marginal fit of monolithic CAD/CAM lithium disilicate ceramic crowns. STUDY DESIGN This is an in vitro interventional study. PLACE AND DURATION OF STUDY The study was carried out at the...

Local adaptations to environmental conditions are of high ecological importance as they determine distribution ranges and likely affect species responses to climate change. Increased environmental stress (warming, extreme drought) due to climate change in combination with decreased genetic mixing due to isolation may lead to stronger local adaptations of geographically marginal than central pop...
