BACKGROUND Contrary to the situation for amalgam restorations, obtaining acceptable proximal contacts with posterior composite restorations can be difficult. Proximal contacts that are less than ideal may permit food impaction and subsequent caries formation and periodontal problems. PURPOSE The aim of this study was to assess the quality of proximal contacts of posterior composite restoratio...

BACKGROUND Long-term prospective survival studies of resin-modified glass ionomer cements (RMGICs) and polyacid-modified resin composites (compomers) placed in non-carious cervical lesions (NCCLs) are lacking from general dental practice. Short-term studies have shown an unsatisfactory clinical performance for several materials. METHODS One practitioner placed 87 compomer (Compoglass, Vivaden...

UNLABELLED Toothwear is increasing in prevalence. Traditional treatment methods for moderate or advanced toothwear, such as indirect restorations and crown lengthening surgery, are invasive and destructive of remaining tissues. The 'Dahl technique' has been used to obtain space for anterior restorations and has been modified such that direct composite restorations are placed at increased occlus...

Research has shown that overhanging dental restorations and subgingival margin placement play an important role in providing an ecologic niche for periodontal pathogens. Periodontal attachment loss and inflammation associated with overhanging restorations were reported extensively in the literature. A total of 15 overhanging amalgam restorations were selected and the plaque index (PI), Gingival...

The gathering of clinical data on fractures of dental restorations through prospective clinical trials is a labor- and time-consuming enterprise. Here, we propose an unconventional approach for collecting large datasets, from which clinical information on indirect restorations can be retrospectively analyzed. The authors accessed the database of an industry-scale machining center in Germany and...

OBJECTIVES To investigate in a prospective follow up the longevity of posterior resin composites (RC) placed in permanent teeth of children and adolescents attending Public Dental Health Service. METHODS All posterior RC placed, in the PDHS clinics in the cities of Copenhagen and Frederiksberg in Denmark between November 1998 and December 2002, in permanent teeth of children and adolescents u...

AIM This was to investigate if dental restorations on human, dog and bovine primary teeth are equitable for microleakage analysis, and the respective marginal adaptation deficiency in in vitro conditions. MATERIALS AND METHODS In order to determine the level of microleakage in Class V poly acid-modified composite restorations of human, dog and bovine primary teeth, samples were evaluated by d...

STATEMENT OF PROBLEM Little information is available about the buccal gingival level of multiple implant restorations. PURPOSE This study was aimed to evaluate the relationship between width and height of buccal soft tissue around single and 2 adjacent implant restorations. MATERIAL AND METHODS Four implant restoration groups (first and second molars, single second molars, posterior single ...

In this article, we report on the evolution of a series of dental outreach missions sponsored by Stony Brook University to remote areas of Madagascar over a nine-year period. The project evolved from one dental resident performing only dental extractions in 1999 to a team comprised of two dentists, six third-year dental students, and two dental assistants performing dental restorations, extract...
