Cystatins are inhibitors of cysteine proteinases and could play a protective and regulatory role under inflammatory conditions. Since total cystatin activity of whole saliva was increased in periodontal patients (Henskens et al., 1993), we wanted to investigate the types or origins of cystatins involved in this increase. Distinct types of cystatins were(More)
BACKGROUND Laparoscopy training has become an integral part of surgical education. Suturing and knot tying is a basic, yet inherent part of many laparoscopic operations, and should be mastered prior to operating on patients. One common and standardized suturing technique is the C-loop technique. In the standard training setting, on a box trainer, the(More)
The objectives of the present study were to establish in a long-term investigation the safety as well as the clinical and microbiological efficacy of scaling and rootplaning combined with local application of 2% minocycline hydrochloride-gel versus placebo-gel in patients with moderate to severe chronic adult periodontitis. This was an 18 months,(More)
The purpose of this study was to evaluate the safety and efficacy of the Braun Plak Control for the removal of supragingival plaque and improving gingival health in a long-term clinical trial, and to compare it to regular manual toothbrush. Assessed were plaque accumulation, amount of gingival inflammation, gingival bleeding on probing, and calculus. In(More)
The purpose of the present study was to establish in vitro the inhibiting effect of a herbal extract mixture on a selected number of micro-organisms and to test in vivo the effect of a mouthwash containing 6.3 mg/ml herbal extract mixture on plaque and gingivitis as compared to a minus active control mouthrinse. The herbal extract was a mixture of:(More)
The purpose of the present study was to evaluate the effect of an electronic toothbrush on established plaque and gingivitis in a 5-month clinical trial. This electronic toothbrush sends approximately a 0.15 mA current through the brushhead which presumedly enhances the efficacy of the brush in plaque elimination. For this study, 80 volunteers (non-dental(More)
INTRODUCTION Intracorporal knot tying (ICKT) and suturing in minimal invasive surgery (MIS) represent a key skill for advanced procedures such as Nissen fundoplication. Suture placement under tension is particularly challenging during MIS. The aim of this study was to compare ICKT of the common surgical square knot and the slipping knot on a simulated(More)
Learning curves for minimally invasive surgery are prolonged since psychomotor skills and visuospatial orientation differ from open surgery and must be learned. This study explored potential advantages of sequential learning of psychomotor and visuospatial skills for laparoscopic suturing and knot tying compared to simultaneous learning.
