Vestibuloplasties with free gingival grafts were performed on 42 teeth in 12 patients exhibiting gingival recession. The tendency toward recurrence was studied after postoperative intervals of 1, 6 and 12 months. The extensions (vestibuloplasties), which were always wider than the transplant, recurred up to the transplantation margin. The transplant itself(More)
SETTING The use of different spirometric definitions for chronic obstructive pulmonary disease (COPD) has made an informative review of the available prevalence surveys impossible. OBJECTIVE To derive adjustment factors that allow the comparison of studies using different spirometric criteria. METHODS Pre- and post-bronchodilator one-second forced(More)
An epidemiological survey was conducted on the cadmium intoxication of 132 residents living on former sewage fields. Besides 'global biological monitoring', the relation between the cadmium secretion in urine and the load of cadmium of the kitchen gardens and flower gardens was analysed.

OBJECTIVE We have previously shown that racial composition of behavioral intervention groups does not affect achieved weight loss. However, it is unclear if the race of the interventionist affects intervention outcomes.

This experimental intervention consisted of instruction and application of an energy psychology intervention, Tapas Acupressure Technique(More)
The effect on marginal inflammation and tooth mobility of occlusal adjustment by grinding was investigated in 43 occlusally traumatized teeth in 29 subjects with gingivitis and marginal periodontitis. The material consisted of 4 groups with tooth mobility of varying degrees of severity, and bone destruction. In all groups increased tooth mobility decreased(More)
