The effect of plaque control and surgical pocket elimination on the establishment and maintenance of periodontal health. A longitudinal study of periodontal therapy in cases of advanced disease

Abstract: The present clinical study was initiated in 1969 to test the hypothesis that microbial plaque is the cause of periodontal disease and that hence even advanced cases of periodontitis can be cured in patients willing to exercise optimal plaque control. The material consisted of 75 patients with severe destruction of the periodontal tissues. The patients were selected for the study because of their ability to maintain plaque-free dentition. Following an initial examination, a preliminary treatment plan was presented to the patients. This plan included detailed instructions in plaque control measures, scaling, root planning and emergency dental care, including endodontic therapy and extractions. Three to six months after the termination of the so-called presurgical treatment, surgical elimination of pathologically deepened pockets was performed. The patients were recalled every 3 to 6 months after the end of the treatment. At these reexaminations the following parameters were assessed: Plaque Index, Gingival Index, Pocket Depths, Marginal alveolar bone topography and height. The results demonstrate that it is possible to treat periodontal disease successfully, even in advanced stages, in patients willing to maintain plaque-free dentition.

A KInetic Database for Astrochemistry (KIDA)

Abstract: We present a novel chemical database for gas-phase astrochemistry. Named the KInetic Database for Astrochemistry (KIDA), this database consists of gas-phase reactions with rate coefficients and uncertainties that will be vetted to the greatest extent possible. Submissions of measured and calculated rate coefficients are welcome, and will be studied by experts before inclusion into the database. Besides providing kinetic information for the interstellar medium, KIDA is planned to contain such data for planetary atmospheres and for circumstellar envelopes. Each year, a subset of the reactions in the database (kida.uva) will be provided as a network for the simulation of the chemistry of dense interstellar clouds with temperatures between 10 K and 300 K. We also provide a code, named Nahoon, to study the time-dependent gas-phase chemistry of zero-dimensional and one-dimensional interstellar sources.

How Much Do We Care About Absolute Versus Relative Income and Consumption

Abstract: We find, using survey-experimental methods, that most individuals are concerned with both relative income and relative consumption of particular goods. The degree of concern varies in the expected direction depending on the properties of the good. However, contrary to what has been suggested in the previous literature, we find that relative consumption is also important for vacation and insurance, which are typically seen as non-positional goods. Further, absolute consumption is also found to be important for cars and housing, which are widely regarded as highly positional. © 2004 Published by Elsevier B.V.

The Playing Learning Child: Towards a pedagogy of early childhood

Abstract: From children's own perspective, play and learning are not always separate in practices during early years. The purpose of this article is, first, to scrutinise the background and character of early years education in terms of play and learning. Second, to elaborate the findings of several years of research about children's learning in preschool related to the curriculum of early years education and, finally, to propose a sustainable pedagogy for the future, which does not separate play from learning but draws upon the similarities in character in order to promote creativity in future generations. Introducing the notions of act and object of learning and play (by act we mean how children play and learn and with the object we mean what children play and learn) we will chisel out an alternative early childhood education approach, here called developmental pedagogy, based on recent research in the field of play and learning, but also related to earlier approaches to early education.
