Evaluation of four elastomeric interocclusal recording materials

Background: The fabrication of dental prosthesis requires the transfer of interocclusal records from patient's mouth to semiadjustable articulators using different kinds of recording media. Any inaccuracy in these interocclusal records leads to occlusal errors in the final prosthesis. This study was conducted to evaluate the dimensional changes occurring in the interocclusal recording material over a given period of time and the material's resistance to compression during the cast mounting on the articulator.     

New health promotion indicators: the general health policy model

This article provides an overview of a general health policymodel and associated measures of health status. It describessome pervasive issues in health measurement, the applicationsof the model in screening, prevention and in tertiary care anddiscusses the studies of cost-benefit and cost-utility in policyanalysis. The author gives examples from primary, secondaryand tertiary prevention studies that suggest the general applicabilityof the model and argues that a general health policy model canbe used to quantify the health effects of health promotion.
