title: Research in general dental practice: evaluation of the clinical use of a new composite system by general dental practitioners.
abstract: BACKGROUND
  The purpose of the study was to evaluate a recently introduced aesthetic restorative system in respect of: Presentation and organisation of the package. Its handling characteristics. Its polishability. Shade selection procedures and aesthetic outcome.
  
  
  METHODS
  The material, Esthet.X Micro Matrix system (Dentsply), was evaluated by general dental practitioners from a clinical research group known as PEER (Product and Equipment Evaluation and Research). The evaluators were asked to use the material, following manufacturer's instructions, in a variety of cases. A questionnaire was designed specifically for this study and the questions were directed to both the dentists and their dental nurses. The results were analysed statistically and represented in visual analogue scales.
  
  
  RESULTS
  The material was found to be useful and generally well received. Its use was thought to be technique sensitive but good to excellent results can be achieved. Areas where the evaluators thought the product could be improved were also discussed.
