A practice-based evaluation of the handling of a new self-adhesive universal resin luting material

OBJECTIVE: Ease of handling of materials may be considered helpful to achieving good results. The handling properties of a new self-adhesive universal resin luting material were tested in clinical use. METHOD AND MATERIAL: Thirteen practitioners were selected at random from the Product Research and Evaluation by Practitioners (PREP) Panel, a United Kingdom-based group of dental practitioners prepared to complete evaluations of new materials and techniques in the practice environment. Explanatory letters, questionnaires and packs of the luting material were sent to the evaluators. The practitioners were asked to use the material and return the questionnaire. RESULTS: 144 restorations were placed using the new self-adhesive resin luting material, which was rated higher by the evaluators for ease of use (4.7 on a visual analogue scale where 5 represented easy to use and 1 represented difficult to use) than both the pre-trial resin-based and 'conventional' luting materials (rated 3.7 and 4.4 respectively on the same scale). The presentation, instructions, convenience of dispensing and handling and viscosity also received high ratings. CONCLUSION: The new material achieved ratings for ease of use superior to the pre-study resin-based and conventional luting materials in the dental practices of 13 UK dental practitioners.
