Evaluation of a novel compule-based gingival retraction system in UK general dental practices

Twelve members were selected at random from the PREP panel, a group of UK-based dentists who are prepared to carry out research in their practices. A questionnaire was designed to determine the views of the participants, who were asked to use the retraction paste capsules where clinically indicated. They were asked to return the questionnaire after 8 weeks and the information contained therein was collated and presented mainly on visual analogue scales (VAS). A total of 160 impressions were taken using the Astringent Retraction Paste (3M ESPE, Seefeld, Germany) plus use in the placement of 25 restorations. Of evaluators, 83% (n = 10) agreed that Astringent Retraction Paste was a suitable product for gingival retraction and 75% (n = 9) agreed that it had good haemostatic properties. Overall dispensing and handling of the paste was rated as 4.9 on a VAS scale where 1 = Inconvenient and 5 = Convenient. The viscosity of the paste was rated as 3.6 on a VAS where 1 = too thin and 5 = too thick. Good scores were...
