  • Title: Development of gingivitis around different types of composite resin.
    Author: van Dijken JW, Sjöström S, Wing K.
    Journal: J Clin Periodontol; 1987 May; 14(5):257-60. PubMed ID: 3301912.
    Abstract:
    Earlier studies have demonstrated signs of gingivitis around conventional composite resin restorations. Newly developed resin types differ considerably in composition and surface characteristics. The purpose of this study was to compare the initiation of gingival inflammation around aged restorations of 3 types of composite resins and around enamel, during a 7-day period of experimental gingivitis. Plaque index, gingival index and crevicular exudate were registered at days 0 and 7. There was significantly less exudate around the intact enamel surfaces than around the composite fillings at both registration times. The plaque and gingival indices showed no significant differences among the composite resins and enamel. The results indicate that differences among the resins with regard to surface roughness and composition did not result in clinically measurable differences in the development of plaque and gingivitis.
