[Comparative study of two light cured composite resin for closing the median diastema "one year study"].

Abstract

Median diastema in twenty patients aged 17-30 years old were restored randomly with two light cured composite resins. The restoration were assessed and compared after one year for colour changing, gingival inflammation, surface chipping and lost of restorative materials. There have no difference in colour changing of the two materials on the tooth surface (p = 0.01), and there have no difference in the inflammation of the gingiva surrounding the two materials (p = 0.01). These two materials have no difference in adhering to the tooth surface (p = 0.01).
