Abstract

Pre-warming of traditional composites enhanced their flow but they were still 'not as flowable as flowable composites', when the latter were at ambient temperature.

When compared with traditional composites, flowable composites have been shown to have improved marginal sealing properties although generally 'there is little clinical evidence to indicate their clear benefits.' The aims of this in vitro study were to determine if pre-warming composites (four traditional composites, one compomer and one flowable composite) improved their 'flow observed by measuring film thickness', but not have other adverse biological or physical properties (latter not reported in this abstract). At 60°C, traditional composites did not result in them having similar flowable properties as flowable composite at ambient temperature. Pre-heating did not influence their cytocompatibility, although this characteristic varied between materials.
