During the curing shrinkage of adhesively bonded resin composites tensile stresses develop, which are exerted back onto the cavity walls. the extent of the stress determines whether part of the tooth structure will fracture. Unfortunately, shrinkage stress values are not available for the general practitioner. Recommendations are therefore made for the use of low shrinkage and/or low shrinkage stress resin ccomposites for different cavity types. In the current study, thirty resin composites were evaluated for shrinkage and shrinkage stress. The majorityof the composites compplied with the hypothesis that a low shrinkage is accompanied with a high shrinkage stress and visa-versa. Some composite materials showed both a low shrinkage and a low shrinkage stress and are thus proposed to give the least problems with respect to marginal seal and enamel fracture.
