Epistasis refers to a gene (or genes) of one pair masking the expression of a gene (or genes) at a different locus. Dominance refers to the form of expression of a gene in relation to its allele (or alleles). When an allele is dominant, the heterozygous combination is the same phenotypically as one of the homozygotes. Epistasis is a nonallelic interaction; dominance is an allelic interaction.
