Thirty-three patients, 7-13 years of age, demonstrated 96 pairs of contralateral occlusal fissure a_~d buccal and lingual pit cavities which were restored with a high-copper amMgam. One restoration of each pair was polished with a slurry of XXX Silex in an unwebbed rubber cup at eight minutes following trituration. The contralateral restoration was finished at least 24 hours after iasertion wit...
