Tissue reactions to polycarboxylate cements

Journal of Endodontics, 1976
Root canals of the teeth of two dogs were filled with polycarboxylate cements, with and without additives. After 120 to 225 days, histologic examination showed the presence of severe, persistent inflammatory lesions around the materials. The results indicated that there would be no advantages to using polycarboxylates as root canal filling materials.
