title: Physical and mechanical properties of nystatin-containing denture liners.
abstract: The mechanical and physical effects of the presence of nystatin in three denture liners were investigated. In general, the modified materials were softer, showed greater strain, and demonstrated permanent set under compression for the duration of the tests. However, the degree of change in properties appeared unlikely to lead to reduced clinical performance. The most significant change was a great increase in the equilibrium capacity for water in the case of the modified liners. This may enhance the pharmacologic effectiveness of these liners by encouraging the release of nystatin at the tissue surface. Bacteriologic and clinical studies continue to investigate the possibility that modified semipermanent liners (Coe-Supersoft) may reduce the recurrence of denture stomatitis.
