“…In addition, the group SC, the group SW induced the greatest quantity of cell lysis in 24 h. It may be inferred that the release of cytotoxic substances occurs mainly in the first 24 h, which is consistent with studies (6,9,17) that found an increased release of residual monomers in this period, although it should be noted that on the second day it still showed a lower cell viability in the groups MC, SC and SW compared to the other groups (Table 3). This could have a more relevant negative impact in patients with history of hypersensitivity to acrylic resins (14).…”

“…Residual monomers may alter the final physical properties of resins (10) and induce the arise of local and systemic tissue reactions when in contact with saliva and soft tissues (12), causing hypersensitivity, allergic reactions, cell toxicity (13) and systemic involvements (14).…”

This study evaluated the influence of the manipulation technique and polishing method on the flexural strength and cytotoxicity of acrylic resins. Two manipulation techniques and three polishing methods were used in the fabrication of acrylic plates that were divided into 6 groups (n=10). Groups MM, MC and MW: mass technique with mechanical polishing, chemical polishing and without polishing, respectively; and Groups SM, SC and SW: Saturation technique with mechanical polishing, chemical polishing and without polishing, respectively). Flexural strength was tested in a universal testing machine and the cytotoxicity assay used cell cultures (L-929) for periods of 24 h to 168 h. Flexural strength and cytotoxicity data were assessed using two-way and three-way ANOVA, respectively (a=0.05), followed by post hoc Bonferroni test for multiple comparisons. The effect of combinations of manipulation techniques and polishing methods on flexural strength showed significant differences only between Group SC and Groups MW, MM and MC (p<0.01). Cell viability ranged from 51% (3.9%) to 87,6% (3.2) in the 24-h time interval, and from 87.8% (5.0) to 95.7% (3.1%) in the 168-h time interval. With the increase of cell viability, from the third day (72 h), there was no significant difference among the groups, except between MM and SC (p<0.01) at 72 h. In conclusion, the manipulation technique and polishing method had more influence on the cytotoxicity than on flexural strength.

“…17 A study in 2003 had found that residual monomers in self-cured acrylic resins were higher (up to 4.5%) than in heat-cured acrylic resins (2.2%). 18 In general, the fungus tends to stick to the self-cured acrylic resin rather than to the heat-cured acrylic resin. 5 In vitro study in 2011 also showed that Candida is less attached to heat-cured acrylic resins compared with self-cured acrylic resins.…”
