Aims: to evaluate the effect of three coating materials on the amount of residual monomer leaching from acrylic resin denture base.
Materials and methods: twenty specimens of a heat-cured acrylic resin denture base were prepared at dimensions of 30 x 10 x 1.5 mm length, width and thickness; respectively.
These specimens were divided into four groups: control (in which the denture base left uncoated), monopoly coated, grape seeds oil coated and olive oil coated groups.
For monomer leaching analysis, each specimen was put in a glass tube containing 10 ml of deionized water that was changed daily.
Monomer levels were measured by spectrophotometer at 254 nm, every 24 hour for 7 days analytic period.
The results were ex-pressed as a percentage of leached monomer mass with respect to the weight of specimen.
Results: statisti-cal analysis showed that there was a significant difference in the percentage of residual monomer leaching in uncoated and monopoly coated groups; and insignificant difference in grape and olive oils coated groups.
However, there was a daily decrease in monomer leaching for all groups.
Grape and olive oils coated groups, showed lower leached residual monomer during the whole experimental period than the uncoated and monopoly coated specimens, the daily reduction of monomer leaching was sharp in the un-coated (control) and monopoly coated groups, and it was gradual and slow in oils coated groups.
Conclu-sions: the using of natural oils (grape and olive oils), was more beneficial in reduction of residual monomer leaching, than the resin coating materials (monopoly) in comparison to uncoated acrylic resin denture base.
Key words: Acrylic resin denture base, monomer leaching, coating materials, monopoly, natural oils.
