Effect of Myrtus Communis Solution as Denture Cleaning on the Some Properties of Heat Cured Acrylic Denture Base Material

This study was oriented to assess and compare the use of 2% Myrtus communis solution on the dimensional stability, surface roughness and surface hardness of the heat cured resin with 0.12% Chlorhexidine. Ninety samples were fabricated from acrylic resin that cured by water bath, for each test there were three groups according to the type of the immersion. Control group (distilled water); experimental group (0.12% chlorhexidine digluconate solution and 2% Myrtus Communis solution, each group consist from (10) specimens. The surface hardness, roughness and dimensional stability were evaluated for each specimen. The results showed there were no significant differences in the surface hardness, roughness after immersion in all groups, but there was difference in dimensional stability of acrylic resin. As a conclusion the use of 2% Myrtus commnuis solution had no change on the roughness and hardness of resin compared to the chlorhexidine and distilled water, but can cause alterations on the stability of the dimensions of the resin material.
