Impact of different oils with single and double layers as separating medium on surface hardness and roughness of tissue surface of acrylic denture base material
Abstract
It is essential to apply a separating medium to prevent the acrylic denture base material from penetrating and adhering to the relatively hard and rough surface of the gypsum mold. The main purpose of this study was to assess and evaluate the influence of four types of oil on the surface hardness and roughness of the base material for acrylic prostheses, to be then compared with one and two layers of cold-mold seal separating media. Sixty-four specimens in total have been collected. Based on the types of separating media utilized in this research, the specimens were divided up into eight groups: cold mold seal one layer (group A), jojoba oil one layer (group B), lemongrass essential oil one layer (group C), linum usitatissimum oil one layer (group D), cold mold seal with two layer (group A1), jojoba oil with two layer (group B1), lemongrass essential oil with two layer (group C1) and linum usitatissimum oil with two layers (group D1). Each group includes eight samples whose surface roughness and hardness have been studied following the processing of the acrylic denture base material. A one-way ANOVA test and an LSD test have been used to analyze the data statistically. Nevertheless, the one- and two-layer cold mold seals do not differ statistically in terms of the surface roughness of the acrylic denture base material. Using a single layer of jojoba oil, followed by one layer of cold mold seal and two layers of cold mold, respectively, produced the best surface hardness of the acrylic denture base material.
