The present article aimed to present a standardized protocol for the production of a chewable test material that has been used in masticatory efficiency and performance studies. This chewable material has advantages in respect to its physical properties when compared to other artificial and natural test foods. It is constituted by mixing condensation silicon (58.3% by weight), common plaster (10.2% by weight), alginate (12.5% by weight), solid vaseline (11.5% by weight), tooth paste (7.5% by weight), and catalyst paste (20.8 mg/g), adding also three drops of mint essence. The mixed material is then inserted into an acrylic mould with perforations of 12 mm in diameter and 5 mm in height to produce rounded tablets with those measures after polymerization. It was named 'Optocal - Brazilian version'. A volume of 3 cm(3) is indicated for a chewing test, which corresponds to 12 tablets using the present methodology. The present protocol can make the production of this chewable material easier, helping in its standardization for studies on masticatory function.
本文旨在介绍一种用于咀嚼效率和性能研究的可咀嚼测试材料的标准化生产方案。与其他人工和天然测试食品相比，这种可咀嚼材料在物理性质方面具有优势。它由混合缩合硅（重量占比58.3%）、普通石膏（重量占比10.2%）、藻酸盐（重量占比12.5%）、固体凡士林（重量占比11.5%）、牙膏（重量占比7.5%）和催化剂糊剂（20.8毫克/克）制成，还添加三滴薄荷香精。然后将混合材料插入直径12毫米、高5毫米的带孔丙烯酸模具中，聚合后制成上述尺寸的圆形片剂。它被命名为“Optocal - 巴西版”。咀嚼测试建议使用3立方厘米的量，按照本方法这相当于12片。本方案可使这种可咀嚼材料的生产更简便，有助于将其标准化用于咀嚼功能研究。
