“…Optosil tablets (5 mm thick, 20 mm diameter) (Optosil P Plus; Heraeus Kulzer, Hanau, Germany) were made as described by Albert et al 15 and were cut into four quarters. Two types of chewing test food were used: three quarter tablets (2 g) without a bag (unbagged silicon) and three quarter tablets placed in a latex bag which was sealed with cyanoacrylate adhesive (bagged silicon).…”

“…14 Consequently, the use of artificial test foods such as silicon impression material is Page 5 of 20 A c c e p t e d M a n u s c r i p t 5 reliable. 15 It has been shown that tough and hard foods, as well as materials with high cohesiveness that do not disintegrate are more appropriate to determine the PCS. 9.16-18 Real food placed in a latex bag has also been used to assess the masticatory function.…”

Highlights:There is a positive association between the preferred chewing side and the more efficient side Alternate unilateral chewers masticate more efficiently than consistent unilateral chewers.Alternate unilateral chewers can masticate as or more efficiently when they chew unilaterally.Page 2 of 20 Objective: This study assessed the degree of relationship between masticatory laterality and lateral asymmetry of masticatory performance using silicon pieces enclosed in a latex bag.Design: Forty-two young adults with natural dentition participated in this crosssectional, observational study. They performed four different masticatory assays, each consisting of five trials of chewing three pieces of silicon for 20 cycles. In one assay, they were asked to masticate unbagged silicon free-style, whilst in the three other assays they were asked to masticate bagged silicon free-style, unilaterally on the right-hand side and unilaterally on the left-hand side. The preferred chewing side was determined by calculating the asymmetry index for both the free-style assays. Masticatory performance was determined by sieving the silicon particles and the cycle duration was also recorded. Data were analysed using independent samples or paired t-test and linear regression.Results: Masticatory function using the bagged silicon was similar to that using the unbagged silicon. A significant and positive relationship was observed between the preferred chewing side expressed as the asymmetry index and the side with better masticatory performance. Alternate unilateral chewers demonstrated better masticatory performance than unilateral chewers. However, when free-style and unilateral chewing were compared for each subject, unilateral chewing was found to be as efficient as -or even more efficient than -free-style chewing.Page 4 of 20 A c c e p t e d M a n u s c r i p t 4 Conclusions: There is a positive association between the preferred chewing side and the more efficient side. Alternate unilateral mastication per se does not promote better masticatory performance than consistently unilateral mastication.

“…5,[11][12][13] Condensation silicone has been used in masticatory tests with excellent results. 4,[14][15][16][17][18] The silicone samples fulfill all the criteria of a test material. Namely, it is stable, accurate, reproducible, and has mechanical properties that are comparable with those of natural food substances.…”

“…Namely, it is stable, accurate, reproducible, and has mechanical properties that are comparable with those of natural food substances. 14,15 The test materials do not dissolve in water or saliva and can be broken down during mastication. They do not break along predetermined fault lines and have no taste.…”

“…Otherwise, silicone samples may be masticated in a way which is similar to how a natural food is maticated. 14,15 Optosil  has been largely applied, but it is a material with a fracture strength that is too high in comparison to the maximum bite force of subjects with compromised oral conditions, such as denture wearers. Consequently, an experimental chewable material (Optocal), having Optosil NF  as a base and mixed with other components was developed and its force-deformation properties were compared with those of Optosil  .…”

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 cm³ 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.
