Evaluation of the hardness of various foods
Keywords:
food consumption, bite force, masticatory efficiency, occlusal force.Abstract
Objective: evaluate the hardness of various food groups for mastication.
Methods: an in vitro descriptive study was conducted to evaluate the hardness of various tidbits, fried pork rinds and beef using the texture meter EZ-S Shimadzu. Statistical analysis of the data obtained was conducted on an individual basis with Shapiro Wilk and Kruskal-Wallis statistical tests, and Mann Whitney comparison test.
Results: of the food groups studied, the ones standing out for their hardness were the tidbit Coffee Delight® (hard coffee candy) with 268.25 N, followed by another tidbit, Bon Bon Bum® (lollipop) with 179.5 N and mints (hard mint candy) with 165.25 N. Beef and baked donuts exhibited lower values.
Conclusions: due to the intense force that must be applied to fracture and grind very hard food, its consumption constitutes a risk factor for natural teeth and dental restorations alike, since fractures may occur in restorative materials and dental organs.
