Evaluation of masticatory performance by image processor

Abstract

Pressure sensitive paper (Prescale) developed color by biting and masticated peanut fragments left on a shieve (10 mesh) were analized by means of image processor with a program “ASPECT”. Using the above mentioned method, biting force of each tooth, occlusal contact area and points and masticatory performance were measured . The correlation coefficient between masticatory performance (Manly' method) and total areas of peanut fragments on the shieve was highest (-0.974). Instead of Manly' method, the image processor analysis could be available for index of masticatory performance.
