چکیده

Inadequate force of the cheeks may compromise the tooth positioning and functions such as chewing, swallowing and contribute to aesthetic deformities on the face in humans. In clinical speech-language pathology practice, cheeks force is usually evaluated qualitatively. Perception and practical experience are used to grade them. This paper aims to present a new method for the quantitative evaluation of cheeks force in humans. A prototype was developed based on the principles and tools of Production Engineering Products, and used in the present work. Five individuals were evaluated, ranging between 18 and 35 years old, males, normal with regard to the cheeks force by a perceptual evaluation. The average values of the average force was 5,64 N and the maximum force was 7,76 N. The subjects evaluated demonstrated force values with coefficient of variation considered low (11%). Quantitative evaluation can reduces the subjectivity and increases the probability of proper diagnosis of the cheeks force, especially in cases of slight changes in force, and moreover it is more sensitive for detecting small differences in strength observed with the progression of disease or therapy. The cheek force was quantitatively evaluated through the device developed (which is still in testing phase) and further studies are planned. This device might contribute to the completion the diagnosis process and treatment of changes the structure in question. Proceedings IWBBIO 2014. Granada 7-9 April, 2014 1601

Surface Evaluation of Resin Zein Films Containing Sugar Plasticizers by Permeability and Atomic Force Microscopy Analysis

     Zein is one of the best biopolymer for edible film making and sugars are natural plasticizers for biopolymers. In this research, sugars (fructose, galactose and glucose) at three levels (0.5, 0.7, 1 g/g of zein) were used as plasticizers for zein protein films and their water vapor permeability (WVP), oxygen permeability (OP) and atomic force microscopy (AFM) topography were studied. The p...

Automated classification of optical coherence tomography images for the diagnosis of oral malignancy in the hamster cheek pouch.

Most studies evaluating the potential of optical coherence tomography (OCT) for the diagnosis of oral cancer are based on visual assessment of OCT B-scans by trained experts. Human interpretation of the large pool of data acquired by modern high-speed OCT systems, however, can be cumbersome and extremely time consuming. Development of image analysis methods for automated and quantitative OCT im...

Quantitative force measurements using frequency modulation atomic force microscopy—theoretical foundations

Use of the atomic force microscope (AFM) in quantitative force measurements inherently requires a theoretical framework enabling conversion of the observed deflection properties of the cantilever to an interaction force. In this paper, the theoretical foundations of using frequency modulation atomic force microscopy (FM-AFM) in quantitative force measurements are examined and rigorously elucida...
