ANTECEDENTES DE LA INVENCIONBACKGROUND OF THE INVENTION
Actualmente es conocida la importancia de poder evaluar el sistema masticatorio de una persona especialmente en ambientes cllnicos. El estado del sistema masticatorio esta 15 determinado principalmente por el numero y la position de los dientes de la persona que esta realizando la funcion masticatoria. De este modo, se observan distintos grados de anomallas en el sistema masticatorio, siendo especialmente graves para los ancianos.The importance of being able to evaluate a person's masticatory system, especially in clinical settings, is currently known. The state of the masticatory system is determined primarily by the number and position of the teeth of the person performing the masticatory function. In this way, different degrees of anomalies in the masticatory system are observed, being especially serious for the elderly.
El estado del sistema masticatorio puede ser evaluado subjetivamente mediante la 20 autoevaluacion efectuada por la persona que realiza la funcion masticatoria, o bien de manera objetiva mediante estudios cientlficos o cllnicos.The state of the masticatory system can be subjectively evaluated by the self-evaluation carried out by the person performing the masticatory function, or objectively by scientific or scientific studies.
La deteccion de anomallas en el sistema masticatorio se obtiene de forma subjetiva mediante la realization de entrevistas con preguntas sobre su capacidad masticatoria, es decir la 25 capacidad de una persona para moler o triturar un alimento despues de un numero predeterminado de repeticiones.The detection of anomalies in the masticatory system is obtained subjectively by conducting interviews with questions about their chewing capacity, that is, the ability of a person to grind or crush a food after a predetermined number of repetitions.
La evaluation subjetiva del rendimiento masticatorio incluye factores psicologicos que influyen en la respuesta a las preguntas, y por tanto no representan el rendimiento masticatorio real.The subjective evaluation of the masticatory performance includes psychological factors that influence the answer to the questions, and therefore do not represent the actual masticatory performance.
3030
Por otro lado, actualmente tambien son conocidos una amplia variedad de metodos objetivos para detectar anomallas en el sistema masticatorio. La mayorla de estos metodos comprueban el grado de descomposicion, o de fragmentation de un alimento mediante tamizado, o bien mediante el escaneo optico. Es habitual el uso de alimentos naturales, tales como cacahuetes,On the other hand, a wide variety of objective methods for detecting anomalies in the masticatory system are also currently known. Most of these methods verify the degree of decomposition, or fragmentation of a food by sieving, or by optical scanning. The use of natural foods, such as peanuts, is common,
almendras y zanahorias o de materiales sinteticos como el Optosil® de Bayer Dental®.almonds and carrots or synthetic materials such as Optosil® from Bayer Dental®.
Cabe destacar que el uso de materiales sinteticos suele presentar problemas en ciertas personas, que al no estar acostumbradas a esta nueva textura realizan de una forma no 5 habitual la funcion masticatoria.It should be noted that the use of synthetic materials usually presents problems in certain people, who are not accustomed to this new texture in a non-usual way to perform the masticatory function.
En cualquier caso, tanto los alimentos naturales como los materiales sinteticos deben ser fragmentados por la persona y se debe cuantificar el tamano de dicha fragmentation, para calcular el rendimiento masticatorio de la persona y por tanto detectar anomallas en su sistema 10 masticatorio.In any case, both natural foods and synthetic materials must be fragmented by the person and the size of said fragmentation must be quantified, to calculate the person's masticatory performance and therefore detect anomalies in their masticatory system.
Mas concretamente, uno de los problemas mas habituales utilizando tecnicas de tamizado se centra en que los alimentos naturales se disuelven en la saliva. De este modo, realizar el tamizado de un alimento natural masticado se convierte en un procedimiento complicado y 15 largo, pudiendo conducir a errores en la detection de anomallas en el sistema masticatorio debido a dicha disolucion de los alimentos.More specifically, one of the most common problems using screening techniques is that natural foods dissolve in saliva. Thus, sifting a chewed natural food becomes a complicated and lengthy procedure, and can lead to errors in the detection of anomalies in the chewing system due to such dissolution of the food.
En el caso del escaneo optico, son conocidos metodos de escaneo automatico de materiales sinteticos con dos colores tal como la parafina, donde dicho material una vez ha sido masticado 20 permite obtener una imagen en la que se cuentan, mediante un programa informatico, los pixeles de cada color. Este procedimiento requiere de camaras fotograficas de alta resolution y complicadas ecuaciones matematicas realizadas por costosos dispositivos electronicos que son diflciles de implementar en un entorno cllnico.In the case of optical scanning, automatic scanning methods of synthetic materials with two colors such as paraffin are known, where said material once it has been chewed 20 allows to obtain an image in which the pixels are counted, by means of an informatic program, of each colour. This procedure requires high resolution photo cameras and complicated mathematical equations performed by expensive electronic devices that are difficult to implement in a clinical environment.
25 Finalmente, tambien se conoce un metodo de evaluation que consiste en realizar una estimation visual de un chicle previamente masticado y clasificarlo segun una serie de preguntas dentro de la escala Likert compuesta por 5 niveles de respuesta. De este modo, la evaluacion del rendimiento masticatorio depende de la perception visual de la persona que realice la clasificacion.25 Finally, an evaluation method is also known that consists of making a visual estimation of a chewing gum previously and classifying it according to a series of questions within the Likert scale composed of 5 response levels. Thus, the evaluation of the masticatory performance depends on the visual perception of the person making the classification.
