Masticatory muscle disorder group reported the higest mean ages(p<0.01), the short CC duration, steady inclosing C.C and the long duration of pain. The pain was frequently increased on chewing occasion and showed the highest value of MMPI(p<0.01). 2. Internal derangetment groups reported lower mean age and lower value of MMPI. While ID+R group reported the short duration of pain and more frequent incidences of clickings related with wide opening(p<0.01). But in ID-R groups, most frequent incidences of female and brutism were observed and they frequently showed clicking and locking events related with hard food chewing. 3. Mixed group reported the frequent incidences of tole response onto MMPI and the mixed type of characteristics between M and ID+R, ID-R groups were found in this group. 4. Painless clicking group reported the youngest mean age(p<0.01) and the long duration of C.C (p<0.01), the slowly increasing pattern of C.C, and showed lower incidences of responded MMPI. 5. Osteoarthritis group showed the old mean age and reported the pain first rather than the TMJ noise. And they revealed the slowly increasing pattern of C.C and the long duration of CC, and the longest pain duration(p<0.01). Occlusal changes (the loss of posterior molar support, the decrease of CO stops) were frequently observed(p<0.05). And revealed high values of responded MMPI. 6. Arthralgia group showed the lowest incidence of female( p<0.01) and the short duration of C.C and the symptoms were slowly increased, and the value of responded MMPI were low. According to tole above results, there were a lot of differences in characteristics of various sign and symptoms, and many factors involved in different TMD TMD diagnostic subgroups in spite of imcomplete homogeneity. It seemed to be possible to see the characteristics of TMD patients correctly if the diagnostic subgroupings were used in TMD diagnosis and treatmentrestrictio

[์˜๋ฌธ] The establishment of an optimal and functional condylar position (centric relation) as the therapeutic and diagnostic reference position during occlusal treatment for patients with temporomandibular joint and muscle pain dysfunction has long been an important subject in dentistry. The objective of this study was to compare the reproducibility and the changes of condylar position in normal group to those in patient group after use of the occlusal biteplane splint. For this study, 11 normal adults who had no symptoms of masticatory dysfunction and 18patients who had visited at the department of occlusion in dental infirmary of Yonsei University were selected. For each subject three centric relation records were recorded before treatment, after 2 weeks and after symptoms were improved. And the condylar positions in centric relation were measured using articulators and a Vericheck. On the basis of this study, the following results were obtained. 1. In normal group, there was no significant difference of reproducibility in condylar position before and after the use of the occlusal biteplane splint for 2 weeks. 2. In patient group there was significant improvement in the reproducibility of condylar position after treatment (P < 0.71). The reproducibility in patient group, however, was less than normal group.(P < 0.01) 3. The mean distance of condylar movements was 0.38 ยฑ 0.22 mm after 2 weeks in normal group. 4. In patient group, condylar movements were 1.36 ยฑ 0.70 mm (P < 0.01), significantly different from normal group. (P < 0.01) 5. In patient group, the main direction of condylar movements after treatment was toward anterior and superior, preponderance being at superior direction.prohibitio

    Un Cuestionamiento sobre la Estructura Social de los Mayas Prehispรกnicos y su Interpretaciรณn Predominante

    Hasta el momento, varias investigaciones dicen que tanto los nobles" como los plebeyos" vivieron en diversos lugares de las zonas urbanas y rurales, habiendo una gran dicotomรญa en los niveles de espacio que ocupaban las viviendas de los diferentes estratos sociales. El espacio tambiรฉn se relaciona con las concentraciones del poder. En la actualidad el modelo: noble-rico-poder-concentrado en el centro de la ciudad, y plebeyo-pobre-no poder-concentrado en la periferia de la ciudad, es aun la visiรณn dominante. Sin embargo, las fuentes histรณricas nos revelan que el poder polรญtico, econรณmico y social de los mayas surge desde las unidades familiares. La familias extensas forman otros elementos polรญticos mรกs grandes, bajo un sistema parecido a una alianza 0 confederaciรณn de estas unidades sociales bรกsicas. Pero, a pesar de la formaciรณn de estos grandes conglomerados, el sistema de familia nunca perdiรณ su lugar predominante en la sociedad Maya. Por 10 tanto, reiteramos a la familia" como el elemento esencial para la comprensiรณn del mundo de la sociedad maya prehispรกnica. Todas las familias forman p๋”ฐte de agrupamientos mayores, en los cuales habรญan lรญderes elegidos entre quienes representaban los intereses de las familias. A pesar de la existencia de otras agrupaciones polรญticas de mayor dimensiรณn (batabil, cuchcabal), ellas mantenรญan, los beneficios de sus componentes. Asรญ que todas las familias tenรญan su importancia y no existรญa un grupo sociopolรญtico de mayor poder sobre los demรกs, que controlara estrictamente a los que estaban bajo su dominio. A su vez, el sentido de gobemar no estaba basado en la superioridad e inferioridad entre gobemantes y gobemados, sino que era una coordinaciรณn mutua para mantener a la comunidad en armonรญa. El poder polรญtico nace desde una relaciรณn parental, a travรฉs de cierto sistema de elecciรณn, y del papel de los consejeros altamente desarr์ดlados. Teniendo estas posibilidades los ambientes acadรฉmicos de los estudios Mayas repiten el modelo concรฉntrico. Esto sugiere algunas inquietudes. Primero en muchas ocasiones los fenรณmenos sociales requieren diferentes formas de interpretaciรณn para ์—†npliar su comprensiรณn. Ya que la existencia รบnica de un sรณlo modelo tendrรญa un estricto lรญmite acadรฉmico. Por otro lado, las situaciones del Posclรกsico tardรญo 0 el momento del contacto es la parte mรกs importante para reconstruir las caracterรญsticas de la Civilizaciรณn de los Mayas. Sin embargo no tomar en cuenta la informaciรณn de este perรญodo serรญa imprudente. Con la excepciรณn de los perรญodos de apogeo del Clรกsico y Postclรกsico, los demรกs perรญodos no mantenรญan un poder concรฉntrico, asรญ que el modelo que revisamos aquรญ, 0 sea el modelo desconcรฉnฯ€ico del Postclรกsico tardรญo, serรญa mรกs familiar para entender la realidad socio-polรญtica de esos perรญodos. Si se toma en cuenta que este modelo desconcรฉntrico no es totalmente รบtil como un modelo fundamental para entender el mecanismo socio-polรญtico maya, aun serรญa valioso para comprender la funciรณn y el papel de la gente comรบn. Asรญ es una tarea que se extiende de este modelo hasta los otros perรญodos de la civilizaciรณn maya incluyendo la etapa del รบltimo desarollo del Clรกsico y Postclรกsico con ciertas modificaciones
