Posición anormal del disco articular y cambios morfológicos óseos. Hospital de la Policía Nacional de Guayaquil Nº 2. 2012 - 2018.

Abstract

Introduction: Among the most common pr oblems of the temporomandibular joint is disc displacement. Magnetic resonances provide information on the articular disc. Objective: determine that the abnormal position of the articular disc causes morphological bone changes of the mandibular condyle and the articular eminence. Materials and methods: an image-based, descriptive non-experimental retrospective study. 103 magnetic resonances of patients 12 years and older, between the years 2012 to 2018; they were observed and analyzed. Results: It was found that in; Articular disc; Category 1: 67 patients (65%). Category 2: 23 patients (22%). Category 3: 5 patients (5%). Category 4: 2 patients (2%). Category 5: 2 people (2%). Mandibular condylar; normal: 85 patients (83%); flattened: 13 patients (13%); erosion and osteophyte: each of them in a different patient (1% respectively). Joint Eminence; Aplanada: 12 patients (12%); sigmoid with 66 patients (64%); box: 20 patients (19%); and deformed: 2 patients (2%). Discussion: Nebbe agrees that disc displacement is more common in women. Barrera found affected patients between an age range of 27 to 59 years of age, similar to our study. Kurita was not agreed on the articular eminence since a relation with disc displacements and the box shape was found in 19% of the sample. Mandibular condylar: 85 patients presented normality, which does not coincide with the article by Matthew C. et al; since it is related to the morphological changes of both the mandibular condyle and the articular disc. Conclusion: Null hypothesis was denied since there is no relationship between disc and bone changes, however there is no significant difference (value p> 5% 0.05) that affirms this relationship between the articular disc and bone changes.
