RESUMO

The aim of this study was to analyze histological and histomorphometrical features of the articular disc in groups with and without disc displacement. A convenience sample of 39 temporomandibular joints (number of case specimens: 31; number of control specimens: 8) from 28 patients (mean age 31.2) were recruited for study. The patients were considered affected and treated surgically with disc repositioning when presenting painful clinical signs of disc displacement, after unsuccessful nonsurgical treatment for at least six months. The posterior region of the disc was removed and submitted to histological (hematoxylin-eosin) and histomorphometrical (Picrosirius method) analysis. Statistically significant differences among the analyzed groups were accessed through the qui-square test (p ≤ 0.05). The U of Mann-Whitney test was used to observe the differences among mean values when variables did not present normal distribution [Kolmogorov-Smirnov(a) test]. To the limit of this study, there were no significant structural differences in the collagenous extracellular matrix in the articular disc among groups with and without TMJ disfunction.
