ABSTRACT
BACKGROUND:
During physiological function of the temporomandibular joint, we have to rely only on elastic structures (in particular the bilaminar zone) for repositioning of the articular disc. A real muscle, however, would be functionally more reasonable. In patients, a decrease of this elasticity is possibly one of the reasons for temporomandibular joint malfunctions, which affect between 16% and 36% of the population.METHOD:
This study assesses the morphogenesis of the murine (Mus musculus) temporomandibular joint with particular regard to the masticatory muscles, to throw light on this topic. To that end, a collection of 11 murine heads ranging from prenatal stages E13.25 to E20 was used and early postnatal stages P0 to P4, which were prepared as histological sections (thickness 8-10 µm) and stained conventionally in order to examine them with light microscopy. Next, the temporomandibular joint and selected surrounding structures, along with the masticatory muscles, were threedimensionally reconstructed using analySIS® software. Subsequently, specific morphometric analyses were performed. RESULTS ANDCONCLUSIONS:
The evaluation of the results led to the following conclusions.Palabras clave
