summary The articular disc of the temporomandibular joint was studied in a foetuses and children group (GI), a dentate group of adults (GII) and an edentulous, elderly group of humans (GIII) by light microscopy. The main, constituent bundles of type I collagen fibres are stratified and are orientated sagittally, transversely and obliquely in the middle portion of the disc. In the thick, posterior portion, transverse bundles constitute the main feature. In the anterior portion of the disc, the fibres are sagittally and obliquely orientated. Type III collagen fibres, intermingled with type I collagen fibres are present in all groups. The disc is cellular in nature in foetuses and children, becoming more fibrous with age. Chondroid cells are observed in all portions of the discs in groups GII and GIII. Elastic fibres are numerous in GI discs and decrease in number in the disc with age. These fibres lie parallel to the collagen fibres in all three portions of the three groups.

“…With these characteristics, the disc can be in tight contact with the articular surfaces of condyle and fossa during joint movements, which is important for maintaining normal TMJ function. 12,13 Kurita et al 14 reported that a frequently found characteristic of TMJ discs that had been surgically removed from TMD patients was that they were thicker than normal. An increased thickness may reflect a change in functional demand or may be the result of pathology.…”

Objectives:To test the hypothesis that experimentally created physiologically nonbalanced occlusion will not affect the thickness of the temporomandibular joint (TMJ) discs in rats. Material and Methods: Twenty-four 8-week-old Sprague-Dawley rats were equally divided into a control group that was left untreated and an experimental group where a nonbalanced occlusion was created. Elastic rubber bands, 1 mm in diameter, were inserted and 1 week later were replaced by plastic material between the first and the second molars of the left maxillary and the right mandibular dentitions to move the first molars about 0.8 mm mesially. This created and maintained a physiologically nonbalanced occlusion. The animals were euthanized 8 weeks later, and the TMJ disc thickness was measured on histologically prepared slices using an electronic meter. Two-way univariate analysis of variance was used to compare the groups (␣ level ϭ .05). Results:The intermediate zone was thicker in the experimental group than in the control group (P ϭ .003), but no differences were found between groups regarding the anterior and posterior bands. There were no significant sex-related effects on this observation. Conclusion:The hypothesis is rejected. The results indicate that the intermediate zone of rat TMJ disc has the ability to adapt to the alteration of the space between condyle and fossa caused by occlusion changes. Further studies on larger groups that are followed for longer times are needed. (Angle Orthod. 2009;79:51-53.)

Mandibular subluxation stabilized by mouthpiece for distal internal carotid artery exposure in carotid endarterectomy

The standard approach for carotid endarterectomy cannot provide adequate exposure of the distal internal carotid artery in the presence of high cervical carotid bifurcation or high plaque. Limited accessibility of the distal internal carotid artery has resulted in the development of various operative techniques. Mandibular subluxation is the most simple and least invasive technique, but it does require invasive maneuvers, such as wiring, to stabilize the mandible. We use a mouthpiece made by the dentist to stabilize the mandible in the physiologic subluxated position. This technique provides an adequate exposure of the distal internal carotid artery as with the other methods, and the risk of morbidity is very low.
