Panorametry: suggestion of a method for mandibular measurements on panoramic radiographsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Orthopantomography (panoramic radiography) has been used for the study of measurements involving particularly the prediction of the eruption of impacted lower third molars and analyses of measurements of the ramus and head of mandible. The discrepancies involved with the projection of this radiographic image has stimulated the search for further ways to use it, particularly in orthodontic treatments and oral and maxillofacial surgeries. The author proposes a graphimetric method for the mandible, based on panoramic radiography. The results are expressed in linear and angular measurements, aiming at bilateral comparisons as ...

Mandibular prognathism caused by acromegaly - a surgical orthodontic caseEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
A 22-year-old man presented for orthodontic surgery because of mandibular prognathism. Clinical symptoms suggested acromegaly, and diagnosis was verified by an endocrinologist as well as by radiograph. Bilateral mandibular prognathism often represents the first and most striking physical characteristic of acromegaly; usually, it is also the main reason why patients seek help from orthodontists or maxillo-facial surgeons. This case report recapitulates the clinical and histopathological findings in pituitary growth hormone (GH) adenomas and emphasises their importance in surgical orthodontic planning. Mandibular prognatism,...

A new biphasic osteoinductive calcium composite material with a negative Zeta potential for bone augmentationEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The aim of the present study was to analyze the osteogenic potential of a biphasic calcium composite material (BCC) with a negative surface charge for maxillary sinus floor augmentation. In a 61 year old patient, the BCC material was used in a bilateral sinus floor augmentation procedure. Six months postoperative, a bone sample was taken from the augmented regions before two titanium implants were inserted at each side. We analyzed bone neoformation by histology, bone density by computed tomography, and measured the activity of voltage-activated calcium currents of osteoblasts and surface charge effects. Control orthopanto...

Conclusion: From a clinical point of view, the use of autogenous bone is advantageous if a prosthetic rehabilitation (with functional loading) is expected within 9 months. In other cases the use of anorganic deproteinized bovine bone in combination with autogenous bone seems to be preferable. Donor side morbidity is ignored in this conclusion.

Behavioral changes of patients after orthognathic surgery develop on the basis of the loss of vomeronasal organ : a hypothesisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We introduce a hypothesis which presumes that damage to the vomeronasal organ during a Le Fort I osteotomy of the maxilla for the purpose of orthognathic surgical treatment of congenital or acquired jaw deformities affects the patient's social life in terms of the selection of mates and establishment of relationships. The vomeronasal organ is chemosensory for pheromones, and thus registers unconscious olfactory information which might subsequently act on the limbic system of an individual and influence the selection of mates. We believe it is connected to an inhibitory feedback mechanism which is responsible for the exclus...

Myeloma is characterized by monoclonal bone marrow plasmacytosis, the presence of M-protein in serum and/or in urine and osteolytic bone lesions. HIV-seropositive subjects with myeloma are younger at the time of diagnosis of the tumour and usually the myeloma has a more aggressive clinical course than it does in HIV-seronegative subjects. A case of an HIV-seropositive woman in whom myeloma was diagnosed following progressive swelling of the face, is reported. In addition to bone marrow plasmacytosis and the presence of M-protein in the serum, the patient had an extramedullary lesion affecting the oral cavity, maxilla, paro...

Behavior of osteoblastic cells cultured on titanium and structured zirconia surfacesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Background: Osseointegration is crucial for the long-term success of dental implants and depends on the tissue reaction at the tissue-implant interface. Mechanical properties and biocompatibility make zirconia a suitable material for dental implants, although surface processings are still problematic. The aim of the present study was to compare osteoblast behavior on structured zirconia and titanium surfaces under standardized conditions. Methods: The surface characteristics were determined by scanning electron microscopy (SEM). In primary bovine osteoblasts attachment kinetics, proliferation rate and synthesis of bone-as...

Wegener's granulomatosis (WG) is a multi-system disease, characterised by the triad of necrotising granulomata affecting the upper and lower respiratory tracts, disseminated vasculitis and glomerulonephritis. Oral lesions are associated with up to 50% of cases, although are rare as a presenting feature. The most common oral lesions associated with WG are ulceration and strawberry gingivitis. We review the literature regarding oral manifestations of WG and present a case of lingual infarction, an extremely rare oral lesion associated with WG, in a severe, rapidly progressive and ultimately fatal form of the disease.

The role of apoptosis in early embryonic development of the adenohypophysis in ratsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: We can clearly show an increasing number of apoptotic events only at the basic fusion sides of the adenohypophysis as well as in the opening region of this organ. Apoptotic destruction of epithelial cells at the basal cones of the adenohypophysis begins even before differentiation of the adenohypophyseal cells and their contact with the neurohypophysis. In early stages of development, thus, apoptotic activity of the adenohypophysis is restricted to the basal areas mentioned. In our test animals, the adenohypophysis develops after closure of the anterior neuroporus.

Principles of cartilage tissue engineering in TMJ reconstructionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Diseases and defects of the temporomandibular joint (TMJ), compromising the cartilaginous layer of the condyle, impose a significant treatment challenge. Different regeneration approaches, especially surgical interventions at the TMJ`s cartilage surface, are established treatment methods in maxillofacial surgery but fail to induce a regeneration ad integrum. Cartilage tissue engineering, in contrast, is a newly introduced treatment option in cartilage reconstruction strategies aimed to heal cartilaginous defects. Because cartilage has a limited capacity for intrinsic repair, and even minor lesions or injuries may lead to p...

Penetrating facial injury from angle grinder use: management and preventionEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Injuries resulting from the use of angle grinders are numerous. The most common sites injured are the head and face. The high speed disc of angle grinders does not respect anatomical boundaries or structures and thus the injuries produced can be disfiguring, permanently disabling or even fatal. However, aesthetically pleasing results can be achieved with thorough debridement, resection of wound edges and careful layered functional closure after reduction and fixation of facial bone injuries. A series of penetrating facial wounds associated with angle grinder use are presented and the management and prevention of these injuries discussed.

Obesity and craniofacial variables in subjects with obstructive sleep apnea syndrome: comparisons of cephalometric valuesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
CONCLUSION: The present study found that in non obese as well obese OSAS patients skeletal changes are often evident, especially in obese in terms of intermaxillary divergence, and that, unexpectedly, in obese OSAS patients alterations of oropharyngeal soft tissue are not always present and prevailing.
