The study of 40 cases of voluminous odontogenic cysts has made evident the general characteristics of these current odontogenic tumors always tied-in with a tooth without any pathognomonic sign. The diagnosis is made by reasoning, combining clinical information, age, localisation, development, x-ray's information and anatomo-pathological parameters. The treatment is surgical enucleation of the cyst and it's generally easy.
Glossodynias are a build up of painful lingual syndromes with neither a detectable visible lesion, nor of a known organic origin. An obvious discordance between the subjective feelings and the weakness, even absence of an objective lesion support able to explain them, can be observed. Being often considered by physicians to be of a psychological origin, they are always the object of never-ending research for a detectable lesion which would explain their complications. Following consultations with 114 patients in the department of Stomatology, and in collaboration with our neuropsychiatrist colleagues in the same hospital, we took stock of this frequent application which bothers the buccal specialist, who does not know to consider it or how to treat it.
Dental pains provoked by an altitude beyond 5.000 ft can occur with any kind of tooth, healthy or restored. It is considered as a consequence of a brutal pressure change. The incidence has not been decreasing in spite of flight conditions improvement. These kind of dental pain cause a problem for those who fly: civilian and military pilots as well as airlines passengers. The conditions in which this might happened are variable. There may be a definite correlation between the character of the symptoms of aerodontalgia and the underlying pulpal pathology. The proposed etiology concerning pathological teeth is an oedema and hyperthermia of the pulp which can lead to necrosis. In an indirect type dental pain is secondary to stimulation of the superior alveolar nerves by a maxillary barosinusitis, or anatomic malformation. The most frequent is a pain during ascent (decompression), and the most concerned teeth are upper molars. The preventive treatment is very important. Both complete clinical and radiological examinations must be achieved. Regular dental examination are-essential for the crew. Aerodontalgia can be largely prevented by high quality root and dental cares. The case of a 26 years old man who use to suffer for a long time of dental pain during flights is in accordance with the dominant clinical symptoms of this affection.
544 cases analysis have shown that the sagittal maxillo-mandibular discrepancies happens to be a very frequent problem in orthodontics. They are often compensated by dento-alveolar inclinations, when no muscular disorder, functional or constitutional, exists. The basal discrepancies modify the direction of dental inclinations. It is the normal action of the musculature which determines the correctional inclination that must be respected. We have to use light therapeutic methods and respect these natural dental movements.
The authors have studied the localization, the functional and radiological signs, the complications, the etiologies and the treatment, according to 212 cases of impacted canines. The upper impacted canines are more frequent and women are more concerned, it can be unilateral as well as bilateral. If the mentioned etiologies are debatable and if the functional signs are poor, the complications are frequent: infectious, mechanical, tumorous or algesic. The therapeutic approach should primarily consider the evolutive potential of the tooth. As a matter of fact, before undergoing any surgical or any complicated surgical orthodontic treatment, the result of our study shows that the eventual absence of any ankylosis image has to be precised on successive profile headfilms taken with an interval of 6 to 12 months. If any evolution is seen, it would be enough to remove the mucous obstacle and then bring the tooth to a normal position by some mechanical means. In the adverse case, the prognosis won't be favorable and leads to either abstention or a dubious therapeutics.
Supernumerary molars are a rather uncommon anomaly. It is more frequent in the upper than in the lower maxillary. Its pathology is often subdued and as a general rule it is detected by X-Ray. In our opinion, its setting shows two processes: --either an extra growth; it is then a normal tooth similar in shape to the wisdom tooth; --or an evagination of the external epithelial sheath giving way to a cone-shaped laterally set tooth.
Through a study of 68 patients, presenting 84 supernumerary teeth all together and, after a thorough survey of the literature, we can now state accurately about the frequency, location, surgery, X-Ray and heredity involved. After recalling and discussing the various pathological theories already set up, a theory has been put forward, more specifically intent on the explanation of frequent supernumerary teeth in the upper front teeth area. Nevertheless, the theories of extra growth and the overgrowth of the external layer remain worth while to explain some other locations.
Concerning three specimens of Bourneville tuberous sclerosis, after a brief recall of general statements about this disease, the authors describe in two out of the three cases published, lesions of buccal mucosis typical of this disease. Besicle hyperplasic lesions, quite common with these patients who are epileptic most of the time, thise lesions mostly consist of fibrous, non inflamatory nodule more frequents on gums, especially one the fore-part. The histologic aspects without being pathognomonic are still quite specific.
The authors mention an observation of lingual necrosis revealing a Horton disease. The set of the usual aspects of the disease was not comprehensive and the inflammatory syndrom was rather weak; nevertheless the diagnosis of a giant cell panarteritis was admitted and a strong cortico-therapy quickly set up which greatly improved the patient. After a brief recall of the main clinical and biological signes of a Horton temporal arteritis, the circumstances, symptomatology evolution and treatment of this particular form of the disease are reviewed through 22 observations found in medical literature.
First described in 1898 under the name of cleido-cranial dysostosis by Pierre Marie and Sainton, this hereditary disease is highly polymorphous and progressive, hence the multiplicity of its manifestations. These involve not only the skull and clavicle, but also the hands, the spine and the teeth. In fact, it is disturbance of growth rather than a dysostosis in the strict sense of the term. Its mode of transmission is dominant. Its pathogenesis is totally unknown.
The authors report a rare association: that of two hereditary dysplasias transmitted in a dominant manner. Cleido-cranial dysplasia or Pierre Marie and Saniton syndrome, a congenital polymorphous disease, affecting the bones during their growth with a Capadepont dysplasia or hereditary opalescent dentine, a condition affecting both dentitons.
