[Fundamental elements of maxillofacial orthodontics in the treatment of sagittal maxillo-mandibular disproportions].

The entire cephalometric parameters and specially the alveolar inclinations have to be taken into account, while treating skeletal sagittal discrepancies. In fact, they are either compensatory and should be kept as, or aggravating the basal bone discrepancies, manifesting a neuro-muscular imbalance and complicating remarkably the prognosis. In order to maintain the morphological results, the anatomical corrections have to take into account the neuro-muscular balance concerning position, function and tonicity. That is the concept which provides satisfactory surgical, orthopedic and natural results. We think that the goals of these treatments should not be limited to esthetic or standardized criteria. They have to be achieved in respect to this functional concept and absolutely adapted to each patient.

[Glossodynia].

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.

[The abandonment of treatment in orthodontics].

Orthodontic treatments are frequently given up: a recent study of the C.N.A.M.* has shown a rate of 51%. In spite of lightest and least constraining therapeutic methods, the authors estimate that 27% of the patients stop their treatment before the end. --Looking for the reasons why, they have found a "central nucleus" of about 27% which builds up a constancy of abandoned treatment undeniably in relation with an ethical phenomenon, plainly concerning the individual or the family. --That is to show the advantage of our adapted therapeutic possibilities to answer the patients' requests, and to clearly explain their benefits and their possible difficulties. In other words we have to admit the necessity of a more medical than mechanical approach in orthodontics.

[Aerodontalgia. Report of a case].

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.

[Supernumerary molars].

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.

[Supernumerary teeth].

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.
