Jaw cyst arises usually as a complication of disease of a tooth as a result of which chronic inflammatory process at a top of tooth's root with formation of a cyst develops. In more rare cases it arises from an environment of the follicle surrounding crownwork of a tooth, at infringement of its process dentition. Therefore such a cyst refers to follicular.
Unlike it root meets much more often as disease of a teeth repeatedly exceeds number of their cases complicated dentition. Root cyst develops on a background of a chronic inflammation, grows slowly, but steadily. Increasing in volume, constantly presses on a bone fabric surrounding it which forcedly "recedes", releasing a place for growing cyst.
It is not enough, or absolutely of itself not showing, cyst it is visible, only when appears bulge of a jaw with thinning its external dense bone scuts, on what the patient or its associates pays attention. Often at x-ray of jaw in this or that occasion cyst is found out as a casual find.
Its growth sometimes attracts so significant destruction of a bone of a jaw that leads to its spontaneous crisis. Besides penetration into a cyst's cavity pus-producing microbes can cause heavy inflammatory process with involving in it of a bone brain of a jaw and development of an osteomyelitis. Regeneration root cyst is possible as is long current process in a cancer tumor.
Treatment:
Surgical. At the small sizes carrying out of operation in out-patient conditions is admissible. The recommendation: the periodic control (once a year) tooth-maxillary system by means of x-ray.

A technique for treatment of patients with cystic involvement of femoral neck-trochanteric part
In Russian Ilizarov Scientific Center "Restorative Traumotology and Orthopaedics" the rational technique for reconstructive surdies on the basis of transosseous osteosynthesis was worked out. This method allows not only to get rid of destruction focus at a single stage, but to eliminate the existed associated orthopaedic pathology as well.
The indication to operative intervention is:
- Absence of positive dynamics reparative processes in the pathological center at conservative treatment;
- Dynamic increase in the sizes of the center of destruction;
- Numerous pathological crises or threat of their occurrence;
- Availability of deformations of a segment with shortening or without it;
- Relapses after earlier executed operative interventions.
The given way is applied at 7 patients with cystophorous defeat of a proximal area of a femur in the age of from 8 till 16 years (men – 5, women – 2).
Earlier at patients 11 pathological crises in occasion of which it was applied conservative (a plaster bandage - 5, skeletal extension - 2) and operative (a regional resection - 3, an intraperiosteal resection - 1) treatment were marked.
At receipt in a hospital at five patients it was marked coxa vara from 1200 up to 850, at 2 - a plough valga (1350 - 1450). In two cases there was a shortening a segment on 3 and 4 sm accordingly. The casualty finiteness was 3 cm longer (due to a hip) than contralateral at two patients.
The size of distribution of pathological process on bones was various and made from 4 up to 10 cm.
Terms of an osteosynthesis the device have made 106,7±14 days. Favorable outcomes of treatment are reached in all cases. Results were estimated in a view of following factors:
- Presence of a painful syndrome;
- Stability in a place of operative intervention;
- Presence of deformation, shortening of a segment;
- Volume of movements in adjacent joints;
- Occurrence of relapse of disease.
The remote results of treatment are studied in terms from 1 year till 5 years.
Thus, use of the developed method on the basis of perosseous an osteosynthesis at treatment of patients with cystophorous defeat of a femur, providing performance directed osteotomy, receptions of a compression and distraction fragments as separately, and in their combination, allows to receive stable, recurrence-free results with adequate orthopedic and functional rehabilitation and to reduce term single-stage treatments in 1,5-2 times.

Neuralgia of a figurative nerve
The neuralgia results from traumas, the intoxications caused by diseases of a liver, kidneys, malignant tumours, salts of heavy metals, bacterial toxins, alcohol, metabolic infringements at a diabetes, chronic processes in a gastroenteric path, etc. Can develop at a flu, a malaria, a tuberculosis to be the first clinical display of infectious-allergic process in nervous system. The certain role in occurrence plays Neuralgias hypoxic factor, for example at atherosclerotic defeat of vessels, other diseases of cardiovascular system, anemias. In some cases the reason of the Neuralgia to establish it is not possible.
The attack-like pain extends on a course of a nervous trunk or its branches. The pain can be sharp, shooting, tearing, to be accompanied by sensation of burning. There are attacks spontaneously or at movements, under influence of a touch, overcooling of an emotional overstrain. Localization hurt corresponds to a zone of a innervation the certain nerve, characteristic painful points, for example points the Point, Bekhterev often come to light.
Features of clinical displays depend on localization of process.
The neuralgia of a trigeminal nerve can be result of a trauma of the person, the transferred inflammation of bosoms of the nose, a sick teeth (pulpitises), even a wrong bite. An attack hurt at a neuralgia of a trigeminal nerve can arise at any moment: as reaction to hot or cold food, to loud sounds, too bright light, even during cleaning a teeth. The attack begins with occurrence of "harbingers" - an itch, sensation of a “creeping”, and is then shown in the form of sharp, "shooting", up to tears of a pain which lasts no more pairs of minutes. In attempt to wait an attack, the person fades on seat, questions answers tersely, hardly slightly opening a mouth.
Treatment of a neuralgia
To removal of an attack of a neuralgia apply or a complex analginum + amidopyrine or carbamazepine. By the way, in opinion of some doctors, strong irritation all of the same zones during an attack, can stop it.
The range of methods of treatment of a neuralgia is rather wide - from physiotherapy up to surgical measures (when do not help medicines). The good effect in treatment of a neuralgia gives application of acupuncture, pulse currents of a low pressure and low frequency, magnetic and electromagnetic fields, infra-red and ultra-violet radiation, ultrasound, electrophoresis medicinal substances.
