The unilateral resection of the lower jaw results into displacement of the fragment preserved. Usually a driving device of the lower jaw is worked out for the treatment of the deviation that slides along the vestibular surfaces of the upper lateral teeth and restricts the articular disturbances. The authors task is to determine clinically the harmful forces of friction, proposing, at the same time, an original roller driver for their reduction.

A comparative study was carried out between two groups of children--115 prematurely born and 4830 full-term babies in order to establish the effect of pregnancy duration of the origination of hypomineralization of the milk teeth. The effect of the following factors was also studied and compared: complications of pregnancy, feeding of the newborn and diseases during early childhood of full-term and prematurely born children. The authors established that the prematurely born children were a risk group for the origination of milk teeth hypomineralization. The complications of pregnancy, mixed or bottle feeding as well as the frequent illnesses are additional aggravating factors in the origination of milk teeth hypomineralization. The authors recommend timely follow-up care and prophylaxis of all prematurely born children.

Thirty two children, aged from 6 to 14 were studied by the rheoencephalographic method during general halothane and laughing gas anesthesia, stomatologically treated under out-patient department conditions. The quantitative analysis of the rheoencephalographic curves made of the method of differentia, the data being compared one hour before the general anesthesia, during the stage of surgical anesthesia and one hour after it. Statistically significant data were established showing pulse supply improvement and reduction of vascular tone of the brain blood vessels during general anesthesia and one hour after it. The expedience of the application of the rheoencephalographic method during general anesthesia is stressed upon as well as the potentialities of its application in the stomatological practice. The positive qualities of the method of general anesthesia applied for the stomatological treatment of children under out-patient department conditions are confirmed.

The authors have studied the melanocytic population in oral mucosa (Dihydorxyphenyl alanine, silver impregnation, hematoxilin-eosin) of 20 patients (10 with Lichen ruber planus and 10 with Alopecia areata). The melanocytic population in oral mucosa ranges from 605 to 1555 cells per m2 (964 +/- 312 on the average). Normal population, in case of lichen planus of oral mucosa, is disturbed in the regions of the pathological process. The deviations established are discussed.

A clinical case is described for removable articulartelescopic bridge prosthesis of a defect, restricted distally by loose teeth (II degree of pathological looseness) and 3/4 atrophy of the alveolar bone. Compromised prosthesis has been realized by restriction and equalizing the mobility of the bridge-carriers by an articular and telescopic connection. Bulagarian articular elements have been used (TCE) for a soft contact and stabilization and sinking conical telescopes.

A brief literature review is presented at the beginning of the paper, revealing that the necrotic fasciitis of odontogenic origin in the region of head and face is rarely observed with just a few communications in literature. Proceeding from the fact that term has not been introduced so far in the Bulgarian stomatological literature and that no communications are available about that disease, the author describes a 52-old female patient, affected by severe diabetes. Grave necrotic fasciitis in the infratemporal, temporal, parietal and occipital region advanced after the extraction of lower molars without any pretreatment on the background of the diabetes. The patient was healed by radical necrotomy of the affected fasciae and subcutaneous adipose tissue and via active antibiotic, general tonic and antidiabetic therapy.

The authors describe three patients with lymphosarcoma--nodular form for a 13-year period, involving the cervical lymph nodes. The rarity of the disease is emphasized as well as the difficulties in the differential diagnosis with the chronic sialadenitis and lymphopathies. The clinical interpretation of the disease is difficult because of the lack of specificity in the clinical course and paraclinical studies. The accurate diagnosis is only possible by a pathohistological study. The authors underine that the nodular form of lymphosarcoma should be given consideration in the differential diagnosis of the diseases of lymph apparatus in cervical region.

A method has been developed for modelling, with profile wax, of absent dental tissues for inlays with the application of one-stage model casting. Close contact is guaranteed by the application of the method--point, free interdental space, exact construction of the "tail" of the inlay in the aproximal sides of the tooth and a possibility of great economization of metal while working out the inlays on highly destructed teeth.
