[Selective IgA defect. Clinical importance for stomatology].

The clinical picture of 6 women suffering from selective IgA immunodeficiency were studied in a 2-13 years lasting period of immunological outdoor patients care. Despite of respiratory infections, otitis media, sinusitis, aphtosis and exogenous allergy the first detection of IgA deficiency was delayed til adulthood (mean age 42 years). A case of a 22 years old women with complicated fistula after molar tooth extraction showed the problems of dentistry in such diagnosis.

[Problems of bite injuries in the maxillo-facial region].

Bite injuries by animals in the maxillo-facial-region require special managements of the treating physician or dentist. In the foreground stands the prophylaxis of the rabies. According to the lawful definitions the patient has to be transferred as quick as possible to the next department for rabies and inoculation.

[Report on experiences of one year at the Gondar College of Medical Sciences in Ethiopia. 4. Influence of psychosocial factors on the development of orofacial function troubles].

Functional disturbances of the orofacial system are permanent increasing in the European countries. These are so called psychosomatic diseases which you can find very often in patients with psychic evident personality profile. For the objective evaluation of the structure of personality are described various methods in the literature.

[Report on experiences with a one-year action at the Gondar College of Medical Sciences in Ethiopia. 3. Influence of diabetes mellitus on the teeth supporting apparatus].

Systemic diseases--like diabetes mellitus--are able to injure the local and common resistance of an organism. Therefore we must expect a more intensive and severer progress of gingivitis and periodontitis in diabetic patients in comparison with a non-diabetic control-group. On the Gondar College of Medical Sciences in Northwest-Ethiopia are investigated 77 Insulin-obliged diabetics and 312 persons for control by means of the plaque-Index, the Oral-Hygiene-Index simplified.

[Report of experience during 1-year at the Gondar College of Medical Sciences in Ethiopia. 2. Frequency of caries and periodontitis in Ethiopia].

On the basis of a clinical epidemiological study of 312 patients are made biostatistical investigations about prevalence and Severity of dental caries and marginal periodontitis. The situation of oral hygiene is evaluated by means of the PI of Løe and Silness and the OHI-S of Greene and Vermillion. The DMF/T-Index is used for the evaluation of the set of teeth and the GI of Løe and Silness like the PDI of Ramfjord for the evaluation of the periodontal state.

[The use of sulfonamide containing drug combinations in pyogenic processes of the maxillofacial region].

Compound preparations containing trimethoprim and sulphonamide have been available in the pharmacies of the GDR since 1974. These are the preparations Berlocombin 200 (trimethoprim + sulphamerazine) and Sulprim 120 and 480 (trimethoprim + sulphamethoxazole) which are of great efficacy and have a broad spectrum of action. The mode of action, side-effects, dosage, commercial dosage forms and contraindications are described.

[Sialolithiasis].

Affections of the major salivary glands are relatively rare in stomatology; but according to the indications of several authors, the proportion of sialolithiasis to the total amount of affections of the salivary glands (ranging from 20.5 to 55.5%) is great.

[Results of an analysis of waiting time at a maxillofacial surgery outpatient department of a university hospital].

Waiting periods in public health institutions not only stress the patients and the personnel, but they are also attended by considerable economic disadvantages. For this reason, the waiting periods of patients of a maxillofacial outpatient department in the various examination and treatment stations were analyzed with the help of accompanying leaflets. According to the results obtained, the sequence of examinations and treatments was verified and reorganized with regard to the three main processes: research, medical care, and education and training.

[Microwave therapy in outpatient oral surgery].

The biological action of microwave therapy is due to the conversion of high-frequency electromagnetic waves to heat that is produced directly in the tissue at the radiation area. It is a deep heating procedure of limited range with low-level exposure to the subcutaneous fatty tissue; it may be used in subacute and chronic infectious inflammatory conditions, after surgical interventions, in affections of the salivary glands and of the maxillary sinuses, and also in temporo-mandibular joint disorders and facial neuralgias. As a rule, irradiation by microwaves is only a supporting treatment.

[Effect of the propellants O2 and CO2 on the efficacy of oral irrigation].

The therapeutical results obtained with oral irrigations when O2 or CO2 was used as a propellant air compared with those achieved with compressed air. The assessment of the therapeutical success was based on the periodontal disease index according to Kötzschke and the exsudate heights according to Egelberg. A significant improvement in the periodontal condition was stated in all three groups of patients.

[Change of clinical stomatological parameters in ageing (author's transl)].

Morphological-functional changes occur in the oral cavity also in depended from the age. The morphological changes of the enamel, dentin, dental pulp, periodont, oral mucosa, salivary glands, tongue, maxillary bone and temporo-mandibular-joint change not only the functional cooperation of all parts in the orofacial system. They show effects for the whole body also.

[The quantitative determination of gingival sulcus fluid by means of filter paper strips--an objective measure in the evaluation of success of periodontal treatment?].

The success of various periodontal treatments can be demonstrated by the quantitative determination of the gingival sulcus fluid if these treatments improve the peripheral blood supply. Compared to the manual method of determining the diffusion height of the exudate prior and after periodontal therapy (the extent of exudate reduction being used as a criterion for the degree of regression of the inflammatory circulatory disorder), the photometric-planimetric techniques yield exacter and even more favourable results. Due to its easiness and rapidity, the measurement of the diffusion height of the exudate is, as an additional control examination, useful in assessing the success of periodontal treatment.
