[The use of sulfonamide containing drug combinations in pyogenic processes of the maxillofacial region]. / Zum Einsatz von sulfonamidhaltigen Kombinationspräparaten bei pyogenen Prozessen im Kiefer-Gesichts-Bereich.

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. Clinical tests have shown that a success-rate of 80.3% may be expected from treating pyogenic processes. Compound preparations of this kind might fill, at least in part, the gap caused by the increasing ineffectiveness of penicillin which is due to bacterial resistance.

[Effect of the propellants O2 and CO2 on the efficacy of oral irrigation]. / Einfluss der Treibgase O2 and CO2 auf die Effektivität der Mundduschbehandlung.

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. Though only the exsudate values for the O2 group were significantly better than those for the compressed air group, being the only difference between the groups which was significant, the greater efficiency of the O2 and CO2 application (compared to compressed air application) is, nevertheless, obvious and interpretable. The therapeutical results obtained permit the statement that a technically perfect device and the further increase of the partial pressure of O2 or CO2 in the irrigation fluid will lead to even better therapeutical results, for which purpose the suggestions given should be considered in establishing the indication. The favourable results achieved with compressed air testify to the beneficial action of each irrigation or spray treatment.

[The quantitative determination of gingival sulcus fluid by means of filter paper strips--an objective measure in the evaluation of success of periodontal treatment?]. / Die quantitative Bestimmung der gingivalen Sulkusflüssigkeit mittels Filterpapierstreifen--ein objektiver Massstab bei der Erfolgsbewertung der Parodontalbehandlung?

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.

[Determination of the most favorable impulses in oral irrigation using a new device]. / Beitrag zur Abklärung der Frage der günstigsten Impulsgebung bei der Mundduschbehandlung mit einem neuen Gerät

The present paper discusses the question of the most favorable kind of impulsing the flow liquid in oral irrigation. A pulsation synchronous with the user's heart rate is considered optimal. The utilization of electron timing components which operate solenoid valves offers the possibility of securing (without complicated measuring and controlling systems) a synchronization of the pulsations of the water flow with the patient's heart rate which is sufficient for practical purposes since an acceleration of the blood flow is primarily achieved by removing the venous stasis.

[Evaluation of studies on the optimal impact pressure of the fluid stream in mouth irrigation]. / Auswertung der Untersuchungen über den günstigsten Aufpralldruck des Flüssigkeitsstromes bei Mundduschbehandlung

To make comparable literature data on liquid pressures achieved with different devices and nozzles in oral irrigation, it is necessary to indicate not only the initial pressure in the feed pipe but also the actual pressure of the liquid jet upon the tissue. Using a special technique of his own, the author demonstrated that the pressure in the nozzle is considerably reduced by employing a supplementary swirl nozzle. The hypothesis that, when treating inflammatory periodontal diseases, the impact pressure of the liquid jet should not exceed considerably the inner pressure of the arterioles, capillaries and venules was corroborated.

[Presentation of a portable mouth irrigator. Possibilities of improving the cleansing effect and the activation of the peripheral blood flow in periodontal prophylaxis and therapy]. / Vorstellung eines transportablen Mundduschgerätes. Möglichkeiten der Verbesserung des Reinigungseffektes und der Aktivierung der peripheren Durchblutung in der Parodontalprophylaxe und -therapie

Oral irrigation is an approved procedure in periodontal prophylaxis and therapy. The author describes a portable oral irrigator and explains its design principle and working. By using new constructional elements (such as the swirl nozzle at the front of the mouthpiece) and by impulsing individually the flow of liquid via solenoid valves which are controlled by timing components, it is possible to improve the cleansing effect as well as the massage effect (in the sense of an activation of the peripheral blood-supply to the periodontium).
