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