[Volatile compounds in air and oral saliva in healthy people, and in periodontitis and gingivitis patients].

21 healthy persons, 7 patients with chronic generalized periodontitis and 4 patients with chronic generalized gingivitis aged between 18 and 42 years were examined. Air from the oral cavity was collected with a special device; liquid samples were collected by washing the oral cavity with sterile water. Chemical compounds of the air and the washed liquid were analyzed by chromato-mass-spectrometry, gas-adsorption and gas-liquid chromatography.

[The use of a Hydroxyapol-containing zinc-eugenol paste for the filling of dental canals in treating periodontitis].

Comparative assessment of the efficacy of two-staged treatment of patients with chronic apical periodontitis by hydroxyapol-containing paste and zink-eugenol paste demonstrated the desirability of adding hydroxyapol powder in the radical paste for the treatment of apical periodontitis.

[An experimental trial of a hydroxyapatite-based root paste].

Hydroxyapatite-based radicular paste was tried in 12 dogs with experimental chronic periodontitis. Hydroxyapatite, zinc-eugenol, and resorcin-formal pastes were compared. The periodontal status was assessed by morphometric methods.
