“…Die folgenden Messungen und Parameter wurden durchgeführt und untersucht: -die mastikatorisch stimulierte Speichelfließrate (in ml/min, stimuliert durch zweiminütiges Kauen eines Paraffin-Kör-pers); -measurement of volatile sulfur compounds in ppb using the Halimeter ® sulfide monitor (Interscan Corporation, Chatsworth, CA, USA or Ansyco GmbH, Karlsruhe, Germany). Halimeter ® readings between 70 and 110 ppb represent the normal range, above a value of 150 ppb can be described as manifest oral malodor [7]; -the modified gingival index according to Löe & Silness [21] (0 = no inflammation or redness, 1 = slight inflammation, slight redness, slight swelling, 2 = moderate inflammation with redness, edema and bleeding, 3 = severe inflammation, redness, edema, tendency to spontaneous bleeding, ulceration); -the modified plaque index according to Silness & Löe [36] (0 = no plaque based on inspection and probing, 1 = thin, probeable film of plaque, 2 = continuous plaque covering in the sulcus area, 3 = thick dental plaque, interdental space filled); -the bleeding on probing index [17] (0 = no bleeding, inactive, 1 = bleeding, active).…”
