[pH-metric efficacy evaluation of interdental spaces cleaning from dental plaque by wood toothpicks].

With the help of local pH-metry the degree of interdental spaces cleaning from dental plaque by wood toothpicks was determined in 18 students-volunteers 21-23 years old. Positive effect was achieved of the wood toothpicks use in the group with preliminary stimulation of metabolic activity of acid producing microflora by 47% solution of sucrose and without it. Expressed change of hydrogen ion exponent in patients with high DMFT index and inflammatory periodontal disease was noted.
