[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. High accuracy of the method allows to use it in the groups with relatively small number of subjects.
