[Ways of solving the problem of dentin hypersensitivity in children after professional oral hygiene].

Aim: To design an algorithm of decreasing dentin hypersensitivity in children after professional oral hygiene.

Methods And Materials: Intact teeth extracted for orthodontic reasons in children and adults were involved in the pilot study. The enamel surface was cleaned by manual instruments and then polished with polishing pastes containing sodium bicarbonate, fluoride, calcium and phosphates. The results were studied with the help of a scanning electronic microscope. 60 14-15 years schoolchildren, the residents of Krasnogorsk, a town in the Moscow region, took part in the study. All of them were diagnosed dental plaque (K03.6) and underwent professional oral hygiene by manual instruments. Then the teeth were polished with polishing toothpastes. To reduce dentin hypersensitivity after these procedures the SENSODYNE Rapid Relief toothpaste was applied.

Results: The pilot study showed a destructive effect of a manual instrument on the tooth enamel especially in children. The data of the scanning electronic microscope demonstrated that the manual method with the use of polishing pastes containing sodium bicarbonate, fluoride, calcium and phosphates led to a significantly lower negative effect of this manual method on the tooth enamel both in children and adults. The application of SENSODYNE Rapid Relief by children at home after professional oral hygiene led to a decrease of dentin hypersensitivity by 65, 37%.

Conclusion: The designed algorithm of the children's follow-up procedures after professional oral hygiene includes the application of polishing pastes containing sodium bicarbonate, fluoride, calcium, phosphates and the Sensodyne Rapid Relief toothpaste at home. This helps to minimize negative consequences of manual tooth plaque removal in case of professional oral hygiene.
