title: [Wedge-shaped defects of the neck of the tooth in regular brushing with an amine fluoride gel].
abstract: Gingival recession and wedge-shaped defects are caused mainly by incorrect tooth brushing procedures. The aim of this epidemiologic study was to determine if in addition there is a relationship to the regular use of an amine fluoride gel (pH 5.2) applied by a toothbrush. In a regression analysis, the effect of age, sex, education, toothbrushing frequency, gingival bleeding (PBI) and use of the gel on the occurrence of wedge-shaped defects was investigated. Similarly, the influence of these variables on the occurrence of gingival retraction without any hard tissue defect was investigated. Both types of lesions showed a statistically significant relationship to age and PBI. Moreover, use of the amine fluoride gel was significantly and negatively correlated with the occurrence of wedge-shaped defects.
