title: [Clinical studies on the reduction of dental calculus formation by the use of a percent HEDP containing toothpaste].
abstract: In a clinical, uncontrolled double blind test, the effect of a 1% HEDP containing toothpaste on the formation and degree of mineralization of supragingival calculus was examined in 50 subjects over two periods of three month each. Considering all subjects the HEDP-containing paste reduced the new formation of calculus by 34.1% or 41.1% depending on the method of evaluation (CS or VM index) and the mineral content by 20.3%.
