Clinical evaluation of the Jay Sensitivity Sensor Probe: a new microprocessor-controlled instrument to evaluate dentin hypersensitivity.

Purpose: To compare the Jay Sensitivity Sensor Probe (Jay Probe), a new microprocessor-based, pre-calibrated instrument, with well accepted methods used to evaluate sensitivity, i.e. tactile response to the Yeaple Probe, air blast (Schiff scale), and patient responses by Visual Analog Score (VAS).

A clinical study to assess the anticalculus efficacy of a new dentifrice containing a special grade of silica (Colgate Total Plus Whitening Toothpaste): a clinical trial on adults.

The objective of this double-blind clinical study, conducted using the Volpe-Manhold design for studies of dental calculus, was to confirm the supragingival anticalculus efficacy of a formulation variant of a commercially available anticalculus dentifrice. The commercially available dentifrice (Colgate Total Toothpaste) contains 0.3% triclosan and 2.
