Root surfaces after ultrasonic instrumentation with a polishing fluid.

Objective: The recently introduced Vector system is recommended to be used in conjunction with a polishing fluid containing hydroxylapatite granules (<10 Microm). The aim of the present study was to assess morphologic alterations of the root surface after ultrasonic treatment with the polishing fluid.

Method And Materials: Cementum of 30 freshly extracted human teeth was removed to a level of 4 mm below the cementoenamel junction.
